What are Refractory Materials?

There was a time when I would simply pull out my trusty Webster’s Tome. I would efficiently thumb to the desired entry, proudly making full use of the alphabetical skills acquired through years of primary education. Voila! Having quickly located the desired term, I would faithfully and obediently parrot the appropriate definitions. But times have changed, and I have kept up with them. I now depend, as I’m sure is true for most of us, on Google and Wikipedia for my primary didactic guidance.

So I Googled “Refractory”.

Webster could never have anticipated the boundless diversity of definition declared relative by Google’s algorithms! You may enjoy looking for yourself, but let me assure you that for our purposes, refractory is not “the recovery phase after orgasm during which it is physiologically impossible for an individual to have additional orgasms” http://en.wikipedia.org/wiki/Refractory_period(sex)

And did you know that in the religion of the Vedic period in India, there are certain words that, when used as a Mantra, affect a spiritual transformation in the individual repeating them? Om (or Aum) is perhaps the most well known. The meaning of the words (and the self) becomes lost in the rhythm of repetition. The void that this loss creates invites change and hopefully an accompanying enlightenment. 

How in the world did I get from “Refractory” to refractory Karmas? The Six Degrees of Separation of People states that each person on Earth is only 6 acquaintances from every other person. I’d like to be the first to declare a similar relationship for information, my just conceived and soon to be famous Six Clicks of Separation of Information theory, each topic searched for is only 6 clicks away from all other topics

I’m tempted yet again to abandon this new hyperlink knowledge fest and dust off my trusted old tome. But I never do. I love this new world of fast and easy information. I love having the world’s largest library sitting on my desk. Maybe I won’t become famous for my theory, but I’ll bet one day I’ll learn to use technology as efficiently as that old dictionary.

In the mean time, you’ll have to read more of the blog to know what our discussion is all about. Since I already know, I’m just going to go practice my mantra. “Aum refractory, Aum refractory, Aum refractory…”

New adhesives to optimize filter manufacturing

Filters are used in many different areas and applications to clean air and liquids. When producing consumer and industrial goods, adhesives play a decisive role. To meet the high expectations of industry, Henkel invests in research and develops new technologies. At the FILTECH 2011 trade fair, Henkel will be presenting an up-to-date product portfolio for construction of modern filter systems. 

Henkel will be presenting a cold-cure rigid polyurethane foam adhesive for effective end-cap bonding of liquid and air filters namely Macroplast UK 8524. When compared to conventional products, this adhesive offers numerous benefits: Unlike PVC plastisols, Macroplast UK 8524 can be used and cured at room temperature. This reduces both the cure time and high temperature required which results in significant energy cost savings during the manufacturing process. It also lowers production costs and has a positive impact on environmental performance. Further cost savings are achieved thanks to the rigid foam adhesive’s processing properties: Macroplast UK 8524 foams without needing any further additives, achieving a volume increase of up to 270 percent and forms a closed-cell glue foam with a density of 0.4 g/cm³. As a result, less adhesive has to be used than before, reducing product costs by up to about 30 percent. Another feature worth mentioning is the adhesive’s excellent resistance to engine oil, which makes it suitable for use in automotive industry applications as well. 

In addition Henkel has also developed two other adhesives, Macroplast UK 8630 and 8640 which were specifically engineered for use in transport and other applications. These polyurethane-based products are permanently resistant to bio-diesel and other bio-fuels, thus ensuring the durability of fuel filters in retrofitted vehicles. Another plus is their high temperature stability: With a glass transition temperature (TG) of over 100°C, the adhesives can be used in many different applications. 

Another product from the Macroplast range that will be showcased at FILTECH 2011 is primarily intended for stabilizing water filters. The larger the diameter of the filter, the more unstable it becomes in use. Filters for water and beverage production are frequently very large, and have to withstand high pressures. Henkel has responded to the special needs of the industry by adding a new product to its standard range – Macroplast CR 3526/4200. This is a rigid filter adhesive for stabilizing large-diameter filters. Manufacturers benefit from this new technology by achieving better quality and hence greater durability of the filters. 

Different applications need different adhesives, and Macroplast UK 178 is the preferred choice for spiral wound reverse osmosis filters. This adhesive has already established itself in the USA and Asia in water purification and gas cleaning filters. Macroplast UK 178 meets the highest standards and has been certified in accordance with the U.S. drinking water standard NSF 61. As this product has been very successful overseas, Henkel is now introducing this adhesive in Germany as well. 

Visitors can learn all about the latest product innovations and how Henkel adhesives have made a positive contribution to the filter industry at stand B5 in Hall 1 at FILTECH 2011.

Refractory Material Reduces Furnace Downtime for Aluminum Die

Reducing furnace downtime is a key element in maintaining adequate productivity in foundry operations. One of the most common maintenance problems encountered in any given foundry is the repair and replacement of the refractory materials used to line the melting furnaces. The linings of aluminum melting furnaces are constantly exposed not only to high temperatures, but also other adverse conditions that may include impact and gouging when aluminum ingots are charged into the furnace.
Another main contributor to the deterioration of aluminum melting furnace linings is the formation of alumina or dross on the surface of the melt which can penetrate a refractory brick lining, thus requiring constant maintenance and repair. In many instances, a furnace may have to be repaired monthly and/or completely relined every one to three years in order to keep it operational.
A two-part refractory system (ThermbondR) has been developed by Stellar Materials, Inc., Delray Beach, FL, within the last several years and is showing promise as a durable, alumina-resistant furnace lining material. Below are two case studies that describe the application of this stable, abrasion-resistant refractory material and the benefits realized by two aluminum melting operations.

AIRO DIE CASTING
Airo Die Casting, Inc., Loyalhanna, PA, was founded in 1975 as a producer of aluminum die cast compressor blades for the nuclear industry. The company has grown significantly and is currently serving a variety of specialized industries including telecommunications and transportation. The company's newly designed, 60,000 square foot manufacturing facility provides the ideal environment for a full range of service capabilities including tool design and construction, impregnation, pressure testing, chromating, assembly and powder paint.
Prior to redesigning the manufacturing facility, Airo Die Casting used gas-fired crucible furnaces at the individual die casting machines to produce the melt. Over the last several years, new equipment and methods have been implemented at the casting stations that outstripped the capacity of the local furnaces. By upgrading hydraulics and control systems on the casters, and through the use of reciprocators and automatic ladlers at each casting station, each machine is now capable of producing more parts than the capacity of the old furnaces.
To meet the need for more capacity, the company added a 40,000 pound gas-fired reverbatory furnace from Schaefer Furnaces, Inc., Dayton, Ohio. While finalizing the specifications for the new furnace, Schaefer engineers warned Airo about aluminum oxide that is inevitably generated in furnaces of this type at the surface of the molten metal where it contacts the air. Aluminum oxide has a tendency to penetrate and build up on conventional high-alumina refractories. As the aluminum oxide builds up, it gradually reduces the furnace's capacity and can even deform the walls of the furnace. Under normal circumstances, it is feasible that a furnace would have to be shut down every six months for major repairs costing the company thousands of dollars in materials, labor, and production time until the furnace is back in service.

DURABLE REFRACTORY
To combat the problem of aluminum oxide build up, the furnace manufacturer recommended the use of the Thermbond family of engineered refractories instead of conventional refractory materials. This two-part system consists of a dry formulation and a liquid activator (Fig. 1).
These materials are supplied as pre-measured components that are added together to form a unique ionically bonded refractory. The key advantage of this material in aluminum foundry applications is that it is completely and naturally non-wetting to aluminum without the use of additives. This feature allows oxides to be easily removed during nightly cleaning operations without damaging the underlying refractory, ultimately resulting in a longer lining life. Other refractories typically use additives to achieve non-wetting characteristics, which eventually oxidize out of the products causing them to lose their effectiveness.
Another advantage of this Al2O3-resistant refractory is that its high early strength reduces installation time and allows furnaces to return to service faster. The refractory reaches a high compressive strength within an hour of casting and typically cures within a few hours after it is applied with no external heat required. The material bonds extremely well to itself and to other refractories so it can easily be repaired or veneered for extended service. In most applications, this refractory can be put into service immediately after bake-out.

RESULTS
Very soon after the new furnace was installed, the metal tenders noticed a major difference in maintenance requirements. Much less than the expected amount of aluminum oxide had adhered to the walls of the furnace and the oxide was removed with a minimum of effort (Fig. 2). Instead of spending several hours cleaning the furnace, it took less than 15 minutes. The easy removal of the aluminum oxide deposits indicated that the refractory was extremely durable since the main failure mode of the earlier refractory was breaking off along with the oxide.
After a little experience, a routine maintenance schedule was developed. Once per shift, a flux degassing wand is run around the walls of the furnace to soften up the oxide buildup. Then at the end of each shift, a steel "rake" is used scrape the walls. This minor amount of cleaning is sufficient to remove any build up of oxide and maintain the refractory lining at production standards.

LONG-TERM PERFORMANCE
For two years, the furnace has run 24 hours per day, six days a week and 12 hours on Sunday with only two shut downs (once related to damaged wiring and another for cold cleaning and inspection). During inspection, it was found there was no significant growth of oxide and no penetration of the Thermbond by alumina. The walls were made smooth again using Formula Patch and to date, the refractory material wall is still in excellent condition (Fig. 3). The walls are nearly as flat and smooth as when the furnace was first installed. Based on current experience, it is estimated that the furnace will provide another 24 months of continuous service before requiring another shut down for cold cleaning and/or replacement.
The cleanliness of the new furnace has also improved product quality. Airo has received no reports from customers concerning the presence of oxide inclusions in any of their products.
