Bensal for Molten Aluminum Service.CHEEKTOWAGA, N.Y.--(BUSINESS WIRE)--Nov. 25, 1998--Benchmark Structural Ceramics Corp. manufactures structural ceramics and specialty refractory refractory Material that is not deformed or damaged by high temperatures, used to make crucibles, incinerators, insulation, and furnaces, particularly metallurgical furnaces. components. Recently Benchmark has developed Bensal(tm), a sialon-based reaction bonded material, suitable for molten aluminum service. Benchmark believes the qualities of its Bensal tubular tubular /tu·bu·lar/ (too´bu-lar) 1. shaped like a tube. 2. of or pertaining to a tubule. tubular 1. pertaining to renal tubules. 2. pertaining to fallopian tube. shapes are far superior to any similar product in the marketplace as well as being reasonably priced. Bensal thermocouple sleeve has unsurpassed thermal shock Thermal shock in mechanical models Thermal shock is the name given to cracking as a result of rapid temperature change. Glass and ceramic objects are particularly vulnerable to this form of failure, due to their low toughness, low thermal conductivity, and high strength, allowing it to be immersed im·merse tr.v. im·mersed, im·mers·ing, im·mers·es 1.

Benchmark expects the material to last as long as any other sialon-based product on the market. Based on this new development, Benchmark started to produce one end closed protection sleeves: thermocouple protection tubes and heater tubes, and both ends open vertical immersion immersion /im·mer·sion/ (i-mer´zhun) 1. the plunging of a body into a liquid. 2. the use of the microscope with the object and object glass both covered with a liquid. and riser tubes, bubbling and gas injection tubes and plugs. -0-
