1, Description of Sillimanite Block For Glass Kiln Pond Bottom
Sillimanite Block For Glass Kiln Pond Botto is a high-grade refractory brick developed and produced to extend the service life of the furnace bottom. It is a new product developed by virtue of the application effect of sillimanite in tin bath. After use, the effect is very significant, which extends the service life of the traditional clay bricks by 3-5 times, and effectively reduces the repair times and costs of the furnace. After calcination, the performance and structure of sillimanite under high temperature have been greatly improved, with good thermal shock resistance, small thermal expansion rate, needle like or columnar mullite phase grid structure, good alkali corrosion resistance, etc. Therefore, the sillimanite bricks produced from the calcined sillimanite raw materials meet the requirements of the bottom environment of the tank kiln, especially the damage caused by the further diffusion of hydrogen, Effectively extending the service life of the pool bottom.
