High Quality Zircon Refractory Block with Liquid Erosion Resistance for Glass Furnace
The Description:
Zircon brick is acidic material, which is made of natural zircon sand as raw material. It has strong slag resistance, low thermal expansion rate, lower thermal conductivity with increasing temperature, high softening point under load, high wear resistance and good thermal shock stability, and has become an important material in various industrial fields. With the development of continuous casting and vacuum degassing technology in metallurgical industry, zircon brick has been used more and more widely. Zircon brick is made of single zircon stone sintered zircon brick, and zircon stone as the main raw material, adding the appropriate sintering agent (such as refractory clay > made of zircon brick. In order to improve the performance of zircon bricks, there are also special zircon bricks with other ingredients (such as zirconia, high bauxite, fused corundum or chromium oxide).
