Product description of Tabular corundum
Tabular corundum is a sintered corundum crystal with complete shrinkage, low impurity content, small pores, low remelting shrinkage, good thermal shock stability, high temperature corrosion resistance and excellent creep properties.
Features of Tabular corundum
- Tabular corundum is well developed, completely shrinks, and has low water absorption
- Stable raw materials, easy process control and stable product quality
- Do not add reducing agent, and avoid other substances polluting the product in the process
- It is an excellent super high temperature refractory material, which can withstand high temperature and can be used at 1800 ℃
- Good hardness and abrasion resistance, Moss hardness is 9.0, which can be used as high abrasion resistant refractory
- Not only that, but also has good heat resistance vibration and high temperature resistance Krimo modification force, which is widely used as refractory castable or refractory brick
- Excellent corrosion resistance, excellent high-temperature thermochemical stability, molten iron and molten iron corrosion resistance
