Regenerative bricks are widely used in industry, construction and other aspects because of their heat resistance and pressure resistance. There are three main types:
1. Burning regenerative bricks:
The fired regenerative brick is made of fine ingredients of magnesia and chrome ore, and the content of Cr2O3 is adjusted according to different needs. The product has good thermal stability and high temperature performance, and is widely used in cement kilns, non-ferrous metallurgical furnaces, etc.
2. Directly combine heat storage bricks:
heat storage brick
The directly combined heat storage brick uses chrome ore and high-purity magnesia with low impurity content as raw materials. Good high temperature performance and strong slag corrosion resistance. Resistant to cement clinker erosion. Widely used in non-ferrous metallurgical furnaces and cement rotary kilns.
3. Semi-recombined heat storage bricks and recombined heat storage bricks
Semi-recombined heat storage bricks and recombined heat storage bricks use part or all of fused sand (electrically fused synthetic sand) as raw materials, fine ingredients, high pressure molding, ultra-high temperature calcination, good particle bonding, high product strength, and stable volume Good performance, widely used in RH, VOD, AOD and other off-furnace refining devices, non-ferrous metallurgical furnaces, etc.
