Why choose regenerative bricks for rotary kiln?

2022-02-15 15:42:45

Heat storage bricks can be called clay bricks according to the content of less than 55%. They are neutral refractory materials made of bauxite or other materials with high alumina content. It has high thermal stability, and the refractory temperature is around 1700°C. It is used for the lining of glass melting furnaces, cement rotary kilns and steelmaking electric furnaces. Of course, there are also some high-alumina clay bricks and high-alumina brick products with high load softness, low creep and low pores, and high-alumina brick products. According to different application requirements, the ratio of raw materials is very important in production. The following heat storage brick manufacturers will specifically analyze why the rotary kiln should choose heat storage bricks:

Regenerative bricks are mainly used for the lining of blast furnaces, hot blast stoves, electric furnace roofs, blast furnaces, reverberatory furnaces and rotary kilns. In addition, regenerative bricks are also widely used as open hearth regenerative checker bricks, plugs for pouring systems, nozzle bricks, etc.

Regenerative bricks and clay bricks are not only different in alumina content. Their production processes are similar, but the clinker content in the mix is higher, which can reach 90-95%, and the firing temperature is also higher than that of clay bricks. Many, the first and second grade high alumina bricks are mostly used in tunnel kilns, blast furnaces, furnace tops, reverberatory furnaces, rotary kiln linings, etc.

The production process of heat storage bricks and multi-clinker clay bricks is similar, the difference is that the proportion of clinker in the mix is higher, which can be as high as 90-95%. The temperature is higher, and the heat storage brick is generally 1500-1600 ℃ when fired in a tunnel kiln. The production practice has proved that the high alumina clinker is strictly selected and graded before being crushed, and it is graded and stored, and the fine grinding method of bauxite clinker and combined clay can improve the product quality.
