What Are The Common Refractory Materials For Blast Furnace?

In the early stages of long process steelmaking, the blast furnace is a shaft furnace that burns coke by blowing hot air and reduces iron ore to hot metal. It is a thermal device for the continuous production of iron in a high temperature and reducing atmosphere.

Refractory Materials for Blast Furnaces

  • 1.Anhydrous clay

Anhydrous clay is a kind of refractory material used for sealing iron mouth. It has the characteristics of good filling, easy opening, corrosion resistance, improvement of furnace environment, stable iron mouth and so on.

  • 2.Graphite block

Graphite block is a kind of high temperature refractory material, made of high purity graphite. Can be customized according to customer needs, with good thermal conductivity, high temperature resistance, corrosion resistance and other characteristics.

  • 3. Silicon carbide brick

Silicon carbide brick is a refractory material made of silicon carbide as the main raw material. The product has the characteristics of good wear resistance, corrosion resistance, high temperature strength, good thermal shock stability, high thermal conductivity, small thermal expansion coefficient and so on.
