Iron making plays an important role in the iron and steel production, distribution chute is an important part of the blast furnace, especially in furnace top.

Distribution chute is located in the top of furnace chamber,where the temperature is very high and has bad working environment, the highest temperature can reach up to 700 degrees or above when it has bad blast furnace conditions. Each batch of furnace burden constantly rush at distribution chute from material control valve, but we can not observe the working condition and their damage from the outside,so we must request chute has high reliability and long service lifetime.

Short service lifetime is a universal problem for blast furnace chute all over the world, usually 6-10 month. Distribution chute made of Zhangjiagang VAUTID YaoYu wear resistant steel plate is special designed against high abrasive wear and temperature, practice shows that the applications of the VAUTID overlay wear plate can work at least t times better than the original.
