热矿筛筛板是冶金部要求三十项长寿化备件之一,由于筛板的工作条件非常恶劣:承受800~1000℃的高温,激烈地磨损,连续运转的冲击和振动等等,致使筛板的使用寿命不长,直接影响到烧结矿的产量和高炉焦比的降低。国内外对筛板的材料进行了大量研究。国内多用铬锰氮钢制造,使用寿命三个月左右。国外一般用高铬钢、316、380不锈钢制造,使用寿命2~6个月,还没
Thermal sieve Sieve Sieve is the Ministry of Metallurgical requirements of thirty one of the long-life spare parts, as the sieve of the working conditions are very harsh: to withstand 800 ~ 1000 ℃ high temperature, intense wear and tear, continuous operation of the shock and vibration, etc., resulting in sieve Plate life is not long, a direct impact on the production of sinter and reduce the blast furnace coke ratio. Domestic and foreign material on the sieve a lot of research. Domestic use of chromium manganese nitrogen steel, the service life of about three months. Foreign high-chromium steel, 316,380 stainless steel, life of 2 to 6 months, not yet
