一、工频炉碱性炉衬的探讨 1.炼钢的基本反应: 根据钢液对炉衬的要求,熔炼高锰钢时,炉村应具有高的抗腐性、良好的热稳定性和较小的体积变化,高温下有较高的耐压强度,还必须要有低的导热率和导电率,才能适应多品种多牌号钢种的需要。而酸性炉衬——石英砂(SiO_2),在整个熔池中SiO_2永远处于过量状态。因此炉渣、钢液对炉衬的作用是很明显的,同时在熔炼过程中炉料本身带入大量的杂质,如:FeO、MnO、回炉料中粘附的CaCO_3、CaO(因采用石灰石型砂造型),以
First, the basic frequency of furnace furnace lining 1. The basic reaction steelmaking: According to the liquid steel lining requirements, high manganese steel melting, the furnace village should have high corrosion resistance, good thermal stability and small Of the volume change, high temperature high compressive strength, but also must have low thermal conductivity and electrical conductivity, to adapt to the needs of many varieties of multi-grade steel. The acidic lining - quartz sand (SiO 2), throughout the pool of SiO 2 is always in an excessive state. Therefore, the effect of slag and liquid steel on the lining is obvious. At the same time, the charge itself brings in a large amount of impurities such as FeO, MnO, CaCO_3 and CaO (due to limestone sand molding) To
