稀土合金采用何种加入方法对于生产稀土钢来讲是极为重要的,因为稀土元素能否与钢液充分作用是发挥稀土在钢中作用的关键因素。目前国内外采用稀土合金加入方法甚多,其中有稀土合金块的炉内加入法和钢包加入法,稀土金属丝的喂入法,稀土金属棒在锭模的吊挂法,稀土合金粉在钢包喷射法等等,各种加入方法各有特点,应因地制宜充分加以利用,以求获得最佳性能的稀土钢。 It is very important for rare earth alloy to be used in the production of rare earth steel because whether rare earth elements can fully function with molten steel is the key factor to play the role of rare earth in steel. At present, there are many methods for adding rare earth alloy both at home and abroad, including the method of adding rare earth alloy ingot into the furnace and adding ladle, the feeding method of rare earth wire, the hanging method of rare earth metal rod in ingot mold, Spray method, etc., all kinds of methods have their own characteristics, should be fully utilized according to local conditions, in order to obtain the best performance of rare earth steel.
