由于钢铁工业的飞跃发展,使铁合金的供应紧张起来,这需要一方面贯彻土洋结合的方针,大力增产铁合金,一方面应当力求在各方面节约铁合金的使用。以下就冶金部召集的节约铁合金研究小组讨论过的几个问题及作者的一些意见作一简单叙述以供参考。一、转炉设计及操作中如何节约用铝及矽铁的问题1.转炉在设计中选择鼓风机型号其风量及风压必须配合适当,风量过少会延长吹炼时间,增加钢水热的损失,根据目前国内所采用的转炉其风量及风压应 Due to the rapid development of the iron and steel industry, the supply of ferroalloy is tense. This requires implementing the principle of combining the soil and the earth and vigorously increasing ferroalloy production. On one hand, efforts should be made to save ferroalloy in all aspects. Here are some of the issues discussed by the Metallurgical Department convened by the conservation of ferroalloy research group and some of the author’s comments for a brief account for reference. First, the converter design and operation of how to save the problem of aluminum and ferrosilicon 1 converter in the design of the blower model its air volume and air pressure must be appropriate, too little air volume will extend the blowing time to increase the heat loss of molten steel, According to the current domestic use of the converter air volume and wind pressure should be
