硼铁矿高炉生产含硼生铁及富硼渣工艺研究

依据冶金物理化学原理，硼铁矿采用高炉生产含硼生铁及富硼渣。含硼生铁是生产硼铸铁、硼钢的合金生铁；富硼渣经缓冷处理为硼化工提供优质原料。该工艺已在１３ｍ￣３高炉上进行两欢工业试验。核工艺流程短、投资少、产量大、能耗低、生产连续化，有价值元素铁和硼得到最有效利用。经济效益和社会效益显著，是开发利用硼铁矿资源切实可行的方案。

PIG IRON CONTAINING BORON AND BORON-RICH SLAG MAD EFROM LUDWIGITE INBLAST FURNACE

Pig iron containing boron and boron-rich slag are made from ludwigite ore in blast furnace based on physical and chemical principle of metallurgy,Pig iron containing boron can be used to produce boron cast iron and boron cast steel; and boron-rich slag after mild cold treatment is the high quality raw material for producing borax and boric acid.The advan tages of this process are as follows:simplified process,less investn1ent,higher production,lower energy consumption as well as more remarkable economic and social benefits.
