WJ911252 坩埚感应炉铸铁无废料熔炼用团块——1990,№4,26, (俄) 本文介绍了苏联哈尔科大理工学院研究的团块炉料熔炼铸铁新方法。由于在机械行业中大量金属料被白白浪费掉了,利用这些黑色金属废料作为坩埚感应炉炉料有利于降低炉料成本。作者介绍了团块制作工艺及化学成分,即以废料为主,添加一定数量的萤石和工业机质素磺酸盐固体沉积水溶液制成的团块,不仅具有高还原能力,低的热加工温度和高的强度,而且,由于采用木质素磺酸盐作为还原剂和粘结剂,使团块成本较低。
WJ911252 Crucible induction furnace cast iron scrap without waste melting block - 1990, №4,26, (Russia) This article describes a new method of agglomeration of cast iron castings studied by the Harbin Institute of Technology Dali. As a large number of metal materials in the machinery industry was wasted, the use of these black metal scrap crucible induction furnace charge will help reduce the cost of charge. The author introduced the production process and chemical composition of clumps, that is to waste, adding a certain amount of fluorite and industrial organic matter sulfonate solid deposition aqueous solution made of clumps, not only has high reducing power, low thermal processing temperature And high strength, and, due to the use of lignosulphonates as reducing agent and binder, the lumps cost less.
