1982年3月,一项新的精炼工艺——400t鱼雷车铁水脱硅、脱磷、脱硫(SARP——Sumitomo Alkali Refining Process)开始在鹿岛钢厂应用。同年12月在高炉出铁沟进行铁水脱硅处理,新的工艺始臻于完善。 1.工艺概述新工艺的主要特点如下: (1)处理铁水的容量为每鱼雷车300～400t; (2)两种脱硅方法:高炉出铁沟法或鱼雷车法,将根据铁水含硅量和处理数量来选定; (3)向铁水喷吹苏打灰同时脱磷、脱 In March 1982, a new refinery, the 400t torpedo, the desalination, dephosphorization and desulfurization (SARP) process was started at Kashima Steel Works. In December the same year in the blast furnace taphole desiliconization of molten iron, the new process has been perfected. 1. Process Overview The main features of the new process are as follows: (1) The capacity for processing molten iron is 300 ~ 400t per torpedo car; (2) Two kinds of desilication methods: blast furnace trenching method or torpedo car method, Quantity and processing quantity to select; (3) smelting iron smelting while dephosphorization, off
