在电炉生产工艺条件下,把钢中[S]控制到0.010%以下是相当困难的,脱硫成为生产低硫管坯钢的一大技术难题,而LF直流电弧—电渣加热钢包炉解决了快速脱硫的技术难题。本文详细介绍安钢电炉+LF直流电弧—电渣加热钢包炉生产低硫管坯钢的生产经验。
It is quite difficult to control [S] below 0.010% in steel under the conditions of electric furnace production. Desulfurization has become a major technical problem in the production of low-sulfur tube steel. LF direct current arc-electric slag heating ladle furnace solved the problem of rapid Desulfurization of the technical problems. This article details the production experience of Anyang EAF + LF DC arc-ESR ladle furnace for producing low-sulfur tube steel.
