摘要

以钢厂90 t RH精炼过程管线钢37Mn(/%:0.37C、0.21Si、1.44Mn、0.010P、0.003 4S)脱硫优化为目标

在实验室用GL-2型高温管式炉对原工厂用渣系:50CaO-35Al

-7SiO

-8MgO和脱硫剂:75.4CaO-20.1CaF

及优化渣系:57CaO-25Al

-10SiO

-8MgO和脱硫剂:70CaO-30CaF

共17个方案进行管线钢脱硫试验。结果表明

57CaO-25SAl

-10SiO

-8MgO精炼渣系和配合70CaO-30CaF

脱硫剂使用对钢液的脱硫效果最好

并且当渣量为5kg/t

脱硫剂量为0.7 kg/t时

能使钢液中的硫含量降到10×10

Abstract

Aim to optimum-desulfurize the pipeline steel 37Mn (/%: 0. 37C

0. 21 Si

1. 44Mn

0. 010P

0.003 4 S) in 90t RH refining process at steelworks

in laboratory the desulfurization test on the pipeline steel with 17 schemes including original works slag series: 50CaO-35 Al

-7SiO

-8 MgO and desulfurization agent: 75. 4CaO-20. 1CaF2

and optimum slag series: 57CaO-25Al

-10SiO

-8MgO and desulfurization agent: 70CaO-30CaF

has been carried out by a GL-2 type high temperature tubular resistance furnace. Results show that desulfurization effect of 57CaO-25Al

-10SiO

-8MgO refining slag series combined with 70CaO-30CaF

desulfurization agent is best

and as slag amount is 5 kg/t steel combined with desulfurization agent of 0. 7 kg/t steel

the sulfur content in liquid could be decreased to 10 x 10
