摘要

泰山不锈钢厂采用60 t电弧炉-GOR底吹转炉精炼-160 mm×1600 mm板坯连铸的工艺流程冶炼不锈钢。通过Gleeble-1500D热模拟试验机试验研究了奥氏体不锈钢201(6.54Mn-16.71Cr-3.62Ni)和J4(8.93Mn-14.84Cr-1.08Ni-1.25Cu)

铁素体不锈钢430(16.29Cr)和马氏体不锈钢410S(13.5Cr)连铸板坯的高温力学性能。结果表明

各不锈钢的第Ⅲ脆性温度区分别为201钢-665~990℃

J4钢-600~950℃

430钢-600~700℃和410S钢-720~930℃;201和J4钢采用较弱二次冷却

矫直温度分别控制为≥1010℃和≥995℃

430钢用较强二次冷却

矫直温度900~950℃;410S钢用较弱二次冷却

矫直温度≥980℃。

Abstract

The production flow sheet for stainless steels steelmaking at Taishan Steel Works is 60 t EAF-GOR bottom blowing converter refining-160 mm x 1600 mm slab casting process. With using Gleeble-1500D thermal simulation testing machine

the high temperature properties of casting slab of austenite stainless steel 201 ( 6.54Mn-16.71Cr-3.62Ni) and steel J4 (8.93Mn-14.84Cr-l.08Ni-l.25Cu)

ferrite stainless steel 430 ( 16.29Cr) and martensite stainless steel 410S (13.5Cr) have been tested and studied. Results show that the Ⅲ brittle temperature region of each stainless steel is respectively steel 201-665 ~990 ℃，steel J4- 600~950 ℃ steel 430- 600~700 ℃ and steel 410S-720~930 ℃ ； It is available for steel 201 and J4 to use weaker secondary cooling and to straighten respectively at ≥1010 ℃ and ≥995 ℃

for steel 430 to use stronger secondary cooling and to straighten at 900~950 °C

and for steel 410S to use weaker secondary cooling and to straighten at ≥ 980 °C.
