转炉生产弹簧钢的工艺研究
TECHNOLOOGICAL STUDY ON PRODUCTION OF SPRING STEEL BY CONVERTER
-
摘要: 本试验旨在研究开发转炉冶炼60Si2Mn弹簧钢的生产工艺。通过试验确定了合理的脱氧、合金化等工艺,保证了钢质纯净,钢材非金属夹杂物总和 ≤ 3.5级。所制成的汽车钢板弹簧抗疲劳性能优良,产品综合性能完全达到同类电炉钢的水平。Abstract: This test has been conducted for the purpose of development of production technology of 60Si2Mn spring steel by converter。The rational deoxidation and alloying process are determined to obtain clean steel and keep total non-metallic inclusions≤3.5 grade,The fatigue resistant property of the trial automobile sheet spring is excellent.The combined properties of the steel are equal to those of the electric furnace steel.
