摘要: 采用55t 转炉+60t 钢包精炼炉,150mm×150mm4 流弧形连铸机,短应力连轧机组生产425 mm 非调质钢 F40MnV(%:0.39~0.43C,1.20-1.36Mn,0.07~0.10V,0.009~0.024P,0.011~0.018S)。钢中氧 含量[0]为(18.8-20.5)×10-6,[N]为(35.2~53.2)×10-6。钢的化学成分、力学性能、纯洁度、高低倍组织均 达到标准和用户要求。为控制钢中N 含量可选择加 VN 合金,在微合金化时增氮。

Abstract: The φ25 mm bar of microalloying stocl F40MnV- 0.39~0.43C,1.20- 1.36Mn,0.07~0. 10V 0.009~0.024P,0.011~0.018S was produced by a 55 t converter + 60 t ladle refining fumace,150 mm×150 mm 4 strand concaster, short- stressed continuous rolling mill strain process. Okygen content in steel [0] was(18,8~20.5)x 10-6 and[N] was(35.2~53.2)×10-6,The chemical compositions, mechanical properties, cleanliness and micro- ant macrostructure of steel are all up to the requirement of standard and the demand of customers, VN alloy shall be selecter adding during microalloying of steel to increase the nitrogen content
