摘要
综述了20CrMnTi钢Ti含量控制和钢包喂Ti线技术,分析了钛在钢中的作用机理、钢包喂钛线的影响因素,设计出首钢精炼钢包喂Ti线合金化工艺,经工业试验证明:该工艺生产的20CrMnTi钢各项力学性能满足国标要求,提高收得率10%,降低了生产成本,取得了良好效果。
The development of wire-feeding technology and the controlling technology of Ti content in 20CrMnTi steel is outlined. The mechanism of Ti in steel and factors of Ti wire-feeding are analyzed.The Ti wire-feeding alloying process of refining ladle in Shougang Group is designed. The experimental result shows the mechnical properties of 20CrMnTi steel can meet the demands of national standard, the xenolith rate of Ti rises by 10% and the production cost is reduced.
