摘要
天钢为降低转炉冶炼成本,对转炉留渣单渣炼钢工艺进行研究。通过理论测算和针对性试验,采用留渣单渣炼钢新工艺后,与原不留渣单渣工艺相比,降低了辅料消耗16.25 kg/t钢,钢铁料消耗降低了3.18 kg/t钢,脱磷率从85%提高到88%。该工艺能够安全可靠地应用于Q235、20等普通钢种的冶炼生产,显著降低了炼钢成本,取得了较好的经济效益。
Tiangang studied converter hot heel and single slag process in order to reduce the melting cost of converter.By means of theoretical measurement and calculation and targeted test,hot heel and single slag new process,compared with single slag process without hot heel,reduced auxiliary material consumption by16.25kg/t tonnage steel and steel material consumption by3.18kg/t tonnage steel and improved dephosphorization rate from the85%to88%.The process could be safely and reliably applied to the melting production of common steel such as Q235and20.Steel-making cost was prominently lowered and good economic benefit obtained.
