摘要
攀成钢公司采用“80吨转炉冶炼→LF精炼→150方坯连铸→Φ500轧机轧圆钢”工艺生产小规格管坯钢。通过对转炉终点控制、LF炉造渣优化1、50方坯连铸二冷曲线的研究实践,证明使用150方坯连铸机生产的小规格管坯钢工艺稳定、质量可靠。
In Pangang Group Chengdu Iron & Steel Co.,Ltd.,small sized steel blooms for tube-rolling purpose are produced with the manufacturing process of steel melting with 80t converter →LF refining →continuous casting of 150 square billet →producing round bloom with Φ500 rolling mill.Thanks to measures as taken such as proper end-point control of the converter process,optimization of LF slag forming and study and application of the secondary cooling curve of the 150 square billet C.C.machine,the said manufacturing process is not only consistent itself, but also capable of producing blooms with consistent quality.
