一种短流程生产低碳低硅含铝钢的生产方法
摘要：
本发明属于冶金工艺领域，具体涉及一种短流程低碳低硅含铝钢的生产方法，各组分的重量百分比为，C:0.04％～ 0.06％，Si:0 ～0.03％，Mn:0.15％～ 0.25％，P:0 ～ 0.02％，S:0 ～ 0.015％，Als：0.015％～ 0.050％，余量为Fe及不可避免的杂质，本发明减少LF环节，在不影响钢水纯净度的情况下杜绝了因LF工艺处理造还原渣导致的回硅问题，从而提高低碳低硅含铝钢中Si 含量的达标率，提高产品成品率，通过在CAS站强脱氧，使钢水短时间内脱氧完全，提高了钢水可浇性，减少了水口絮流，实现大批量稳定化连铸生产低碳低硅含铝钢。
摘要（英）：

The invention belongs to the field of metallurgy processes and particularly relates to a p roduction method for producing low-carbon low-silicon and aluminum-containing steel through a short process. The low-carbon low-silicon and aluminum-containing steel is composed of, by weight, 0.04-0.06% of C, 0-0.03% of Si, 0.15-0.25% of Mn, 0-0.02% of P, 0-0.015% of S, 0.015%-0.050% of Als and the balance Fe and inevitable impurities. An LF link is omitted, the problem of silicon reversion caused by LF process treatment for reducing slag is solved under the condition that the purity of molten steel is not influenced, so that the target rate of Si content in the low-carbon low-silicon and aluminum-containing steel is increased, and the product yield is increased; and through CAS station strong deoxidation, the molten steel is completely deoxidized in short time, the molten steel castability is improved, sprue flocculating flow is reduced, and mass stable continuous casting production of the low-carbon low-silicon and aluminum-containing steel is achieved.
