一种提高含硅钢表面质量的方法
摘要：
本发明具体涉及一种提高含硅钢表面质量的方法。其技术方案是：将含硅钢以23~25℃/min的升温速率升温至500~800℃，再以3~6℃/min的升温速率升温至1180~1260℃，保温20~40min，然后空冷至室温。所述含硅钢的化学成分及其含量是：C为0.070~0.084wt%，Si为1.20~1.60wt%，Mn为1.10~1.94wt%，Cr为0.010~0.020wt%，P≤0.016wt%，S≤0.005wt%，Ni≤0.008wt%，其余为Fe及不可避免的杂质。本发明具有工艺简单、适用于工业生产、能有效减少红色氧化铁皮的特点，有效地提高了含硅钢表面质量。
摘要（英）：

The invention particularly relates a method for improving the surface quality of silicon-containing steel. According to the technical scheme, the method is characterized in that the silicon-containing steel is heated to the temperature of 500 DEG C-800 DEG C at the heating rate of 23 DEG C/min-25 DEG C/min and then heated to the temperature of 1,180 DEG C-1,260 DEG C at the heating rate of 3 DEG C/min-6 DEG C/min, the temperature is kept for 20 minutes to 40 minutes, and then air cooling is performed to the room temperature. The silicon-containing steel comprises 0.070-0.084 wt% of C, 1.20-1.60 wt% of Si, 1.10-1.94 wt% of Mn, 0.010-0.020 wt% of Cr, not larger than 0.016 wt% of P, not larger than 0.005 wt% of S, not larger than 0.008 wt% of Ni and the balance Fe and inevitable impurities. The method has the beneficial effects of being simple in process, suitable for industrial production and capable of effectively reducing red scale and effectively improving the surface quality of the silicon-containing steel.
