Smaller slag volume in steelmaking with hot metal containing low silicon will benefit to reduce the consumption of lime and increase metal yield.
低硅铁水炼钢可以实现少渣炼钢，有利于减少石灰消耗和提高金属收得率。
Besides these, lime application improved soil phosphorus nutrition, which was one of the main causes that increased the yield of broad bean.
此外，施用石灰改善了供试土壤的磷营养，磷营养差异是蚕豆产量差异的主要原因之一。
The blowing is smooth and steady, decarbonization and dephosphorization take place simultaneously, the lime consumption is low and the metal yield is higher than that of the top blowing.
吹炼过程平稳，脱碳与脱磷同时进行，石灰用量少，金属收得率较顶吹转炉高。
