摘要
由于对钙处理影响因素的认识不足,不同企业的钙处理效果不尽相同。为了促进钙处理精准度的提升,从钢液和炉渣成分、钙处理合金种类及载体、钙处理工艺操作以及钙处理时机等方面对铝脱氧钢钙处理效果的影响因素及其影响规律进行了简要阐述。钙处理效果影响因素很多,不同企业面临的主要影响因素也不尽相同。研究结果可以帮助钢铁企业认识自身钙处理效果的主要影响因素,进而实现钙处理的精准控制,达到提升产品质量和降低生产成本的目的。
Due to the insufficient understanding of the influencing factors of calcium treatment,the effect of calcium treatment in different enterprises is different.In order to improve the precision of calcium treatment,influencing factors and influencing rules of the effect of calcium treatment of Al-killed steels are briefly described in the current work from the composition of molten steel and slag,the types and carriers of calcium alloys,the operation of calcium treatment process and the timing of calcium treatment.Many factors are affecting the effect of calcium treatment,and the main factors different enterprises facing are also different.The results can help steel enterprises to understand the main influencing factors of their calcium treatment operation,and then realize the precise control of calcium treatment,which improves the product quality and reduces the production costs.
