一、绪言近几年来,市场上钢的质量在不断地提高,而且品种也在不断增加。另外,由于社会变动致使近年来的能源条件也变得更加恶化了。根据这种情况,在为改善生产系统使其合理化、降低生产成本和改进一般炼钢工艺的设备及其操作法而进行的许多实验上,由于铁水预处理实用技术,如脱硅、脱磷得到了充分地改善,所以,本研究技术只是起脱碳及无渣精炼工艺的加热作用。本文阐述的是日本神户钢铁公司加古川厂,顶、底吹转炉自从1981年6月采用无渣精炼
First, the introduction In recent years, the quality of steel on the market continues to improve, but also continue to increase varieties. In addition, the energy conditions in recent years have also worsened due to social changes. Under such circumstances, many experiments carried out to improve the production system to rationalize, reduce the production costs and improve the general steelmaking process equipment and methods of operation, due to the practical technology of hot metal pretreatment, such as desilication, dephosphorization Fully improved, therefore, this study only played a decarbonization and slag refining process of heating effect. This article describes the Kakogawa plant in Japan's Kobe Steel, top and bottom blowing converter since June 1981 with non-slag refining
