宁钢高炉建立了外购原燃料品种质量评价体系,为外购原燃料采购提供技术支撑。在外购焦炭、喷吹煤粉和入炉块矿的评价项目构成中,主要从操作项目和技术项目两方面考虑。开展外购原燃料质量评价后,特别是外购焦质量逐年改善,焦炭灰分从2012年的12.41%降至2015年的12.16%,为高炉炉况稳定、提煤降焦创造了有利条件,有力推动了高炉各项技术经济指标的进步。
The Ningbang blast furnace has established a quality evaluation system for purchased raw material fuels and provided technical support for the purchase of raw materials for purchased raw materials. In the purchased coke, pulverized coal injection and into the furnace ore block evaluation of the composition of the project, mainly from the operation of the project and technical projects from both the consideration. After the quality evaluation of purchased raw materials was carried out, the quality of purchased coke, in particular, was gradually improved year by year. The coke ash decreased from 12.41% in 2012 to 12.16% in 2015, which provided favorable conditions for the stable operation of the blast furnace and the reduction of coke from coal. Promote the blast furnace technical and economic indicators of progress.
