以煤代焦　提高喷煤比

Replacing Coal by Coke and Increasing Injection Coal Ratio

钢铁企业在具备一定的生产规模的基础后，发展方向应及时地转变到优化生产结构、降低成本增效益上来。炼铁工艺应以提高喷煤比作为主要措施之一，从经济增长方式根本转变的高度，提高认识，加大投资力度，改造和完善喷煤设施，提高喷煤比。

When metallurgical industrial enterprise has possessed a certain producing scale its developing trend must be to turn towards optimizing product structure,decreasing production cost and increasing economic result As far as ironmaking industry is concerned,increasing injection coal ratio is a main measure for coming up to above mentioned aim through reforming and improving injection coal equipments
