高碳铬铁除尘灰压球可行性研究

FEASIBILITY STUDY ON COLD-PRESSURE BALL PROJECT OF HIGH CARBON FERROCHROME DUST

分析了高碳铬铁除尘灰的性能,并研究了高碳铬铁除尘灰冷压成球的生产工艺,同时利用铬系铁合金除尘烟气余热烘干高碳铬铁除尘灰压球的新工艺,估算建设12 000 t/a高碳铬铁除尘灰压球生产工艺投资、成本和经济效益,该项目实现了高碳铬铁除尘灰回炉再冶炼,变废为宝,实现了资源循环再利用,可产生一定的经济效益和环境效益,是值得高碳铬铁铁合金企业开发的项目。

This paper analyzes the performance of high carbon ferrochrome dust,and studies the production technology of cold-pressing ball with high carbon ferrochrome dust. The paper computes the investment cost and economic benefits for building a line of production process to cold-press 12 000 t/a HC-ferrochrome dust accoring to the new technology. The project makes the high carbon ferrochrome dust re-smelting,turns the waste valuable,realizes resource recycling. It produces a certain economic and environmental benefits. It is a project worth developing for high carbon ferrochrome ferroalloy enterprises.
