天津荣钢转炉干法除尘灰压球应用实践

Application and Practice of Briquetting of Dust from Converter Dry Method Dedusting System at Tianjin Rockcheck Iron & Steel Company

为了加强对含铁固废资源的综合利用,以转炉除尘灰为主要原料,将各种含铁粉尘加入结合剂混合均匀后,利用对辊压球机压制成球,直接返回炼钢转炉使用,降低了炼钢生产成本,提高了冶炼成渣速度,改善了渣料结构,减少了环境污染。

In order to strengthen the comprehensive utilization of resources of ferrous solid waste, all kinds of ferrous dust with converter dust as main raw material, after being added with the binding agent and mixed uniformly, were briquetted into balls by twinroller pressing machine and directly reused in converter. Pro-duction cost at steel-making was reduced. Melting and slagging speed was increased. The structure of raw material for slag was improved. The pollution to the environment was alleviated as well.
