摘　　要：转炉煤气经干法除尘后产生的除尘灰主要成分为Fe和Ca及少量固体C，具有粒度细、含铁量高的特点，是可回收的二次资源。通过对除尘灰进行原料分析、配料计算、采用冷固球团生产工艺，生产出符合首钢京唐钢铁厂转炉使用要求的冷固球团。经炼钢厂现场使用证明其具有较好的冷却和化渣效果。按吨钢消耗20kg冷固球团计算，每年可回用转炉除尘灰18．55万t，相当于每年可节约澳矿或球团矿17—18万t，降低了外购含铁资源的费用，经济效益和社会效益显著，符合循环经济模式。The dust ash is produced by dry process of conveter gas, its main components is Fe and Ca, and some solid carbon, has the character of fine granularity and high iron content. Through material analyse and mixture calculation, it can produce cold solid pellets by cold solid pellt process. The field use in steel mills show that it has good cooling and the residue effect. It can reduce 185,500 tons dust ore per year, e- quals to 170, 000 - 180, 000 tons Australian ore or pellets. Acccording to that, it can greatly reduce the outsourcing iron resources costs, economic benefit and social benefit is remarkable, conform to the circular economy mode.
