属于国内首创的转炉钢渣粒化处理工艺已由包头钢铁研究设计总院研发成功,并在包钢薄板厂210t转炉上热试车成功。转炉钢渣粒化处理工艺采用机械破碎与水淬相结合的办法.熔渣被高速旋转的粒化轮碎成小颗粒.然后被高压水冷却、水淬而成为产品。该工艺对渣中残钢回收率达98%以上,可回收残钢量为钢总量的3.43%~3.92%, 相似文献

转炉钢渣的综合利用是实现钢铁联合企业固体废弃物零排放的关键环节,而通过对转炉钢渣进行粒化,配加在烧结生产中可以更好实现钢渣的无害化处理。就粒化钢渣的特性,在烧结生产中配加粒化钢渣进行了工业生产实践,结果表明:在不同烧结原料结构下配加粒化钢渣,对烧结矿的质量影响差距较大,但总体表现是对烧结矿指标有所改善,特别是在全精料原料结构下,在保证烧结矿硅质量分数需要的同时,能够替代部分烧结熔剂,起到降本增效的目的。 相似文献

In present,the wet-based pattern is mainly adopted to deal with the steel slag by steel plant at home and abroad,the wet-based technology has some defects;Wasting of water,pollution of the environment,and the slag has not been fully recycled.This paper presents a new method,which is aimed to realize dry granulation,waste heat recovery and comprehensive utilizing the steel slag.According to the ideas of wind quenching granulation,the heating slag from the converter furnace,was bring to the granulation heat exchange system,through the process of breaking in a container,the granulation heat exchange system has the functions of feeding continuously and heat exchange.The heat air,through the diversion tubes,could be recycled in removing the dust.The granulation slag could be bring to a confined roller,granulating and cooling secondarily.The roller export was connected to a magnetic separator.The separated iron could be recycled,and the remaining slag could also be reused as building materials,in process of stabilization and secondary magnetic separation.The heated air could be guided into the boiler to generate the steam,which can be used to generate electricity,or use as cleaned energy,realizing the target to recycle the waste heat in steel slag.The highlights of the new method are dry granulation and waste heat recovery.This paper states the process of heat exchange between the air and the steel slag in the system of granulation heat exchange in the new technical process.In theory,it has been proved reasonable with the the system of granulation heat exchange,and also the work conditions has been optimized. 相似文献
