中小高炉炉体软水冷却采用的空冷器冷却效果随季节变化而波动,夏天时最高进高炉水温达到70℃以上,影响了高炉的安全高产和使用寿命。板式换热器以波纹板为传热面,传热系数高、体积小、拆装清洗方便,换热强度高,换热效果好,根据中小高炉炉体冷却软水系统流量大、温差小等特点,宜选用316或316L不锈钢材质、结构矮胖型、开二备一、3台并联的板式换热器。济钢2^#355m^3高炉采用BR1.IXC(1.0/100)200.2型水-水板式换热器,软化水进高炉温度全年稳定在34~39℃。 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
