化铁炉过铁道(又称过桥或过火道等)是由化铁炉连接到前炉,流过铁水和炉渣的孔道。它虽然在化铁炉结构中占很小的部位,但是在化铁炉与转炉配合炼钢的车间却常常因为化铁炉过铁道发生故障,因而影响转炉的吹炼;严重的甚至影响化铁炉与转炉的平衡作业,所以对过铁道的修砌与维护是很重要的工作。根据我厂生产情况来看,过铁道主要有下面两个问题。一、过铁道里衬耐火材料寿命问题由于熔化的铁水和炉渣全部要通过过铁道进入前
Furnace over the railway (also known as the bridge or overpass, etc.) is the iron furnace connected to the forehearth, through the hot metal and slag channel. Although it occupies a very small part in the structure of the iron furnace, the steelmaking workshop in the iron furnace and the converter often affects the converter’s blowing because of the failure of the iron furnace over the railway. The severe and even damaging effects of the iron The balance of furnace and converter operations, so over the railway repair and maintenance is a very important task. According to our factory production situation, there are two main problems over the railway. First, over the railway lining refractory life issues As the molten iron and slag all through the railway before entering
