目前国内重型水压机车间在锻造前加热钢锭所采用的炉型绝大多数是台车式加热炉。这种炉型属间隙式交温炉,炉膛内不分区段,炉温按规定的加热制度随时间而变化,其结构特点是钢锭加热前后可将台车炉底牵引出炉膛进行装卸,加热工件的形状比较通用、灵活。但这种炉型热效率较低,损耗大。而重型水压机车间内,这类加热炉数量又多,因此在机电行业中是能量损耗大户。这一问题已普遍引起各 At present, the heavy-duty hydraulic press shop in the forging of the ingot before the furnace used in the vast majority of car-type furnace. This type of furnace is a gap type temperature furnace, the furnace is not divided into sections, the furnace temperature according to the provisions of the heating system changes over time, the structural features of the steel ingot can be heated before and after pulling the furnace bottom loading and unloading, heating the workpiece The shape is more general and flexible. However, this type of furnace thermal efficiency is low, loss. The heavy hydraulic press workshop, the number of such furnaces and more, so in the electrical and mechanical industries is a major energy loss. This issue has generally caused all
