引言铸铁的熔炼是铸造生产的首要环节,也是决定铸件质量的一项根本因素。承担铸铁熔炼的冲天炉不仅仅是把固体生铁等转变成相同化学成份铁水的装置,而且还应该完成把低级炉料转变为合格铸铁的冶金过程。要实现这种冶金过程,要求炉内不但有高温的炉气;而且炉气还应是较强还原性气氛。冷风冲天炉炉气温度最高伪1600～1700℃,而
Introduction Cast iron smelting is the primary link in the production of castings and also a fundamental factor in determining the quality of castings. Cupola, which takes on smelting cast iron, is not just a device that converts solid pig iron and the like into hot metal of the same chemical composition, but also completes the metallurgical process of converting low-grade charge material into qualified cast iron. To achieve this metallurgical process, the furnace requires not only high temperature furnace gas; and furnace gas should also be a strong reducing atmosphere. Cold blast furnace furnace temperature of the highest pseudo-1600 ~ 1700 ℃, and
