在汽车锻造行业的大量流水生产汽车零件所用的热锻模,过去都是用锻钢加工成型的,不仅加工周期长,寿命短,成本高,而且有可能影响生产任务的完成。近年来,我国有的工厂已开始采用铸造方法生产铸态热锻模,即“陶瓷型精铸锻模”,现将有关情 The hot forging dies used in a large number of water-producing automotive parts in the automotive forging industry have traditionally been formed from forged steels, which not only have long processing cycles, short life, high costs, but also may affect the completion of production tasks. In recent years, some factories in our country have started to use the casting method to produce the as-cast hot-forging die, that is, the “ceramic-type forging die”
