Because the metal melt fluid washes outthe furnace lining unceasingly as the metallurgy smelting, the different furnace lining material, the furnace lining smelting life is dissimilar, so power frequency furnace is also same as any other type smelting when they are manufactured, not equiping with furnace lining material, the using factoryshould have the professional furnace lining technical personnel and furnaceman.

由于冶金熔炼时，金属熔液不断冲刷炉衬，不同的炉衬材料，炉衬熔炼寿命也不一样，不同的金属所适应的炉衬材料也不一样，所以工频炉出厂也同任何种类熔炼出厂一样，不配备炉衬材料，使用厂应备有专职的炉衬技术人员和筑炉工。

Because time metallurgy smelting, the metal melt fluid washes out the furnace lining unceasingly, the different furnace lining material, the furnace lining smelting life is dissimilar, the different metal adapts the furnace lining material is dissimilar, therefore power frequency stove leaving the plant is also same as any type smelting leaving the plant, does not provide the furnace lining material, the use factory should have the professional furnace lining technical personnel and build the furnaceman.
