当我们只是偶尔浇铸一些大型铸件时,炉子的工作是周期性的。(炉衬要冷却到室温)这就使得炉衬寿命特别低,JIT—1炉子的炉衬寿命约为50炉,JIT—2.5炉子炉衬寿命约为30～40炉,而JIT—25炉子的炉衬寿命仅为5～10炉。我们特别需要提高大型炉子JIT—25的炉衬寿命,因为修理感应器,以及随后炉衬打结和烧结,都会导致较长时间的停炉。 在试验期间,我们用下列材料制作炉衬,这些材料是:彼尔沃乌拉尔露天矿的经破碎
When we only occasionally cast some large castings, the work of the furnace is cyclical. (Furnace lining to cool to room temperature) This results in a particularly low furnace life, with furnace lining life of about 50 for the JIT-1 furnace and 30 to 40 for the JIT-2.5 furnace lining, while for the JIT-25 furnace, 5 to 10 furnaces. In particular, we need to increase the lining life of JIT-25 in large furnaces, as repairing the inductor and subsequently lining and sintering of the lining will result in a longer shutdown. During the trial, we made the lining with the following materials: broken pieces of the open pit mine at the Porvoo Ural
