【摘要】 研究了含碲铁料的重熔特性和回用效果。试验表明:重熔不能消除残余碲的有害影响。含碲炉料可用于生产含碲灰铸铁和冷硬抗磨铸铁。加入微量·1稀土合金能明显降低碲的负作用,并提高铸铁的机械性能。更多还原

【Abstract】 The feature of remelting of iron returns containing tellurium were investigated.Experiments showed that it is impossible to eliminate the harmful effect of residual tellurium in the iron returns by their remelting.Te containing returns can be used in producing Te containing gray iron and chilled wear resistant iron.A little addition of RE-Si-Fe alloy decreased obviously the effect of tellurium, and increased mechanical properties of cast iron.更多还原
