作为单一生产铸造铁的中小企业,都存在着共同的问题:由于浇铸成块时的小铁损失率一般在5％左右,这就给高炉生产带来无止境的循环,生产越多,损失也越大。 1984年以来,我厂先后对链带式铸铁机喷浆及附属系统进行了技术改造,使小铁率由6％降到3％左右。但是,由于铸铁模块之间存有间隙,浇铸时满模飞溅的小铁仍有2％左右。这部分小铁怎么利用,一直是难以解决的问题。但也没有引起人们的特别重视。 As a single production of small and medium-sized iron casting, there is a common problem: due to the casting of small pieces of iron loss rate is generally about 5%, which gives the blast furnace production endless loop, the more the production, the loss is also The bigger Since 1984, our factory has carried out technological transformation to the shot blasting of the belt cast iron machine and the affiliated system so that the small iron rate will be reduced from 6% to about 3%. However, due to the gap between the cast iron modules, there is still about 2% of the small iron splashed during casting. How to use this part of the iron has always been a problem that can not be solved. But it did not arouse people’s special attention.
