铸铁铁屑经锻、冲设备压实后,可代替回炉铁直接投炉熔化浇注成铸件,已在我厂铸工车间试验成功。经初步投产使用证明,效果良好,对解决当前铸铁供不应需起一定作用。一、铁屑冷压成块 1.铁屑准备:用洁净而不混入其他金属屑的铁屑。为了取得较好的代铁效果,不准加入想像会增加铁屑块强度的石灰、卤水等物,否则,将会使铁屑氧化,影响代铁效果。 2.压实操作:铁屑的冷压是在400公斤空气锤上进行的,模具结构如图1。操作时,升起冲头,垫砧送进成型模底,把铁屑装入成型模内(图2)。开锤将铁屑打实后,冲头升起,垫砧拉回原处(图3),落下冲头,被打实的 Cast iron scrap by forging, pressing equipment, compaction, instead of directly cast iron melting furnace cast iron casting, casting plant in our plant has been successfully tested. The initial commissioning of the use of proof that the effect is good, to solve the current cast iron supply should not play a role. First, the cold pressed into pieces 1. Iron scrap preparation: with clean and not mixed with other metal scrap iron. In order to achieve a better generation of iron, it is forbidden to add lime, brine and other objects that would increase the strength of the iron filings. Otherwise, iron filings will be oxidized and the iron generation effect will be affected. 2. Compaction operation: cold iron scrap is carried out on a 400 kg air hammer, mold structure shown in Figure 1. Operation, raise the punch, anvil anvil into the mold base, the iron filings into the mold (Figure 2). Hammer hammer iron hit later, the punch raised, pad anvil pulled back to the original place (Figure 3), the punch down, was hit
