我厂每年金加工产生大量铸铁切屑,到处堆放,既影响了厂容,又是一个很大的浪费。七六年感应炉正式投产以后,提出了回收利用铸铁铁屑的任务。铸铁铁屑能否在感应炉内顺利地熔炼,切屑熔液直接浇注的铸件,内在质量能否得到保证?这是生产中急需解决的问题。我们从七七年开始,经过几年来的试验,逐步认识和掌握了切屑熔炼的基
Each year, our factory produces a large amount of cast iron chips and piling up everywhere, which affects the plant capacity and is a great waste. After the induction furnace was put into production in 1976, the task of recycling cast iron scrap was put forward. Cast iron scrap iron can be successfully melted in the induction furnace, the direct casting castings pouring solution, the inherent quality can be guaranteed? This is an urgent need to solve the production problems. We started from 1977, after several years of experiments, and gradually understand and grasp the base of chip melting
