一、浇注方法的选择随着铸造生产的发展,砂型铸造浇注机械化与自动化也有了新的进展。实行机械化浇注可以提高生产率,减少废品,节省铁水,节约人力,改善环境。因此,人们对了解有关这一方面情况的兴趣越来越浓厚。进行正确的浇注是提高铸件质量的关键,铸造工艺不同,其合适的浇注速度也就不同。浇注不精确或浇注过程间断,都将会导致铸件 First, the choice of casting method With the development of casting production, sand cast casting mechanization and automation has also made new progress. The implementation of mechanized pouring can improve productivity, reduce waste, save hot metal, save manpower and improve the environment. As a result, there is growing interest in learning more about the situation in this area. Proper casting is to improve the quality of the casting key, casting process is different from the appropriate casting speed will be different. Inaccurate casting or intermittent casting process will result in casting
