概述铸铁件的内在质量决定于三个主要因素:浇注系统,铁水质量,型砂质量。这些因素又互相联系。浇注系统的合理设计在一定程度上可以改善型砂,铁水质量方面的不良影响。但是,决不能因此放松对型砂、铁水质量的控制,而单纯只考虑浇注系统的改进,必将造成浇注系统的结构复杂,体积庞大,操作麻烦。因此,影响铸件质量的因素,都应全面考虑。另一方面,在生产实际中,铁水的温度和成
Overview The inherent quality of castings depends on three main factors: the pouring system, the quality of the molten iron, the quality of the molding sand. These factors are related to each other. The reasonable design of the pouring system to a certain extent, can improve the sand, hot metal quality adverse effects. However, the quality of molding sand and molten iron must not be relaxed. Therefore, simply considering the improvement of the pouring system will surely cause the structure of the pouring system to be complex, bulky and troublesome to operate. Therefore, the factors that affect the quality of castings should be fully considered. On the other hand, in the actual production, the temperature and temperature of molten iron
