铸造生产中一个最普遍的问题:就是在保证铸件质量的情况下,如何提高经济效益,即如何提高工艺出品率。广大铸造工作者和工程技术人员一直在对这个问题进行研究。在轧辊铸造上,开始时,辊身和辊颈一样粗细,甚至个别厂家的冒口比辊身还要粗,至今还有少数厂家保留着这一工艺。这样工艺出品率就低,同时给加工带来很大困难,而且对金属材料有很大
One of the most common problems in foundry production is how to improve the economic efficiency under the circumstance of guaranteeing the quality of castings, that is, how to improve the production rate of technology. The majority of foundry workers and engineering and technical personnel have been studying this issue. In the roll casting, the beginning, the roll body and roll neck as thick, and even individual risers than the roll still rough, so far there are a few manufacturers to retain this process. This process yield is low, at the same time bring great difficulties to the processing, but also for the metal material is very large
