我国不少厂家,尤其是一些中小工厂,用废品率作为衡量铸件的质量指标,这是不全面的。也有一些厂家感到铁水温度高(刚达到1300℃),浇出了普通的灰铁铸件,就满意了。其实,铁水温度高、化学成分符合规定、含气量少、夹杂物低,以及合金元素烧损少等,也都在技术指标的要求之列。本文简要介绍一下国外衡量铁水质量的十个主要指标。 Many manufacturers in our country, especially some small and medium-sized factories, the rejection rate as a measure of the quality of castings, which is not comprehensive. There are also some manufacturers feel hot metal temperature (just reached 1300 ℃), poured out of the ordinary gray iron castings, it satisfied. In fact, hot metal temperature, chemical composition in line with regulations, less gas, inclusions low, and less loss of alloying elements, but also in the technical indicators of the requirements. This article briefly introduces the ten main indicators of foreign hot metal quality.
