碳当量在3.6～3.9范围内不同Si/C比对铸件组织和性能的影响

The Influence of Different Si/C Scales on Casting of Carbon Equivalent Between 3.6～3.9

以陕西压延设备厂生产的HT2 5 0以上的铸铁件为依据 ,通过 1998年 10月份前后大量数据的类比分析方法 ,寻找不同的Si/C比与机械性能、金相组织之间的关系 ,并严格控制熔炼工艺 ,提出了一些解决的措施 。

In terms of the HT250 series products which are made in Shanxi Stretch Equipment Factory, experimental data have been investigated by the application of such mathematical methods in order to determine the relation among different Si/C scales, mechanical behavior and metallographic organization. With reference to the relation, a strict control of the smelting technology is taken. Some methods are put forward to solve these problems. Substantial benefits are produced after these measures are taken.
