一、铁水质量的控制方法铁水质量的控制首先应该为生产出组织和性能合乎要求的铸件服务。为了尽量能经济而有效地达到这一目的,铁水质量控制首先必须着眼于控制最易发生波动的那些铁水性能(这些性能至今还难于使之保持在狭小的波动范围内),例如:铁水的石墨化倾向及其所产生的各种后果(诸如强度特性和形成缩孔、缩松等方面的巨大波动等);铁水的白口凝 First, the control of hot metal quality control of hot metal quality should first of all be required to produce the organization and performance of casting services. To try to do this economically and effectively, the quality control of hot metal must first focus on controlling the hot metal properties that are most at risk of volatility (these properties have so far not been possible to keep them within a narrow range of fluctuations) such as graphite in hot metal Tendency and its various consequences (such as strength characteristics and the formation of shrinkage, shrinkage and other aspects of the huge fluctuations, etc.);
