Holding time also has a little of effect on initial precipitation temperature of all kinds of phases in the Al-Si alloy, the solidification caloric value changes from small to big and then to small as the holding time extends.
保温时间对Al-Si合金内各相初始凝固温度的影响也很小,而凝固焓变值随保温时间的延长经历了由小变大再变小的过程。
It provide a scientific basis for the electrode melting velocity control and the temperature control of the ingot solidification process, and have a certain value for the actual production.
本文采用的研究方法为目前国内铸造行业研究的热点,为电极熔速的控制和钢锭凝固过程温度控制、结晶器设计等提供了科学依据,对实际生产工程有一定的应用价值。
