Abstract
Traditional high chromium cast iron is cast by gravity casting,but this method often suffers from casting defects and model cracking.Therefore,a liquid forging method is proposed in this study.By designing the mold and analyzing the process parameters during liquid forging,the goal is to optimize the process and improve the performance of the mold.Simultaneously researching the use of heat treatment to enhance the actual performance of molten metal.The research results show that the hardness of the metal reaches 56.8HRC at a temperature of 530℃ after heat treatment,and the hardness of the metal increases by 7.1HRC.The impact toughness of high chromium cast iron metal can reach up to 24.8J/cm2.It can be seen that high chromium cast iron after heat treatment can effectively improve metal properties,and the mold performance after process optimization is also effectively improved.This has good guiding significance for optimizing the liquid forging process of high chromium cast iron and improving the performance of forging molds.关键词
