一、配合参数应用多台炉冶炼浇注大铸件,首先要正确拟定配合参数,找出主、次矛盾。经周密考虑和对失败的分析研究,确认开浇温度、钢水在包内的镇静时间、浇口砖内径和出钢温度四个参数为其配合参数,并以前两者为主要参数。 1.开浇温度联合浇注大铸件的开浇温度的合理选择,不仅关系到铸件的质量,而且直接影响着浇注的成功与失败。根据资料介绍,开浇温度一般应接近钢的熔点或比熔点高20~30℃,对于45°钢
First, with the application of multiple furnace casting pouring large castings, we must first correctly formulated with the parameters to identify the main contradictions. After careful consideration and analysis of failure, it is confirmed that pouring pouring temperature, pouring time of molten steel in pack, pouring brick inner diameter and taping temperature are the four parameters, and the former two are the main parameters. 1. Open pouring temperature pouring large casting pouring temperature of a reasonable choice, not only relates to the quality of the castings, but also directly affects the success and failure of pouring. According to the information, open pouring temperature should generally be close to the melting point of steel or higher than the melting point 20 ~ 30 ℃, 45 ° steel
