钢液浇注的充型方式是影响轧机机架等大型铸钢件质量的关键因素。通过分析国内外轧机机架浇注的充型方式,指出充型方式的选择应该结合浇注速度,并对浇注过程中铸件温度梯度进行合理控制。针对马钢重机公司现有低速浇注的不利生产条件,选择了阶梯浇注的钢液充型方式,铸造出高品质的轧机机架,得到国内外用户的认可和好评。 Molten filling method is the impact of rolling mill and other large steel castings quality key factors. By analyzing the filling and pouring methods of rolling stands at home and abroad, it is pointed out that the choice of filling mode should be combined with the pouring speed and the casting temperature gradient should be controlled reasonably. In view of the unfavorable production conditions of the existing low-speed casting of Masteel Heavy Machinery Company, a step-filling molten steel filling mode was selected to cast a high-quality rolling stand and was approved and praised by users at home and abroad.
