摘要
在铸造工艺技术人员的传统设计理念中,普遍认为在保证铸件质量的前提下,应用的浇口杯容积越大其所耗费的金属液就越多,金属液的有效利用率就会越低;同时,浇口杯容积越大,相应的浇注时间就会越长,生产效率便会越低,经济性也就越差。本文主要以逆向思维的方式,针对常用浇口杯铸型中金属液利用率和生产效率低的问题,采用MAGMA软件对大浇口杯铸造工艺进行充型和凝固等过程的模拟,对常用浇口杯和大浇口杯铸造工艺进行了对比分析。结果表明,采用大浇口杯能够显著提高DISA铸造生产线的生产效率,单位时间内的造型和浇注效率得到显著提升,在铸造企业具有很高的推广价值。
In the traditional design concept of foundry technologists,it is generally believed that under the premise of ensuring the quality of castings,the larger the volume of the pouring cup applied,the more metal liquid it consumes,and the lower the effective utilization rate of metal liquid.Meanwhile,the corresponding pouring time is prolonged with increasing volume of the pouring cup,resulting in low production efficiency and poor economic efficiency.However,this paper mainly studies the related process technology in reverse thinking.In view of the low utilization rate and production efficiency of molten metal using a common pouring cup,simulations of the filling and solidification processes of both the common pouring cup and the bigger pouring cup were conducted using MAGMA software,and then comparative research was carried out.The results show that using a bigger pouring cup can significantly improve the production efficiency of DISA casting production lines,with prominent improvement in the efficiency of molding and pouring per unit time,which proves that it has high promotion value in casting enterprises.
