柴油机飞轮铸造生产工艺

Casting Technology of Diesel Engine Flywheel

针对飞轮铸件厚大的特点及容易出现的缺陷,采用计算机模拟改进了浇注系统、冷铁加快厚大部位冷却、横浇道作为补缩冒口,以旋转集渣包进行集渣,横浇道实现挡渣等铸造工艺措施。结果表明,采用电炉熔炼,结合喂丝球化,成功生产出1.3 t的飞轮产品。

In view of the characteristics of large thickness of flywheel castings and the defects that were easy to appear,computer simulation was adopted to improve the casting process,such as the gating system,the chiller to accelerate the thickness of most of the cooling,the runner as feeding riser,the rotating slag collecting bag to collect slag,and the runner to prevent slag.The results show that 1.3 t flywheel products are successfully produced by electric furnace melting and wire feeding spheroidizing.
