出口件实心钢球的铸造工艺

Casting Technology of Export Solid Steel Ball

实心球体热节大,作为出口产品UT检验要求比较高。通过合理设计浇注系统和冒口补缩工艺,使用内冷铁,采用保温冒口等措施,较好的解决了厚大铸件的补缩问题,获得了良好效果。本文介绍工艺设计思路,重点描述如何使冒口和冷铁的配合达到最佳,使该产品既能通过严格的UT检验,又能保持较高的工艺出品率。

The requirements for UT inspection of the solid ball is usually strict as export products due to its large hot spot, the feeding of thick casting has been improved effectively through reasonable design, use of internal chill and insulating risers. The design of the casting technology is introduced, in which the optimum match of risers and chills is described emphatically, thus the products can be approved by the strict UT inspection and obtain higher yielding rate as well.
