Internal chill

Foam mould is used with Tri-box quartz sand air set molding and the quality of pallet is ensured by reasonable design of running and feeding system and placing internal chill in the middle wall-thick position.

通过对托盘结构的分析,设计合理的浇冒系统,采取在中间壁厚部位安放内冷铁等措施,保证了托盘的质量。

Adopting the rational-designed inner chill and analogue simulation verification can ensure that water pipe cann\' t be melt and make directional solidification.

通过对水冷钢砖的结构分析,找出铸造过程中的难点,采用设计合理内冷铁和仿真模拟验证,保证水管不被熔化并形成顺序凝固,采用脱落式芯盒和嵌入式定位,保证螺栓孔、固定栓尺寸位置,采用水玻璃七O砂与铬铁矿砂配合使用,解决螺栓孔难以铸出问题,设计使用专用定位工装,保证各部位尺寸准确,提高铸造质量。
