钢球磨床齿圈的工艺改进

The improvement on technology of gear whell of steel-ball-grinder

根据球墨铸铁球化时石墨化膨胀原理 ,利用暗冒口使球化膨胀只能在型内膨胀 ,从而形成组织致密的铸件 ;同时 ,改一箱单件生产为一箱多件生产 ,从而大大提高了生产效率。

By expand principle of graphitization and using inner riser,the expund of ballizer is carried out in the model and cast of fine and close intexture form.By alternating produce of single box into produce of many boxse,the efficiency of produce are raised.
