采用ZG270-500和高铬铸铁分别作为锤柄和端部材料生产铸镶锤头。在强度足够的前提下尽量减小锤柄结合部位体积。采用侧冒口补缩,金属液流经冒口进入型腔,减小冒口及冒口颈尺寸,提高工艺出品率。锤头使用寿命是同等工况下高锰钢锤头的3倍以上。
ZG270-500 and high-chrome cast iron were used as the hammer handle and the end of the production of cast iron hammer. Under the premise of strength enough to minimize the hammer handle the volume of the binding site. The use of side riser uplift, metal flow through the riser into the cavity, reducing riser and riser neck size, improve process yield. Hammer life is the same high manganese steel hammer more than 3 times.
