摘要
风力发电机支撑座是典型的小型厚实件,采用树脂砂造型铸造。采用原铸造工艺生产时容易产生氧化夹渣等铸造缺陷。将水平分型水平浇注改进为水平分型垂直浇注的系统,以控制充型线速度,增加单箱浇注重量,结果,有效减少了铸造缺陷的产生,降低了支撑座由于铸造质量问题造成的废品率。
The supporting seat of wind-driven generator is one category of small-scale strong part which is cast by using resinous sand mould.The supporting seats produced by an original casting technology exhibited frequently casting defects such as oxidation and slag inclusion.For this reason,horizontal parting and horizontal pouring were improved into horizontal parting and vertical pouring for the purpose of controlling filling linear speed and increasing weight of single-casting-box pouring.As a result,the casting defects were effectively decreased,and the rejection rates due to faults in casting were reduced for the supporting seats.
