针对壁薄、面积大、表面不加工的平板铸造易出现弯曲变形、表面质量不好等问题,采用平做立浇、组型串铸、中部敝开、砂型表面用钢板紧固的铸造工艺,能有效控制大平板薄壁铸件发生弯曲变形,并可以提高铸件表面质量。
For the wall thin, large area, the surface is not flat plate casting prone to bending deformation, the surface quality is not good and so on, the use of flat to do the pouring, group type string casting, the central open, the sand surface with steel fastening casting process, Can effectively control the deformation of large-wall thin-walled castings, and can improve the casting surface quality.
