我厂自制一台YZ4×5垂直分型无箱射压造型机,从1979年3月投产以来,共生产矿用HZWA型金属支柱的两种小型合格铸钢件达231.2万件,入库量达4113.647t,采用潮型石灰石砂造型,单机生产,用吊夹转移砂型水平串注的工艺,解决了大钢包浇小铸件、原工艺效率低等一系列难题。6年来已发挥了主机高效的作用,实现了半自动
I plant a YZ4 × 5 vertical sub-type box-free shot pressure molding machine, put into operation from March 1979, a total of two kinds of mine production HZWA-type metal pillars of qualified steel up to 2.132 million pieces, the amount of storage Up to 4113.647t. It adopts tide-type limestone sand molding and stand-alone production. It transfers the sand-type horizontal string injection process with the hanging clamp to solve a series of problems such as large ladle pouring small castings and low original process efficiency. 6 years has played a host of efficient role, to achieve a semi-automatic
