ZJ001型真空吸铸机由一机部铸缎机械研究所投计由青岛生建机械厂试制,于1965年12月完成并经鉴定合格。真空吸铸是一项先进的铸造技术,具有铸件质量好、生产效率高、劳动条件好等优点。用其空吸蕴法镌出的工件与一般砂型铸造比较有下述之优点: 1.蟋件无缩松、斜孔、气孔、砂眼等铸造缺陷。金相组织细密,晶粒细小; 2.铸件机械性能显著提高; 3.生产效率高,每小时可达40件左右; 4.铸件表面光洁,减少加工刀具磨损; 5.改善劳动条件。
ZJ001-type vacuum suction casting machine by a Department of Machinery Research Institute invested by Qingdao Shengjian Machinery Factory trial production, in December 1965 completed and identified by qualified. Vacuum suction is an advanced casting technology, with casting quality, production efficiency, good working conditions and so on. Compared with the common sand casting, the workpiece engraved with its suction suction method has the following advantages: 1. The cricket has no shrinkage, slanting holes, pores, trachoma and other casting defects. Metallurgical microstructure, small grains; 2. Castings significantly improve the mechanical properties; 3. High production efficiency, up to 40 per hour or so; 4. Casting surface smooth and reduce processing tool wear; 5. Improve working conditions.
