During the continuous production of castings,waste core sand was mixed with the waste molding sand,and the incremental sand can only be used for core making after reclaimed instead of new sand for the closed circular system.
在铸造连续生产过程中,芯砂不断地混入型砂中,循环总量增加的部分只有经过再生处理代替新砂用于制芯,才能实现系统的封闭循环。
And this process is suitable for mass production of coremaking.
试生产结果表明,采用该工艺生产出的铸件尺寸精度高、成型性好,且无需尾气处理设备,适合大批量的制芯生产。
It also presents the operating key points of coremaking,by which the high quality castings have been cast successfully.
论述了大型铸钢托轮顺序凝固原则的确定、浇注位置和分型面的选择、冒口浇注系统和砂芯的设计，指出了制芯的操作要点。
As for the hydraulic pressure castings,there are many special characteristics in the production,structure and core-making process.
液压件铸件的生产性质、结构性质及具体的生产工艺均与其它行业的铸造生产有所不同,文章通过对国内现有液压件铸件生产行业的调查研究,根据液压件铸件生产批量小、品种多及质量要求高的特点,对熔炼技术中出铁温度、成分控制、造型工艺、制芯工艺、砂处理及清理等主要生产因素初步分析,探讨液压件铸件质量的影响。
The reason causing peel back of sandcores were related to core-making equipment,core materials and core-making process.
砂芯脱壳的原因与制芯设备、制芯材料、制芯工艺有关。
