1983年9月19日至23日联邦德国机械制造代表团(VDMA),在沪进行了内容广泛的铸造设备与车间设计等方面的技术座谈。其中,艾里希(Gustav Eirich)机器厂的代表,介绍了用于树脂与粘土湿型砂系统的旧砂再生装置。这种旧砂再生装置的设计思想,是使目前广泛应用的树脂砂或粘土砂湿型砂系统,能形成一个封闭循环系统,即砂子能反复循环使用。这样,不仅减少新砂消耗,降低铸件成本,而且能保证型砂性能稳定,减少铸件的废品。这种新开发的旧砂再生装置,其原理
From September 19 to September 23, 1983, the Federal German Machinery Manufacturing Delegation (VDMA) conducted a technical discussion in Shanghai covering a wide range of foundry equipment and plant design. Among them, the representative of the Gustav Eirich plant introduced the old sand reclamation plant for resinous and clay wet sand systems. The design concept of the old sand regeneration device is to make the currently widely used resin sand or clay sand wet sand system form a closed circulation system in which the sand can be recycled repeatedly. In this way, not only reduce the consumption of new sand, reduce the cost of castings, but also to ensure the stability of sand and reduce the castings of waste. This new development of the old sand regeneration device, the principle
