日本密烘铸铁滑动轴承公司(东京都中央区)已开始制造销售湿型砂再生加水—冷却装置(见图)。 在湿型造型线中,再生砂在没有进行充分冷却的情况下成为所谓的“热砂”,因此,铸型变得干燥,表面的砂不稳定,从而导致废品率上升,这成了湿型砂造型的最大的问题。 在再生砂中加水并使砂冷却的装置由于在加水的方法上存在问题,故未能找到解决消除“热砂”的有效方法。 Bimetal Japan Casting Co., Ltd. (Chuo Ward, Tokyo) has started to manufacture and sell wet sand regeneration water-cooling units (see photo). In the wet-type molding line, the reclaimed sand becomes the so-called “hot sand” without sufficient cooling, so that the mold becomes dry and the surface sand is not stable, resulting in an increase in reject rate, which results in wet sand The biggest problem modeling. The means of adding water to the reclaimed sand and cooling the sand failed to find an effective solution to the elimination of “hot sand” due to problems with the method of adding water.
