摘要
对采用覆膜砂回用砂混制湿型粘土砂的生产实践进行了介绍,包括砂处理流程、原材料的选用、砂温控制、混制工艺及在线检测等方面的控制要点;指出:采用恰当的加料顺序和混碾时间,并进行在线检测是保证湿型粘土砂质量稳定,进而使与型砂相关的铸件表面缺陷率降低的重要措施。
The productive practice of using returned phenol resin coated sand to prepare green molding sand was introduced including the sand treating flow and the essential control points in the aspects of raw materials choice, sand temperature control, sand mixing process and on-line inspection, and so on. It was pointed out by the end that adopting proper materials adding sequence, proper mixing time and, as well as, conducting on-line inspection were the important measures to guarantee stable quality of green molding sand and thereby to reduce the molding sand-relevant surface defects rate of castings.
