Springback of green sand caused by the continuous development of highly compacted molding methods and technique is one of the important factors which effects the quality and accuracy of casting. 高紧实度造型技术和方法不断发展,型砂回弹是制约铸件精度和质量的重要因素。
In this paper, the green sand molding coating for iron castings in order to improve the cast suface quality is introduced This coating has advanced technical properties. 本文介绍铸铁湿型铸造中的型腔表面使用的喷涂涂料,该涂料可有效的防止粘砂、掉砂、冲砂等铸造缺陷。
The rapid tester was described for measuring three properties of green molding sand such as compactibility, green compression strength and permeability within 90s, it is suitable fo rapid determination of green molding sand in production line. 湿型砂三性能快速测定仪,可在1分30秒内完成紧实率,湿压强度和透气率的测定,适用于湿型砂的在线快速检测。
The growing thermal load of green sand, the quicker recirculation times and the increased requirements on the quality of molding material make new demands on the molding sand preparation. 潮模砂日益增长的热负荷,更快的循环时间以及对造型材料质量要求的提高,对型砂制备提出了更高的要求。
This research mainly explores the production of steel castings with air flush molding green sand and the improvement of its character from the molding sand recipe and mold sand system control. 本研究主要探讨了用气冲造型湿型砂来生产铁路钩缓铸钢件,从型砂的配方和型砂系统的控制等几个方面来优化其性能。
