钢铸件的生产过程中,防止铸件表面产生粘砂是一个很重要的问题,由于产生粘砂,则降低了铸件的外观质量,增加了清理铸件、尤其是有细长孔铸件的劳动量。我们试用了碳质造型材料,以求解决这个问题。
Preventing the production of sticky sand on the surface of castings is an important issue in the production of steel castings. The appearance of sticky sand reduces the appearance of castings and increases the amount of labor required to clean castings, especially those with elongated holes. We tried a carbonaceous modeling material to solve this problem.
