用ZGS-2型呋喃树脂代替粘土砂,进行4次浇铸Zx8.3t钢锭模的试验。首先进行涂料及涂型工艺试验,发现涂料过薄,导致“铁夹砂”缺陷。改用厚涂料后,解决了这一问题.在试验中,选择最佳配比,结果表明,用树脂砂代替粘土砂,可杜绝“缩沉”和粘土砂钢锭模的原始变形,还可节约铁水,提高产品质量。通过试验,掌握了有关铸造工艺及生产过程,积累了经验,对今后的生产具有一定的指导意义。 ZGS-2-type furan resin instead of clay sand, 4 times casting Zx8.3t ingot mold test. First of all, paint and coating technology test, found that paint is too thin, resulting in “iron sand” defects. The use of thick coatings, to solve this problem.In the experiment, the choice of the best ratio, the results show that the resin sand instead of clay sand, can eliminate “shrinkage” and clay sand ingot mold original deformation, but also save Hot metal, improve product quality. Through the experiment, mastered the casting process and production process, accumulated experience, the future of production has a certain significance.
