前 言 目前,微波加热技术在食品、木材、皮革、彩色印刷等轻工业部门中已广泛采用,在铸造生产中采用微波加热技术则尚处于试验研究阶段。据国外资料介绍,在熔模铸造中微波脱腊速度快,型壳强度高,可连续生产,并能焙烧型壳。微波固化树脂砂型芯,可以改善型芯尺寸精度,缩短固化时间,提高生产效率,节省能源。 Preface At present, microwave heating technology has been widely used in light industrial sectors such as food, wood, leather and color printing. The use of microwave heating in foundry production is still in the experimental stage. According to foreign information, in the investment casting microwave degreasing speed, high-strength shell, continuous production, and can roasting shell. Microwave curing resin sand core, can improve the core size accuracy, shorten the curing time, improve production efficiency and save energy.
