静压造型是一种新型的铸造工艺,为推广其在铸钢生产中的应用,开展了对造型原材料(原砂、膨润土、附加物)及铸造工艺的应用研究。结果表明,采用粘土湿型砂静压造型工艺生产铸钢件,所选用的原材料、铸造工艺、配砂工艺等,各项技术指标均达了要求,能够批量生产高质量的铸钢件,经济技术效益显著。 Static pressure molding is a new type of casting process. In order to promote its application in the production of cast steel, applied research has been carried out on the modeling raw materials (original sand, bentonite, addenda) and casting process. The results show that all the technical indexes of the castings, the selected raw materials, the casting technology and the sand preparation technology are all produced by the static pressure molding process of clay wet sand, which can produce high quality steel castings, economical technology Benefit significantly.
