辉绿岩制品简称铸石,由于它具有良好的耐磨和抗腐蚀性能,所以在很多地方都得到了广泛的应用。由于有限的铸石产品品种,往往满足不了生产上的要求。所以当生产用量很小时就需要对大块铸石板进行“切割”。最近,我们在对 SZ124型混砂机嵌铸石时,采用了电阻丝切割法获得了成功。现将切割方法介绍如下:先取半张10毫米厚的石棉板,用小刀或螺丝刀在一面刻出5毫米宽,3 Diabase products referred to as cast stone, because of its good wear and corrosion resistance, so in many places have been widely used. Due to the limited variety of cast stone products, often can not meet the production requirements. So when the production amount is very small, we need to “cut” the large cast slab. Recently, we used the resistance wire cutting method to successfully cast stone for SZ124 sand mixer. The cutting method is introduced as follows: Take a half asbestos board 10 mm thick, with a knife or a screwdriver engraved on one side 5 mm wide, 3
