高硅耐酸铸铁(高硅铸铁)具有良好的耐腐蚀性能(对于硝酸、硫酸、甲醛溶液的耐蚀能力胜过不锈钢)价格低廉,资源丰富,是我厂制造各种石油、化工、冶金和医疗等耐腐蚀设备的主要原料之一。但这种材料性硬而脆,不易切削加工。过去往往只得采用全磨削的机械加工方法,生产效率和产品质量上不去,因而也就限制了这种优良耐腐蚀材料的广泛利用。我们从长期的生产实践中,摸索出了一套加工高硅铸铁的车、钻、铣等刀具。近年来又在旅顺硬质合金厂的大力支持下,革新
High silicon cast iron (high silicon cast iron) has good corrosion resistance (corrosion resistance to nitric acid, sulfuric acid, formaldehyde solution than stainless steel) Low prices, rich resources, is our factory manufacturing a variety of petroleum, chemical, metallurgical and medical Such as corrosion-resistant equipment, one of the main raw materials. However, this material is hard and brittle, not easy to cut. In the past, it was always possible to use full-grinding machining to limit productivity and product quality, thereby limiting the widespread use of this excellent corrosion-resistant material. From the long-term production practice, we explored a set of tools for processing high silicon cast iron car, drill, milling and so on. In recent years, with the strong support of Lushun cemented carbide plant, innovation
