从目前来看,大多数生产铝合金铸件的厂家在低压铸造生产中,所采用的浇注管的材料是无缝钢管或铸铁管,采用这两种材料制作浇注管的弊病是:1.使用寿命短(连续生产一般在30～48小时,二班制生产一般在200小时以下)。2.铝合金液增铁,严重影响铸件内在质量。为了解决这两个问题,我们用氟金云母材料制作低压铸造浇注管并作了生产性试验 From the current point of view, most of the manufacturers of aluminum alloy castings in the production of low-pressure casting, casting pipe used in the material is seamless steel pipe or cast iron pipe, the disadvantages of using these two materials pouring pipe is: 1. Life Short (continuous production is generally 30 to 48 hours, two shifts are generally less than 200 hours). 2. Aluminum alloy liquid iron, seriously affecting the quality of the casting. In order to solve these two problems, we made low-pressure casting pouring tube with fluorophlogopite and made productive test
