the largest cost of the machine shop cost of the cost of the products, so Hangzhou Yu Chen Machinery Co., Ltd. provides processing castings Service, easier to cut, so that the product life longer. Yu Chen mainly provides Hangzhou gray iron processing , machining, ball paste processing and so on.

    the long time exposure of iron to the air is prone to corrosion and gray iron castings will also have similar conditions, and its quality affects the use and performance of the products. Therefore, how to prevent gray iron castings is an important task for the vast majority of manufacturers.

    Yu Chen, based on the experience of many years of gray iron processing, shared some ideas that, in the process of making, the first problem is that the gray iron castings need to be released at high temperatures and reduce the effect of impurities on it when they are out of the furnace. Add a certain amount of spheroidizing agent when necessary. On the corrosion prevention of gray iron castings, in order to achieve better results, a layer of zinc can be plated on the surface to avoid direct contact with oxygen in the gray iron casting and air. In addition, the clay content of gray iron castings is high, and it contains less moisture. Therefore, its main defect is that it is easy to loose in the process of production and processing. Therefore, the proportion of the two should be well controlled in the process of manufacturing.
