Wear-resistant castings are consumables in important industrial fields such as mining, metallurgy, building materials, electricity, petrochemicals, machinery, and transportation, and occupy a very important position in industrial production. According to incomplete statistics, the annual domestic consumption exceeds 2 million tons. Currently, there are nearly 1,000 wear-resistant casting manufacturers. The annual production capacity in Shanghai has reached more than 5 million tons, and the casting process has been various.
Development of wear-resistant castings by V-process:
V-method casting was a kind of production technology originated in Japan in 1973. After the introduction of China in the 1980s, it was widely concerned and gradually applied to the production of many products. At the same time, the process was introduced to North America and Europe, and it has made great progress. The scope of application has been continuously expanding. It has achieved very mature applications in the fields of forklift counterweights, construction machinery axle housings, and bathtubs.
Among the series of wear-resistant castings, the V-casting process has achieved great success in the use of many well-known wear-resistant castings manufacturers in the West and has gradually become the mainstream process of these companies. In China, from the 1980s onwards, there was a preliminary exploration of this process for the production of wear-resistant castings, but there was no mature application (except for railroad ballasts).
In recent years, in the field of wear-resistant castings, the V-method casting process has regained attention and attention. At present, the V-method casting is mainly based on traditional mine wear-resistant castings in the production and application of wear-resistant castings, including high-manganese steel cones, tooth plates, hammerheads, plate hammers, and large-scale liners. Even some companies succeeded in producing V-roller castings for vertical mills using the V-method casting process and achieved good results.
Reasons for using V casting:
According to domestic and foreign experience, V-casting has high quality of products on wear-resistant castings, and the environment-friendly advantages are one of the important reasons why people choose this process. The advantages of cost and environmental protection are well-known, but the quality advantage is that in addition to the high surface quality and high dimensional accuracy of the V process itself, the low temperature casting makes it possible to improve the wear resistance of the grains. There is a certain amount of exploration value.http://www.pump-casting.com/
