Product details:

The results of monel 400 round steel show that rare earth has good metamorphism in the alloy, mainly refining grain and dendrite. The atomic radius of rare earth element is larger than that of aluminum atom, and its properties are more active. It is easy to fill in the surface defects of alloy phase when melted in aluminum solution, which makes the interface tension between old and new phases, and the growth rate of crystal nucleus. At the same time, the surface active film is formed between grain and alloy solution, and the resulting grain grows up and refines the alloy structure. The addition of rare earth can also control the grain size of materials to some extent, such as columnar and secondary dendrite arm spacing, grain morphology and so on. The experiments show that the rare earth metamorphism has a certain incubation period, and only when it is maintained at high temperature for a certain time, the rare earth metamorphism will play a big role. 3.2 refining and purification rare earth has a good purification effect on aluminum alloy melt. First of all, rare earth is easy to form chemical compounds such as RE2O3, RE2S3, RES, RES2, RE3S4, REH2, REH3, REX3(X is a halogen element) with O, S, halogen elements, etc., and reacts with N to form refractory REN at 250 ~ 300℃.

Foreign-funded enterprises are higher than other enterprises, and those in the south are higher than those in the north. This is evident in guangdong. Guangdong has a large number of foreign-funded enterprises, which drive the change of other enterprises' concepts and the development of the market. Therefore, the use coverage of high temperature alloy bolts, enterprise high temperature alloy bolts and parts in guangdong is much higher than that in other areas. The implementation of high temperature alloy bolts, using high temperature alloy bolts, parts, not only can effectively improve the high temperature alloy bolts, but also can high temperature alloy bolts, production cost and greatly shorten the high temperature alloy bolts, production cycle. Relevant statistics show that the adoption of high temperature alloy bolts and parts can save 25%-45% of the working hours of high temperature alloy bolts and shorten the production cycle of high temperature alloy bolts and parts by 30%-40%. With the development of multi-varieties, small-batch, personalized and fast-cycle production of industrial products, in order to improve the rapid strain capacity and competitiveness in the market economy, the production cycle of superalloy bolts is becoming more and more important, and the significance of superalloy bolts and transformation is more significant. High temperature alloy bolts, parts production and demand overview due to high temperature alloy bolts, the work started late, slow progress, plus the past "big and complete", "small and complete", "from the production and distribution" and other old ideas, therefore, high temperature alloy bolts, parts for a long time has been the variety of specifications, small production scale, not smooth circulation.
