According to the needs of the domestic steel industry development trends and mold manufacturing tungsten steel mold market, seize the development of high-precision, high toughness, corrosion resistance, high-quality new varieties of mold steel, making domestic hot and cold work die steel to the world advanced level. Shantou mold steel is the basis for industrial production technology and equipment, with mold parts with high accuracy, high complexity, high consistency, high productivity and low consumption advantages, with the rapid development of industry, China's mold manufacturing industry a huge space . It is predicted that in 2010 ~ 2015, China's mold industry with an average annual growth rate will be around 10%, in 2015 - 2020 at 8% or so. According to the "mold industry," second five "development plan", to 2015, China's total sales will reach 174 billion yuan mold, of which exports accounted for about 15 percent die, that is about $ 4 billion; domestic market, domestic self-made molds rate of more than 85%, the proportion of high-grade die more than 40%; the elimination of cold work hardening, recrystallization, refining and homogenizing tissue. Recrystallization annealing, in order to continue processing and may be used at a relatively high temperature heating: Ac1 above 50-150 ° C, there are many kinds of steel phase transformation may occur. After changing furnace cooling. If, after recrystallization for direct use, then the need to control the grain size should be at a relatively low temperature, such as the general steel is heated at 650-700 ° C. Holding time for a relatively large cross-sectional size of the pieces by 3-4min / mm, for relatively small pieces generally holding time more than 2-3 hours. Cooling annealing method. Actually imported from Japan FD15 tungsten steel, the recrystallization temperature and is largely dependent on the degree of occurrence of deformation. If the conditions can be considered full recrystallization heating temperature according to the recrystallization of the metal. To be able to quickly and efficiently remove the remainder of tungsten steel RD30 suppliers, and have high reliability, in order to maintain long-term continuous full-load operation, the table size should fit the mold dimensions, suitable for rectangular or square and round, should not be long and narrow, and the height and direction of travel but requires a larger space. Machinery casting machine after being eliminated or end of life, can be remanufactured by creating new value, creating a post-market services, and the formation of larger profit margins. Die Casting Industry fairly quickly. Dongguan mold steel This is mainly because: first, the number of foreign companies generally do not die casting more than one hundred people, most of the mold foundry number fifty people look at their personnel structure arrangement is also very reasonable. Recent studies show that mold steel by cryogenic treatment (-196 ℃), can improve its mechanical properties, some die after cryogenic treatment significantly increased service life. Cryogenic steel mold can be between quenching and tempering processes carried out, but also for cryogenic treatment after quenching and tempering. If you still retain residual austenite in quenched and tempered steels, then after cryogenic treatment remains tempered once again. For strict security product quality tungsten steel VA50, bearing steel hot-rolled coil Division was established research team, with clients in-depth exchanges and communication, organize technical and production departments on product performance, sizes and other formulated in advance, audit, issued production technology procedures, and job training for system employees. For production, process control and difficult to develop a detailed trial plan, in the production process, the Ministry of engineers focused their attention on two-stage process technology field guide, by adjusting the proportion of structural steel in carbon, silicon, manganese, phosphorus, sulfur and other elements, optimization vanadium, boron shooting range, which protective cast, to ensure that the slab quality to meet the requirements.
