But overall, the current Zhongshan mold steel market still lags behind the needs of mold industrial development. According mold experts, a considerable part of the requirements of high mold steel need to go through the vacuum refining and remelting to ensure high purity steel, high density, higher anisotropy, of which more than general quality mold steel, high-quality less steel mold, and mold steel by remelting share is small. Zhongshan die steel market is about 80 percent black round bar, at present, alloy tool steel production in China has been in the world, of which about 100,000 tons alloy tool steel. Eutectoid steel and forgings for eutectoid steel, or tools, dies, ball bearing steel pearlite, the ball carbide QRO-90 price, refine the organization, eliminate stress, reduce hardness, improved ductility, toughness . Heated to 20-30 degrees Celsius above Ac1 annealing, Ac1 20-30 degrees Celsius above the ball. Heating holding time and fully annealed same. When cooled to 20-30 degrees Celsius per hour speed of the ball is cooled to a temperature, the ball after cooling to 450-500 degrees Celsius oven baked. With various domestic operating costs increased year by year, the steel infrastructure ideas also tend to go out, Southeast Asia, such as Indonesia, Myanmar, Vietnam is becoming a popular investment treasure. Indonesia, which is due to make policies to attract a large number of domestic manufacturers to invest settled, but factors such as political instability in Indonesia this year, firmly implement the ban on mining, investors wait and see situation in subsequent indecisive, the actual start start building or less. Isothermal annealing is mainly used to refine the organization of carbon steel, alloy steel forgings, stampings, etc., reduce the hardness to prevent white spots and even organizations. Annealing is heated to 30-50 degrees Celsius above Ac3, isothermal above Ac1 20-30 degrees Celsius, insulation can be adopted in accordance with the fully annealed. Cooling rapidly cooled to below Ac1 isotherm. Isothermal time more important: Carbon 12 hours, alloy 3-4 hours. And so the end of the warm time, remove the air cooling. Foreign anti-dumping actually not much impact at this stage the uproar over the size of the domestic steel mills, steel production, after all, the product of such regular, reliable QRO-90, in the eyes of foreigners peer fair price of gold is still very full, Under the circumstances the conduct informal channels are also, not only does the anti-dumping storm blowing its body, but also the opportunity to get rid of the market in shoddy, disrupt the black sheep of the international market trading order. So basically these mills sit back, quite see Pretrial blossom, since the extra cash I chic style. Shantou increasingly large steel mold, especially molding parts increasingly large QRO-90 rod, in order to improve production efficiency QRO-90 Wholesalers, a multi-cavity mold, so a large block of steel demand will increase year by year; precision molds more to the higher requirements of good quality steel, high dimensional accuracy, good stability; the demand for plastic mold steels, die casting mold steel is increasing; the demand for high-grade steel mold growing increasingly surplus low-grade tool steel.
