Dongguan Precision CastingThe smelting is based on the user's request or considering the production cost. When small batches of special steel or steel grades with more than 3% carbon, manganese, and chromium are produced, it is usually smelted in an arc shield, such as a 40-ton electric arc furnace. Most of the steel keys are produced by the HKV method, which is the transfer betting method of Henry Steel Works.

Precision casting processing

In steel mills, depending on the quality requirements, the following processes can be adopted:-Desulfurization of low-phosphorus pig iron with the Rhein Steel Mill's mixing method,-Using the "low phosphorus" method to desulfurize pig iron and pass The selected scrap steel is refined,-the steel is tapped in a preheated ladle with an excellent lining,-the molten steel is mixed with a gas to make it uniform. First, to minimize the sulfur content, the molten steel is treated with calcium according to the TN technology ,-Use RH method for vacuum treatment, if necessary, use it in conjunction with vacuum carbon deoxygenation or vacuum decarburization method, which can reduce the carbon content to a minimum,Precision cast steelThe final bet is made, and gas maintenance should be used if necessary. The use of excellent furnace linings in the ladle, such as high-aluminum p-oxidation or self-marble furnace linings, is to prevent the exhausted oxygen from adversely affecting the purity of the steel ingots used for precision casting.

Coffee machine accessoriesMechanical basic components mainly refer to: bearings, gears, molds, hydraulic parts, pneumatic components, seals, fasteners, etc., which are indispensable main components of the equipment manufacturing industry, and directly determine the functions of serious equipment and host products. Level, quality and reliability. The precision casting processing plant is gradually developing, and the results are getting better day by day.
