Heat-resistant steel - EPC process of the bed of the casting process design three gating system design gating system design is correct or not size, is the most important issue of the availability of qualified casting. In the EPC casting process, molten iron in the cavity affect its liquidity by the appearance of a decomposition product of heat loss and the appearance of resistance vaporization process of liquid iron. Usually it is difficult to make a precise calculation, therefore, often using general gating system calculation method, and the resulting value of 50% to 100% zoom. To facilitate the production of a single runner-sectional area as 201mm × 20mm. Holes and pores, to ensure the quality of the machine bed rail. Linyi Public Li Xin Machinery Co., Ltd. is the design, production, processing, marketing as one of modern science and technology enterprises, producing more material high temperature, corrosion, abrasion, oxidation alloy steel castings. The company can according to user needs and design, manufacture a variety of materials dedicated foundry products: floor furnace, furnace tank, box, blades, axes, linked with, spreader, baskets, trays, grates, crucible. The company will be a stable product quality, heat-resistant steel wear-resistant steel, high-quality service and dedication to new and old customers work together for a better future! Heat-resistant steel -? Negative eutrophication fast burning shell casting operation essentials of burning foam because it contains four O air flow along the feeder Sinking burn empty inside, heat-resistant steel, enough to supply the mouth of the bubble risk burning. But burn the following parts of the riser after the combustion area increases, heat-resistant steel prices, from the riser is drawn into the air stream O? Beyond insufficient for EPS required for combustion, so at this time the need to reduce gas output amount (or even shut off the gas adjustment valve) and increased O? is input to the depths in the supplemental type O? deficiencies. O? Amount actually available for input output O? Inner diameter of the tube to control the size of its output and is usually about the same amount of artificial respiration, diameter? 3 ~ 4mm of oxygen tube oxygen valve can be opened up.
