Linyi Public Li Xin Machinery Co., Ltd. located in Junan County Economic and Technological Development Zone, located in the southeast of Shandong Province Rusu junction gate valve casting, set design, production, processing, marketing as one of modern science and technology enterprises, the use of advanced international today The casting (EPC) a negative real casting casting, production of multi-material high temperature, corrosion, abrasion, oxidation resistance alloy steel castings. The products are widely used in metallurgy, mining, chemicals, shipbuilding, paper, machinery, military and other industries. Production process and quality in a leading position, with metal spectrometer, and other advanced detection equipment. The company can design according to user needs, manufacturing a variety of standard and non-standard special foundry products. Many factors affect the quality of castings, the first is the design of the process of casting. When the design, in addition to determining the casting geometry, size according to the working conditions and the metal material properties, but also must be from the perspective of casting alloys and casting process characteristics to consider the design is reasonable, that is a significant size effect and solidification shrinkage stress and other problems steel casting plant, in order to avoid or reduce the casting composition segregation, deformation, cracks and other defects generation. The second to have a reasonable casting process. That is according to the casting structure, weight and size, cast alloy properties and production conditions, select the appropriate sub-surface and shape, making the core method, a reasonable set casting bars, cold iron, riser and pouring systems. To ensure access to quality castings. The third is the casting quality of raw materials. Quality metal charge, refractories, fuel, flux, modifier and foundry sand, sand binders, coatings and other materials, sub-standard, will make casting porosity, pinholes, slag, sticky sand and other defects, affecting the appearance quality castings and internal quality, serious cause casting scrap. The fourth is the process operation, to develop a reasonable process rules to enhance the skills of the workers, so that technical rules properly implemented. Linyi Public Li Xin Machinery Co., Ltd. located in Junan County Economic and Technological Development Zone, located in the southeast of Shandong Province Rusu junction, is the design, production, processing, marketing as one of modern science and technology enterprises, the use of advanced international cast today Process (EPC) a negative real casting process, production and more material high temperature, corrosion, abrasion, oxidation resistance alloy steel castings. Investment casting, also known as "casting" or "lost wax casting" and "cast" can be very extensive melting of the material, but also the shape of the complex structure of the product is not restricted. The most important feature is its size control precision, machining cutting margin rarely, smooth surface, with the gradual introduction of new advanced equipment and technology, the scope of which can be applied more widely. In the field of thermal processing, drawing hard or difficult pieces molded parts as well as some high processing costs of forging steel casting, investment casting applicable; and in the field of casting, investment casting, some products can be used to replace other forms of casting, Machining margin reduction to reduce costs and improve the dimensional accuracy and surface roughness and mechanical properties of the material, so as to achieve the purpose of upgrading product quality.
