Linyi Public Li Xin Machinery Co., Ltd. is the design, production, processing, marketing as one of modern science and technology enterprise, using the current international advanced casting (EPC) casting a negative real heat-resistant steel manufacturer, producing more material high temperature castings, corrosion-resistant castings, wear-resistant castings, alloy steel castings and other antioxidant. Production process and quality in a leading position, with metal spectrometer, and other advanced detection equipment. Ductile iron castings as shaft parts, such as the diesel engine crankshaft, connecting rod heat-resistant steel castings, high strength at the same time requires comprehensive mechanical toughness mechanical properties of cast iron quenching and tempering treatment. Ductile iron casting process are: cast iron is heated to a temperature for 860-900 ℃ makes the matrix austenite, re-cooling in oil or molten salt to achieve quenching after tempering 500-600 ℃, access tempering cable s body tissue (usually there are a small lump of pure ferrite), the original spherical graphite morphology unchanged. Processing strength, and toughness good heat-resistant steel, castings plant shaft member adapted to working conditions. Linyi Public Li Xin Machinery Co., Ltd. is the design, production, processing, marketing as one of modern science and technology enterprises, using today's advanced international casting (EPC) of a negative real casting process, the production of high temperature casting material more resistant casting corrosion, wear resistance castings, alloy steel castings and other antioxidant. First, there are burrs on irregularly shaped appearance defects Nomenclature and Classification casting more than 14 meat castings, Phi seam or protruding parts. 15 water shortage due to the casting of molten metal is not completely filled cavity lack of meat produced. Casting shape and size and the pattern 16 due to deformation caused by shrinkage stress does not match. 17 gate burrs from the mouth while playing abrasive burrs. Linyi Public Li Xin Machinery Co., Ltd. is the design, production, processing, marketing as one of modern science and technology enterprises, using today's advanced international casting (EPC) of a negative real casting process, the production of high temperature casting material more resistant casting corrosion, wear resistance castings, alloy steel castings and other antioxidant. Production process and quality in a leading position, with metal spectrometer, and other advanced detection equipment. Shaped casting machine quality has a great influence on the mechanical function of the product. For example, machine tool castings wear resistance and dimensional invariance, directly affect the accuracy of the machine adhere to life. The primary way we accept the advances of hot metal temperature resistant steel literature, establish perfect cupola detection system, to ensure the normal form in the cupola. Shaped casting process parameters of process parameters have a greater influence on the casting dimensional accuracy and clarity round Cheng. Process via repeated experiments, for each process parameters are carefully chosen. Shaped casting forging process generally uses the latest results, the degree of progress in forging process to reduce defects in forging, casting special is the appearance of defects. Appearance refers to set quality machine casting machine casting roughness appearance, the appearance of defects, size bias, bias shape, weight bias. Shandong resistant steel _ Public Li Xin Machinery Company (certified) _ resistant steel from the Linyi Public Li Xin Machinery Limited. Linyi Public Li Xin Machinery Co., Ltd. (www.lyzlx.com) Shandong Linyi, casting leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
