Linyi Public Li Xin Machinery Co., Ltd. is the design, production, processing, marketing as one of modern science and technology enterprise, the use of advanced international casting today (EPC) of a negative real casting process to produce more material casting temperature resistance corrosion castings, abrasion resistant castings, steel castings and other antioxidant. 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. Our company is specialized in the production of precision steel castings company, mainly engaged in all kinds of steel castings, forgings and forging parts and other steel castings, alloy steel castings to introduce the following production safety technology: 1, based on the total number of alloying elements alloy steel castings can be divided into two low-alloy steel castings and high alloy steel castings categories. 2, low-alloy steel castings, our main application manganese, silicon manganese and chromium, etc., as ZG40Mn, ZG30MnSi1, ZG30Cr1MnSi1 so on. Used to make gears, hydraulic press cylinder and turbine rotor and other parts, and ZG40Cr1 used to manufacture high-strength and high-strength gear shafts and other important force components. 3, high-alloy steel castings, with wear or corrosion resistant carbon steel castings and other special properties, such as high manganese steel castings ZGMn13 is a wear-resistant steel, mainly used in the manufacture of dry friction in working conditions parts used, such as grab the front wall and grab teeth, tractors and tanks crawler excavators etc; chrome-nickel stainless steel and chrome ZG1Cr18Ni9 ZGCr28 ZG1Cr13 and other highly corrosive nitric acid resistant, mainly for the manufacture of chemical , spare parts and equipment on the oil, chemical and food.

Alloy Steel Castings after heat treatment should be used because the internal cast steel castings in the presence of pores, cracks, shrinkage and shrinkage, coarse grains, tissue and internal residual stress uneven casting defects, making steel castings strength, especially ductility and toughness greatly reduced. For grain refinement, uniform organization and eliminate stress, alloy steel castings must be normalized or annealed. After normalizing the steel, the higher the mechanical properties after annealing, the cost is low, so more often. However, due to normalizing annealing treatment can cause relatively large internal stress, apply only to the carbon content of less than 0.35% of steel castings. Because the plastic carbon steel castings good casting process, easy to crack when cooled. To reduce stress, alloy steel castings, after normalizing, tempering should be carried out. For ≥0.35% carbon content, complex structure and easy to crack the steel castings, can be annealed. Should not be quenched steel castings, or vulnerable to cracking.
