Single production bearing cap castings, corrosion resistant castings Public Li Xin (certified), casting Li Xin Machinery Co., Ltd. is provided by Linyi congregation. Linyi Public Li Xin Machinery Co., Ltd. (www.lyzlx.com) is specialized in the "steel castings, cast steel, heat-resistant steel, ordinary steel castings," the enterprise, the company of "honesty, hard service" concept, for you provide the highest quality products and services. Welcome to inquire! Contact: Peng. 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. Heat-resistant steel for prolonged running environment, is constant over time, as will be some defects. This drawback for the opportunity for all metals are so, like car tires need to be replaced after a long period of time and wear the same speed. The phenomenon of heat-resistant steel and automobile tires, as will over time be some changes on the phenomenon of performance. E.g. carbide, metal compounds and the like precipitated. These effects are referred to as time triggered: aging. It has a kind of link between aging and heat resistant steels? Here for everyone of heat-resistant steel castings. 1, timeliness just the beginning, for the negative impact of heat-resistant steel is not only not too large, but also conducive to the heat-resistant steel. Because the aging time just started, because there is a small heat-resistant steel reinforcing help phase, become more strength and hardness. But this time, the plastic heat-resistant steel is decreased, the toughness is also true. 2, with increasing aging time, this time for the impact of heat-resistant steel is very unfavorable, because small changes relatively slowly becomes large, resulting in strength heat-resistant steel, the hardness and other performance decline phenomenon.

Production process and quality in a leading position in the casting, with a metal spectrometer, and other advanced detection equipment. Alloy steel casting process in the production of ductile castings production methods, many issues need attention, otherwise it is easy to accidentally cause a defect, which is equal to produce a defective product for a passing rate is has a great impact today to tell you about the precautions in the production process: 1, riser, large alloy steel castings to consider repair and heat insulation riser or riser, placement must be reasonable. 2, the core of high-chromium cast manufacturers, alloy steel casting core have enough strength to keep the airway smooth. 3, casting method, large alloy steel castings for the chemical pump stainless steel castings, often multi-runner runner dispersed, layered, not even a closed or semi-closed bottom gating system, but they use a fast pouring, flat runner. 4, cold iron, alloy steel casting in order to ensure uniform solidification, the need for cold iron surface can not have rust, cold iron on the surface to be paint, before cold iron alloy castings poured more preferably with hot air heat, cold iron between There are some sand, cold iron alloy steel casting thickness should be 0.5 to 1.0 times the thickness. 5, pit, pit is the production of large cast alloy steel castings is a major feature, can reduce sand box, simplifying the sand box structure, in order to reduce weight lifting, pouring pit to reduce the height of the runner plane to prevent molten iron splash , ease of operation and safety, large alloy steel casting solidification cooling time is long, the pit can insulation, may be appropriate to eliminate casting stress.
