Steel Castings plant | Public Li Xin Casting factory | Exemplifying casting plant from Linyi Public Li Xin Machinery Limited. 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 casting manufacturer is specially heat-resistant steel, heat-resistant steel castings, heat-resistant steel products manufacturers. Heat-resistant steel manufacturers in the production of heat-resistant steel pearlite, they sometimes find that the phenomenon of heat-resistant steel balls appear. So what caused the emergence of resistant steel ball phenomenon it? Today, heat-resistant steel manufacturer for everyone Brief Description cause heat occurs under the ball of the reasons for the phenomenon. The main factors that led to emergence of resistant steel ball as long as the phenomenon: ① temperature: heat-resistant steel in high temperature environment, there will inevitably be affected by high temperatures. When the temperature is higher when the casting plant, heat-resistant steel ball speed will be faster. ② time: long-term heat-resistant steel at high temperatures, because of the relationship to work long hours at high temperatures lead to more serious ball. ③ components: heat-resistant steel of composition is important, but also resistance to high temperature, a key factor of the watch. By the above, we understand the reasons of heat ball, then the ball will appear caused by heat-resisting steel how kind of impact? Here resistant steel manufacturers for you on the. For heat-resistant steel ball impact is mainly reflected in the normal temperature performance and high temperature performance. The ball will result in reduced strength and hardness of the heat-resistant steel, but also speed up the process of creep. So to prevent the emergence of pearlite heat resistant steel for heat-resistant steel ball phenomenon is very important in terms of the manufacturer. 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. Presumably some of the parameters of alloy steel castings we have a certain understanding, then give you some technical requirements for steel castings factory, to discuss with you today is the welding requirements. The following summarizes the four related content, you can read about: 1, alloy steel casting defects allow welding, welding defective parts shall be cleaned before, after welding should not affect the use and appearance quality castings. 2, an important part of important large steel castings factory, ready for welding surface groove depth of more than 20% of the wall thickness or 25mm (depth so whichever mouth), the groove when the area of ??more than 65mm2 it instead major welding. 3, the major welding welding should record the location and scope, welding conditions are confirmed by the technical department of casting processing factories, after welding shall be in accordance with the same standard test test castings. 4, alloy steel castings by welding a large range, or significant after welding, whether tough process again, determined by the quality control department.
