5.Project Profile(not over1200 words):
science and technologyField:Technical field of metal casting
MainTechnical content andInnovation points:This topic research formed“Method for producing malleable cast iron pipe fittings using recycled scrap", its technological innovation is mainlyYes:Improved malleable cast iron induction furnace melting process, the traditional process of metal charge needs to use near.The formula of 50% steelmaking pig iron is changed to machine iron and scrap steel as the main raw materials, with rapid analysis in front of the furnace and white mouth detection of triangular samples, which provides high-quality white iron blanks for forging casting fittings and reduces production costs..
Main technologyContent:For the pipe casting industry, the cupola is widely used as a melting tool, casting pig iron as the main raw material, the production of malleable cast iron pipe fittings in the energy consumption, pollution.Serious, easy to get out"Ash parts", low casting pass rate, our company through technical research, developed the use of medium frequency electric furnace melting process, waste machine iron, scrap steel as the main raw material, through the electric furnace melting process.andoptimization of raw material ratio, reducedAbout80%ofcarbon emissions,Improved the matrix organization of the cast blank parts, stabilized the performance of the product, reduced the casting.The phenomenon of "gray parts" reduces the scrap rate of product casting.,In line with General Secretary Xi Jinping's4Month22Proposed by Japanese leaders at climate summitImplementationCarbon Peak, carbon neutralrequirements.
Innovation points:1,Invented a method of producing malleable cast iron fittings using recycled waste, using malleable cast iron induction furnace melting process,SubstituteAscendFurnace smelting,developedFullNewProduction process technology insteadtraditional process, reduces carbon emissions, hasUrban Minerals,The advantages of circular economy, energy saving and environmental protection.
2, invented.Automatic internal and external screw processing machine, Improve the appearance quality of the pipe fittings, ensure the accuracy of the pipe thread, and improve the work efficiency.
3, successfully developed a good wear-resistant integral casting plate, to solve the existing split casting plate model positioning accuracy is difficult to guarantee the problem, to avoid the sand casting mold in the process of upper and lower box deviation phenomenon, improve the qualified rate of casting products.
4、Invented a waste dedusting device for aluminum furnace,Reduced energy consumption in the aluminum melting process, improved dust removal efficiency, reducedcarbon emissions,realizedgreen low carbon,High quality low consumption target.
5,Participate in the development《Test method for wedge compressive strength of cast iron》Trapezoidal Thread Part 3: Basic Dimensions Trapezoidal ThreadPart IV: Tolerances, Iron CastingsClassification and Naming of Casting Defects》Wait4national standards;
