Red May for chemical industry workers! Reply reward! ---------------------------------------------- The past decade has been a period of rapid development for China’s chemical industry, marked by the emergence of many new processes, products, and equipment. There has also been significant progress in China’s chemical processing equipment, which has contributed to the swift advancement of the petrochemical sector. Here, we have compiled some of the achievements and breakthroughs made by Chinese equipment manufacturers in terms of larger-scale production and greater use of domestic equipment. We invite everyone to share their insights and engage in discussions, to cheer for Made in China and to support the development of chemical processing equipment! ===================== On May 7, the acceptance of the clean steel platform construction project for large-scale castings and forgings at China National First Heavy Machinery Corporation, which was overseen by MCC Jingcheng as the general contractor, was essentially completed. This marked the full completion of the project, representing a significant achievement for MCC Jingcheng in the field of developing major equipment in China. China First Heavy Machinery Co., Ltd. was formerly known as China First Heavy Machinery Factory, and it was one of the 156 key construction projects during China’s First Five-Year Plan period. After years of development, China National Heavy Machinery Corporation has now become a **large-scale enterprise** in China dedicated to the research, development, and production of heavy equipment. It holds a leading position in the equipment manufacturing industry, representing China’s capabilities and standards in the production of large-scale cast and forged components. It is one of the key enterprises in China’s domestic heavy equipment industry, and was once hailed by Premier Zhou Enlai as a \"national treasure\". Before the renovation project commenced, the existing level of equipment at China National Heavy Machinery Corporation had become a constraint on the company’s further development; the construction of a clean steel platform for large-scale casting and forging components was aimed at upgrading this existing equipment. Through multiple on-site inspections and expert evaluations, MCC Jingcheng upgraded and renovated the 100t electric furnace, 80t electric furnace, 40t electric furnace, 40T refining furnace, new 130T refining furnace, old 130T refining furnace, 160T refining furnace, as well as the associated auxiliary facilities in the steel casting workshop, thereby improving and enhancing China First Heavy Industries’ ultra-pure smelting technology for large-scale cast and forged parts. The project construction overcame the organizational challenges associated with carrying out production and construction simultaneously on site, providing strong technical support for the timely commissioning of the project. It demonstrated the considerable technical capabilities of MCC Jingcheng, both within China National Heavy Machinery Corporation and in the entire industry of developing large-scale equipment. With the completion and commissioning of the entire project, MCC Jingcheng helped China National Heavy Machinery Corporation modernize its equipment for the manufacturing of large-scale cast and forged parts, achieving automation in operations, intelligence in manufacturing processes, and informatization in management. This effort transformed China National Heavy Machinery Corporation into a modern production base for large-scale cast and forged parts with international competitive capabilities, thereby making contributions to the metallurgy industry and the development of heavy machinery.
China National Heavy Machinery Corporation is the largest heavy machinery manufacturing enterprise in China, focusing on the production of heavy equipment for industries such as steel rolling, metallurgy, forging, power generation, and petrochemicals. It now has the capability to produce 700-ton batches of molten steel, castings with a weight of over 500 tons per batch, steel ingots of 300 tons in weight, and forged parts of 200 tons in weight. The manufacturing technology for the forged-welded heat-wall hydrogenation reactors and coal direct liquefaction reactors produced by this company has also reached international advanced levels, and it was the first in the world to undertake manufacturing contracts for forgings of the main equipment in third-generation pressurized water reactor AP1000 nuclear islands. China National Heavy Machinery Corporation’s “Project to Build a World-Class Foundry and Forging Steel Base and to Upgrade Technologies for Domestic Production of Large-Scale Foundry and Forging Parts” was approved by the **National Development and Reform Commission at the end of 2007. Recently, all the newly expanded factories have been completed; the delivery timelines and long-term procurement processes are essentially finished. These facilities have now begun to undertake the production of large-scale cast and forged components for key projects such as **under-construction nuclear power plants and large hydroelectric stations with a capacity of over 700,000 kilowatts. By 2010, China National Heavy Machinery Corporation is expected to produce 500,000 tons of molten steel per year, 240,000–250,000 tons of forgings per year, and 60,000–70,000 tons of forged and cast steel products per year. Its production capacity will reach the world-class level defined by the “7654” standard, which entails the ability to produce 700 tons of molten steel at a time, 600 tons of ingots, 500 tons of cast parts, and 400 tons of forgings. This will ensure that its core forging and casting technologies remain at the cutting edge for 20 years, enabling it to rank first in the world in terms of production volume per ton. By then, China’s production of cast and forged parts will account for 25% of the world’s total, thereby completely reversing the situation in which China has long relied on imports for high-end, large-scale cast and forged products.
Keep core casting and forging technologies ahead by 20 years, and achieve world-leading production volumes per tonnage.
