China's casting industry to high-end development
Pubdate date:2019-10-17Views:0
The 2010 China International Foundry Expo and the 10th China International Foundry, Forging and Industrial Furnace Exhibition were held recently at the Beijing New International Exhibition Center. The four-day exhibition showed the Chinese foundry industry after the global financial crisis. The policy of the adjustment and revitalization plan of the manufacturing industry has accelerated the pace of adjustment and upgrading of its industrial structure, and exhibited a number of latest independent research and development results of large-scale and high-end castings and forgings related to the core components of the equipment manufacturing industry.

      Among them are: the world's largest single-piece ductile iron parts, the world's most advanced gas engine frame, and 3 megawatt wheel castings and other large-scale key castings and forgings such as wind power and nuclear power. The collective appearance of these high-end and large-scale core castings and forgings means that while the casting production has been ranked first in the world for ten consecutive years, China's foundry industry has launched a tackling strategy for the independent manufacturing of high-end castings.

      First, the casting technology has developed by leaps and bounds, and innovative products are constantly emerging.

      This year's show exhibited a number of large and high-end castings related to the core of the equipment manufacturing industry, and achieved new breakthroughs in independent innovation.

      1, 135 tons of the world's largest single ductile iron machine tool castings
      Beiyi Heavy Machinery Manufacturing Co., Ltd. exhibited a self-developed 135-ton ductile iron machine tool casting. The casting is 19.5 meters long, 2.25 meters wide and 1.5 meters high. It is the largest single-iron iron machine tool casting in the world. It is casted by ductile iron and molded by single casting. The tensile strength reaches 600 Mpa and above, and it has a certain elongation. Because it is an integral casting, it is stronger than the beam products that are connected. The successful casting of 135 tons of ductile iron machine tool castings is a successful attempt to adapt to the development of the domestic machine tool industry in the direction of high, large and fine, and laid a solid foundation for the high-end heavy equipment independent support.

      2, 1000 MW ultra-supercritical unit high pressure outer cylinder exhaust end
      Shanghai Honggang Power Station Equipment Casting & Forging Co., Ltd. exhibited the high-pressure outer cylinder exhaust end of the 1000 MW ultra-supercritical unit and the F-class heavy-duty gas turbine turbine bearing seat developed by independent innovation, which has got rid of the previous restrictions on import. At present, 20 pieces have been produced, of which 16 pieces have been actually used, and another 4 pieces have entered the unit assembly. The F-class heavy-duty gas turbine turbine bearing housing has been tackled for 4 years, and now its castings have also been mass-produced.

      3. Turbine blades of large hydropower stations
      Ningxia Sharing Group Co., Ltd. (hereinafter referred to as the Sharing Group) exhibited turbine blades for large hydropower stations. The casting has a weight of 26 tons, an elongation of more than 580Mpa, and a hardness of 220-285HB. The power of the unit is even higher than that of the Three Gorges unit, reaching 770 MW. After five years of research, at present, China's hydropower turbine blades have all been localized and mastered the core technology of manufacturing. The ultra-large blades of the turbine have been industrially mass-produced, and their performance and surface quality have reached world-class levels. The sharing group has provided nearly 200 super large turbine blades for the Xiangjiaba and Xiluodu hydropower stations.

      4, large bimetal centrifugal casting rolls
      Sinosteel Xingtai Machinery Roll Co., Ltd. (hereinafter referred to as Sinosteel Xingji) exhibited a large-scale bimetallic centrifugal casting roll independently developed. The casting is more than 5 meters long and weighs 72 tons. The material is a composite material of nickel-chromium alloy cast iron and ductile iron. It is the largest work roll in China. Its development has successfully broken the technological monopoly of foreign large-scale high-tech rolls to China. The independent integration capability of key components of China's steel industry is of great significance. At the same time, it has great strategic significance for China's shipbuilding and military industries, which are in urgent need of development. At present, the products of Sinosteel Xingji have been applied to the heavy plate mill of Shagang, Xiangtan and other users, and the effect is comparable to that of foreign countries.

      5, 3 MW or above large wind turbine castings
      Jiangsu Jixin Wind Energy Technology Co., Ltd. exhibited 3 MW wheel castings with the largest power generation in China. The product adopts no riser casting process, can withstand low temperature of -40 °C, and the process level and product quality have reached the world's leading level, solving the problem that large-scale wind energy components are subject to foreign restrictions.

      Second, the domestic casting equipment upgrade, highlighting the theme of energy saving, consumption reduction and environmental protection

      The domestic foundry equipment manufacturing enterprises have obviously improved as a whole, the high-efficiency static pressure molding line, energy-saving environmental protection smelting equipment, large-tonnage sand mixer and cold core box core center and other advanced casting equipment debut, showing China's casting equipment With large capacity, specialization, high precision, energy saving, environmental protection and low noise development.

      Jinan Foundry & Forging Machinery Research Institute Co., Ltd. exhibited two light-weight equipments, which are the key equipment for the cleaning production line of automobile engine block castings. It mainly carries out internal core removal and cylinder grinding on all sides, with high degree of automation, filling the domestic blank. Guangdong Yizhimi Precision Machinery Co., Ltd., Suzhou Sanji Foundry Equipment Co., Ltd., Lijin Technology (Tianjin) Co., Ltd. and other excellent die-casting equipment manufacturers are exhibiting their own featured products, including Guangdong Yizhimi Precision Machinery Co., Ltd. The 500-ton real-time control die-casting machine successfully achieved the world-class perfect injection performance, filling the gap in China's high-end die-casting machine control field.

      Casting is a high-energy, high-pollution industry, and energy conservation and emission reduction is an important task for the development of the industry. At the exhibition, new technologies, new processes and new equipment for energy conservation and environmental protection, waste recycling and utilization have received widespread attention and received favorable comments. The dual-power variable-frequency induction heating equipment developed by Suzhou Zhenwu Electric Furnace Co., Ltd., the KGPS-DX one-machine three-furnace high-efficiency energy-saving environmental smelting equipment and the high-power multi-supply smelting equipment's reactive power compensation technology have filled the domestic gap. CZS series energy-saving flexible foundry waste sand recycling technology and equipment exhibited by Chongqing Changjiang Modeling Materials Group Co., Ltd. have been widely used in the industry. At present, it can recycle hundreds of tons of foundry waste sand every year. Beijing Renchuang Technology Group exhibited a new energy-saving waste sand recycling furnace, which uses cast old sand to produce permeable floor tiles. Its products have also been widely used in the Olympic Games and the World Expo.

      In the field of foundry materials, green and environmental protection are also the development themes, degradable paper sprues, free formaldehyde content lower than the world's advanced level of resin, high-efficiency heat insulation riser and other series of casting raw materials, such as Jinan Sheng The Spring Group booth presents a green garden.
