Published on 2018-03-27

Shanghai electric group wuxi turbine blade co., LTD. (WTB) allows went into operation imported 35500 tons of high energy screw press.More than 100 35500 tons of energy and aviation industry experts live to witness the screw press in three hours to replace the three pairs of mold, the perfect finish plate, sheet, frame three problem forging process of the product.It marks the WTB toward world-class large blade and aviation forgings allows manufacturers a step closer, also means that our country will further enhance the ability of expertise in manufacturing plant leaves.

surge forging production capacity of

reported that 35500 tons of high energy screw press is by far the world’s most advanced, the largest one of the two screw press, can be in brief contact with the workpiece forming metal products, a huge blow to force the largest force can achieve 35500 tons, its craft is a combination of forging hammer and hydraulic press, the advantages of both leaves and aircraft, aviation engine is the realization of power station and the high performance of special steel, titanium and nickel base superalloy class structure products are the ideal choice.
,
, expert says, compared with the traditional screw press, the device adopts a new type of clutch not only make the press forming energy increased significantly, still can reduce about 87% of the energy consumption, is worthy of the name “high-energy” equipment with high efficiency.The impact velocity of the press in the 0.25 0.5 m\/SEC, forging adjustable stroke between controllable variable, blow energy;Compared with the previous press and hammer, it can produce better metallurgical quality, organizational performance is more uniform, more accurate size of large forgings.The equipment with 3150 tons of free forging press, more than 8 meters gas rotary hearth furnace and of large electric furnace, provide the flexibility to meet the nuclear power, gas turbine, aviation, aerospace, military industry and other fields evolving needs.

WTB general manager allows YanJi, said it was for the nuclear power energy and aviation military expansion of the forging of strategic considerations, WTB started planning 3 – allows the construction of the screw press, in order to meet the aviation forgings, nuclear power large leaves and the market demand.Shanghai electric (group) corp CEO di-nan huang believes that the introduction of the press machine, is an important milestone of WTB towards a world-class factory allows, is lit sustainable development power, create world-class brand engine, at the same time for China’s electric power equipment and aviation forging industry development has the vital significance.

can meet the needs of nuclear power very large blade production
,
, China forging association secretary-general gold, said China is already the world’s superpower forging, but not forging press power.China will become stronger in the world in forging industry, technology introduced from abroad advanced equipment may be necessary, but the introduction is just a tool.On the basis of the introduction, digestion, absorption and innovation, developed with China’s independent brand equipment should be our goal.
,
, as we have learned, the introduction of 35500 tons of high energy screw press is the core of WTB implementation of “strategic expansion projects” allows a ring, but also an important deployment of WTB strategic transformation allows.Plant leaves as a company with over 30 years of industry practice professional manufacturing enterprises, since 2006, WTB based on national energy and allows the response of the aviation industry development strategy, through in-depth analysis of the power station equipment and aviation forging industry, research, and will have to develop the field of nuclear energy and air defence forging strategic considerations, WTB nuclear ci big leaf, gas unit allows large leaf blades, clean and efficient thermal power units and air defence components four categories of products as the focus of new and high technology industrialization development areas, 3 – and start planning for the construction of the screw press, to meet the market demand of nuclear power large blades and aviation forgings;Outside the “blade specialization manufacturing”, focus on the development of “to the aviation industry as the leading specialized in forging manufacturing” ability, form two specialized common development of the new model, the construction of advanced focus, major equipment and key components of the core parts manufacturing capability, formed in the plant leaf and aviation forging industry indispensable core strengths.
,
, it is in this strategic thought, under the lead of WTB since 2007, allows successively organized by the power station and aerospace industry experts to participate in the strategic development of key equipment selection and expert consultation, forging technology development research activities for many times, more than 30 units of more than 60 scholars, experts, to participate in, to help the WTB constantly optimized, allows perfect strategic development planning, key equipment ultimately chose Germany SMS Meer company SPK22400 new type clutch screw press and the corresponding auxiliary equipment, and in August 2008 formally signed import contract.

reported that
tons of high energy screw press 5800 tons, the total weight including base parts including monomer maximum weight of 340 tons, nearly 10 single parts weigh more than 100 tons.SMS Meer company experts, WTB project team and related personnel, allows the machine installation personnel WuJian company nearly hundred people participated in the equipment engineering construction projects, from October 8, 2010 press one of the first component approach, to try on May 31, 2011 forging products, lasted 236 days.Press construction after big transportation and hoisting equipment, 307 tons workbench, 345 tons of beam of large pieces of precise hoisting in place, 590 tons of the flywheel clutch assembly, debugging of electrical system, hydraulic system key node;Solves the special tools manufacture in the installation, 345 – ton beam roll over, overall framework is installed and loaded prestressed technical problems such as the laser measurement.Try forging products from May 31 to formally put into production in just 10 days, 10 days WTB engineering technicians and forging allows workers to overcome the difficulties, has completed more than on the pressure machine technology development and trial production process of the product.Based technology such as
,
, look forward to forging

composed of forging, stamping and sheet metal forging industry is the foundation of the equipment manufacturing industry, its forming parts are widely used in electric power, petrochemical and other industries, is a machinery and equipment of the main bearing structure or bearing structure, quality and safety to the host plays a decisive role.
,
, according to introducing, in the field of energy, cannot produce some domestic large-scale equipment and components to a certain extent is limited by forging technology.Therefore, to fundamentally improving the capacity of our energy equipment development, forging as the foundation technology must be improved.
,
, at present, the gap between domestic forging industry and abroad mainly in fine manufacturing, low labor productivity, the die life is shorter, etc.

experts told reporters that forging production in China has long been in a state of extensive, with low energy consumption, high material utilization, serious environmental impact as the main characteristics.At present, in order to adapt to the direction of sustainable development, puts forward higher requirements on precision forming technology, the rapid development of a large number of high-quality, high efficiency, energy saving, energy saving of the plastic forming technology, realize the industry’s dream “net forming” the goal is the main development direction.

now, forging industry should take advantage of existing conditions well technology development, product improvement, talent introduction and other important work.To give full play to existing resources, to promote industry merger and reorganization, spontaneous realize combination;Forging enterprise should as far as possible with the same has close ties to strategic partners.At the same time, further strengthen enterprise cooperation with scientific research institutes.Only in this way, to improve the overall technology level of forging industry in our country, provide better service for the equipment manufacturing industry.
