Tongyu Heavy Industry Co., Ltd.

The company is a state-controlled listed company and a national high-tech enterprise. It is a comprehensive R&D and manufacturing platform integrating smelting, forging, casting, welding, heat treatment, machining, and coating. It has established a strategic development orientation of "building a world-class supplier of high-end equipment and new energy" and a "1122" strategic layout of "one aviation (aerospace), one high-end (high-end equipment), two seas (overseas and offshore engineering), and two new (new energy and new materials)". It can provide core components of large-scale high-end equipment for industries such as energy and power (including wind power, hydropower, thermal power, and nuclear power), petrochemicals, ships, offshore engineering equipment, metallurgy, aerospace, mining, and cement. (1) Wind power products remain the company's main product type. Relying on its comprehensive R&D and manufacturing platform advantages, the company can simultaneously provide forgings, castings, and structural components for onshore and offshore wind turbine generators of doubly-fed, direct-drive, and semi-direct-drive types in large quantities. The main product forms include wind power forged main shafts, cast main shafts, hubs, frames, bearing seats, rotor casings, stator frames, etc. In December 2024, the company's first 14MW large-scale offshore wind turbine rotor housing product was successfully launched at the Qingdao base, adding a new piece to the company's wind power product portfolio and further promoting the development of its overseas market and offshore wind power business. (2) The cast steel business has achieved high-quality development. In 2024, the company established a cast steel division, integrating existing workshops, equipment, and personnel to build a cast steel production line. It recruited talents and formed a technical team with rich experience in the research and development of large-scale high-end cast steel parts, achieving production and benefits in the same year. It provides customers with integrated services including casting, precision machining, and assembly of large-scale cast steel parts for high-end equipment. The market covers large-scale high-end equipment fields such as energy equipment (hydropower, nuclear power, thermal power, gas power, energy storage, etc.), offshore oil and gas, mining machinery, and metallurgical machinery. The product materials include stainless steel, heat-resistant steel, high-strength steel, low-temperature steel, etc., with the maximum production capacity of a single cast steel part reaching 150 tons. Currently, the company has provided products to the three major power enterprises in China and successfully "exported" cast steel products. It has obtained orders for the high-pressure outer cylinder of the conventional island steam turbine in the Bailong and Haiyang nuclear power projects and has become a supplier of cast steel parts for nuclear power steam turbine outer cylinders, marking a further enhancement of the company's large-scale high-end cast steel manufacturing capabilities and its global first-class competitiveness. (3) The nuclear equipment business enhances the company's capability in the R&D and manufacturing of complete sets of equipment. Relying on its comprehensive R&D strength and industrial chain advantages, the company has entered the nuclear equipment manufacturing field. Since the "integration of national and civilian sectors", it has continuously provided nuclear-related complete sets of equipment that can be used in various working conditions for China Nuclear Engineering Corporation, China Nuclear Power Research and Design Institute, and China Nuclear Industry Fourth OAP, etc., becoming a qualified supplier of China National Nuclear Corporation and receiving honors such as a 4A-level supplier of China Nuclear Engineering Corporation and a top ten supplier of the Second Project Department of China Nuclear Engineering. The company's nuclear equipment division is mainly responsible for the R&D and manufacturing of nuclear-related high-end equipment products, covering marketing, design, technology, quality, and after-sales services. It has completed products such as the high-level radioactive waste hot cell transfer device (hot cell crane), the low and intermediate-level radioactive waste hot cell external transfer system, and the hoisting and installation tools for nuclear power plant main equipment and auxiliary equipment in cooperation with China Nuclear Engineering Corporation, and the high-efficiency solidification production line for boron-containing waste liquid in cooperation with China Nuclear Power Research and Design Institute. (4) The structure of other forging businesses has been upgraded. The company's other forging products are diverse, covering various types of forgings such as shafts, cylinders, and gear rings. The main product forms include marine shafting forgings and hydropower unit forgings, which are widely used in the shipbuilding, power, metallurgy, mining, chemical, and heavy machinery industries. In terms of marine forgings, the main product forms include large-scale marine shafting and rudder system forgings, such as intermediate shafts, propeller shafts, rudder stocks, rudder pins, crankshafts, etc. The company has successively obtained factory approval certificates from nine classification societies including China CCS, France BV, Lloyd's Register (LR), Norway DNV, American Bureau of Shipping (ABS), Japan NK, Korea KR, Italy RINA and Russia RS. It has extended its marine forging business to the vast overseas market. Besides providing conventional products such as rudder stocks and rudder pins, it is also committed to meeting the diversified and personalized demands of customers and customizing special-shaped forgings and other cutting-edge products. Over the years, the company has closely followed the high-end, intelligent and green development trends of the shipbuilding industry, continuously optimizing the manufacturing capabilities and product structure of marine products. The orders for marine forgings have maintained a stable growth, and the marine transmission shaft products have successfully made it to the list of the eighth batch of single-champion enterprises in manufacturing released by the Shandong Provincial Department of Industry and Information Technology. In the field of hydroelectric forgings, the company can produce key core components of hydroelectric units such as turbine shafts, generator shafts and yoke rings. By leveraging the advantages of the industrial platform, it has seized the historical opportunity of the country's vigorous development of hydropower resources and continuously developed new hydroelectric unit supporting products.
