After more than four years of hard work, Qinghai Kangtai Casting and Forging Machinery Co., Ltd. and Tsinghua University's industry-university-research cooperation project came out. The world's first 68,000 tons of extrusion and die-forging dual-function heavy-duty presses were successfully tested. A carbon steel seamless steel pipe with a length of 12.8 meters, a diameter of 630 mm and a wall thickness of 110 mm is the world's number one in the series of vertical extruded steel pipes.
Since the "Twelfth Five-Year Plan", the province has firmly grasped the strategic opportunity of accelerating the development of traditional advantageous industries and rapidly expanding the scale of industrial economics, and actively promoted the transformation and upgrading of the equipment industry. Taking measures such as developing high-end industries, introducing foreign companies, and advancing technological innovations, and strengthening the complementarity and service guarantee relationship with the advantageous industries such as oil and gas, salt lake chemicals and non-ferrous metals in the province, and gradually forming CNC machine tools, sanitation equipment, special vehicles and Non-standard equipment is the core equipment manufacturing system.
In the first four years of the “Twelfth Five-Year Planâ€, the industrial added value of the whole industry has maintained a double-digit growth. Even in 2015, in the face of economic downturn and other pressures, it still increased by 14.1% from January to September.
Among them, the super large forging equipment has gradually seized the commanding heights of domestic and even world industrial development. 680MN multi-function die forging press unit project extrusion tonnage, is the world's first large tonnage, multi-functional integrated die forging hydraulic equipment, is the first domestic multi-functional large-scale equipment used in the forging industry. After the completion of the project, the products will cover important forgings of military and civilian large aircraft, large-sized special-shaped shaft parts and high-quality steel pipes, which will fill the gap in the production of large-diameter thermal power/nuclear power pipes and improve the design and manufacture of super-large forging equipment in China. Installation capability.
The petroleum machinery factory CYJ8—3—26HY(SW) digital pumping unit was successfully trial-produced and mass-produced, filling the blank of the production of oil production equipment in our province. The Qinghai Jieshen 5000 special vehicle modification project has been equipped with large-scale production. Capacity and development of natural gas vehicle modification business; Qinghai Dongda, Hengye equipment and other enterprises implemented 50,000 tons of heavy steel structure, non-standard equipment processing and container manufacturing, dryers and dust removal equipment and other non-standard construction projects, has formed 15 The production capacity of non-standard equipment of about 10,000 tons can basically meet the market demand in the fields of petrochemical, coal chemical, salt lake chemical and environmental protection industries in the province. Environmental sanitation equipment has formed a complete industrial chain covering garbage collection, removal and treatment systems; the micrometer has a high reputation in the country and has a certain market share in the world, and the output has accounted for more than 60% of the national total output.
