China Has Developed A Heavy-duty Extrusion Machine Tool For The Production Of Large-scale Titanium Alloys

China has developed a heavy-duty extrusion machine tool for the production of large-scale titanium alloys

The heavy-duty extruder for hard-to-deform metal is a great tool for the production of high-performance metal materials. Since China has conquered this key equipment, it has continuously refreshed the world record for this equipment.

In the past, due to the lack of heavy-duty squeezers for hard-to-deform metals in China, many high-performance metal materials relied on imports, which restricted the development of domestic high-end equipment. To this end, Beizhong Group decided to introduce a 36,000-ton vertical extruder. At that time, only the American Weiman Gordon Company mastered the heavy-duty extrusion technology of hard-to-deform metals and had a 31,500-ton vertical extruder. Beizhong Group held negotiations with Weiman Gordon, and the other party said: “This technology is their unique core technology and is not transferred to the outside world. “Beizhong Group also asked Simak, a German machinery and equipment manufacturing company. Simak said: "They have studied this technology and they can manufacture it." ”But the offer is very expensive. Finally, Beizhong Group decided to independently develop a 36,000-ton vertical extruder.

After three years of hard work and an investment of 990 million yuan, Beizhong Group broke the long-standing exclusive technology monopoly of Weiman Gordon, and surpassed American companies in technology, and developed the world's largest 36,000-ton vertical extruder at that time. The cost of this machine tool is equivalent to one-third of the price quoted by German companies.

Beizhong Group uses a 36,000-ton vertical extrusion machine to manufacture high-temperature and high-pressure large-caliber thick-walled seamless steel pipes. This kind of steel pipe is widely used in power stations, metallurgy, chemical industry and other fields. This kind of steel pipe used to rely on imports for a long time. After the localization of this kind of steel pipe, the price of similar foreign products has dropped from more than 100,000 yuan per ton to tens of thousands of yuan.

Beizhong Group also uses a 36,000-ton vertical extrusion machine to manufacture large-scale powder superalloy bars, which are used in the manufacture of high-pressure turbine discs for aviation engines. Beizhong Group is the third company in the world to be able to produce this kind of bar after Weiman Gordon in the United States and Aberduwa in France. In addition, the 36,000-ton vertical extruder can also manufacture large-caliber titanium alloy pipes for submarines and deep submersibles.

Subsequently, domestic companies set a new record and manufactured a larger 50,000-ton vertical extruder. Hongrun Nuclear Equipment used up almost all the company's funds and spent 500 million yuan to develop a 50,000-ton vertical extruder.

This 50,000-ton vertical extruder is the press with the largest opening in the world. The opening height of this extruder reaches 8.5 meters, and the work surface size is 3.8 meters by 6.8 meters. This 50,000-ton vertical extruder can be extruded or die-forged. It can squeeze steel pipes with an outer diameter of 1.32 meters, a length of 13 meters, and a weight of 30 tons. It can also die-forge metal forgings with a size of 3.5 meters and a weight of 50 tons.

Hongrun nuclear's 50,000-ton vertical extruder has played a key role in the field of nuclear power, manufacturing nuclear power main pipelines, nuclear power main pump housings, valve bodies, etc. Hongrun nuclear equipment also used a 50,000-ton vertical extrusion machine to manufacture the world's largest marine diesel engine crank. This large crank used to rely on imports, and Hongrun nuclear equipment's crank can replace imported products.

After that, Chinese companies set records again. It took 5 years and spent more than one billion yuan to develop the world's first 68,000-ton multi-function extrusion die forging press. This machine tool has extrusion and die forging functions, and its hot extrusion capacity ranks first in the world.

China Titanium Qing Forging used this machine tool to manufacture the world's longest vertical extruded steel pipe, the world's largest diameter extruded titanium pipe, and the longest high-strength aluminum alloy seamless pipe in China.

The titanium alloy parts of the suspension system manufactured by this machine tool for a certain type of combat vehicle are 43% lighter than the original product, and the anti-corrosion and fatigue properties are increased by 30%. This machine tool also makes hollow shafts for aircraft engines for Shenyang Institute of Materials Research.
