[Yellow River Anlan] Kneading steel groups and building "underground cities" How great are the "important weapons of the country" on the banks of the mother river?

　　China News Service, Zhengzhou, September 19th (Kan Li) The 10,000-ton hydraulic press "kneads dough" to forge giant forgings, and the shield machine with a diameter of more than 10 meters goes into the ground to develop underground space... These are huge and unimaginable for ordinary people. "Heavy equipment" work scene.

　　Recently, a reporter from Chinanews.com visited CITIC Heavy Industry Machinery Co., Ltd. (hereinafter referred to as CITIC Heavy Industry) and China Railway Engineering Equipment Group Co., Ltd. (hereinafter referred to as China Railway Equipment) in Luoyang, Zhengzhou and other places with the interview group of the "Yellow River Anlan" network theme event. , Zhengzhou Coal Mining Machinery Group Co., Ltd. (hereinafter referred to as Zheng Coal Machinery), on-site visits to understand the arduous and innovative road of many "national heavy weapons", and the Yellow River spirit of pioneering and hard work behind it.

　　In the forging workshop of CITIC Heavy Industry, after the red ingot is "kneaded" by a giant hydraulic press, giant pliers transport the formed forging to the designated area.

Standing outside the work area, the bursts of heat blowing from the face make people dare not approach.

The picture shows that the giant hydraulic press in the forging workshop of CITIC Heavy Industry is producing castings.

　　This hydraulic press has a height of 20 meters above the ground, a depth of 7.5 meters underground, a movable table of 5.4 × 13 meters, a maximum upsetting force of 18,500 tons, and a weight of more than 4,000 tons.

　　The operator of this "giant" is Guo Weidong, the leader of the forging group in the forging workshop, and is also a "big craftsman" of CITIC Heavy Industry.

　　Since he started working in 1987, Guo Weidong has gradually grown into a leader in operating the core equipment of this enterprise.

Today, the company has also established the "Guo Weidong Great Craftsman Studio".

　　Over the years, Guo Weidong, who is experienced and good at research, has repeatedly completed the production tasks of the company's world-class high-end forgings.

　　In the China Railway Equipment Workshop, several workers are assembling a giant shield machine with a diameter of 8 meters. "This is going to be exported to Turkey," said a worker.

　　So, how to transport such a large shield machine?

　　"The maximum diameter is 15 meters, which is twice the size of the big guy in front of you!" Hao Luping, director of the Party and Mass Work Department of China Railway Equipment Shield Company, introduced that many such conventional shield machines are produced from the workshop every year. Disassemble the device for transportation.

　　In recent years, with the development of underground space, the use of shield machines has become more and more.

Whether it is transportation, water conservancy or coal mines, the development and construction of underground space are inseparable from the shield machine.

　　Shield machine is a high-end equipment integrating mechanical, electrical, hydraulic, sensing, information, mechanics, guidance research and other technologies.

　　In recent years, China Railway Equipment has made more innovations in shield technology.

The R&D team of China Railway Equipment has successively designed and manufactured the world's largest diameter rectangular shield machine, the world's largest diameter hard rock roadheader, the world's first horseshoe-shaped shield machine, the world's first dedicated shield machine for communication channels, and China's first 15-meter-level super-diameter machine. A large number of pioneering products such as Slurry Shield Machine.

　　Compared with the "blank" more than 20 years ago, various products of China Railway Shield have been applied in more than 40 cities in China and exported to more than 30 countries and regions such as Italy, France, Denmark, Australia, Singapore, the United Arab Emirates and Peru.

　　In the spacious, bright and high-tech exhibition hall of Zheng Coal Machinery, the reporter learned about the changes in China's coal mine fully mechanized mining technology. The development of the industry for more than 60 years.

　　Wang Yongqiang, deputy general manager of the coal machinery sector of Zheng Coal Machinery Group, introduced that the hydraulic support for coal mines with the highest support height and the greatest working resistance in the world, the first set of intelligent fully mechanized mining face supplied by a single manufacturer in China, and the first complete set of fully mechanized mining in China The export equipment is independently developed and manufactured by Zhengmei Machinery.

　　In recent years, with scientific support, excellent quality, intelligent equipment and professional services, Zhengmei Machinery's intelligent complete sets of equipment have been exported to Russia, Turkey and other countries.

　　In addition, on the basis of consolidating the existing business, the auto parts segment of Zhengmei Machinery is actively embracing the future industry, and comprehensively exploring and starting the pace of transformation to the new energy field.

　　Wang Yongqiang said that in March this year, the joint venture between Zhengmei Machinery and Sorenger China, Sorenger Automotive Electric System Co., Ltd., was officially unveiled, and Zhengmeijian took a key step in the transformation to the field of new energy drive motors.

　　At present, Zhengmei Machinery has become the world's largest supplier of fully mechanized coal mining technology and equipment, and an international leading auto parts manufacturer.
