[History of Haichuan Pipeline] The first hot-rolled seamless steel pipe on October 27, 1953
Thread Content
CCTV news: The steel industry is the foundation of modern manufacturing and is considered * * cornerstone of industrialization. Since the founding of New China, from the birth of the first seamless steel pipe to becoming the world's largest steel producer, New China's steel industry has created many firsts through independent innovation, completely realizing my country's leap into a steel power. In 1948, Anshan, Liaoning Province was liberated, and Anshan Iron and Steel was rebuilt in the same year. The first key industrial construction project after the founding of the People's Republic of China was Anshan Iron and Steel's "three major projects" consisting of the No. 7 blast furnace, a large steel rolling mill and a seamless steel pipe factory. Gu Shengzhang, who is 88 years old this year, has worked at Anshan Iron and Steel Seamless Steel Pipe Factory all his life. The birth of the first seamless steel pipe in New China is still fresh in his memory. In the early morning of October 27, 1953, almost all the workers came to the factory in advance. At 2:30 in the afternoon, the whistle for hot trial rolling sounded, and the workers on the operating platform took their places. A bright red steel billet rolled out of the high-temperature heating furnace in charge of Gu Shengzhang, and passed through the punching machine. When the head of the cold-cut steel pipe was slowly exposed, everyone present cheered.
The commissioning of Anshan Iron and Steel Seamless Steel Pipe Plant ended the history of my country being unable to produce seamless steel pipes. It only took 1 year and 3 months from the groundbreaking of the factory to the emergence of the first seamless steel pipe. In the second year after it was put into operation, boiler pipes, geological pipes, oil pipes and stainless steel pipes were trial-rolled. The successful piercing and rolling of stainless steel pipes on a two-roller cross-rolling piercing machine is a major event in the history of seamless steel pipe production in my country, which has played a leading role in the future production of stainless steel pipes in my country.
In October 1958, Dalian Steel Plant (now part of Northeast Special Steel Group) used a seamless steel pipe unit designed and manufactured by my country to produce my country's first high-quality alloy steel seamless steel pipe.； In 1959, together with Beijing Iron and Steel Institute (the predecessor of University of Science and Technology Beijing), we trial-produced hot-rolled bearing steel pipes. At the same time, the cold drawing processing of stainless steel seamless pipes was successfully tested in the sixth section of the steel wire workshop of Dalian Steel Plant, and the production of alloy seamless steel pipes at Dalian Steel Plant began.
In 1960, Yin Guomao returned to China after completing his studies.* * He was given the important task of building the Chengdu Seamless Steel Pipe Factory. Faced with difficulties, he rose to the challenge. There are seniors above and young below. Even though the family needs him, he still responds. * * Called upon, he resolutely rushed to Chengdu. From then on, his fate was closely linked to Chengdu Seamless Steel Pipe Factory. The construction of Chengdu seamless steel pipe factory is * * Decided in 1958. Utilizing Hungary's three sets of main pipe rolling equipment (Φ133mm pipe jacking unit and Φ216, 318mm periodic pipe rolling unit), my country has independently designed, manufactured and constructed a fully-equipped independent professional large-scale seamless steel pipe factory from the production of tube blanks to the delivery of finished seamless steel pipes (including geological, oil well pipes, etc.). Chengdu Seamless Steel Pipe Factory is the first factory in my country to produce special steel seamless steel pipes. During the 40 years of working in the Chengdu Seamless Steel Factory, Yin Guomao led the team to gradually develop and expand the Chengdu Seamless Steel Pipe Factory, and China's seamless steel pipe industry has gradually grown from weak to strong. On December 31, 1965, Yin Guomao and his team overcame many difficulties and finally rolled the first large-diameter seamless steel pipe in New China with a specification of 168 mm × 7 mm. During years of practical exploration, Yin Guomao and his team members also jointly developed the "Heavy-load Rubber Elastic Safety Coupling", which won the 1985 * * Second prize for the Invention Award. The technical and economic indicators of this invention are at the world's leading level, and it has also obtained patents from five countries. Regarding these, Yin Guomao just said lightly, "I just did what the times gave me to do. If it were others, I would do the same."
At that time, the seamless pipes were mainly used for gun barrels and barrels?
Not crooked floor boiler pipes, geological pipes, oil pipes and stainless steel pipes.
These seamless steel pipes later provided steel pipes for the fertilizer industry.
I will never forget the first time I learned about seamless steel pipes in the movie Long Live Youth. At the Spring Festival Gala, Yang Qiangyun shouted about seamless steel pipes, and the audience shouted "Anshan". It seems like it was yesterday, I remember that movie theater at that time. Now I see that there is real historical evidence.
