Shougang Mould Copper Tube Longevity Technology Achievement Passes Identification

The “Longitudinal technology of continuous casting billet crystallizer copper tube” jointly developed by Shougang Dongxing (Group) Corporation and the Technology Research Institute, the Second Steelmaking Plant, and the Third Steelmaking Plant passed the Beijing Municipal Commission of Science and Technology in September 2003. Identification of the results of the organization.
The life of continuous casting billet crystallizer copper tube is directly related to the efficiency of continuous casting production and the quality of billet. Dongxing Company has made bold innovations in the design and manufacture of mold copper tubes, copper tube plating, etc., which has greatly improved its firmness, uniformity and wear resistance, and has created conditions for increasing the life of crystallizer copper tubes. .
The mold copper tubes produced by East Star (Group) Company were tested in industrial applications at the second steelmaking plant: the service life of the 120 square copper tubes was increased by 68.9%; the tests at the third steel plant showed that: 130 square copper tubes The service life is 439 furnaces/branch, the average steel quantity is 4390 tons/piece, the average drawing length is 34180 meters/piece, and the qualified rate of the produced billet is 99.5%. The conclusions reached by the test manufacturer indicate that this kind of crystallizer copper tube can be widely used.
