At present, continuous casting machines have been widely used in steel mills, with various forms and different uses. The name of the continuous casting machine is also very inconsistent. Now introduce the classification method of continuous casting machine according to general habits:
(1) The appearance classification of continuous casting machine includes: vertical continuous casting machine, vertical bending continuous casting machine, arc continuous casting machine, ultra-low head (elliptical) continuous casting machine, horizontal continuous casting machine, wheel continuous casting machine Wait.
(2) According to the cast slab section classification:
-Billet continuous casting machine: The section is less than or equal to 150×150mm called billet, and larger than 150×150mm is called bloom. In billet continuous casting, 120×120mm is used as a dividing line. Above this value, immersion nozzle and mold slag are used for pouring, and below this value, open pouring or gas-protected pouring is used. If the ratio of the long side to the wide side of the rectangular section is less than 3, it is also called a billet continuous caster.
-Slab continuous caster: the section of the cast slab is rectangular. The width-to-thickness ratio is generally above 3.
-Round billet continuous casting machine: the section of the cast billet is circular, with a diameter of Φ60~Φ400mm.
-Special-shaped billet continuous casting machine: Pouring special-shaped sections such as I-beams.
-Continuous casting machine for both square and slab: On one casting machine, both slab and square billet can be poured.
SHENGMIAO can produce mold copper tubes of different sizes for different types of continuous casting machines.
Square copper mould tube,150*150; 130*130; 120*120; 100*100; 90*90; 80*80;
Rectangular Copper mould tube,
Round Copper Mould Tube.
(3) According to the drawing speed classification, there are: high drawing speed continuous casting machine and low drawing speed continuous casting machine. The main difference between them is that the casting slab is straightened with liquid core at high drawing speed, and the casting slab is fully solidified and straightened at low drawing speed.
(4) According to the classification of the hydrostatic head of the steel: the high-head type continuous casting machine with higher static pressure is called the vertical type continuous casting machine and the vertical bending type continuous casting machine. The lower static pressure is called the low-end continuous casting machine, such as the arc, ellipse, and horizontal continuous casting machine.

In continuous casting, low corrosion resistance often occurs, which directly leads to uneven composition and will eventually affect the smelting quality. In or
