What kind of continuous casting machine is used to divide the continuous casting machine?

1 ) Vertical continuous casting machine, vertical bending continuous casting machine, curved continuous casting machine, elliptical continuous casting machine and horizontal continuous casting machine.

2 ) A , vertical continuous casting machine: advantages: the casting machine shell cooling is uniform, and is not subject to bending straightening, so it is not suitable to generate internal and surface cracks, which is conducive to the inclusions floating; disadvantages: the equipment is high in height, operation is not Convenience, high investment cost, equipment maintenance and accident handling are difficult, the billet section and fixed length and pulling speed are limited, and the slab has a large static pressure due to molten steel, and the slab femoral deformation is more prominent.

B , elliptical continuous casting machine: advantages: the height is greatly reduced compared with the arc, the static pressure of molten steel is low, the amount of strands of the casting blank is small, the center segregation of the internal crack is improved, and the investment saves 20%—-30% (specific arc shape). Disadvantages: The inclusions in the molten steel in the crystallizer have almost no floating opportunities, so the requirements for molten steel are strict.

1. Horizontal continuous casting machine: Advantages : It is the lowest equipment height, the secondary oxidation of molten steel, the quality of slab is improved, it is not affected by bending and straightening, it is beneficial to prevent cracks, the equipment maintenance is simple, and the accident handling is convenient; The separation between the package and the crystallizer is relatively expensive, and the lubrication between the crystallizer and the cast slab is difficult. The crystallizer does not vibrate during the drawing, and is suitable for small blanks, various castings, billet of 200 mm or less, round billet, special steel.

D , curved continuous casting machine: divided into single point straightening arc continuous casting machine, multi-point straightening arc continuous casting machine, straight crystal mold continuous casting machine.

a ) Single-point straightening arc continuous casting machine: Advantages: the height is lower than the vertical type and the vertical bending type, so the equipment is light in weight, low in investment cost, convenient in installation and maintenance, and the static pressure of molten steel on the casting blank is small, which can reduce the cause The inner column and segregation caused by the femoral belly are beneficial to improve the speed of the casting and improve the quality of the slab. Disadvantages: During the solidification process of molten steel, non-metallic inclusions have a tendency to focus in the arc, which results in uneven distribution of debris inside the casting blank.

b ) Multi-point straightening arc continuous casting machine: Advantages: When the solid-liquid interface deformation rate is reduced, the liquid core is straightened without internal cracks, which is beneficial to increase the pulling speed.

c ) Straight crystallizer curved continuous casting machine Advantages: It has the advantages of vertical type, which is conducive to the floating of large inclusions and the average distribution of inclusions in steel. It is higher than the vertical bending height and low construction cost. Disadvantages: The outer shell of the casting blank is stretched, and the two-phase area is easy to cause crack defects. The equipment structure is complicated, and it is difficult to repair and repair.
