Description

6 Strands R8.5 Full Arc Continuous Caster

At present,  arc continuous caster is mainly used in small square billets and round billets below 150mm. Because the crystallizer is arc-shaped, the billet drawn out is also arc-shaped. The crystallizer and the secondary cooling section are configured on the quarter arc.

Before being straightened, the billet moves downward along the arc and solidifies. It is straightened once with a five roller tension leveler in front of the vertical center tangent point.

When the billet is straightened, the inner arc extends outward and the outer arc is extruded inward. Because the five roller tension leveler is single-point straightening, in order to prevent cracks for billet breaking and internal damage, the deformation of the billet shall be controlled within the allowable deformation coefficient, and the arc radius shall be increased, which is the reason why the arc continuous caster is built.

Technical Advantages of Arc Continuous Caster

 

High Product Quality

Large radius arc continuous caster is selected as the model of a continuous casting machine, and continuous straightening technology is adopted to reduce the deformation rate of the continuous casting slab and prevent the surface and internal cracks of the slab.

 

Safe and Stable

The liquid steel level of the tundish is protected by double slag: the first layer adopts synthetic slag to isolate the liquid steel from the air and absorb floating inclusions; The second layer adopts natural slag (carbonized rice husk) to cover the synthetic slag for thermal insulation.

 

Automatic Protection Technology

Because the automatic equipment is added into the square and round billet arc continuous caster, the distribution uniformity of protective slag is realized by effectively controlling the addition speed of protective slag. In addition, the application scope of automatic protection technology also includes improving the lubrication conditions inside the mold and promoting the overall efficiency of production, so as to reduce the production risk and improve the overall profit

 

Automatic Mixing Technology

The application principle of automatic stirring technology mainly depends on electromagnetic stirring, so it reduces energy consumption. Compared with the use mode of traditional continuous caster, the electromagnetic stirrer at the end of secondary cooling also has the effect of expanding the axial crystal rate of the billet. It plays a certain role in improving the loose environment inside the billet and improving the effect of central segregation of the billet.

 

Improve Use Efficiency

In order to improve the use efficiency of equipment and reduce the operation intensity of workers, the ladle turret adopts an automatic positioning system. High speed, low speed, and parking space change-over switches can also be set on-site for manual control.

 

High Degree in Automation Control

The high degree of automation equipment reduces the production cost, improves the yield, improves the working environment of the steel plant, reduces the labor intensity of workers, and brings good economic and social benefits to the steel plant.
