Steel Continuous Caster Types and Their Characters

Luoyang Judian is a manufacturer of rolling equipment, including steel continuous caster, rolling mill, and so on. In the steel rolling production line, there is some information about the equipment, which I would like to share with you today.

The first is the determination of the continuous casting machine. The common continuous casting machines have the following types.

Vertical Steel Continuous Caster

The billet shell of the casting machine is cooled evenly and is not subject to bending and straightening, so internal and surface cracks are not suitable.

However, the height of the equipment is large, the operation is inconvenient, the investment cost is high, and the equipment maintenance and accident handling are difficult.

The section of the slab, the fixed length and the drawing speed are limited, and the slab groin deformation is prominent due to the large hydrostatic pressure of the slab.

Vertical Steel Continuous Caster

Oval Caster

Compared with the arc, the height is greatly reduced, the static pressure of molten steel is low, the amount of cast billet is small, the segregation of the internal crack center is improved, and the investment is saved by 20%-30%.

However, the inclusions in the molten steel in the mold have almost no chance of floating, so the requirements for the molten steel are strict.

Horizontal Caster

The height of the equipment is low, the molten steel is oxidized twice, the quality of the casting billet is improved, and it is not affected by bending and straightening, which is conducive to preventing cracks, simple equipment maintenance, and convenient accident handling.

However, the separation between the tundish and the mold connection is expensive, the lubrication between the mold and the billet is difficult, the mold does not vibrate when the billet is drawn, and is suitable for small billets, various castings, square billets below 200mm, round billets, and special steel.

Then let's take a look at the effect of molten steel temperature.

When the temperature is too high, the corrosion of the molten steel to the refractory material is accelerated, which is easy to cause the control of casting loss and reduce the safety of casting. It will also affect the quality in the slab;

When the molten steel temperature is too low, it is easy to block the nozzle, resulting in the interruption of casting. Scarring, slag inclusion, and crack equation defects are prone to occur on the surface of the billet, which affects the quality of the inclined billet.

This is what we share today, I hope it can help you. Welcome to Luoyang Judian for more information.
