continuous casting machine and Their Characters

Currently, there are many types of continuous casting machines and methods. And, each of them has the specific characters.

continuous casting machine and Their Characters

Today, Judian will introduce the different types of continuous casting machines and their characteristics.

The continuous casting production process has specific requirements for the equipment:

The equipment must be able to handle the high temperature molten steel as it changes from liquid to liquid-solid and back to solid.

The equipment must have high temperature resistance, fatigue resistance, and sufficient strength.

The installation process should be simple and easy to operate. The equipment should be easy to maintain and replace, and should have adequate cooling and good lubrication.

There are several types of continuous casting machines:

This type of machine has even cooling of the casting shell and is not affected by bending and straightening. It is not suitable for producing internal and surface cracks and is conducive to the floating of inclusions. However, it has a large height, inconvenient operation, high investment cost, and difficult maintenance and accident handling. It also has limitations on slab section, fixed length, and pulling speed, and the slab may experience deformation due to the large hydrostatic pressure of the molten steel.

Vertical bending type continuous casting machine:

In this type of machine, the casting and cooling process is completed in the vertical direction. After solidification, the billet is bent by 90° and unloaded in the horizontal direction. This machine has a lower height compared to the vertical type, making it convenient for transportation. It can meet the requirements of longer fixed length. However, the addition of bending and straightening processes can cause cracks.

Single-point straightening arc continuous casting machine:

This machine has a lower height compared to the vertical and vertical bending types. It is lightweight, has a low investment cost, and is easy to install and maintain. The static pressure of molten steel on the slab is small, reducing the occurrence of inner column and segregation. It also allows for increased drawing speed and improved slab quality. However, during the solidification process, non-metallic inclusions tend to concentrate in the arc, resulting in uneven distribution of impurities inside the slab continuous casting machine and Their Characters.

Multi-point straightening arc continuous casting machine:

This machine combines the advantages of the vertical type and allows for the floating of large inclusions and even distribution of inclusions in the steel. It has a higher height compared to the vertical bending type, but lower construction cost continuous casting machine and Their Characters.

Oval continuous casting machine:

This machine has strict requirements for the molten steel as the inclusions in the mold have almost no chance of floating.

Horizontal continuous casting machine:

This machine is simple to maintain and handle accidents. However, the separation between the tundish and the mold is expensive, and lubrication between the mold and the billet is difficult.

This concludes our knowledge sharing about continuous casting machines. We hope it has been helpful to you. Welcome to Luoyang Judian, where we can provide you with more services.
