There are two types of crystallizers according to the linear division of the inner wall of the section in the direction of casting: curved and straight; According to its overall structure, there are both sleeve and combination types for both curved and straight shapes.

The cooling water jacket composed of inner wall copper pipes, inner and outer water jackets, and foot rollers are its main components. The outer surface of straight or curved copper pipes consists of cooling water jackets, flanges, and sealing elements, forming a water supply and oil supply system. In order to ensure a regular appearance of the billet, 2-3 sets of foot rollers are installed at the bottom of the mold to improve the casting speed and prevent the billet from falling off square.

A crystallizer is a continuous steel casting equipment that receives molten steel injected from the intermediate tank and solidifies it into a solid shell according to the specified cross-sectional shape. It is the most critical component of the continuous casting machine, and its structure, material, and performance parameters play a decisive role in the quality of the casting billet and the production capacity of the casting machine.
