The crystallizer is a very important part of the continuous caster.
It is a forced water-cooled bottomless copper tube mold, which is called the "heart" of the continuous caster. The mold is a continuous copper casting equipment that accepts the copper water injected from the tundish and solidifies it into a solid shell according to the prescribed cross-sectional shape. It is the most critical part of the continuous casting machine. Its structure, material and performance parameters affect the quality of the cast slab. And casting machine production capacity plays a decisive role. When pouring is started, the head of the ingot rod is the movable inner bottom of the mold. The copper water is poured into the mold and gradually condenses into a certain thickness of green shell and is continuously pulled out. At this time, the inner wall of the mold is subjected to the static pressure of the high temperature copper water. And the combined effect of mechanical stress and thermal stress generated by the friction force relative to the blank shell, and its working conditions are extremely harsh

In continuous casting, low corrosion resistance often occurs, which directly leads to uneven composition and will eventually affect the smelting quality. In or
