Design principles of high-efficiency continuous casting mold assembly
What is the principle of mold design for high-efficiency continuous caster?
(1) Ensure high-efficiency heat conduction function, that is, high cooling intensity and high cooling efficiency, so that the casting slab will be encrusted in the mold to a sufficient thickness;
(2) The heat flow intensity of the mold is uniform. The heat flow intensity is uniform, and the structural stress is not easy to generate, so that the resulting cast slab shell is uniform;
(3) The drawing resistance is small;
(4) The mold, especially the copper tube, has a long life.
At present, the billet mold mainly adopts parabolic copper tube and refined copper water jacket technology. The inner cavity shape of the mold copper tube should match the solidification characteristic curve of the blank shell as much as possible, and the water jacket should ensure sufficient dimensional accuracy to ensure the uniformity of the water gap. High-efficiency continuous casting machine molds are generally equipped with electromagnetic stirring and liquid level control devices.

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