Design principles of efficient continuous casting crystal device assembly

What is the principle of the crystallization device design of the efficient continuous casting machine?

(1) Ensure high efficiency heat transfer function, that is, the cooling strength is large, the cooling efficiency is high, so that the billet in the crystallizer to reach enough thickness;

(2) The thermal flow strength of the crystallization is uniform. The heat flow strength is uniform, not easy to produce tissue stress, so that the generated cast billet shell is uniform;

(3) drag resistance is small;

(4) Crystallizers, especially copper tubes, have a long life.

At present, the blank crystallizer mainly adopts parabolic copper pipe and refined copper water sleeve technology. The inner cavity shape of the crystallizer copper tube shall be as consistent as possible with the solidification characteristic curve of the blank shell, and the water sleeve shall ensure sufficient dimensional accuracy to ensure the uniformity of the water joint. High-efficiency even casting machine crystallizers are generally equipped with electromagnetic mixing and liquid surface 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
