What is the principle of mold design for efficient continuous caster?

(1) Ensure the high efficiency of heat conduction function, that is, the cooling intensity is large, the cooling efficiency is high, so that the billet in the mold crust to reach enough thickness;

(2) The heat flow strength of mold is uniform.  Uniform heat flow strength, not easy to produce organizational stress, so that the generated billet shell uniform;

(3) the blank resistance is small;

(4) Long life of crystallizer, especially copper tube.

At present, the square mold mainly adopts parabolic copper pipe and refined copper water jacket technology.  The inner cavity shape of the mold copper tube should be as close as possible to the solidification characteristic curve of the billet shell, and the water jacket should ensure enough dimensional accuracy to ensure the uniformity of water joints.  High efficiency caster mold is usually equipped with electromagnetic stirring and liquid level control device.
