Process for effectively controlling bleed-out of high-manganese high-aluminum dual-phase steel continuous casting crystallizer

The invention discloses a process for effectively controlling bleed-out of a high-manganese high-aluminum dual-phase steel continuous casting crystallizer, and belongs to the technical field of metal smelting. The process can effectively control the problem of continuous casting bleed-out, so that the blank shell is uniformly cooled, the thickness is increased, and bleed-out accidents are avoided. Compared with the prior art, by optimizing the back taper of the crystallizer, the cooling curve of the crystallizer, the casting powder and the continuous casting pulling speed, a technical guarantee is provided for effectively controlling bleed-out of the high-manganese and high-aluminum dual-phase steel continuous casting crystallizer, and bleed-out of the high-manganese and high-aluminum dual-phase steel crystallizer is reduced to 0% from original 20%. And the surface quality of the high-manganese and high-aluminum dual-phase steel casting blank is greatly improved, the loss rate of flame cleaning is effectively
