Intermediate blank cooling system and cooling control technology

The invention belongs to the metallurgy technical field and in particular relates to an intermediate blank cooling system and cooling control technology. The intermediate blank cooling system is characterized in that an aerial fog cooling device body is arranged between a rough mill and a finishing mill. The aerial fog cooling device body is composed of an upper cooling header and a lower coolingheader, and an aerial fog nozzle and a compression air pipe are arranged on the cooling water pipe of the upper cooling header and the lower cooling header; and the on/off control valve and flow control valve of the cooling water pipe and the compression air pipe are connected with a control valve station. The intermediate blank aerial fog cooling technology is controlled by the aerial fog control technology sprayed on the cooling header arranged near roller ways at the front and rear of the mills. The invention has fast cooling speed without changing metal performance, water yield regulatingrange is wide and the water yield can be regulated continuously, the cooling speed of the intermediate blank can be precisely controlled, and the invention can be widely applicable to middle and thick plate production line.
