Furthermore, a plurality of second separation sheets are arranged in the water outlet cavity, the second separation sheets are perpendicular to the first separation sheets, the second separation sheets are used for further separating the grid cavity into small grid cavities, and each small grid cavity is communicated with one water outlet joint. The pipeline diverter is provided with more water outlets, so that more pipelines can be connected, more cooling pipes are provided, the cooling of the steel furnace is more uniform, the cooling effect of steel making can be effectively guaranteed, and the heat radiation of the steel furnace to the outside is reduced.

Further, the number of water inlet joints is smaller than the number of water outlet joints. The water inlet joint is connected with the main pipeline, the water outlet joint is connected with the cooling pipe, and the pipe diameter of the main pipeline is larger than that of the cooling pipe, so that the main pipeline is conveniently divided, and the number of cooling branches can be effectively increased.

Compared with the prior art, the utility model discloses the water yield that can every water connectors of accurate control makes the flow in every cooling tube unanimous basically to solved because of cooling water volume is inhomogeneous in the cooling tube, and leaded to the too high problem of steelmaking furnace local temperature, through the even cooling to the calculation of main line flow and can effectively realize the steelmaking furnace, can effectively improve the operational environment of casting shop. And the utility model discloses simple structure, manufacturing cost is lower, is convenient for set up.
