Steel rolling workpiece cooling device

Abstract

The invention discloses a steel rolling workpiece cooling device, and belongs to the technical field of steel rolling cooling equipment. The steel rolling workpiece cooling device is used for coolinga steel rolling workpiece, according to the technical scheme, a base is arranged below a steel rolling conveying belt, two side protecting plates are located on the two sides of the steel rolling conveying belt respectively, the lower ends of the two side protection plates are vertically connected with the base, the upper ends of the two side protection plates are connected with the bottom of thewater tank, a plurality of drainage grooves which are arranged in parallel and are discharged downwards are formed in the steel rolling conveying belt between the two side protection plates, the innerwall of the base is fixedly connected with a flow guide tank, the upper end of the flow guide tank is opposite to a drainage groove in the steel rolling conveyor belt, the bottom of the flow guide tank is fixedly connected with the upper end of the water storage tank, the bottom of the water storage tank is connected with the water pump, the water pump is connected with the water tank through a water delivery pipe, a plurality of cooling pipes are arranged on the bottom surface of the water tank, and a plurality of high-pressure atomizing nozzles are respectively arranged on the cooling pipes. So that the quality of the product is ensured, the cooling water can be recycled, so that the utilization rate of the cooling water is improved.

Description

technical field [0001] The invention relates to a cooling device for steel rolling workpieces, belonging to the technical field of steel rolling cooling equipment. Background technique [0002] The steel rolling method can be divided into hot rolling and cold rolling according to the rolling temperature, and can be divided into longitudinal rolling, horizontal rolling and skew rolling according to the relative motion relationship between the rolled piece and the roll during rolling. Divided into general rolling and special rolling, cycle rolling, spinning rolling and bending forming are all special rolling methods. The hot-rolled steel sheet after the finish rolling step in the hot rolling process is cooled to a predetermined steel sheet temperature by a cooling device having a plurality of cooling machines while being transported from the finish rolling mill to the coiler, and then coiled by the coiler . In hot rolling of a steel sheet, the state of cooling from the finis...
