Embodiment Construction

[0021] The following will be combined with Figure 2-4 The present invention is described in detail ( figure 2 The direction indicated by the arrow above the middle steel plate 1 is the steel plate conveying direction): The steel plate uniform cooling device with curved water outlets in this embodiment includes an upper header device, and the upper header device is provided with a spraying direction perpendicular to the steel plate 1 and The spray range covers the width of the steel plate with multiple outlets, and the multiple outlets are arranged side by side along the steel plate conveying direction. In the prior art, the multiple outlets are arranged in a straight line. In this embodiment, the projection of each outlet on the steel plate is in a curved distribution. The opening direction of the curve is the same as the conveying direction of the steel plate 1 . This layout structure utilizes the characteristics of the flow field formed by water spraying at the water outl...

Abstract

The invention discloses a steel plate uniform-cooling device with water outlets arranged in a shape of curve, which comprises an upper header device. A plurality of lines of water outlets which have a jetting direction vertical with the direction of a steel plate and a jetting range which covers the width of the steel plate are arranged on the upper header device; the plurality of the lines of the water outlets are arranged in parallel in a convey direction of the steel plate; projections of the water outlets on the steel plate are arranged in the shape of curve; an opening direction of the curve is as same as the convey direction of the steel plate. The manner of the water outlets of an upper header is changed from a linear manner to a curve manner, so that used cooling water absorbing acertain amount of heat fast departs the upper surface of the steel plate along a tangential direction of a back line of cooling water wall. Therefore, the residue of the cooling water on the edges isreduced; meanwhile, the device provided by the invention improves longitudinal and transverse cooling effects of the steel plate due to being good for more complete contact between fresh cooling water in the back line and the steel plate. The device provided by the invention has advantages of high transverse cooling uniformity, fast longitudinal cooling speed and less water consumption.

Description

technical field [0001] The invention relates to a cooling device for hot-rolled strips in the field of steel rolling. Background technique [0002] The steel production process combining controlled rolling and controlled cooling is called deformation heat treatment process. In the hot-rolled strip production process, the rolled steel plate needs to undergo controlled cooling to control the phase transformation process of the steel material during the cooling process, and obtain the required phase transformation structure and excellent mechanical properties. Controlled cooling is the most important means for rolling mills to improve product quality and develop high value-added products. [0003] The control cooling system consists of three parts: control cooling equipment, water treatment system and control cooling computer system. Controlled cooling equipment is composed of controlled cooling main equipment, water supply pipeline, high-level water tank and circulating wate...
