Embodiment 1

[0019] Embodiment 1: as figure 1 , 2 A kind of vertical rolling groove special-purpose cooling device shown in and 3, described cooling device is fixedly installed on the outside of vertical rolling groove 1, and described vertical rolling groove 1 is arc-shaped, and described cooling device comprises The cooling water pipe fixing plate 2, the water pipe nozzle nozzle 5, the connecting water pipe 3 and the cooling water tank 4, the cooling water tank 4 is fixedly connected to the cooling water pipe fixing plate 2 through the connecting water pipe 3, and the cooling water pipe fixing plate 2 is Arc type, the radian of the cooling water pipe fixing plate 2 is the same as that of the vertical rolling groove 1, and the distance between the inner side of the arc of the cooling water pipe fixing plate 2 and the outer edge of the vertical rolling groove 1 is 20 to 25 cm. The inner side of the arc edge of the cooling water fixing plate 2 is distributed with a plurality of water pipe ...

Embodiment 2

[0020] Embodiment 2: as figure 1 , 2 As shown in and 3, only one water pipe nozzle nozzle 5 is provided in the same vertical direction inside the arc-shaped side of the cooling water fixing plate 2, and the adjacent two water pipe nozzle nozzles 5 are dislocated and distributed on different heights; the same vertical direction There are only 5 nozzles on the water pipe to ensure that the pressure of the water sprayed by the cooling device at each position is the same, which is convenient for the uniform cooling effect of each position in the horizontal direction of the rolling groove 1. At the same time, the installation height is different, ensuring Uniform cooling effect at each position in the vertical direction of rolling groove 1.

Embodiment 3

[0021] Embodiment 3: as figure 1 , 2 As shown in and 3, the vertical angle between the nozzle nozzle 5 of the water pipe and the cooling water fixing plate 2 is 80-100°. Give the water nozzle 5 a certain angle in the direction of spraying to ensure that after the cooling water is sprayed, there will be no dead space for the cooling of the rolling groove 1, and the cooling water in the upper, middle and lower positions will not interfere with each other; The effect of wasting water.

Abstract

The invention discloses a dedicated cooling device for an edge rolling groove. The cooling device comprises a cooling water pipe fixing board, water pipe water mouth nozzles, a connecting water pipe and a cooling water tank. The cooling water tank is fixedly connected with the cooling water pipe fixing board through the connecting water pipe. The cooling water pipe fixing board is in an arc shape. The distance between the inner side of the arc side of the cooling water pipe fixing board and the outer edge of the edge rolling groove ranges from 20 cm to 25 cm. The multiple water pipe water mouth nozzles are distributed on the inner side of the arc side of the cooling water pipe fixing board. The tops of the water pipe water mouth nozzles are provided with four arc-shaped catches. Water outlets of the water pipe water mouth nozzles are divided into cross-shaped water outlets by the arc-shaped catches. According to the dedicated cooling device for the edge rolling groove, due to the cross-shaped water pipe water mouth nozzles with adjustable angles, the spraying area of cooling water of the nozzles is enlarged, the water pressure is not lowered, after the dedicated cooling device for the edge rolling groove is adopted, cooling on the groove surface is even, and the service life is prolonged by about 20%.

Description

technical field [0001] The invention relates to a cooling device in the steelmaking production process, in particular to a water spray cooling device for a vertical rolling mill roll or a rolling groove in a steel rolling workshop. Background technique [0002] Rolling is the main method of forming metal materials. It is formed by compressing a rolled piece through a rotating roll to change its cross-sectional shape. The rolls in contact with the rolled piece during rolling, due to the high temperature heat transfer of the rolled piece and the internal heat generated by the rolling extrusion, cause the surface temperature of the roll or the groove to rise sharply; thus causing cracks and loss on the surface of the rolling groove The meat wears down, reducing the service life of the roll. Therefore, water cooling of rolls or grooves is very important in the rolling process. [0003] At present, the rolling mills in the steel rolling production workshop are usually arranged ...
