Embodiment Construction

[0021] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, but not for limiting the protection scope of the present invention.

[0022] As shown in the figure, the cooling water pipe of this embodiment includes a water pipe body 2 with an arc shape adapted to the outer circle of the roll 1 and a plurality of water nozzles 3 evenly distributed on the water pipe body 2. The cross section of the water pipe body 2 It is a rectangle, and the faucet of this embodiment is arranged on the long side of the rectangle, so that the water outlet along the width direction of the water pipe is consistent and does not diverge, so as to avoid the situation that the arc-shaped water divergence is not concentrated in the pipe body structure in the prior art. In this example, the normal line at the intersection of ...

Abstract

The invention discloses a cooling water pipe, and belongs to the technical field of rolling mill and roller cooling. The cooling water pipe comprises a water pipe body having an arc shape adaptive to an outer circle of a roller, and multiple water nozzles uniformly distributed on the water pipe body, wherein the section of the water pipe body is rectangular; and the center line of any water nozzle in the multiple water nozzles is not perpendicular to a normal in the surface intersection of the roller. The rectangular water pipe body is provided, so that the water outlet quantity can be increased without water pressure difference, and the cooling effect is improved; as the center lines of the water inlet nozzles are not perpendicular to the normal on the surface of the roller, cooling water can be prevented from splashing to reduce the use efficiency; and meanwhile, under a certain conditions, a proper angle can be arranged for wrapping the cooling water on the surface of the roller to strengthen the cooling effect.

Description

technical field [0001] The invention belongs to the technical field of rolling mill roll cooling, and in particular relates to a water pipe used for rolling mill roll cooling. Background technique [0002] The existing bar roll cooling water pipe is simple to manufacture, and an ordinary water pipe is used to bend an arc corresponding to the roll, and then process multiple water spray ports on the inner arc surface. Although the structure is relatively simple, the water pipe has many defects: 1. The sprayed water is divergent, and there is not much water that is actually aimed at the rolling groove for cooling; 2. The sprayed water is at a perpendicular angle to the surface of the roll, and the The water splashed on the roller surface immediately, and the water sprayed from each water nozzle can only cool a small section of the roller, resulting in poor cooling effect; The high temperature area is far away, and the water coming out cannot form a jet, so the cooling effect o...
