A split cooling water retaining structure for hot continuous rolling

Abstract

The invention discloses a split type hot continuous rolling cooling water retaining structure which comprises a first mounting frame body, a second mounting frame body and a connecting piece. A roller cooling water collecting pipe is mounted on the concave face of the first mounting frame body, a jet nozzle is mounted opposite to the direction of a working roller in the roller cooling water collecting pipe, a lug piece is arranged on the convex face of the first mounting frame body, and the lug piece is connected with a piston rod of an air cylinder. A water cutting board is mounted at the front end of the second mounting frame body. The front end of the first mounting frame body and the rear end of the second mounting frame body are in L-shaped step face lap joint corresponding to connecting edges, and are fixed through the connecting piece to be integrally connected. According to the split type hot continuous rolling cooling water retaining structure, the front portion of a frame body of the rolling cooling water collecting pipe is designed to be of a split type structure, cooling water on the surface of a roller can be stopped from entering a rolling deformation area, the front portion which can be deformed easily can be replaced quickly and conveniently, the time for maintaining and replacing is shortened, and steel rolling operation efficiency is improved.

Description

technical field [0001] The invention relates to a cooling water retaining device for hot continuous rolling, which is used to prevent the cooling water of rolls of a hot continuous rolling mill from entering the rolling deformation zone, in particular to a split cooling water retaining structure for hot continuous rolling. Background technique [0002] Cooling water is needed to cool the rolls during hot rolling mill rolling, in order to prevent the rolls from being damaged by the heat transfer of high-temperature rolled pieces. At present, known roll cooling devices such as figure 1 , is formed by integral assembly of water cutting plate 9, roll cooling water header 6, roll cooling water header frame body 1' and the cylinder on the frame body. The water cutting plate 9 is made of high-temperature-resistant phenolic resin material, and is installed at the front end of the roll cooling water header body 1'. The surface is in close contact, and the cooling water sprayed from...

Problems solved by technology

[0003] In order to solve the problem that the local deformation of the existing roll cooling water header body cannot be recovered quickly, the present invention provides a split water barrier structure, which can not only prevent the cooling water on the roll surface from entering the rolling deformation zone, but also It is convenient and quick to replace the deformed part, eliminating the influence of local deformation of the roll cooling water header frame
