った。A conventional descaling device is disclosed in Japanese Patent Application Laid-Open No. 57-32820.
As described in the publication, the nozzle is raised and lowered according to the thickness of the plate, but the nozzle raising and lowering mechanism is not described. Regarding the effect of descaling, the ideal distance between the material surface and the nozzle is generally 300 to 350 mm. However, in a descaling device installed in a rolling mill that is used for both steel ingots and steel slabs, when rolling steel ingots that do not require descaling, the distance between the upper nozzle and the optical surface of the steel ingot is 300~ At a distance of 350mm,
The life of the upper nozzle is shortened due to the thermal effect of the steel ingot. No consideration was given to raising and lowering the nozzle of the descaling device attached to the rolling mill used for both steel ingots and slabs.

することにある。During rolling, the hydraulic cylinder is operated to raise this device to a position where the thermal effect on the steel ingot is reduced.When rolling a billet that requires descaling, the hydraulic cylinder is operated and this device is raised to a position where the thermal effect on the steel ingot is reduced. It is an object of the present invention to provide a hydraulic lifting type descaling device f that is lowered to the most suitable position for descaling.
〔発明の概要〕 。[Summary of the invention].
本発明の要点は、デスケーリング装置が単独に昇降可能
となるよう、デスケーリング装置と油圧シリンダーを連
結させたことにある。The gist of the present invention is that the descaling device and the hydraulic cylinder are connected so that the descaling device can be raised and lowered independently.
以下、本発明の一実施例を第１図から第３図により説明
する。An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

合わせているため、フード１は自由に上昇可能である。When the billet material 7 requiring descaling is conveyed on the table rollers 9, the hood 1 is connected to the hydraulic cylinder 4 via the bin 10, so the hood 1 is lowered. Note that the hydraulic cylinder 4 is fixed to the frame 11 via a cylinder pin 12. or,
The hood 1 is moved up and down by a sliding liner 3 attached to the housing 2, which positions the hood 1 so that it does not sway during the up and down movement. The pipe 13 is combined with the rotary joint 6,
When the copper ingot material 8, which can move freely as the hood goes up and down and does not require descaling, is conveyed on the tape roller 9, the cylinder rod 14 of the hydraulic cylinder 4 is pulled up and the hood 1' Therefore, it is possible to reduce the adverse effects such as deformation of the descaling device due to the thermal influence of the material 8 of the steel ingot.Even when the hood 1 is raised, the piping 13 is located at the rotary joint 6. The hood 1 can be raised freely.

るためである。When the hydraulic cylinder 4 is stroked to lower the hood 1, the lower surface of the hood 1 is positioned by the stopper 15. This is to prevent the hydraulic cylinder 4 from being adversely affected by high pressure water for descaling work.

多目的圧延機として、使用可能である。According to this embodiment, when rolling the steel ingot material 8, the hood 1 can be raised depending on the stroke amount of the hydraulic cylinder 4 so as to reduce the thermal influence. Furthermore, when rolling the steel billet material, the distance between the top surface of the steel billet 7 and the nozzle 19 provided in the descaling device can be adjusted to an optimal position. Therefore, it can be used as a multi-purpose rolling mill that can be used for both rolling steel ingots and steel slabs.
