Embodiment Construction

[0015] In the device for producing flat jets of the present invention, the C-shaped pipe 5, the first strip 3 and the second strip 6 are welded into an outer tube with a slit by welding technology. An inner tube 4 with two rows of neat flow holes and the outer tube are eccentrically fixed by positioning strips 14 to form a cavity between the inner and outer tubes, and the cavity is divided into cavity one a, the minimum distance point c, and cavity two d three parts. The flange 15 at the inlet end of the inner pipe is connected to the cooling medium pipeline, and the outlet end of the inner pipe is welded and sealed with a steel plate 16, and a sewage outlet f is set, and the inner cavity e is discharged by opening the screw plug 12. The inlet end of the cavity between the inner and outer tubes is welded and sealed by the end plate 17, and the outlet end is sealed by the end plate 2 17 and the flange 11, and the cavity between the inner and outer tubes can be discharged by ope...

Abstract

The invention relates to a cooling device generating a flat jet and a manufacturing method thereof, the cooling device is characterized in that an inner pipe and an outer pipe of the cooling device are eccentrically fixed through a positioning strip for forming a cavity between the inner pipe and the outer pipe, a slit is formed in the axial direction, the width of the slit can be regulated through a tightening bolt and a compression bolt, a flange is welded at the inlet end of the inner pipe for connecting with a cooling medium pipeline, a steel plate is welded at the outlet end for sealing,and the cooling device is further provided with an inner cavity pollution discharge port. An end plate is welded at the inlet end of the cavity between the inner pipe and the outer pipe and used for sealing, the outlet end of the cavity and the flange are sealed through the end plate, and pollution can be discharged out of the cavity between the inner pipe and the outer pipe. Two rows of tidy flow through holes are formed on the inner pipe, and a cooling medium enters into the inner pipe via the flange at the inlet end, and then flows into the cavity between the inner pipe and the outer pipe via the flow through holes and further forms flat jet via the slit for cooling the steel plate. The eccentric arrangement of the inner pipe and the outer pipe of the device can form multiple damping effects for the cooling medium, the slit enables the cooling medium to form the uniform flat jet in the width direction of a rolling line, and multiple reinforcing ribs are welded outside the outer pipe in the radial direction for preventing deformation.

Description

[0001] technical field [0002] The invention relates to the technical field of post-rolling cooling in metal processing, in particular to a device for generating flat jets to cool cooling materials, which is used for post-rolling treatment of hot-rolled strip steel and medium-thick plates. Background technique [0003] At present, with the development and research of advanced steel materials, in order to obtain high value-added and recyclable steel products, ultra-rapid cooling after rolling is an important process to improve the performance of steel materials and realize the development of steel types. play an important role. In recent years, a new technology developed internationally for controlling ultra-fast cooling after rolling—ultra fast cooling (UFC, ultra fast cooling) technology has become a new trend in the field of steel rolling technology. [0004] Ultra-fast cooling equipment is a kind of cooling equipment with strong rapid cooling capacity. The maximum cooli...
