Problems solved by technology

Of course, in the prior art this kind of device is made of welded structure, exposed to the strong heat radiation of the rolled steel plate, the thermal stress causes the wide nozzle plane to arch, and the warping deformation will cause the flat jet stream to spread across its entire Variations in thickness across the width resulting in inconsistent cooling of the sheet material resulting in defective products

Embodiment Construction

[0008] The cooling device that can form a flat jet flow is wider than the width of the material to be cooled, and is welded by steel plates, as shown in Figure 1: the cooling device is composed of the rear shell 1, the front shell 2, and the rib plate 6, the upper part The input cooling medium interface 7 is connected at a certain distance, and the interface 7 faces the gap between the flow equalizer 5 (the flow equalizer is the abbreviation of the equalizer structure), as shown in Figure 2, which is characterized in that the rear shell 1 and the front shell The clapboard 3 is vertically welded in the body 2, which divides the integrated shell into upper and lower chambers. The clapboard 3 is welded with a plurality of flow equalizers 5 parallel to the shells on both sides at intervals. The flow equalizer 5 is just a cylinder. The base plate 17 has holes, the base plate 17 and the partition plate 3 are in the same plane, and the upper cooling cavity 4 that can make the cooling ...

Abstract

The cooler capable of forming flat jet is formed through welding steel plates and features that inside the welded casing, there are vertical partition boards, flow homogenizing tubes welded between partition boards, arched plate in the lower part, etc to form the outer coolant circulating cavity, water guiding structure, and adjustable flat jet slot. The cooler is made through spot welding plus intermittent welding, annealing to eliminate stress, and straightening. The present invention has less heat deformation, low manufacture cost, high use effect and long service life.

Description

technical field [0001] The invention relates to a device capable of forming a flat spray stream for cooling plate-shaped materials. Background technique [0002] There is a similar patent application in the prior art, the "device for cooling material by generating a flat jet stream" (CN1263550C) of Lowy Heat Treatment Co., Ltd., which is used to cool plate or strip hot-rolled steel materials, by The two walls of the shell made of cast steel form a 5-meter-wide flat jet nozzle, and the slats are attached to the outer surface of the first wall of the nozzle in the form of a metal seal to adjust the thickness of the flat jet to 1-4mm. When changing nozzles, the gasket strips need to be replaced. This technology is to change the welding manufacturing technology of this equipment in the prior art into castings. The narrow and long structure with a width of 5 meters is not only difficult to cast itself, but also the alignment measures to overcome the deformation of the casting st...
