Problems solved by technology

[0017] The purpose of the present invention is to provide a cooling device that produces a flat jet stream. When the cooling device is sprayed for cooling, it does not need to fill the entire box with cooling water every time. When the water spraying is stopped, most of the cooling water It is still stored in the box, and there is always half a box of water in the box, which is always in a cooling state, so as to solve the problems of slow opening water flow, slow closing water flow and poor heat resistance of existing cooling devices

Embodiment 1

[0046] Such as figure 1 As shown, the cooling device of this embodiment includes: a first drain plate and a second drain plate for forming a drainage channel, a box body, a water inlet pipe assembly, a fixed plate and an adjustable plate for forming a slit, and for adjusting The eccentric bolts with the width of the slit and the temperature-resistant sealing strip used to ensure the watertight sealing of the box.

[0047] In this embodiment, a groove is opened on the lower bottom plate of the box body. The groove is a through groove penetrating the lower bottom plate. The first flow guide plate and the second flow guide plate are embedded on the lower bottom plate of the box body through the groove opened. The lower bottom plate is connected with the side wall of the box by bolts, the first baffle and the second baffle are arranged obliquely, and the drainage channel formed by the first baffle and the second baffle is an inclined gap that gradually narrows from top to bottom. ...

Embodiment 2

[0056] Such as image 3 The difference between the second embodiment and the first embodiment is that the cooling device of the second embodiment includes a support plate, the support plate is fixedly installed on the lower bottom plate of the box body, and the adjustable plate passes through The first adjusting bolt is installed on the lower bottom plate of the box body, and the support plate is connected with the adjustable plate through the second adjusting bolt.

[0057] This embodiment shows another form of adjustment of the slit width. In this embodiment, the support plate is fixed on the lower bottom plate of the box body, supported by the support plate, and the relative position between the adjustable plate and the fixed plate can be adjusted by tightening or compressing the second adjusting bolt, thereby adjusting Slit width. This embodiment does not need to use eccentric bolts, and the structure is simple and easy to process.

[0058] The present invention adjusts...

Abstract

The invention relates to a cooling device for generating a flat spraying jet. The cooling device comprises a tank for storing cooling water, and a slot for forming a spraying jet, wherein the slot is communicated with the tank through a drainage channel arranged in the tank. The cooling device further comprises a water inlet pipe component; the upper end of the water inlet pipe component is a cooling water inlet; the cooling water inlet is positioned rightly above the external of the tank; the lower end of the water inlet pipe component is a horizontal round pipe horizontally arranged in the tank; multiple small holes are formed in the two sides of the horizontal round pipe; the upper end of the drainage channel is a spraying jet inlet; the spraying jet inlet is positioned near the top of the tank; the drainage channel is communicated with the slot; the slot is formed by a fixed plate and an adjustable plate; and the width of the slot can be adjusted. The cooling device solves the problems of slow water current opening, slow water current closing and weak heat resistance in a traditional cooling device.

Description

technical field [0001] The invention relates to the technical field of post-rolling cooling in metal processing, in particular to a cooling device for generating flat jet streams, which is used for post-rolling treatment of hot-rolled strip steel and medium-thick plates. Background technique [0002] 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. Due to the high cooling intensity, the slot spray (slit jet) cooling method is more and more used in the field of quenching machines and hot rolling of wide and thick plates that require rapid and strong cooling.
