Problems solved by technology

[0003] 1. The structure design of the spray pipe inside the existing cooling device is single. In the process of jet cooling, the uniformity of the jet flow on the surface of the hot-rolled coil is insufficient, resulting in poor cooling effect; at the same time, most of them are sprayed by connecting an external faucet , without any treatment for the water temperature, the normal temperature water spray makes the cooling efficiency lower;
[0004] 2. During the cooling process, when the surface temperature of the hot-rolled coil is high, a large amount of mist will be generated with the spraying of cooling water, making the visibility inside the cooling device low and the temperature easy to rise, resulting in a cooling effect insufficient

Embodiment 1

[0036] refer to figure 1, a uniform jet cooling device and method for hot-rolled coils, including a support base 1, the support base 1 includes a support frame 11, an adjustment A rod 12, an adjustment B rod 13, a hole 14, a screw 15 and a roller 16 , the center of the surface of the support frame 11 is hollow, which is convenient for the water after spraying to flow into the bottom. The surroundings of the bottom of the support frame 11 are connected with the top of the adjustment A rod 12, and the bottom of the adjustment A rod 12 is sleeved on the adjustment B rod 13 Inside, one side of the surface of the adjustment A rod 12 is provided with a hole 14, and one side of the surface of the adjustment B rod 13 is provided with a screw 15, and the screw 15 is inserted into the inside of the gap 14 for detachable connection, and the bottom of the adjustment B rod 13 Connected with the roller 16; the surface of the support seat 1 is provided with a cooling chamber 2, before use, t...

Embodiment approach

[0040] In order to better demonstrate the implementation method that can realize the cooling of a hot-rolled coil with a uniform jet flow, the steps are as follows:

[0041] S1: The support seat 1 moves the cooling cabin 2 to the processing place of the hot-rolled coil through the roller 16 at the bottom, and the adjustment A rod 12 is inserted in the inside of the adjustment B rod 13, and the position of the notch 14 and the screw 15 is adjusted. After reaching the appropriate height, lock and fix it with the knob screw 15;

[0042] S2: Connect the water inlet pipe 54 at one end of the condensation pipe 5 with the external water source, and connect the pipe body 51 with the external control equipment through the controller 9 to start the switch 53. After the external water source enters the pipe body 51, the inside of the pipe body 51 uses heat The principle of exchange makes the liquid flow through the inner tube and condense to achieve a greater cooling effect, and finally ...

Abstract

The invention discloses a cooling device capable of achieving uniform jet flow for a hot-rolled coil and a method thereof, and belongs to the technical field of jet flow cooling. The cooling device comprises a supporting seat, a cooling cabin is arranged on the surface of the supporting seat, a water storage tank is arranged at the top of the cooling cabin and connected with a condensation pipe, and a spraying assembly and a heat dissipation assembly are arranged in the cooling cabin; a water collecting tank is arranged at the bottom of the supporting seat; a controller is arranged on the outer wall of the cooling cabin. According to the cooling device and method capable of uniformly jetting for the hot-rolled coil plate, a water source enters the pipe body, liquid flows through the inner pipe to be condensed according to the heat exchange principle, and the cooling speed of the hot-rolled coil plate is increased; cooling water flows into the X-axis spraying pipe and the Y-axis spraying pipe from the water storage frame and is sprayed out through the spraying heads, dead-angle-free jet flow is guaranteed, and the cooling function of uniform jet flow is achieved. The motor is started to drive the rotating shaft and the fan blades to rotate, flowing of mist in the cabin body is accelerated, visibility in the cabin body is improved, and the temperature in the cabin body is controlled to a certain degree.

Description

technical field [0001] The invention relates to the field of jet cooling, in particular to a cooling device capable of uniform jet flow for hot-rolled coils and a method thereof. Background technique [0002] Hot rolled (Hot rolled), that is, hot-rolled coils, it uses slabs (mainly continuous casting slabs) as raw materials, and after heating, it is made into strip steel by rough rolling units and finishing rolling units; from the last stand of finishing rolling The hot steel strip coming out of the rolling mill is cooled to the set temperature by laminar flow, and rolled into a steel strip coil by the coiler. The cooled steel strip coil passes through different finishing lines (levelling, straightening, etc.) , cross-cutting or slitting, inspection, weighing, packaging and marking, etc.) and processed into steel plates, flat coils and slitting steel strip products; because the temperature of hot-rolled coils is too high when the processing is just completed, hot-rolled coil...
