Description

Technical Field

[0001] This application relates to the field of temperature control technology for coil conveying, and in particular to an automated air control device for coil cooling. Background Technology

[0002] In high-speed wire rod rolling production in the metallurgical industry, the cooling process of high-temperature rolled wire rod is considered the "choke point" that determines the final quality of the product. When the scorching hot wire rod is output from the rolling mill at high speed, its temperature often reaches over 900℃. At this point, the precise control of the cooling rate is directly related to the formation of the internal metallographic structure of the wire rod. Too rapid cooling may lead to the excessive formation of hard and brittle phases such as martensite, which increases the brittleness and reduces the toughness of the wire rod; while too slow cooling will cause the pearlite lamellars to become coarse, which significantly reduces the hardness and tensile strength of the wire rod.

[0003] Air cooling is the mainstream method in wire coil rolling, characterized by low cost and high efficiency. Traditional slow cooling of wire coils has always been manually controlled, which has the disadvantages of low efficiency and large error. Therefore, how to automatically control the air volume during air cooling is a crucial issue. During the wire coil conveying process, the local stacking of the coils causes the heat dissipation efficiency to be inconsistent between the middle and the sides. If the fan blows with the same air volume, it will cause uneven heat dissipation between the middle and the sides, which will affect the cooling effect of the coil along its width and damage the performance of the wire. Summary of the Invention

[0004] This device provides an automated air control system for cooling wire coils, the specific implementation of which is as follows:

[0005] An automated airflow control device for cooling wire coils, comprising:

[0006] Conveyor roller belt for forward conveying of wire coils;

[0007] A fan located below the conveyor belt is connected to the conveyor belt via a longitudinal damper and a fan box, and acts on the coil above the conveyor belt.

[0008] The longitudinal damper includes a first square frame and an adjustment plate hinged inside the first square frame. The tilting direction of the adjustment plate faces the width direction of the conveyor belt. An electric actuator is provided on the outside of the first square frame. The output end of the electric actuator is connected to the main shaft inside the first square frame. The main shaft is connected to the adjustment plate and adjusts its tilting angle.

[0009] The controller has several temperature sensors arranged along its width on the conveyor roller belt. The temperature sensors are electrically connected to the signal input terminal of the controller, and the signal output terminal of the controller is electrically connected to the fan and electric actuator. The air outlet angle of the fan is adjusted by changing the flip angle of the adjustment plate to achieve uniform temperature in the width direction during the transport of the wire coil.

[0010] Based on the above technical solution, when the controller receives the temperature sensor signal, it can continuously rotate in different directions to drive the main shaft to rotate, thereby adjusting the rotation angle of the adjustment plate and controlling the air volume in the middle and sides of the air box, thus improving the cooling effect of the coil edge and avoiding uneven cooling caused by coil stacking.

[0011] Preferably, the conveyor roller belt includes a support frame, and a plurality of rollers are provided on the top of the support frame along the conveying direction of the wire coil. The ends of each roller are connected to the same sprocket drive unit by a sprocket and a chain.

[0012] Preferably, a transverse air distribution nozzle is provided between the top of the air box and the bottom of the conveyor roller belt. The nozzle includes a second square frame, and several air nozzles are equidistantly arranged on the inner side of the second square frame along the conveying direction of the wire roll.

[0013] Preferably, the nozzle includes a variable neck tube and a guide port that are interconnected, with a gap between adjacent rollers, and the air outlet of the guide port is located at the gap position.

[0014] Based on the above technical solutions, the airflow is enhanced by designing a variable neck tube, and the guide port is set at an angle to adapt to the gap between adjacent rollers, that is, to accurately insert into the inside of the rollers, so that the airflow is directly applied to the coil, reducing the waste of airflow, improving efficiency, and achieving better cooling effect; at the same time, it also reduces the excessive pressure in the air box caused by turbulence.

[0015] Preferably, a pointer is hinged to the outside of the first square frame, the pointer is coaxially hinged to the adjustment plate, and an arc-shaped scale plate is also provided on the outside of the first square frame, the pointer pointing to the arc-shaped scale plate.

[0016] Based on the above technical solution, by fixing the pointer and the adjustment plate together, it is ensured that the adjustment plate can swing smoothly left and right, and the tilt state of the adjustment plate can be judged by manually monitoring the swing of the pointer on the scale plate.

[0017] Preferably, it also includes an openable and closable heat insulation cover that acts above the conveyor roller belt; the heat insulation cover includes a cover body and a mounting base located on the side of the conveyor roller belt, which are rotatably connected, and an electric push rod is provided at the rotatable part.

[0018] Based on the above technical solution, the electric push rod is electrically connected to the controller. By extending and retracting the electric push rod, the heat preservation cover is controlled to fasten to the top of the conveyor roller belt, providing heat preservation for the top of the coil during conveying.

[0019] Preferably, the bellows has an upward-opening, bucket-shaped structure, and an inspection port is provided on the side of the bellows. In summary, this application includes the following beneficial technical effects:

[0020] 1. This utility model can greatly reduce labor costs and improve efficiency by setting up a fan, a longitudinal damper and a temperature sensor. The fan speed and air volume are automatically controlled by the temperature sensor. The air volume can also be controlled by changing the size of the damper opening by the temperature sensor, thereby achieving the purpose of accurately controlling the temperature of the rolled wire.

[0021] 2. By setting a single main shaft and electric actuator, this utility model can achieve uniform tilt angle adjustment of each adjustment plate. Furthermore, the external pointer of the adjustment plate works in conjunction with the arc-shaped scale plate, which also facilitates manual inspection after the adjustment plate has automatically adjusted its tilt angle.

[0022] 3. This utility model has a simple structure. According to the rolling requirements, the controller can open or close the heat preservation cover to reduce the loss of surface temperature of the wire coil without affecting the temperature uniformity.

[0023] 4. This utility model achieves synchronous and reverse oscillation of the adjusting plates on both sides by designing trapezoidal threads with different left and right helical directions on the main shaft, thereby realizing the fully open and half-open states. Attached Figure Description
