Embodiment 1

[0038] Step 101, clip the material roll into the bracket, the bracket is located in the kiln body with a movable door, and the bottom of the kiln body has an air inlet connected to the air duct.

[0039] The air in the kiln body enters the air duct through the air inlet to generate flow, and the heat emitted by the material roll is drawn out of the kiln body. The air inlet is generally set at the front end of the kiln body, and the material roll enters the kiln body from the rear end of the kiln body.

[0040] The crown can be used to clamp the roll into the bracket, and the shape of the bracket can be adaptively adjusted according to the shape of the support of the roll.

[0041] Step 102, closing the movable door of the kiln body.

[0042] The dodge door can be operated by a link mechanism, a hydraulic device or any existing equipment or parts that can make the dodge door open and close.

[0043] Step 103, turn on the fan at the other end of the air duct.

[0044] Turn on...

Embodiment 2

[0046] Step 201, clip the material roll into the bracket, the bracket is located in the kiln body with a movable door, and the bottom of the kiln body has an air inlet connected to the air duct.

[0047] Step 202, closing the movable door of the kiln body.

[0048] Step 203, turn on the fan at the other end of the air duct.

[0049] Step 204, turn on the forward movement switch of the transmission chain, and the bracket is located on the transmission chain.

[0050] After the chain movement switch is turned on, the material roll on the bracket moves along with the chain, thereby changing its position, further accelerating the flow of surrounding air and accelerating cooling.

[0051] The chain can be driven by a bipolar direct-connected reducer.

Embodiment 3

[0053] Step 301, clip the material roll into the bracket, the bracket is located in the kiln body with a movable door, and the bottom of the kiln body has an air inlet connected to the air duct.

[0054] Step 302, closing the movable door of the kiln body.

[0055] Step 303, turn on the fan at the other end of the air duct.

[0056] Step 304, turn on the forward movement switch of the transmission chain, and the bracket is located on the transmission chain.

[0057] Step 305 , when the material roll reaches one end of the kiln body, turn off the forward movement switch of the transmission chain.

[0058] Step 306, turn on the reverse movement switch of the transmission chain.

[0059] Step 307, when the material roll reaches the other end of the kiln body, turn off the reverse movement switch of the transmission chain.

[0060] Step 308, turn on the forward movement switch of the transmission chain again.

[0061] Steps 305-308 can be repeated many times, so that the mater...

Abstract

The invention discloses a method for cooling a material roll, and the method comprises the following steps: clamping the material roll in a bracket, wherein the bracket is positioned in a kiln body with a movable door, and an air inlet is arranged at the bottom of the kiln and connected with an air duct; closing the movable door of the kiln body; and opening a fan at the other end of the air duct. By utilizing the method, the current method of cooling the annealed material roll can be changed, the time for cooling the material roll is shortened by a mild and natural means, and the surface quality of the material roll is not damaged.

Description

technical field [0001] The invention relates to the technical field of coil cooling, in particular to a method for cooling coils. Background technique [0002] At present, in the metallurgical industry, the cooling of the sheet, strip and foil coils after the annealing process is mostly placed in a ventilated environment for natural cooling, or fan-type blowing devices are used for cooling. These cooling methods are time-consuming and ineffective, requiring a large amount of space for stacking the annealed coils. Another type of cooling method is to use rapid cooling, such as using cooling equipment with water flow around it, or energized cooling equipment. Although this type of cooling method takes a short time, rapid cooling will cause cracks in the plate and strip, resulting in waste products and high energy consumption. high. [0003] Therefore, it is necessary for the industry to find a cooling method that can accelerate the cooling of the annealed material without ca...
