Description

Technical Field

[0001] The utility model relates to the field of strip steel processing, in particular to a pre-oxidation device for cold-rolled strip steel. Background Art

[0002] Cold rolled steel strip is a steel strip processed by cold rolling. Cold rolling refers to subjecting steel to a series of pressing and cutting processes at room temperature to reduce the thickness of the steel and change its physical and mechanical properties. After the steel strip is produced, in order to improve its oxidation resistance, the steel strip needs to be pre-oxidized. When the existing device pre-oxidizes the steel strip, it is generally transported by a conveyor belt and a chemical is sprayed on the surface of the steel strip during the transportation process so that the chemical forms a transparent protective film on the surface of the steel strip. However, after one side of the steel strip is treated, the operator needs to turn the steel strip over and then spray the chemical on the other side of the steel strip. This method of operating only on one side of the steel strip at a time is inefficient and cumbersome.

[0003] Therefore, in view of the above problems, a pre-oxidation device for cold-rolled steel strip is now developed, which can simultaneously process the upper and lower surfaces of the steel strip during transportation. Utility Model Content

[0004] In order to overcome the disadvantages of the existing device that the operator needs to turn the steel strip over after processing one side of the steel strip, and then spray the other side of the steel strip with chemicals, and this method of operating only on one side of the steel strip at a time is inefficient and cumbersome to operate, the utility model provides a pre-oxidation device for cold-rolled steel strip which can simultaneously process the upper and lower surfaces of the steel strip during transportation.

[0005] The technical solution of the utility model is: a pre-oxidation device for cold-rolled strip steel, comprising an oxidation chamber, five placement rollers are rotatably connected to the lower part of the oxidation chamber, a plurality of fixed rods are connected to the upper part of the oxidation chamber, a mounting frame is slidably connected between the fixed rods, a driving motor is installed on the top of the oxidation chamber by bolts, a lifting screw is connected to the output shaft of the driving motor, the lifting screw is threadedly connected to the mounting frame, a spraying assembly is connected to the mounting frame, and a lower oxidation mechanism for evenly applying a reagent to the bottom of the strip is provided inside the oxidation chamber.

[0006] As an improvement of the above solution, the lower oxidation mechanism includes a coating component, the coating component is connected to a guide frame, and the guide frame is provided with a guide component.

[0007] As an improvement of the above scheme, it also includes a roller brush mechanism, which includes a mounting frame. There are three mounting frames in total. The mounting frames are connected to the mounting racks by bolts. Two mounting plates are slidably connected to the mounting frames. Springs are connected between the mounting plates and adjacent mounting frames. Application rollers are rotatably connected between the inner sides of the mounting plates.

[0008] As an improvement of the above scheme, the spray assembly includes a dosing pipe, a guide pipe and a spray frame. The dosing pipe is installed on the mounting frame. The left end of the dosing pipe is through-connected with the oxidation chamber. Three guide pipes are connected to the dosing pipe, and the spray frame is connected between the bottoms of the guide pipes.

[0009] As an improvement of the above scheme, the coating assembly includes a connecting frame and a sponge block. The connecting frame is installed between the left and right sides of the oxidation chamber by bolts. The sponge blocks are installed on the connecting frame, and the height of the sponge blocks is higher than the connecting frame.

[0010] As an improvement of the above solution, the mounting plates are provided with limit blocks.

[0011] By adopting the above technical solution, the beneficial effects are:

[0012] 1. The utility model guides and collects the overflowed agent through the guide frame and the guide assembly, so that the sponge in the coating assembly can absorb the agent and apply the agent to the lower surface during the movement of the strip, thereby achieving the effect of simultaneous coating in both directions, and no longer needs to turn over the strip, which greatly improves the efficiency of the strip pre-oxidation treatment.

[0013] 2. When applying the agent to the steel strip, the utility model relies on the movement of the steel strip to drive the application roller to move, so that the application roller applies the agent attached to the upper surface of the steel strip, so that the agent can be evenly attached to the upper surface of the steel strip. During the contact application process, relying on the buffering effect of the spring, the application roller can fit closely on the steel strip to avoid the occurrence of application gaps.

DETAILED DESCRIPTION

[0019] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings. Example 1

[0020] A pre-oxidation device for cold-rolled strip steel, such as Figure 1 and Figure 2 As shown, it includes an oxidation chamber 1, five placement rollers 2 are rotatably connected to the lower part of the oxidation chamber 1, a plurality of fixed rods 3 are connected to the upper part of the oxidation chamber 1, and a mounting frame 4 is slidably connected between the fixed rods 3. A driving motor 5 is installed on the top of the oxidation chamber 1 by bolts, and the output shaft of the driving motor 5 is set to face downward. A lifting screw rod 6 is connected to the output shaft of the driving motor 5, and the lifting screw rod 6 is threadedly connected to the mounting frame 4. A spraying assembly 7 is connected to the mounting frame 4, and the spraying assembly 7 includes a dosing pipe, a guide pipe and a spraying frame. The dosing pipe is installed on the mounting frame 4, and the left end of the dosing pipe is connected to the oxidation chamber 1 in a through-type manner. Three guide pipes are connected to the dosing pipe, and a spraying frame is connected between the bottoms of the guide pipes. A lower oxidation mechanism 8 for evenly applying the agent to the bottom of the strip is provided inside the oxidation chamber 1.

[0021] like Figure 2 and Figure 3 As shown, the lower oxidation mechanism 8 includes a coating component 81, and the coating component 81 includes a connecting frame and a sponge block. The connecting frame is installed between the left and right sides of the oxidation chamber 1 by bolts, and sponge blocks are installed on the connecting frames. The height of the sponge blocks is higher than the connecting frame. The coating component 81 is connected to a guide frame 82 for guiding the feeding of the agent, and the guide frame 82 is provided with a guide component 83 for guiding the agent on the upper surface of the strip.

[0022] It should be noted that when the strip is pre-oxidized, the device can be used to spray the strip with chemicals. First, the strip is placed above the placement roller 2, and the strip is guided by the placement roller 2. During the guiding process, the output shaft of the drive motor 5 is controlled to rotate to drive the lifting screw 6 to rotate, so that the height position of the mounting frame 4 is adjusted, and then the distance between the spray component 7 and the strip is adjusted to achieve the effect of adapting the thickness of the strip. Then, during the conveying of the strip, the upper surface of the strip is sprayed with chemicals by the spray component 7 to form an antioxidant film on the upper surface of the strip. At the same time, the overflowed chemicals will enter the connecting frame in the coating component 81 under the guidance of the guide frame 82 and the guide component 83, and be absorbed by the sponge block in the coating component 81, so that the lower surface of the strip is coated with chemicals during the movement of the strip, achieving the effect of simultaneous coating in both directions of the upper and lower directions. There is no need to turn the strip over, which greatly improves the efficiency of the pre-oxidation treatment of the strip. Example 2

[0023] On the basis of Example 1, Figure 2 and Figure 4 As shown, it also includes a roller brush mechanism 9, which includes a mounting frame 91. There are three mounting frames 91 in total. The mounting frames 91 are connected to the mounting frame 4 by bolts. Two mounting plates 92 are slidably connected to the mounting frame 91. The mounting plates 92 are each provided with a limiting block. Springs 93 are connected between the mounting plates 92 and adjacent mounting frames 91. Application rollers 94 are rotatably connected between the inner sides of the mounting plates 92.

[0024] It should be noted that when the steel strip is coated with the agent, the movement of the steel strip drives the coating roller 94 to move, so that the coating roller 94 coats the agent adhered to the upper surface of the steel strip, so that the agent can be evenly adhered to the upper surface of the steel strip. During the contact coating process, the buffering effect of the spring 93 is relied upon to enable the coating roller 94 to fit tightly to the steel strip to avoid coating gaps.

Therefore, any equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
