Description

Technical Field

[0001] The invention relates to the technical field of heat setting machines, in particular to a heat treatment device for roller production. Background Art

[0002] Rollers are the main working parts and tools on the rolling mill that cause continuous plastic deformation of metal. Rollers are mainly composed of three parts: roll body, roll neck and shaft head. The roll body is the middle part of the roll that actually participates in rolling metal. During production, the roll needs to be heat treated to greatly improve the hardness and material strength of the roll, so as to better meet the use requirements.

[0003] A Chinese patent with announcement number CN114622083B discloses a heat treatment device for repairing rolling mill rolls. When heat treating the rolling mill rolls, the device uses a material placement table placed on a trolley body to place the rolling mill rolls, and then the trolley body moves on a track and enters a heating hood to heat treat the rolling mill rolls. When heating the rolling mill rolls, the trolley body will absorb a portion of the heat, resulting in a large energy loss. Moreover, the use of the trolley body to feed and unfeed materials cannot ensure the preservation of heat, and a large portion of the heat will be dissipated and lost to the outside, thereby increasing the energy loss. At the same time, the trolley body is large in size, and when the rolling mill rolls are sent out, the roll hoisting personnel cannot get close to the trolley body, and they need to cool down before they can get close, which has a certain impact on the production of rolling mill rolls.

[0004] The above-mentioned heat treatment device for roller repair cannot ensure the preservation of heat well when performing heat treatment on the roller. At the same time, the loading and unloading of the roller requires the control car body to move back and forth, which makes the loading and unloading of the roller inconvenient and also affects the production efficiency of the roller.

The roller body was pushed into the inner side of the cover by a moving trolley, and the guide assembly was used to guide the roller body during feeding. During the experiment, the lifting speed of the guide assembly was 5mm / s, the feeding speed of the moving trolley was 20mm / s, and the moving speed of the pushing mechanism was 15mm / s. After multiple operation tests, it was found that the average feeding and discharging time of the roller body was 2 minutes, which saved 50% of the time compared with the traditional crane operation, and the operation was stable without jamming, ensuring the high efficiency of the heat treatment.

[0044] The experimental data comparison table is as follows:

[0045] It can be seen from the data that the feeding and discharging methods of the present invention are significantly more efficient than the traditional methods, saving about 4.5 minutes of operation time. Example 3

[0046] In order to evaluate the advantages of the present invention in heat preservation, the same model of roller body GD400 was selected and heat treated with an electric heating tube. The power of the electric heating tube was 15kW and the temperature was set to 850°C. The roller body was pushed into the cover, the door panels and the discharge baffles of the feed and discharge ports were closed, and the temperature inside the cover was monitored using a thermocouple. Compared with the traditional trolley feeding method, the results showed that the temperature drop rate in the cover using the device of the present invention was 0.5°C / min, while the temperature drop rate of the traditional trolley feeding method was 1.8°C / min. The present invention significantly reduces heat loss and has a better heat preservation effect.

[0047] The experimental data comparison table is as follows:

[0048] Experimental results show that the heat preservation effect of the present invention is better, and it can effectively reduce heat energy loss and improve energy utilization. Example 4

[0049] In order to verify the uniformity of the heat treatment of the roller body, this example uses a roller body of model GD400, the heat treatment temperature is set to 850°C, and the heating time is 4 hours. During the heat treatment process, the drive mechanism drives the roller on the support roller to rotate at a speed of 5rpm to ensure uniform heating of the roller body. By arranging 10 thermocouples at different positions on the surface of the roller body and recording the temperature changes, it is measured that the temperature difference at each position is kept within ±10°C, while the temperature difference of the traditional non-rotating method is as high as .

[0050] The experimental data comparison table is as follows:

[0051] Through data analysis, the present invention can significantly improve the heat treatment uniformity of the roller body, thereby improving product quality. Example 5

[0052] The present invention is provided with a discharge baffle rotatably connected to the cover shell, which can automatically block the discharge port under its own weight without manual intervention. In order to evaluate the operational convenience and reliability of the structure, 100 continuous discharge operation experiments were conducted. The experimental results show that the discharge baffles can automatically open when the roller is pushed up, and automatically close after the roller is moved out, without any jamming or operational failure, ensuring the simplicity and flexibility of operation.

In the experiment, the same roller body was heated using the conventional trolley method and the heat treatment device of the present invention, the temperature was set to 850°C, the heating time was 4 hours, and the energy consumption was recorded using an electric energy meter. The results showed that the energy consumption of the present invention was 60kWh, while the energy consumption of the conventional trolley method was 85kWh.

[0056] The experimental data comparison table is as follows:

[0057] Through comparative analysis, the present invention significantly reduces energy consumption, saves about 30% of electric energy, and has a good energy-saving effect.

[0058] Working principle: When the roller body 9 is heat treated, the roller body 9 is moved to the feed port 33 by a trolley, and the roller body 9 is pushed into the inner side of the cover shell 3. At this time, the raised guide roller 81 guides the roller body 9. When the roller body 9 enters the appropriate position, the guide roller 81 drops. At this time, the support roller 21 supports the roller body 9, and then the door plate 34 is closed. At this time, the electric heating tube 6 starts to heat the roller body 9. At the same time, the driving mechanism 22 drives the support roller 21 on one side to rotate and drive the roller body 9 to rotate. After the heat treatment is completed, the guide roller 81 is lifted again to lift the roller body 9. At this time, the roller body 9 is pushed to the left by the pushing mechanism 7 and pushed out through the discharge port 32, thereby completing the heat treatment of the roller body 9; When the driving mechanism 22 drives the support roller 21 to rotate, the driving motor 224 is used to drive the driving gear 223 to rotate. The rotating driving gear 223 drives the rotating gear 222 to rotate. The rotating gear 222 drives the transmission rod 212 to rotate through the connecting shaft 221. The transmission rod 212 drives the roller 211 to rotate, thereby completing the rolling support. When the pushing mechanism 7 pushes the material, the moving motor drives the moving screw 72 to rotate, and the rotating moving screw 72 drives the sliding block 732 to move to the left, and the moving sliding block 732 drives the push rod 734 to move to the left, thereby pushing the roller body 9 to the left for discharging.
