Abstract
Description
Technical Field
[0001] This utility model relates to the field of metallurgical equipment technology, specifically to a roller heating device. Background Technology
[0002] In the rolling production of metallic materials, bar stock, as an important intermediate or final product, is crucial for temperature control, which is vital for product quality, production efficiency, and energy consumption. During roller conveying, the bar stock inevitably exchanges heat with the surrounding environment, leading to a temperature drop. This temperature drop during transport causes changes in the internal structure of the material, such as the transformation of austenite into pearlite and ferrite, thus affecting the material's mechanical properties, including strength, toughness, and plasticity. Particularly for high-end steel grades requiring precise control of microstructure and properties, temperature drops can severely impact product quality and even lead to product scrap. To meet the requirements of subsequent processes, such as heat treatment or further rolling, the cooled bar stock often needs to be reheated, affecting the rolling rhythm, increasing mill waiting time, and reducing production efficiency. Therefore, effectively controlling the temperature of bar stock during roller conveying, minimizing temperature drops, and avoiding its adverse effects on product quality and production efficiency has become a pressing technical challenge in the field of metallic material rolling.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0018] like Figures 1 to 4The roller conveyor heating device shown includes a frame base 11, a roller conveyor frame 12 mounted on the frame base 11, a motor frame 13, a roller conveyor assembly mounted on the roller conveyor frame 12, a roller conveyor motor 162 driving the roller conveyor assembly to rotate, and a coupling 161. It also includes a guide plate 14 and a heating device mounted on the guide plate 14. The frame base 11 is fixed to the ground, and the roller conveyor frame 12, made of channel steel, is welded to the frame base 11. The motor frame 13 is also welded to the roller conveyor frame 12. The roller conveyor motor 162 is bolted to the motor frame 13, and the guide plate 14 is fixed to the side of the motor frame 13 via connectors, thus fixing the guide plate 14 above the roller conveyor assembly. The heating device includes a spark generator and a flame-emitting device 173. The spark generator includes a gas supply device 171 and an air inlet 172. The heating device is installed on the guide plate 14 on the side away from the roller conveyor motor 162 and is fixed to the guide plate 14 by the flame-emitting device 173. It also includes necessary piping and control devices. The gas supply device 171 in the spark generator is connected to the piping, allowing the gas to ignite with air entering from the air inlet 172. The flame-emitting device 173 emits a flame to heat the product conveyed on the roller conveyor assembly, ensuring the product maintains a certain temperature during transport, thereby ensuring the uniformity of the product's internal structure and improving its mechanical properties and surface quality.
[0019] Based on the above, such as Figures 1 to 3 As shown, the roller conveyor assembly includes a pair of roller shafts 152 mounted on the roller conveyor frame 12, a roller shaft 153 used in conjunction with the roller shafts 152, and rollers 153 mounted on the roller shafts 153. The rollers 153 are fixed to the roller shafts 153 by welding. Roller shafts 152 are mounted at both ends of the roller shafts 153, and the roller shafts 152 are fixed to the roller conveyor frame 12 by bolts, thereby fixing the rollers 153 in place. The input end of the roller shaft 153 is connected to a coupling 161, which is connected to the output end of a roller conveyor motor 162. The operation of the roller motor 162 drives the rollers 153 to rotate. The operation of the roller motor 162, driving the rollers 153 to rotate, allows the products on the rollers 153 to be transported.
[0020] Based on the above, such as Figure 1 and Figure 2 As shown, the heating device is installed not directly above the roller 153. The flame-spraying device 173 faces the roller conveyor motor 162 to heat the product on the roller 153. The heating device is installed between two connected roller conveyor assemblies, and the flame-spraying device 173 heats the product by spraying flames, ensuring the product's temperature during transport, reducing the need for reheating in subsequent processing steps, and lowering energy consumption and production costs. The heating device can also adjust the heating temperature according to different bar specifications and process requirements, making it widely applicable.
