Description

Technical Field

[0001] This utility model relates to the field of workpiece normalizing and cooling technology, specifically to a high-efficiency adaptive roll normalizing and cooling device. Background Technology

[0002] In the heat treatment process of metallic materials, normalizing is a widely used basic method. Its purpose is to improve the microstructure and properties of metallic materials, such as refining grains, eliminating internal stress, and improving the comprehensive mechanical properties of materials. As a key step in the normalizing process, the normalizing cooling process plays a decisive role in the final properties of metallic materials. Its cooling rate, temperature gradient, and other parameters directly affect the microstructure and mechanical properties of materials. In the production process of rolls, in order to ensure that the product quality meets high industry standards, normalizing cooling treatment is required. At present, the traditional normalizing cooling solution is to place the rolls on a cooling platform for natural cooling. This method is not only inefficient, but also has poor adaptability to changes in the external environment. This can lead to differences in the performance of the same batch of rolls after treatment in different seasons, increasing the difficulty of product quality control. At the same time, natural cooling makes it difficult to dynamically adjust the cooling rate and cannot make targeted adjustments according to the characteristics of rolls of different materials and specifications, resulting in some rolls not achieving optimal performance.

[0003] Currently, various roll normalizing cooling equipment has appeared on the market. For example, Chinese patent application number CN201820817428.9, published on May 30, 2018, discloses a roll normalizing cooling system that uses a dual cooling method of low-temperature gas and atomized water flow, and designs a novel U-shaped air guide frame, significantly improving cooling uniformity. Another example is Chinese patent application number CN202121415579.X, published on February 11, 2022. Patent documents disclose a normalizing device for continuous rolling mill rolls for seamless steel pipes. The device designs a power unit that can drive the rolls to rotate, so that the rolls can dissipate heat evenly during the cooling process and the cooling rate of each part is consistent, resulting in a product with uniform structure and no hardness deviation. The above two patent designs are existing rolling mill roll normalizing cooling equipment, which improve the normalizing effect to a certain extent. However, with the further development of the market and the diversification of rolling mill roll materials, it is necessary to comprehensively consider various normalizing cooling methods such as mist cooling and air cooling, and design a rolling mill roll normalizing cooling equipment for multiple scenarios.

[0010] Preferably, the spray cooling device is located on the outside of the front axle body. The spray cooling device includes a support frame, an inlet pipe, an outlet pipe, a nozzle, and a spray structure. The spray structure consists of a spiral water pipe and a nozzle. The inlet pipe is connected to the front end, and the outlet pipe is connected to the rear end. One end of the inlet pipe is connected to a pumping device. The inlet pipe and the outlet pipe are located in a liquid pool.

[0011] Preferably, the roller gap adjustment device is located below the rear axle body.

[0013] Preferably, the transmission device and the liquid pool are respectively located on both sides of the base.

[0014] Preferably, one end of the water inlet pipe is connected to a pumping device, and the other end is connected to a spiral water pipe.

[0015] Compared with the prior art, this utility model provides a high-efficiency adaptive roll normalizing cooling device, which has the following beneficial effects:

[0016] 1. This high-efficiency adaptive roll normalizing cooling device features a roll rotation device that allows the roll to rotate at a uniform speed during the normalizing cooling process. This ensures that all parts of the roll are in uniform contact with the sprayed coolant, avoiding localized excessively fast or slow cooling. It also prevents internal stress caused by excessive temperature differences, ensures uniform internal structure of the roll, improves the quality and performance stability of the roll, and reduces product defects caused by uneven cooling.

[0017] 2. This high-efficiency adaptive roll normalizing cooling device uses a spray cooling structure composed of spiral water pipes and nozzles. It works with a water pump to draw coolant from the liquid pool for spray cooling. Compared with the traditional natural cooling method, spray cooling can significantly improve cooling efficiency. The nozzles can atomize the coolant into tiny droplets, increasing the contact area between the coolant and the roll and accelerating the heat transfer speed. For rolls of different materials and specifications, the cooling rate can be precisely controlled by adjusting the water pump power and nozzle spray parameters to meet the diverse normalizing cooling process requirements.

[0018] 3. This high-efficiency adaptive roll normalizing cooling device has a roll gap adjustment device that can flexibly adjust the distance between the front and rear rotating shafts. This allows the equipment to adapt to rolls of different sizes, all of which can be stably placed on the roll body rotating device for cooling treatment. Enterprises do not need to purchase multiple sets of cooling equipment for rolls of different specifications, which reduces equipment procurement costs and space occupation, and improves the versatility and use value of the equipment.

[0019] 4. This high-efficiency adaptive roll normalizing cooling device allows the liquid pool to select different coolants according to actual needs. The fan device can accelerate the flow of coolant in the liquid pool, quickly carry the high-temperature coolant away from the vicinity of the pumping device, replenish the low-temperature coolant, and maintain a stable and efficient cooling capacity. The drain hole facilitates the discharge of liquid from the liquid pool during equipment maintenance, coolant replacement, or cleaning of impurities, reducing the difficulty of equipment maintenance, saving maintenance time and costs, and ensuring the normal operation and cooling effect of the equipment.
