Description

Technical Field

[0001] This utility model relates to the field of steel strip heat treatment and cooling technology, specifically to a multi-module quenched steel strip cooling device. Background Technology

[0002] Currently, domestic steel strip heat treatment and cooling devices are typically integrated cooling modules, meaning that a single device can only heat treat a single type of material. For example, spring steel requires rapid cooling, while stainless steel requires gradual cooling, necessitating a buffer cooling process before achieving the final heat treatment effect. In other words, a single heat treatment device cannot simultaneously meet the heat treatment needs of multiple material types.

[0003] In summary, this utility model designs a device that uses a multi-module device in the steel strip cooling module, with each module independently controlling the coolant temperature to meet the cooling needs of different raw materials. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a multi-module quenched steel strip cooling device that can flexibly meet the cooling needs of different materials; it allows for the replacement of cooling templates without stopping the machine, improving production efficiency and yield; it enables continuous low-temperature cooling, increasing hardening thickness and product lifespan; the independent modules have different wear levels, resulting in smaller product hardness errors; the equipment has low energy consumption and is pollution-free.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a multi-module quenched steel strip cooling device, comprising a central controller, a large coolant tank, and a rectangular main body. The central controller is electrically connected to the rectangular main body, and the rectangular main body is connected to the large coolant tank via a water pump. Multiple small coolant tanks are arranged side by side within the rectangular main body, and temperature sensors are installed in the small coolant tanks. Each temperature sensor is connected to the central controller.

[0006] Preferably, a cooling module is provided on the outside of the small coolant tank. The cooling module is connected to a cooling pressure pump. The outlet of the cooling pressure pump is connected to the inlet of the small coolant tank through a pipe. The outlet of the cooling module is connected to the small coolant tank through a pipe.

[0007] Preferably, the cooling module includes a main body, a pressure module, and a cooling contact plate. The pressure module is arranged inside the main body, and the cooling contact plate is arranged between the pressure modules. The cooling contact plate contacts the steel strip for cooling.

[0008] Preferably, the pressure module has a built-in coolant tank with strips.

[0009] Preferably, the central controller is equipped with a power on / off button and a small coolant tank temperature control button.

[0010] The beneficial effects of this utility model are:

[0011] 1. Multiple cooling modules can be flexibly switched and combined to meet the different quenching and cooling needs of various materials.

[0012] 2. Multi-module independent contact templates allow for easy switching under different wear conditions without downtime for replacement, thus improving production efficiency;

[0013] 3. Multiple modules allow for arbitrary temperature control, with independent control of the coolant temperature for each module to meet the cooling requirements of steel strips made of various materials;

[0014] 4. Multiple modules can be used together to replace the contact template without stopping the machine, thus avoiding waste of materials with unstable hardness during downtime and improving the material yield.

[0015] 5. Multiple modules can be used together. Even if one module has poor contact, it will not affect the product quality. The heat treatment hardness is consistent and the error is smaller.

[0016] 6. It can cool high-carbon steel at low temperatures, resulting in stronger hardenability, greater surface hardness and thickness, and a longer material service life.

[0017] 7. The equipment has low energy consumption in production processes, requiring only a few small water pumps to operate;

[0018] 8. During equipment use, the coolant circulates within the cooling tank and does not come into contact with the steel belt, thus causing no pollution to the environment. Attached Figure Description

[0019] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments;

[0020] Figure 1 This is a schematic diagram of the structure of this utility model;

[0021] Figure 2 This is a longitudinal sectional view of the rectangular main body of this utility model. Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Reference Figure 1-2The specific implementation adopts the following technical solution: a multi-module quenched steel strip cooling device, including a central controller 1, a large coolant tank 2 and a rectangular body 3. The central controller 1 is electrically connected to the rectangular body 3, and the rectangular body 3 is connected to the large coolant tank 2 through a water pump 4. Multiple small coolant tanks 5 are arranged side by side in the rectangular body 3. Temperature sensors 6 are installed in the small coolant tanks 5. The temperature sensors monitor the coolant temperature within a certain range. If the temperature is too high, the water pump is started to draw coolant with a lower temperature from the large coolant tank to cool it down. The coolant temperature is controlled to ensure uniform cooling temperature. Each temperature sensor 6 is connected to the central controller 1.

[0024] A cooling module 7 is provided on the outside of the small coolant tank 5. The cooling module 7 is connected to the cooling pressure pump 8. The outlet of the cooling pressure pump 8 is connected to the inlet of the small coolant tank 5 through a pipe. The outlet of the cooling module 7 is connected to the small coolant tank 5 through a pipe.

[0025] 1. The cooling module 7 includes a main body 71, a pressure module 72, and a cooling contact plate 73. The pressure module 72 is disposed on the inner side of the main body 71, and the cooling contact plate 73 is disposed between the pressure modules 72. The cooling contact plate 73 contacts and cools the steel strip. The steel strip is cooled by being pulled between the two cooling contact plates. The cooling contact plates have a rapid cooling effect on the steel strip and also have a shaping effect during the cooling process.

[0026] The pressure module 72 has a built-in coolant tank with strips.

[0027] The central controller 1 is equipped with a power on / off button and a small coolant tank temperature control button.

[0028] The working principle of this specific implementation is as follows: The central controller 1, as the core of the system, dynamically adjusts the operating status of the cooling module 7 by receiving real-time data from the temperature sensors 6 in each small coolant tank 5. When the temperature sensor detects that the coolant temperature of a certain module exceeds the set threshold, the central controller triggers the water pump 4 to draw low-temperature coolant from the large coolant tank 2 and inject it into the corresponding small coolant tank, thereby achieving precise temperature control.

[0029] Each small coolant tank 5 forms an independent circulation loop with its corresponding cooling module 7 via a cooling pressure pump 8. The cooling pressure pump pressurizes the coolant and delivers it to the main body 71 of the cooling module 7. From there, the coolant is distributed to the cooling contact plate 73 via a built-in strip coolant tank in the pressure module 72. After heat exchange with the steel strip, the coolant flows back to the small coolant tank 5. Different small coolant tanks can have different temperature parameters preset by a central controller (e.g., spring steel requires rapid cooling to -65℃, while stainless steel requires stepped buffer cooling). These parameters are coordinated by independent temperature sensors 6 and water pumps 4 to achieve multi-stage differentiated cooling. As the steel strip continuously passes between the parallel cooling modules 7, the cooling contact plate 73 directly contacts the steel strip surface, achieving rapid cooling through conduction heat exchange. The pressure module 72 can adjust the contact pressure according to the steel strip thickness and material characteristics, ensuring cooling efficiency while also providing shaping protection to prevent steel strip deformation during cooling.

[0030] Each cooling module 7 can be started, stopped or switched individually. When a module is worn or malfunctions, the central controller automatically shields the module and adjusts the coolant flow and temperature of the adjacent modules to ensure uniform overall cooling effect (such as the independent control idea of ​​multi-physics coupling in [8]).

[0031] Low-energy circulation: The coolant circulates within a closed tank and is driven only by a small water pump 4 and a cooling pressure pump 8, resulting in significantly lower energy consumption than traditional integrated equipment; moreover, the coolant does not come into direct contact with the external environment, thus avoiding pollution.

[0032] Example 1: Heat treatment of 65Mn steel strip as an example

[0033] The integrated cooling equipment only cools once. Although the cooling module is relatively long, the temperature of the coolant in the latter part of the cooling process is close to 100°C, which does not meet the requirements for rapid and long-term cooling of the steel strip.

[0034] In this embodiment, during the cooling process of 65Mn steel strip, different modules are supplied with coolant independently. Throughout the cooling process, each module is cooled at the lowest temperature. This sustained low-temperature cooling results in a thicker surface, especially for steel strips with a thickness of 1.0mm or more, significantly improving their service life.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
