Description

Technical Field

[0001] This utility model relates to the field of heavy industrial production technology, and in particular to a metallurgical steel rolling equipment. Background Technology

[0002] Steel rolling is a process in the steel industry that refers to the pressure processing of changing the shape of steel billets between rotating rolls. Through steel rolling, steel ingots or billets can be rolled into steel products of various shapes and sizes. The steel rolling process can not only improve the internal structure of steel and enhance its mechanical properties, but also precisely control the size and shape of steel to meet the needs of different fields. Steel rolling production is widely used in manufacturing industries such as construction and machinery.

[0003] The existing steel rolling process, through a fixed roll structure and preset rolling parameters, can achieve preliminary rolling of steel, avoiding large shape deviations and dimensional errors in the steel during the rolling process, ensuring a certain level of product quality, and meeting production needs to a certain extent.

[0004] However, since the positional relationship between the roll spacing and the rolling pressure is relatively fixed, it cannot be quickly adjusted when rolling steel with different thicknesses and size requirements. This means that if it is necessary to switch to rolling different specifications of steel during the production process, it often takes a lot of time to replace the rolls. Moreover, this adjustment method is not very precise and cannot meet the requirements of high-precision steel rolling. At the same time, the fixed rolling structure lacks sufficient flexibility and adaptability when dealing with emergencies or special steel materials, which limits the efficiency and product diversity of steel rolling production.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a metallurgical steel rolling mill, comprising a carrier plate 1. A drive motor 3 is fixedly installed at the top front right end of the carrier plate 1. A gearbox 4 is fixedly installed at the top right side of the carrier plate 1. The output end of the drive motor 3 is fixedly connected to the input end of the gearbox 4. Two trapezoidal supports 5 are fixedly connected to the rear end of the top right side of the carrier plate 1. Two transmission rollers 6 are rotatably connected at the bottom between adjacent trapezoidal supports 5. The front ends of the two transmission rollers 6 pass through the front side of the front trapezoidal support 5 and are fixedly connected to transmission gears 7. The external of the moving gear 7 is meshed with a chain belt 8. The top wall of the two trapezoidal supports 5 is penetrated by an adjusting screw 9. An adjusting roller 10 is set at the top between the two adjacent transmission rollers 6. The bottom ends of the two adjusting screws 9 are rotatably connected to the front and rear sides of the top of the adjusting roller 10, respectively. The outer wall of the two adjusting screws 9 is threaded with a rotary valve 11. The bottom ends of the two rotary valves 11 are rotatably connected to the top wall of the two trapezoidal supports 5, respectively. A cooling mechanism 2 is set on the top left side of the carrier plate 1. The cooling mechanism 2 is used to cool the rolled steel.

[0033] Specifically, when the equipment starts running, the carrier plate 1 serves as the mounting platform. The drive motor 3, mounted on the right front end of its top, starts and transmits power to the gearbox 4. The gearbox 4 adjusts the speed and torque output of the drive motor 3 to meet the requirements of steel rolling. The power processed by the gearbox 4 is then transmitted to the two drive rollers 6. Since the front ends of both drive rollers 6 pass through the front side of the front trapezoidal bracket 5 and are fixedly connected to the drive gears 7, and both drive gears 7 are externally meshed with chain belts 8, the two drive rollers 6 can rotate synchronously. An adjusting roller 10 is set at the top between the adjacent drive rollers 6, and its position can be adjusted by adjusting the screw 9. When it is necessary to change the specifications or thickness of the rolled steel, the operator rotates the rotary valve 11. The valve 11 is threadedly connected to the adjusting screw 9. Rotating the valve 11 causes the adjusting screw 9 to move up and down in the middle of the top wall of the trapezoidal support 5. When the adjusting screw 9 moves up and down, the position of the adjusting roller 10 connected to its bottom end also changes. By precisely adjusting the distance between the adjusting roller 10 and the two drive rollers 6, the rolling requirements of steel of different thicknesses can be met. During the rolling process, the steel passes between the two drive rollers 6 and the adjusting roller 10. The drive rollers 6 provide the main power and rolling pressure, while the adjusting roller 10 plays an auxiliary role in adjusting and controlling the rolling accuracy. The two trapezoidal supports 5 not only provide support for the drive rollers 6 and the adjusting screw 9, but also ensure the stability and safety of the entire rolling process, realizing efficient and precise rolling of steel and meeting the production needs of steel of different specifications.

[0034] Reference Figure 1 and Figure 2 The cooling mechanism 2 includes two L-shaped supports 201. The bottom of the two L-shaped supports 201 is fixedly connected to the middle left side and the rear left side of the top wall of the carrier plate 1, respectively. Multiple conveying rollers 202 are rotatably connected between adjacent L-shaped supports 201 at equal distances. A water tank 203 is fixedly connected to the left front side of the top wall of the carrier plate 1. A booster water pump 204 is fixedly installed on the rear top side of the water tank 203. The input end of the booster water pump 204 passes through the top wall of the water tank 203 and is connected to the inside of the water tank 203. The output end of the booster water pump 204 is connected to a diversion pipe 205. Multiple atomizing nozzles 206 are equidistantly connected to the bottom of the diversion pipe 205. The multiple atomizing nozzles 206 are equidistantly arranged directly above the multiple conveying rollers 202.

[0035] Specifically, after the rolling mill completes the rolling process, the formed steel is conveyed to the cooling mechanism 2. Two L-shaped supports 201, fixedly connected to the middle and rear left sides of the top wall of the carrier plate 1, provide a stable support structure for the entire cooling mechanism 2. Multiple equidistant rotating conveyor rollers 202, rotatably connected between adjacent L-shaped supports 201, begin to operate. The rotation of the conveyor rollers 202 drives the steel forward, ensuring that the steel can pass smoothly through the cooling mechanism 2. During this process, a water tank 203 located at the front left end of the top wall of the carrier plate 1 provides a water source for cooling. A booster pump 204, fixedly installed at the rear top of the water tank 203, draws water from inside the water tank 203 and then delivers it to a distribution pipe 205 through its output. The distribution pipe 205 receives the pressurized water and distributes it evenly to the bottom equidistantly connected... Multiple atomizing nozzles 206 are equidistantly positioned directly above multiple conveying rollers 202. When water is sprayed from the atomizing nozzles 206, it forms a fine water mist. This water mist is directly sprayed onto the surface of the steel moving on the conveying rollers 202. Upon contact with the high-temperature steel, the water mist evaporates rapidly, absorbing a large amount of heat, thus achieving rapid cooling of the steel. During the cooling process, the conveying rollers 202 continuously and stably transport the steel, ensuring that all parts of the steel receive uniform cooling from the water mist. At the same time, the booster water pump 204 continuously operates, ensuring sufficient water pressure and volume, enabling the atomizing nozzles 206 to continuously and stably spray a fine water mist to meet the cooling requirements of the steel. This achieves efficient and uniform cooling of the rolled steel, preventing quality problems caused by high temperatures and improving the performance and quality of the steel.

[0036] Reference Figure 1 , Figure 2 and Figure 5 A controller 12 is fixedly installed on the front side of the top wall of the water tank 203. The controller 12 is electrically connected to the drive motor 3, the gearbox 4, and the booster pump 204. A water filling cover 13 is fixedly installed on the top left end of the water tank 203. The top of the water filling cover 13 is made of a transparent material. A T-shaped frame 14 is fixedly connected to the rear end of the top wall of the carrier plate 1. The top of the T-shaped frame 14 is in contact with the rear end of the diversion pipe 205. Multiple rubber pads 15 are fixedly connected at equal intervals on the left and right sides of the bottom of the carrier plate 1. I-beams 16 are fixedly connected to the bottom of the multiple rubber pads 15 on the left and right ends. Anti-slip pads 17 are fixedly connected to the front and rear ends of the bottom of the two I-beams 16. The bottom of the multiple anti-slip pads 17 is designed to be anti-slip. Two fans 18 are fixedly installed inside the carrier plate 1. The two fans 18 are located directly below the multiple conveying rollers 202.

[0037] Specifically, the controller 12, fixedly installed on the front side of the top wall of the water tank 203, is electrically connected to the drive motor 3, gearbox 4, and booster water pump 204. It can precisely control the speed of the drive motor 3, the gear shifting of the gearbox 4, and the working status of the booster water pump 204 according to actual working needs, thus automating the entire rolling and cooling process. The water inlet cover 13, fixedly installed on the left side of the top of the water tank 203, facilitates the operator in adding cooling water to the water tank 203. The top of the water inlet cover 13 is made of a transparent material, allowing the operator to visually observe the water level in the water tank 203 and add water in a timely manner. The T-shaped bracket 14, fixedly connected to the rear end of the top wall of the carrier plate 1, provides rear-end support and fixation for the diversion pipe 205, ensuring the stability of the diversion pipe 205 during operation. Multiple rubber gaskets 15 are fixedly connected at equal intervals on both the left and right sides of the bottom of the carrier plate 1. The rubber pads 15 act as buffers and shock absorbers. When the equipment vibrates during operation, the rubber pads 15 absorb and reduce the vibration, protecting the various components of the equipment and reducing operating noise. The I-beams 16, which are fixedly connected to the bottom of the multiple rubber pads 15 on the left and right ends, enhance the overall structural strength of the equipment and improve its load-bearing capacity. The anti-slip pads 17, which are fixedly connected to the front and rear ends of the bottom of the I-beams 16, have an anti-slip design, increasing the friction between the equipment and the ground and ensuring that the equipment will not slide or shift during operation. The two fans 18, which are fixedly installed inside the carrier plate 1, are located directly below the multiple conveying rollers 202. During the cooling process of the steel, the fans 18 generate downward airflow, which can accelerate the evaporation of water mist and enhance the cooling effect. At the same time, it also helps to quickly expel the hot air generated during the cooling process, further improving the cooling efficiency.

[0038] Working principle: The carrier plate 1 serves as the mounting platform. The drive motor 3, mounted on the front right end of the top of the carrier plate 1, starts and transmits power to the gearbox 4. The gearbox 4 adjusts the speed and torque output of the drive motor 3 to meet the requirements of steel rolling. The power processed by the gearbox 4 is then transmitted to the two drive rollers 6. Since the front ends of the two drive rollers 6 pass through the front side of the front trapezoidal bracket 5 and are fixedly connected to the drive gears 7, and the external parts of the two drive gears 7 are meshed with chain belts 8, the two drive rollers 6 can rotate synchronously. An adjusting roller 10 is set on the top between the adjacent two drive rollers 6, and its position can be adjusted by adjusting the screw 9. When it is necessary to change the specifications or thickness of the rolled steel, the operator rotates the rotary valve 11. Since the rotary valve 11 is threadedly connected to the adjusting screw 9, the rotation of the rotary valve 11 will cause the adjusting screw 9 to move up and down in the middle of the top wall of the trapezoidal support 5. When the adjusting screw 9 moves up and down, the position of the adjusting roller 10 connected to its bottom end also changes accordingly. By precisely adjusting the distance between the adjusting roller 10 and the two drive rollers 6, the rolling requirements of steel of different thicknesses can be met. During the rolling process, the steel passes between the two drive rollers 6 and the adjusting roller 10. The drive rollers 6 provide the main power and rolling pressure, while the adjusting roller 10 plays an auxiliary role in adjusting and controlling the rolling accuracy.

[0039] Furthermore, the two L-shaped supports 201 fixedly connected to the middle left side and the rear left side of the top wall of the carrier plate 1 in the cooling mechanism 2 provide a stable support structure for the entire cooling mechanism 2. Multiple equidistant rotating conveyor rollers 202 connected between the two adjacent L-shaped supports 201 begin to operate. The rotation of the conveyor rollers 202 drives the steel forward, ensuring that the steel can pass smoothly through the cooling mechanism 2. During this process, the water tank 203 located at the left end of the front side of the top wall of the carrier plate 1 provides a water source for cooling. The booster pump 204, fixedly installed at the rear top of the water tank 203, draws water from inside the water tank 203 and then delivers the water to the distribution pipe 205 through the output end of the booster pump 204. The distribution pipe 205 receives the pressurized water and... The water is evenly distributed to multiple atomizing nozzles 206 that are equidistantly connected at the bottom. Since the multiple atomizing nozzles 206 are equidistantly positioned directly above the multiple conveying rollers 202, when water is sprayed from the atomizing nozzles 206, it forms a fine water mist. This water mist is sprayed directly onto the surface of the steel moving on the conveying rollers 202. After the water mist comes into contact with the high-temperature steel, it evaporates rapidly, absorbing a large amount of heat, thereby achieving rapid cooling of the steel. During the cooling process, the conveying rollers 202 continuously and stably transport the steel, ensuring that all parts of the steel can be evenly cooled by the water mist. At the same time, the booster water pump 204 works continuously to ensure sufficient water pressure and volume, so that the atomizing nozzles 206 can continuously and stably spray out a fine water mist to meet the cooling requirements of the steel.
