Description

Technical Field

[0002] High-speed steel hot rolling mill is an industrial equipment that heats high-speed steel to above its recrystallization temperature and plastically deforms it through rotating rolls at this temperature. It is mainly used to produce steel products of various shapes and sizes, such as plates, strips, bars, wires, and profiles. During the hot rolling process, the plasticity of high-speed steel is improved, making rolling easier. At the same time, hot rolling can also improve the microstructure and mechanical properties of the metal, and increase the density and uniformity of the material.

This process is called water-gas reaction, which will aggravate the formation of oxide scale. Therefore, to address the above problems, a hot rolling device for high-speed steel production with a scrap collection function is proposed. Utility Model Content

[0027] Please see Figure 1-6 This utility model provides a technical solution:

[0028] A high-speed steel production hot rolling device with waste collection function includes a base 1 and a bearing 2. The bearing 2 is fixedly connected to the top of the base 1, and a collection box 3 is fixedly connected to the inner side of the base 1.

This design can effectively filter the moisture in the waste material and ensure the cleanliness of the waste material. At the same time, after the drive motor 4 is started, it will not affect the normal rotation of the air guide duct 54.

[0030] As a further implementation of this solution, a through hole is provided on the inner side of the connecting plate 51, and the inner side of the connecting plate 51 is fixedly connected to the inner side of the lower end of the air guide duct 54.

The top end of the first conical block 53 is in contact with the bottom end of the hot rolling device body 61. A through hole is provided on the inner side of the first conical block 53 near the air guide duct 54. The shape of the first conical block 53 is a slotted cone, which facilitates the first conical block 53 to move away from the hot rolling device body 61 after the electric telescopic rod 52 is activated, so that the waste inside the hot rolling device body 61 can be discharged. The shape of the first conical block 53 helps the waste to fall off automatically.

[0031] As a further implementation of this solution, the air guide duct 54 is a slotted cylinder. The air channel 59 passes through the lower end of the air guide duct 54. A gap is provided between the slot plate 56 and the air guide duct 54. The air outlet 57 passes through the inner side of the air guide duct 54. The number of first conical blocks 53 is the same as the number of filter blocks 58. An installation groove is provided on the inner side of the air guide duct 54 near the hydraulic rod 72. The lower end of the hydraulic rod 72 is fixedly connected to the lower end of the installation groove of the air guide duct 54. The outer side of the upper end of the air guide duct 54 is fixedly connected to one side of the upper fixed square plate 62. After the drive motor 4 is started, the air guide duct 54 can drive the hot rolling device body 61 to rotate, thereby forming the airflow. At the same time, it can move the waste inside the hot rolling device body 61, improving the cooling efficiency of the waste.

[0032] As a further implementation of this scheme, the storage tank 64 penetrates the inner side of the hot rolling device body 61, and the cold air inlet 63 is located near the upper fixed square plate 62. The cold air inlet 63 penetrates the inner side of the hot rolling device body 61, and the hot rolling device body 61 is connected to the storage tank 64. The upper and lower ends of the storage tank 64 in the hot rolling device body 61 are both conical in shape. The lower end of the second conical block 71 fits against the upper end of the storage tank 64 in the hot rolling device body 61, and the second conical block 71 is slotted. The cylinder has a through hole on the inner side of the second conical block 71 near the spray head 73. The inlet of the water pump 75 is connected to the inner side of the water tank 76, and the outlet of the water pump 75 is connected to the inner side of the water pipe 74. The water pipe 74 is connected to the inner side of the spray head 73 through the second conical block 71, which facilitates the second conical block 71 to move upward after the hydraulic rod 72 is activated. This allows high-speed steel to be placed and removed from the upper end of the hot rolling device body 61. At the same time, the water pump 75 delivers water to the waste material to clean it.

[0033] Workflow: During the collection of hot-rolled scrap after low-temperature hot rolling, to prevent impurities from forming in the scrap, the hydraulic rod 72 is activated to move the second cone block 71 and the device at the upper end of the second cone block 71 upwards. When the second cone block 71 moves away from the hot rolling device body 61, high-speed steel is placed into the hot rolling device body 61 from the upper end of the hot rolling device body 61. The high-speed steel is then hot-rolled by the hot rolling device body 61. After hot rolling is completed, the hydraulic rod 72 is activated again to remove the high-speed steel from the upper end of the hot rolling device body 61. The remaining scrap is then collected. First, the scrap is cooled by air cooling. The drive motor 4 is then activated to pass through the seam... The gap plate 56 drives the air guide tube 54 to rotate, and the air guide tube 54 drives the hot rolling device body 61 to rotate via the upper fixed square plate 62. The hot rolling device body 61 is rotatably connected to the base 1 via the bearing 2. The bearing 2 can reduce the friction when the hot rolling device body 61 rotates. When the air guide tube 54 rotates, it drives the fan blades 55 fixed on the inner side to rotate. After the fan blades 55 rotate, they guide the airflow. At this time, a negative pressure is formed inside the hot rolling device body 61. Under the action of the negative pressure, the external air enters the storage tank 64 from the cold air inlet 63. After entering the air outlet 57, it passes through the filter block 58 to filter impurities in the air. The cold air inlet 63 is located near the... The air vent 57 is located near the lower part of the hot rolling mill body 61, near the upper part of the hot rolling mill body 61, to facilitate airflow from top to bottom, thereby achieving the effect of cooling the scrap inside the hot rolling mill body 61. When the hot rolling mill body 61 rotates, it drives the inclined plate 65 to rotate. The inclined plate 65 has an inclined structure, which can push the scrap inside the hot rolling mill body 61 upward, improving the cooling speed of the scrap. After cooling is completed, the water pump 75 is started. The water pump 75 delivers water from the water tank 76 through the water pipe 74 and the second cone block 71 to the inside of the water spray head 73, and sprays it out from the inside of the water spray head 73 in a high-pressure form, thereby cooling the hot rolling mill body 61. The impurities on the surface of the waste inside the main body 61 are cleaned. After cleaning, the electric telescopic rod 52 is activated to move the first cone block 53 downward. When the first cone block 53 moves away from the hot rolling device main body 61, the waste inside the hot rolling device main body 61 slides from the outside of the first cone block 53 into the collection box 3. The water in the waste is filtered through the through hole at the bottom of the collection box 3, thereby achieving the effect of waste collection. The device perfectly avoids the formation of oxide scale during waste recycling by using air cooling before cleaning, thus improving the quality of the waste after collection. At the same time, the device has the function of quickly cleaning and collecting waste, improving the convenience of use.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
