[0002] Cold heading steel is generally made of low- and medium-carbon high-quality carbon structural steel and high-quality alloy structural steel. It is used to cold-head and manufacture various mechanical standard parts and fasteners. Because the cold heading process requires the steel to have high cleanliness, the content of Si and Al in the steel is controlled, and controlled rolling and controlled cooling processes are used to avoid the formation of martensite, bainite and Widmanstätten structures, so that the steel has a fine grain and carbide spheroidized structure, thereby improving the plasticity and cold upsetting performance of the steel. The production of cold heading steel requires smelting and processing. In order to ensure the purity of cold heading steel, slag-reducing agents and argon are added during smelting to reduce impurities during smelting.

[0003] In current cold heading steel smelting, slag-forming agents are added manually, which is labor-intensive and dangerous. Argon gas is added and stirring is performed, but the effect of stirring alone is still limited and cannot fully mix the argon gas with the molten steel. Utility Model Content

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] It is understood that the terms “first” and “second” as used herein may be used to describe various elements, but unless otherwise stated, these elements are not limited by these terms. These terms are used only to distinguish one element from another.

[0016] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0017] like Figures 1 to 5 As shown, a cold heading steel processing apparatus according to an embodiment of the present invention includes: The smelting and processing furnace 1 is equipped with a gas supply and mixing component 2 and a feeding component 3 for processing cold heading steel. Gas mixing assembly 2 includes: The mounting bracket 21 is fixedly installed on the smelting and processing furnace 1; Motor 22 is fixedly installed on the end face of fixed frame 21. A power shaft 23 is connected to motor 22, and a stirring rod 24 is fixedly installed on power shaft 23. The lower agitator 25 is fixedly mounted on the power shaft 23, and a centrifugal block 251 is fixedly mounted on the lower agitator 25; The upper agitator 26 is fixedly mounted on the power shaft 23, and the upper agitator 26 is fixedly mounted with the propulsion block 261. The gas supply pipe 27 is fixedly installed on the fixed frame 21. The gas supply pipe 27 is also connected to the smelting furnace 1 and is used to supply argon gas to the smelting furnace 1. Specifically, as a further embodiment of this utility model, the number of stirring rods 24 is two sets, and the two sets of stirring rods 24 are staggered in the height direction of the power shaft 23; Specifically, as a further embodiment of this utility model, the number of centrifugal blocks 251 is several sets, used to centrifuge the gas-liquid mixture, and the number of propulsion blocks 261 is several sets, used to pressurize and flow the liquid. In this embodiment of the present invention, during actual application, when cold heading steel is smelted in a smelting furnace 1, the gas supply pipe 27 supplies argon gas to the smelting furnace 1. At the same time, the motor 22 is energized and drives the power shaft 23 to rotate the stirring rod 24 to stir the gas-liquid mixture. The lower stirrer 25 drives several centrifugal blocks 251 to rotate synchronously. When the centrifugal blocks 251 rotate, the molten steel and argon gas are affected by centrifugal force, causing the molten steel to disperse in all directions, thereby accelerating the flow of the molten steel. The upper stirrer 26 drives several propulsion blocks 261 to rotate rapidly, causing the molten steel to be pressurized and flow rapidly from above the upper stirrer 26 to below the upper stirrer 26, increasing the flow speed of the molten steel. Thus, the molten steel is affected by multiple forces during stirring and presents multiple flow states, making the mixture of molten steel and argon gas more uniform.

[0018] By setting up the gas supply and mixing component 2, the smelting and processing of cold heading steel is optimized. Driven by a motor 22, the molten steel is subjected to a stirring effect without force, thereby further improving the efficiency and uniformity of mixing molten steel with argon gas, and greatly improving the purity of molten steel after cold heading steel smelting.

[0019] like Figures 1 to 5 As shown, in a further embodiment of this utility model, the feeding assembly 3 is used to convey the slag removal agent, and the feeding assembly 3 includes: Storage tank 31 is used to store the slag removal agent; The flow monitoring unit 32 is fixedly installed on the storage tank 31 and is used to monitor the flow rate of the slag removal agent. The feeding box 33 has a feed pipe 331 fixedly installed on it, and the feed pipe 331 is connected to the flow monitoring unit 32. The discharge solenoid valve 34 is fixedly installed on the feeding box 33 and is used to discharge the slag removal agent; The screw conveyor unit 35 is fixedly installed on the pipeline of the discharge solenoid valve 34 and is used to discharge the slag removal agent; The feeding pipe 36 is fixedly installed on the screw conveyor unit 35, and the feeding pipe 36 is also movably connected to the smelting and processing furnace 1; The sealing unit 37 is installed on the feeding box 33 and is used to control the discharge of the slag removal agent; Specifically, as a further embodiment of this utility model, the blocking unit 37 includes: An air pump 371 is fixedly installed on one side of the feeding box 33, and an installation pipe 373 is fixedly connected to the air pump 371. A sealing airbag 372 is installed inside the feed pipe 331, and the sealing airbag 372 is fixedly connected to the installation pipe 373. Electromagnetic exhaust valve 374 is fixedly installed on the other side of the feeding box 33, and electromagnetic exhaust valve 374 is connected to sealing airbag 372. Specifically, as a further embodiment of this utility model, a sealing cover 11 is movably installed on the smelting furnace 1 for sealing the smelting furnace 1; In this embodiment of the present invention, when the slag remover in the storage tank 31 is discharged into the feeding box 33, the flow monitoring unit 32 monitors the flow rate of the slag remover. After the slag remover is delivered to the set monitoring value, the air pump 371 inflates the sealing airbag 372 through the installation pipe 373, causing it to expand and block the feed pipe 331, thus blocking the delivery of the slag remover. The discharge solenoid valve 34 opens, allowing the slag remover in the feeding box 33 to fall into the screw conveyor unit 35 for delivery. The slag remover enters the smelting furnace 1 through the feed pipe 36. The sealing airbag 372 is vented through the electromagnetic exhaust valve 374, allowing the slag remover to continue to be delivered to the feeding box 33. When the slag remover in the storage tank 31 is delivered to the feeding box 33, the repeated inflation and deflation of the sealing airbag 372 can prevent the slag remover from causing blockage.
