Description

Technical Field

[0001] This invention belongs to the technical field of converter steelmaking equipment, specifically a green and environmentally friendly zero-emission converter steelmaking equipment and its steelmaking process. Background Technology

[0002] Converter steelmaking uses molten iron, scrap steel, and ferroalloys as main raw materials. Without external energy input, it relies on the physical heat of the molten iron itself and the chemical reactions between its components to generate heat, completing the steelmaking process within the converter. Converters are classified by refractory materials (acidic or basic), by the location of gas injection (top-blown, bottom-blown, or side-blown), and by gas type (air converters or oxygen converters). Basic oxygen top-blown and top-and-bottom combined-blown converters are the most widely used steelmaking equipment due to their high production speed, large output, high single-furnace output, low cost, and low investment. Converters are mainly used for the smelting of carbon steel, alloy steel, copper, and nickel.

[0003] Existing green and environmentally friendly zero-emission converter steelmaking equipment requires the addition of slag-forming agents during the steelmaking process. When the slag-forming agents are added, they are not evenly distributed and may clump together. If the slag-forming agents are not evenly distributed, the reaction in some areas may be insufficient, requiring additional energy to supplement the heat required for the reaction, thereby increasing energy consumption. At the same time, the slag and residual steel adhering to the furnace mouth of existing converter steelmaking equipment are quite troublesome to clean after long-term use. Summary of the Invention

[0004] The purpose of this invention is to provide a green, environmentally friendly, zero-emission converter steelmaking equipment and its steelmaking process. Oxygen is introduced into the converter body through an oxygen pipe and a transfer head. A slagging agent is transferred through a transfer hopper and a transfer pipe, falling into a filter frame. Then, a rotary motor is activated, driving a rotary gear. The meshing of the rotary gear and a rotary gear ring causes the rotary gear ring to rotate, which in turn rotates the converter body. A motor further drives a transmission rod, which in turn rotates a fixed gear and one of the fixed bevel gears. The meshing of the fixed gear and the fixed gear ring causes the slagging agent to fall into a filter frame. The filter frame rotates, and through the meshing of two fixed bevel gears, and then through the transmission rod and the meshing of two mounted bevel gears, the oxygen pipe drives the transmission plate to rotate. The rotation direction of the transmission plate is opposite to that of the filter frame, so that the transmission plate evenly transmits the slagging agent into the converter body, reducing slagging agent agglomeration, and at the same time, it can evenly add oxygen. The position of the transmission mechanism is adjusted by the lifting mechanism, and the rotation of the installed motor realizes the rotation of the filter frame and scraper. The lifting mechanism raises and lowers the scraper to clean the furnace mouth of the converter body, automatically scraping off the adhering slag and residual steel.

[0014] A green and environmentally friendly zero-emission converter steelmaking process includes the following steps:

Turn on the lifting motor, the lifting motor rotates and drives the fixed threaded rod to rotate. Through the limit rod limit, the moving block drives the fixed plate and fixed cover to move until the fixed cover seals the converter body.

[0016] Step 2, Steelmaking Process: Oxygen is introduced into the converter body through an external oxygen supply device, oxygen pipe, and transfer head. Slagging agent is transferred through a transfer hopper and transfer pipe, falling into the filter frame. Then, the rotary motor is turned on, driving the rotary gear to rotate. Through the meshing of the rotary gear and the rotary gear ring, the rotary gear ring drives the converter body to rotate.

The rotation direction of the transfer plate is opposite to the rotation direction of the filter frame, so that the transfer plate evenly transfers the slagging agent into the converter body, reducing slagging agent agglomeration. The rotation of the oxygen pipe ensures even oxygen transfer. The molten steel is then transferred out of the converter body through the adjustment mechanism.

[0017] Step 3: Cleaning the converter body furnace mouth: When it is necessary to clean the converter body furnace mouth, adjust the position of the transmission mechanism through the lifting mechanism, and realize the rotation of the filter frame and scraper by the rotation of the motor. The lifting mechanism raises and lowers the scraper to clean the converter body furnace mouth.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0019] (1) In this invention, oxygen is introduced into the converter body through oxygen pipe and transmission head, and slagging agent is transmitted through transmission bucket and transmission pipe. The slagging agent falls into the filter frame. Then, the rotary motor is turned on, and the rotary motor drives the rotary gear to rotate. Through the meshing of the rotary gear and the rotary gear ring, the rotary gear ring drives the converter body to rotate. Then, the motor drives the transmission rod to rotate, and the transmission rod drives the fixed gear and one of the fixed bevel gears to rotate. Through the meshing of the fixed gear and the fixed gear ring, the filter frame rotates. Through the meshing of the two fixed bevel gears, and through the transmission of the transmission rod and the meshing of the two installed bevel gears, the oxygen pipe drives the transmission plate to rotate. The rotation direction of the transmission plate is opposite to the rotation direction of the filter frame, so that the transmission plate transmits the slagging agent evenly into the converter body, reducing the agglomeration of the slagging agent, and at the same time, oxygen can be added evenly.

[0020] (2) In this invention, the position of the transmission mechanism is adjusted by the lifting mechanism, and the filter frame and scraper are rotated by the rotation of the motor. The scraper cleans the furnace mouth of the converter body by the lifting mechanism and automatically scrapes off the adhering slag and residual steel. Attached Figure Description

2. A green and environmentally friendly zero-emission converter steelmaking process, applied in the green and environmentally friendly zero-emission converter steelmaking equipment described in claim 1, characterized in that, Includes the following steps: S1. Input raw materials: Put molten iron into the converter body (1), turn on the regulating motor (204), the regulating motor (204) drives the regulating gear (205) to rotate, and through the meshing of the regulating gear (205) and the regulating gear ring (206), the support ring (203) drives the converter body (1) to a vertical state, turn on the lifting motor (301), the lifting motor (301) rotates and drives the fixed threaded rod (302) to rotate, and through the limit rod (303), the moving block (304) drives the fixed plate (402) and the fixed cover (401) to move until the fixed cover (401) seals the converter body (1); S2, Steelmaking Process: Oxygen is introduced into the converter body (1) through an external oxygen supply device via an oxygen pipe (405) and a transfer head (406). Slagging agent is transferred through a transfer bucket (403) and a transfer pipe (404). The slagging agent falls into a filter frame (408). Then, the rotary motor (501) is turned on. The rotary motor (501) drives the rotary gear (502) to rotate. Through the meshing of the rotary gear (502) and the rotary gear ring (503), the rotary gear ring (503) drives the converter body (1) to rotate. Then, the installed motor (410) drives the transmission rod (416) to rotate. The transmission rod (416) drives the fixed gear (412) and one of the fixed bevel gears. (414) rotates, and through the meshing of the fixed gear (412) and the fixed gear ring (413), the filter frame (408) rotates. Through the meshing of the two fixed bevel gears (414), and through the transmission of the transmission rod (416) and the meshing of the two mounted bevel gears (417), the oxygen pipe (405) drives the transmission plate (407) to rotate. The rotation direction of the transmission plate (407) is opposite to the rotation direction of the filter frame (408), so that the transmission plate (407) evenly transmits the slag-forming agent into the converter body (1), reducing the agglomeration of the slag-forming agent. The oxygen pipe (405) rotates to evenly transmit oxygen, and the molten steel is transmitted out of the converter body (1) through the adjustment mechanism (2). S3. Cleaning the furnace mouth of the converter body (1): When it is necessary to clean the furnace mouth of the converter body (1), adjust the position of the transmission mechanism (4) by the lifting mechanism (3), and realize the rotation of the filter frame (408) and scraper (409) by the rotation of the motor (410). The scraper (409) cleans the furnace mouth of the converter body (1) by the lifting mechanism (3).
