Description

Technical Field

[0001] This utility model relates to the field of steelmaking equipment technology, specifically to a deoxidizer addition structure for steelmaking converters. Background Technology

[0002] A steelmaking converter is a core steelmaking device that removes impurities from molten iron through an oxygen blowing oxidation reaction. In steelmaking, additives and other auxiliary materials are often added to the steelmaking converter to assist in the smelting of steel. China Patent Network (patent publication number CN218811867U) discloses an additive structure for deoxidizing agents in a steelmaking converter, including a steelmaking furnace. The upper side of the steelmaking furnace has an installation hole, which is an inclined circular through-hole. A fixing pipe is snapped into the installation hole, and a rotary motor is fixedly connected to the upper end of the fixing pipe. A movable shaft is fixedly connected to the output end of the rotary motor corresponding to the inside of the fixing pipe, and a connecting pipe is fixedly connected to the end of the movable shaft away from the rotary motor.

[0003] The aforementioned additive structure enters the fixed pipe through the feed inlet. In conjunction with the rotation of the rotary motor and connecting pipe, the oxidant is forced through the grooves into the connecting pipe, ensuring the material falls evenly into the steelmaking furnace and allows for a uniform reaction between the additive and the molten steel. However, the following problems exist: First, this additive structure is in direct contact with the furnace body, which operates at extremely high temperatures. This can easily cause irreversible high-temperature effects on the additive structure, leading to structural deformation or damage to the motor. Second, during addition, the feed inlet remains relatively close to the furnace body, compromising the safety of personnel. Utility Model Content

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] This embodiment provides, for example Figure 1-4 The deoxidizer addition structure for a steelmaking converter shown includes a main rod 1, which includes a conveying rod 101 and a gripping mechanism 2 sleeved on the conveying rod 101. Slide grooves 102 are provided on the outer walls of both sides of the conveying rod 101, and a mixing cylinder 103 is fixed to one end of the conveying rod 101. A main handle frame 104 is fixed to the center of the top of the mixing cylinder 103, and addition pipes 105 are distributed on both sides of the main handle frame 104.

[0023] To ensure the safety and versatility of deoxidizer addition structures when adding deoxidizers to steelmaking converters, such as... Figure 1-3 As shown, this deoxidizer addition structure consists of a conveying rod 101, a mixing cylinder 103 at both ends, and a discharge pipe 113. The user can hold the main handle frame 104 with one hand and the adjustable grip mechanism 2 with the other, aligning the discharge pipe 113 at the far end of the conveying rod 101 with the steelmaking converter mouth. This, in conjunction with the auger structure composed of the internal conveying shaft 109 and the conveying screw frame 110, stably conveys the additive material into the furnace. The addition process over a longer distance provides operational safety, and the structure does not need to directly contact the furnace body, thus avoiding any impact. While the aforementioned mixing chamber 108 is conveyed by the conveying shaft 109 driven by the motor 107, it can also be used with the addition pipes 105 symmetrically distributed on both sides of the top to add different kinds of additives. At the same time, it is used with the mixing screw frame 111 to carry out the mixing process. Different additives can be added and mixed according to production needs, providing convenience.

[0024] like Figure 4-5 As shown, the gripping mechanism 2 includes a secondary grip frame 201. Buckles 202 are fixed on both sides of the bottom end of the secondary grip frame 201. The buckles 202 are sleeved on the outer wall of the conveying rod 101, and guide rails 203 are fixed on the inner walls of both sides of the buckles 202. A pressing block 204 is telescopically connected to the top of the secondary grip frame 201. An inner linkage frame 205 is fixed on the bottom surface of the pressing block 204.

Pressure blocks 207 are fixed on both sides of the bottom end of the inner linkage frame 205, and rubber pads 208 are fixed on the bottom surface of the pressure blocks 207.

[0025] Furthermore, the inner linkage frame 205 forms an elastic telescopic structure with the inner part of the auxiliary grip frame 201 through the spring 206, and the pressure block 207 and the rubber pad 208 are symmetrically distributed along the two sides of the bottom end of the inner linkage frame 205; the top of the inner wall of the buckle 202 is telescopically engaged with the pressing block 204, and the inner wall of the buckle 202 is in contact with the outer wall of the conveying rod 101.

[0026] To facilitate user gripping of the secondary grip bracket 201 during addition, such as Figure 4-5 As shown, the gripping mechanism 2 of this deoxidizer adding structure mainly consists of a secondary grip frame 201 and two sets of buckles 202. The gripping position of the secondary grip frame 201 can be changed according to the lifting height of the end of the discharge pipe 113 of the overall conveying rod 101 during addition. After the buckles 202 slide along the conveying rod 101, they grip the pressing block 204, which makes the pressing blocks 207 at both ends of the inner linkage frame 205 press against the top surface of the conveying rod 101. This maintains the adjustment and positioning of this position, making it convenient to hold stably in this adjusted position and easy to bear force.

[0027] In summary, when using the deoxidizer addition structure provided in this embodiment, the user first places the required additives, such as deoxidizers, into the mixing chamber 108 inside the mixing cylinder 103 through the addition tube 105. Then, the user holds the main handle 104 with one hand and the auxiliary handle 201 with the other, aligning the discharge pipe 113 at the end of the conveying rod 101 with the steelmaking converter opening. Depending on the position of the force point, the user adjusts the position of the connecting buckle 202 on the auxiliary handle 201 by sliding it along the slide 102, and then tightens the grip to apply pressure to the pressing block 204. The fixed inner linkage frame 205 extends the pressure blocks 207 at both ends downward synchronously under pressure, and the rubber pads 208 on the bottom surface of the pressure blocks 207 maintain friction against the top surface of the conveying rod 101. After the adjustment is completed, the motor 107 is started, and the motor 107 drives the conveying shaft 109, the conveying screw frame 110 and the mixing screw frame 111 to rotate synchronously. At this time, the additive particles in the mixing chamber 108 are conveyed and mixed synchronously as the mixing screw frame 111 rotates, and then sent to the conveying screw frame 110 for further conveying until they are discharged from the discharge pipe 113, completing the non-contact addition process.
