Description

Technical Field

[0001] The utility model relates to the technical field of steelmaking auxiliary material adding devices, in particular to an auxiliary material adding device for automated steelmaking of a steelmaking converter. Background Art

[0002] Steelmaking refers to controlling the carbon content (generally less than 2%), eliminating harmful elements such as P, S, O, and N, retaining or increasing beneficial elements such as Si, Mn, Ni, and Cr, and adjusting the ratio between elements to obtain the best performance. Put the pig iron for steelmaking into the steelmaking furnace and melt it according to a certain process to obtain steel. Steel products include ingots, continuous casting billets, and various steel castings directly cast. The steel usually refers to steel rolled into various steel materials. Steel belongs to ferrous metals, but steel is not completely equal to ferrous metals. In the steelmaking process, it is often necessary to add raw and auxiliary materials to the molten steel. Many raw and auxiliary materials (such as silicon carbide particles) are in powder and granular form. At present, the commonly used method of adding is to manually sprinkle the raw and auxiliary materials from the furnace door to complete the addition of raw and auxiliary materials to the molten steel.

DETAILED DESCRIPTION

[0021] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1 to Figure 3 As shown, a device for adding auxiliary materials for automated steelmaking of a steelmaking converter comprises a batching unit 1, an air inlet pipe 2, an air duct 3 and a discharge pipe 4. The batching unit 1 comprises a material leakage sleeve 5 and an air jet shaft 6. The air duct 3 is provided with an air guide box 7, which is a hollow cylinder. The air guide box 7 is provided with a first rotating shaft 8, and the first rotating shaft 8 is fixedly provided with a fan blade 9 matching the air guide box 7.

[0026] The basic function of this equipment is the same as that of the utility model patent named "A uniform feeding device for raw and auxiliary materials for steelmaking" (application number 202120745348.9). The material is put into the batching unit 1, and the leakage sleeve 5 is evenly distributed. The gas enters the air duct 3, the discharge pipe 4 and the jet shaft 6 from the air inlet pipe 2. The impact of the gas at the jet shaft 6 sprays the material from the leakage sleeve 5 and discharges it from the discharge pipe 4; it is worth noting that first, the gas enters the air inlet pipe 2 and the air duct 3, and then the gas enters the air guide box 7. The gas flow drives the fan blades 9 to rotate, and the rotation of the fan blades 9 causes the first rotating shaft 8 to rotate. The rotation of the first rotating shaft 8 drives the driving gear 10 to rotate, so the transmission chain 11 moves, and the movement of the transmission chain 11 causes the driven gear 14 to rotate. The movement of the driven gear 14 drives the second rotating shaft 13 to rotate, and the rotation of the second rotating shaft 13 causes the driving bevel gear 16 to rotate, and the rotation of the driving bevel gear 16 causes the driven bevel gear 15 to rotate, so the leakage sleeve 5 rotates, thereby achieving the effect of saving energy and being more green and environmentally friendly.

[0027] Preferably, a sealing rubber ring is provided at the contact point between the air guide box 7 and the first rotating shaft 8. Such a structural design makes the equipment sealing effect better and ensures the normal and stable operation of the equipment.

[0028] Preferably, a rubber cushion is provided at the contact point between the fan blade 9 and the air guide box 7. Such a structural design reduces the friction damage to the fan blade 9 and prolongs the service life of the equipment.

[0029] Preferably, a sealing rubber ring is provided at the contact point between the air duct 3 and the air guide box 7. Such a structural design makes the equipment more sealed and ensures the normal and stable operation of the equipment.

[0030] Preferably, a sealing rubber ring is provided at the contact point between the leakage sleeve 5 and the jet shaft 6. Such a structural design makes the equipment sealing effect better and ensures the normal and stable operation of the equipment.

[0031] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
