Description

Technical Field

[0001] The utility model relates to the technical field of converters, in particular to an energy-saving converter. Background Art

[0002] The converter is a common piece of equipment used for metal smelting. During blowing, the converter is heated by chemical reaction heat, requiring no external heat source. The primary oxidant required for this chemical reaction is oxygen. Most existing converters are top-blown oxygen converters, where an air lance is inserted from the top of the converter to inject air into the converter.

[0003] The existing referenceable Chinese utility model patent has the announcement number CN207006834U, which discloses an energy-saving converter, which includes a converter body, a foundation, a nozzle assembly, a duct assembly, an air compressor and a blower. The converter body is arranged in the foundation, and the nozzle assembly is plugged into the converter body. The air compressor and the blower are connected to the nozzle assembly through the duct assembly, and the ratio of the air compressor to the blower is 1:3. The nozzle assembly includes a nozzle body and a nozzle, and the nozzle body includes an inlet section, a contraction section, a throat and a diffusion section in sequence, and the length of the contraction section is greater than the length of the diffusion section. The nozzle is fixedly connected to the tail of the diffusion section by a thread, and the nozzle is a hollow hemispherical shell structure. A number of nozzle holes are evenly distributed on the spherical surface of the nozzle, and the cross section of the nozzle hole is an isosceles trapezoid, and the large end face of the nozzle hole is close to the center of the nozzle sphere. This project achieves the goal of saving energy by setting up a blower and air compressor in a ratio of 3:1. The nozzle body adopts a throttling injection structure, which can increase the pressure of the air sprayed into the furnace body, thereby improving the chemical reaction efficiency in the furnace body.

[0004] The existing converter has no external insulation structure, and the internal heat will be lost through the furnace body, which requires continuous high-intensity heating of the converter to ensure the quality of the molten steel. At the same time, after the converter completes steelmaking, the heat of the furnace body will be quickly lost, resulting in energy waste. Utility Model Content
