Problems solved by technology

[0003] However, the existing converter generally does not have its own rotating device. When rotating, the bottom of the converter needs to be pulled by the hoisting device to realize its own rotation. The operation is cumbersome and has a large safety hazard; The method has low oxidation efficiency to molten steel

Abstract

The invention discloses an oxygen-enriched side blowing smelting converter, and belongs to the field of smelter equipment. The oxygen-enriched side blowing smelting converter comprises a main converter body, a rotating device, supports and a side blowing device; the rotating device comprises a box, a gear, a rotating shaft, a rack and a hydraulic cylinder; and the side blowing device comprises three side blowing plates, a gas inlet passage and a gas inlet pipe, wherein the gas inlet passage is arranged at the top parts of the side blowing plates. According to the oxygen-enriched side blowing smelting converter disclosed by the invention, by installing the rotating device, the main converter body can rotate without using lifting equipment, and use safety is enhanced; by installing the sideblowing device, oxygen high in concentration is blown into the side part of molten steel, so that the molten steel located in the main converter body can be fully oxidized; and therefore, the oxygen-enriched side blowing smelting converter is capable of realizing rotation of the main converter body, is convenient to operate and high in safety, and has a good oxidation effect on the molten steel.

Description

technical field [0001] The invention relates to the field of furnace equipment, and more specifically, to an oxygen-enriched side-blown smelting converter. Background technique [0002] Converter (converter), the furnace body can be rotated, and is used for metallurgical furnaces for blowing steel or blowing matte. The furnace body of the converter is made of steel plate, which is cylindrical and lined with refractory materials. It is heated by chemical reaction heat during blowing and does not require an external heating source. It is the most important steelmaking equipment and can also be used for copper and nickel smelting. According to the refractory properties of the lining, the converter is divided into alkaline (with magnesia or dolomite as the lining) and acidic (with silicon material as the lining) converter; according to the part where the gas is blown into the furnace, it is divided into bottom blowing and top blowing. And side blowing converter; according to th...
