Problems solved by technology
At the same time, the oxygen lance body and water cooling box of the oxygen lance are very close to the hot molten steel in the furnace, and are subject to strong thermal radiation. The oxygen lance body and water cooling box are often severely burned, and production accidents such as water leakage and gun burning occur. Affect the service life of the oxygen lance structure, and affect the normal progress of iron and steel smelting

The invention provides an electric arc furnace oxygen gun structure applied to the technical field of electric arc furnaces for special steel smelting. A water cooling box (1) of the electric arc furnace oxygen gun structure comprises a plurality of blocky water cooling box components (3), cooling water ways (4) are arranged in the water cooling box components (3), and are communicated in each water in each cooling box component (3), and a cavity (5) between the water cooling box components (3) is sleeved with an oxygen gun body (2). The electric arc furnace oxygen gun structure is simple and low in manufacturing cost, through structural improvement, the water cooling box can be reliably cooled through cooling water, the water cooling box can be prevented from being damaged by fire, reliable work of the oxygen gun structure is ensured, meanwhile, fire leaking and blasting phenomena can be effectively prevented from appearing in the combination portion of the oxygen gun body and the water cooling box, an oxygen gun tube can be effectively prevented from being damaged by fire, the service life of the oxygen gun structure can be finally prolonged, and production of the electric arc furnace is stabilized.
Description
technical field [0001] The invention belongs to the technical field of an electric arc furnace for special steel smelting, and more specifically relates to an oxygen lance structure of an electric arc furnace. Background technique [0002] At present, electric arc furnaces are widely used in the field of special steel smelting. In electric arc furnace steelmaking, oxygen lances are mainly used to inject oxygen for decarburization and heating. Since the atmosphere in the electric arc furnace is in a positive pressure state during normal smelting, and the oxygen lance body of the oxygen lance structure and the water cooling box are sealed as a flat seal, if the seal is not tight, fire leakage and blasting will occur. At the same time, the oxygen lance body and water cooling box of the oxygen lance are very close to the hot molten steel in the furnace, and are subject to strong thermal radiation. The oxygen lance body and water cooling box are often severely burned, and produc...
