Abstract

The invention discloses an efficient impurity removal device for a medium-frequency induction smelting furnace. The efficient impurity removal device comprises a fixing frame, a furnace body and a base. The inner wall of the base is fixedly connected with the furnace body. An argon blowing module is fixedly mounted on the lower surface of the furnace body and communicates with the interior of thefurnace body. The fixing frame is fixedly connected to the side wall, close to the top, of the furnace body. An air cylinder is fixed to the center of the top of the fixing frame. The output end of the air cylinder is fixedly connected with a supporting rod. A fishing disc is arranged on the outer side of a rotating rod in a sleeving mode. An impurity detection mechanism is arranged in the fixingframe. A control panel is fixedly mounted at the upper end of the side wall of the fixing frame. A drying mechanism is fixed to the side wall of the fixing frame and located below the control panel. According to the efficient impurity removal device, the rolling degree of molten steel is comprehensively judged through the rotating speed of the fishing disc and the inclination angle state of a hinge rod, the detection precision is effectively improved, formed solid inclusions are prevented from being refined, and thus, the impurity removal effect is improved.

Description

technical field [0001] The invention relates to the technical field of intermediate frequency induction melting furnaces, in particular to an efficient impurity removal device for intermediate frequency induction melting furnaces. Background technique [0002] At present, for steelmaking in medium frequency induction melting furnaces, the method of blowing argon at the bottom of the furnace is generally used to remove impurities from the molten steel. In addition to a certain air permeability, the brick must also be able to withstand the erosion of molten steel, have a certain high temperature strength and good resistance to rapid cooling and rapid heating, and generally use high-alumina bricks; the pH2 and pN2 in the blown argon bubbles are close to zero. The hydrogen and nitrogen dissolved in the molten steel enter into the argon bubbles and are carried out. The oxygen in the molten steel, including dissolved oxygen and oxide inclusions, is produced in the process of blowi...
