The invention relates to an electrode lifting and rotary stirring device in electromagnetic-induction mineral slag smelting furnace. A plurality of induction heating electrodes are fixed on an electrode fixing plate; the electrode fixing plate is fixed on the outer circle of an electrode rotary support, wherein the outer circle of the electrode rotary support is provided with a gear; the inner circle of the electrode rotary support is fixed on the arm of the cover of the furnace; two ends of a ball screw are respectively fixed on an electrode lifting and fixing column through bearings with bases; the but of the ball screw is fixed on the arm of the cover of the furnace; and a lifting arm is sleeved on the electrode lifting and fixing column through eight front and rear rolling wheels. The electrode lifting and rotary stirring device is simple in structure and reasonable in design, ensures that the electromagnetic-induction mineral slag smelting furnace can be used for the shortened process of producing mineral wool and effectively solves the problems in the prior art that the hot blast furnace slag is difficult to increase temperature and temper so that the thermal efficiency and the short-process production flexibility of the smelting furnace are improved, the production efficiency is improved, the energy consumption is reduced by 40% and the product cost is lowered by 15%.
Description
Technical field [0001] The invention relates to an electrode lifting and rotating stirring device in an electromagnetic induction slag furnace for producing mineral wool in a short process. It belongs to the technical field of producing mineral wool from an electromagnetic induction slag furnace. Background technique [0002] As the main force in the process of industrialization, the steel industry also faces opportunities and challenges. The energy consumption of the blast furnace ironmaking process accounts for 60% of the total energy consumption of the iron and steel industry. It is a large energy consumer in the iron and steel industry, and its energy saving and emission reduction potential is huge. Blast furnace slag is a kind of solid waste discharged from blast furnace ironmaking. Its treatment process not only consumes a lot of energy, but also emits a lot of harmful substances. Therefore, it is necessary to carry out research on the recycling of blast furnace slag, whi...
