Description

Technical Field

[0001] The utility model relates to the technical field of furnace covers, in particular to a movable dry furnace cover of an iron-making electric furnace. Background Art

[0002] An electric furnace is a heating furnace that converts the electrical energy in the furnace into heat to heat the workpiece. Compared with a fuel furnace, the advantages of an electric furnace are: the atmosphere in the furnace is easy to control; the material is heated quickly; the heating temperature is high; the temperature is easy to control; the production process is easier to mechanize and automate; the labor and hygiene conditions are good; the thermal efficiency is high; the product quality is good, and it is more environmentally friendly, which is conducive to alleviating the increasingly serious environmental problems. Refining furnaces mostly use water-cooled furnace hoods to reduce the temperature of the furnace hood and reduce the deformation of the furnace hood. The material cannot be repaired because the metal material deteriorates due to being at high temperature for a long time. The biggest disadvantage of using a water-cooled furnace hood is that if there is a serious leak, an explosion will occur due to water entering the molten iron, which invisibly poses a major safety hazard. There are many ways to open the furnace hood, such as the authorized patent CN202322578105.2, an electric furnace flue gas dust removal device, which uses multiple motors to realize the lifting of the furnace hood. This method uses more components and can also be carried out by dragging. Therefore, in view of the above problems, a dry furnace hood with dragging is proposed. Utility Model Content
