Detailed Description
The utility model discloses electric arc furnace smoke and dust remote control atmoseal device includes atmoseal ring 1, metal collapsible tube 2, flow control valve 3, air supply pipe 4 and computer 5. The air seal ring 1 is a closed circular ring, air injection holes which are obliquely arranged downwards are densely distributed in the inner ring of the circular ring, 3 mutually communicated air seal rings 1 form an air seal ring group with a three-ring structure, one air seal ring 1 is connected with a metal hose 2, and the other end of the metal hose 2 is connected onto an air source pipeline through a flow regulating valve 3 and an air source pipe 4. The flow control valve 3 is connected with a computer 5, and the opening, closing and operation of the flow control valve 3 are controlled through the picture of the computer 5. The gas seal ring group of the gas seal device 6 is arranged at the circular lining 8 of the water-cooling furnace cover of the electric arc furnace.
The gas source pipeline comprises a compressed air pipeline, a nitrogen pipeline or an argon pipeline, so that the gas sealing device 6 can be switched into compressed air or argon according to the requirement of smelting steel.
The flow regulating valve 3 is automatically interlocked with the electrode of the electric arc furnace, the air seal device is automatically opened when the electric arc furnace is heated, and is automatically closed when the electric arc furnace is not heated, thereby saving energy.
