Electric Arc Furnace Covers/Walls:Cooling flue is an important equipment for steelmaking in converter, which has the function of collecting, cooling and conveying flue gas, in addition, the flue is also a waste heat boiler for producing steam.Water-cooled furnace cover, including a large furnace cover and a small furnace cover, the small furnace cover is opened with electrode holes, the small furnace cover is arranged in the center of the large furnace cover, characterized in that: including a protective sleeve, set between the large furnace cover and the small furnace cover, the protective circumference of the wall of the water-cooled circulating pipe, the water-cooled circulating tube is connected to the ends of the water-cooled circulating pipe corresponding to the water inlet pipe, the water return pipe; set in the inner circle of the large furnace cover, and fixed with the large furnace cover, the small furnace cover is set in the protective sleeve Inner ring. Refining furnace water-cooled cover, the water-cooled structure in the cover consists of a number of seamless tubes arranged in close proximity. Each tube is circular in shape. The water-cooled refining furnace cover of this structure is not easy to leak and is easy to maintain.
The main technical solution of the cooling flue is to install cooling fins on the outer wall of the pipe, to connect an outer casing with an outer duct, to connect an axial fan using an air duct at one end of the outer casing, and to install an exhaust port at the other end of the outer casing. Said duct is connected to the outer casing in an inclined shape and the outlet of the duct faces the end of the outer casing on which the exhaust port is installed. A nozzle assembly is connected to the outer casing, the nozzle in the nozzle assembly facing the cavity between the outer casing and the pipe, and the nozzle assembly is connected to the water supply pipe using a receiver.
