摘要： A sealed feeder device utilized in an electric arc furnace (1), and a flue gas and temperature control method. The sealed feeder device comprises a sealed feeding chute (5) having an outlet sealedly communicating with a side wall of the electric arc furnace (1), and a material blocking sealed arc-shaped door (3) disposed in the sealed feeding chute (5). The material blocking sealed arc-shaped door (3) separates the sealed feeding chute (5) into a cold steel scrap storage chamber (18) and a material feeding and dedusting chamber (2), and is operated by a driving mechanism (34) to separate or connect the cold steel scrap storage chamber (18) and the material feeding and dedusting chamber (2). The method comprises: adopting the feeder device to divide the flue gas of the electric arc furnace (1) into two paths, and controlling, by a flue gas adjustment device (16), a ratio of a flue gas flow from a flow-splitting dust removal pipe (11) to that from a dust removal pipe (4) to obtain a required flue gas mixture temperature.

摘要： The present invention discloses a tipping hopper, comprising a hopper body, hopper rotating supports and a tipping mechanism. The tipping mechanism comprises a connecting rod and a crank. One end of the connecting rod is hinged on the hopper body, and the other end is hinged with one end of the crank; and the other end of the crank is hinged on a crank rotating support through a crank rotating shaft. By optimizing a crank starting point and a crank end point, ensure hopper's position of receiving and discharging material is arranged at or near a dead point of the tipping mechanism so that the working condition of an impact force borne by a speed reducer device is optimized when the tipping hopper is charged and discharged. The mechanism also optimizes the position of the center of gravity of the hopper body and the position of the center of gravity of a charged hopper, so that the center of gravity of the hopper body is located between a hopper rotating hinge point and the connecting rod support hinge point near the hopper rotating hinge point. A force amplification effect of the connecting rod is used to greatly reduce the requirement for the output moment of the speed reducer, thereby greatly reducing the weight of the speed reducer device and the power of a tipping motor and saving motor power and energy consumption of a hoisting system.

摘要： The present invention discloses a scrap steel preheating type electric arc furnace and a method for improving a heating cold region of a side wall charging electric arc furnace. The scrap steel preheating type electric arc furnace includes an electric arc furnace body and an inclined scrap steel preheating chamber. An included angle between the scrap steel preheating chamber and a horizontal plane is 30° to 65°. The scrap steel preheating chamber is connected with the electric arc furnace body. A dust removal pipe chamber is arranged at an upper end. A material blocking tooth rake is arranged on the scrap steel preheating chamber. A driving mechanism is arranged below the material blocking tooth rake. Flue gas enters the scrap steel preheating chamber, penetrates through the material blocking tooth rake and the scrap steel and is sucked out by the dust removal pipe chamber. The scrap steel is preheated; then, the material blocking tooth rake is opened; and the preheated scrap steel slides to a center of the electric arc furnace body along a slot bottom of the inclined scrap steel preheating chamber. A falling angle of the scrap steel is changed through a method of matching the scrap steel preheating chamber with a large inclined angle and the material blocking tooth rake, thereby overcoming a problem of lateral stacking of the side wall charging electric arc furnace, reducing impact force of the scrap steel to the device and greatly enhancing reliability of the device.

摘要： An arc furnace automatic feeding device comprises an automatic distributing device, wherein the automatic distributing device comprises a distributing groove, and at least one step-like distributing section which tilts from high to low along a material delivery direction is provided at the bottom of the distributing groove; and further comprises a thermal feeding device, a feeding device, and an uploading device. The automatic distributing device enables forward tossing of the materials when falling down, which eliminates the problem that the materials are difficult to be scattered in overall movement, so that the materials can be effectively scattered by vibration, the stacked materials can be uniformly and continuously distributed in the groove, and the waste steel piling problem of the materials is prevented from occurring at a throat portion of the feeding device. Different thermal feeding devices have advantages such as good material preheating effect and environment friendliness. The uploading device does not require a crane, so the operation is convenient, of high safety, and suitable for high-frequency material uploading; and the uploading device can satisfy operation frequency demands of continuous feeding for smelting of medium to large arc furnaces.
