Description

каналам 7 в камеру плавлени 1. По мере наплавлени флюса в камере плавлени 1 он под действием т жести столба флюса поступает по каналам 6 в камеры-газлифты 2. Таким образом, осуществл етс циркул ци флюса внутри печи, во врем которой он продолжает нагреватьс . По достижении определенной температуры флюса начинают загружать металл в плавильную камеру 1 через загрузочное устройство 5. Металл, проход через слой флюса, расплавл етс и одновременно рафинируетс . По мере накоплени жидкого металла в камере 1 он выпускаетс через шпуровое отверстие 8. Отход щие газы после перетекани флюса из камер-газлифтов 2 в камеру плавлени 1 удал ютс через газоход 4. При этом теило отход щих газов утилизируетс на подогрев щихты.channels 7 into the melting chamber 1. As the flux is deposited in the melting chamber 1, it undergoes the flux of gravity through the channels 6 into the gas lift chambers 2. Thus, the flux is circulated inside the furnace, during which it continues to heat up. Upon reaching a certain temperature, the flux begins to load the metal into the melting chamber 1 through the charging device 5. The metal, passing through the flux layer, melts and refines at the same time. As the liquid metal accumulates in chamber 1, it is discharged through a bore hole 8. Exhaust gases after the flux flows from the gas lift chambers 2 to the melting chamber 1 are removed through the duct 4. At the same time, the waste gas is recycled to the preheaters.

Claims

1. Furnace for flare-slag remelting, including lined melting

a chamber, a burner for burning fuel, a charging device, a flue duct and a bore hole, characterized in that, in order to reduce the degree of oxidation of metals by isolating it from the gas phase, the furnace is equipped with gas lift chambers, the lining of the furnace is made in the furnace lining -gas lifts and the melting chamber at the top and bottom and located tangentially relative to them, the upper channels are horizontal, the lower ones are inclined towards the melting chamber, and the burners for fuel combustion are installed tangentially in the chamber rax-gas lift and iodine angle to the vertical axis.

2. The furnace according to claim 1, characterized in that the ratio of the diameters of the melting chamber and the gas-chamber chambers is taken within.

3. Bake by and. 1, characterized in that the chambers of the gas-chamber chambers are made inclined towards the lower channels, and under the melting chamber they are inclined towards the screw hole.
