Embodiment Construction

[0026] Such as figure 1 , figure 2 with image 3 As shown, the double-chamber steelmaking device of the present invention includes two smelting chambers, and the tops of the smelting chambers communicate with each other. Each smelting chamber includes a furnace 1, and the molten steel outlet 2 of the furnace 1 is arranged on one side of the rear wall 3 of the smelting chamber; Wall 6, the top of side wall 6 is also equipped with gas-oxygen burner 7 for secondary combustion of carbon monoxide contained in the waste gas, front wall 8, two feed ports 9 installed on the front wall 8, so The horizontal height of the lowest part of the feed inlet 9 is +9400mm, and it is located between the two feed inlets for processing the slag treatment port 10. Each melting chamber has a smelting chamber that can rotate the melting chamber around its horizontal axis. A device 11 with which the melting chamber can be inclined to an angle of 45° relative to its horizontal axis to the front or r...

Abstract

The invention pertains to the art of ferrous metallurgy, and more particularly, to a multichambered steelmaking apparatus and to a method of steelmaking. A multichambered steelmaking apparatus contains smelting chambers communicating with each other through their upper portions. Process input ports are provided in the chamber side wall, and the smelting chambers are provided with gas-oxygen burners installed on the walls of the smelting chambers facing each other. A method of steel making employs the apparatus in a unique manner. During operation, the smelting chambers are tilted in the direction of the input port and during the discharge of steel they are tilted in the direction of the outlet. During the melting stage carbon monoxide (CO) is afterburned by gas-oxygen burners forming carbon dioxide (CO) in the exit gasses supplied to the gas exhaust system through the coaxial chamber. A portion of a slag from the previous heat is retained.

Description

technical field [0001] The invention relates to the technical field of iron smelting, and more specifically, relates to a double-chamber steelmaking device and a steelmaking method using the device. Background technique [0002] The existing multi-chamber steelmaking device includes a plurality of smelting chambers, and each smelting chamber communicates with each other through the top. Each smelting chamber includes two feed ports for adding metal charge and pouring molten iron, and the feed ports are located at the front of the smelting chamber. There is a slag treatment port between the two feed ports. The hearth in each smelting chamber has a molten steel outlet again. And there are some wedge-shaped holes on the top of the melting chamber to connect the oxygen supply pipeline to the operating area. The upper part of the front wall of the melting chamber, that is, the part above the bottom of the feed inlet, has a certain inclination angle to the rear wall relative to...
