Integral structure of oxygen gun muzzle brick of a non-ferrous smelting furnace

Abstract

The invention discloses an overall structure of an oxygen muzzle brick of a non-ferrous smelting furnace, which comprises two surrounding bricks arranged oppositely, grooves are opened on the side walls of the two surrounding bricks, and oxygen muzzles are arranged in the grooves Bricks, and a spout is opened on the oxygen gun muzzle brick, and two limit blocks are fixed on the side wall of one of the surrounding bricks, and the two limit blocks are respectively located on both sides of the oxygen gun muzzle brick, and the other said The side walls of the surrounding bricks are provided with limiting grooves matching the limiting blocks, and the side walls on both sides of the two surrounding bricks are provided with fixing grooves, and a fixing mechanism is provided in the fixing grooves. Both sides are horizontally provided with a telescopic mechanism, and both ends of the telescopic mechanism are fixedly connected with the fixing mechanism through a connecting block. The invention utilizes the groove formed by two surrounding bricks to fix the oxygen muzzle brick to ensure the stability of the oxygen muzzle brick, and uses a telescopic mechanism to adjust the fixing mechanism so that the fixing mechanism can connect the two surrounding bricks together , easy to disassemble and install.

Description

Technical field [0001] The present invention relates to the technical field of smelting equipment, and more particularly to an overall structure of a colored smelting furnace oxygen guideline. Background technique [0002] The smelting furnace refers to the refining furnace of the iron ore, such as melting hematite (Fe2O3) or magnetite (Fe3O4), so that it becomes a pig iron. Such a furnace is a highly column structure of the refractory lining, which is filled with washing ore, coke and solvent from the top end (solvent usually limestone). [0003] In the process of smelting, the non-ferrous smelting furnace needs to use the airborne gun to blow an oxygen in the furnace. In order to maintain the stability of the blower gun, the oxygen gun is needed to fix the oxygen gun, and the oxygen gun is placed in the oxygen gun, but The existing bricks around the oxygen guns are bundled with wire, and the wire is long, which is easy to firing, thus causing damage to the lacera and oxygen gun...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem in the prior art, but the existing bricks surrounding the oxygen gun muzzle bricks are all tied up with iron wires. After a long time, the iron wires are easy to burn and break, resulting in the surrounding bricks and oxygen gun muzzle bricks. Drop damage problem, and proposed a kind of overall structure of oxygen muzzle brick of non-ferrous smelting furnace
