Integral structure of oxygen muzzle bricks of colored smelting furnace

Abstract

The invention discloses an integral structure of oxygen muzzle bricks of a colored smelting furnace. The integral structure comprises two oppositely-arranged surrounding bricks, a groove is formed inthe side wall of each of the two surrounding bricks, an oxygen muzzle brick is arranged in each groove, and a nozzle is formed in each oxygen muzzle brick; two limiting blocks are fixed to the side wall of one of the surrounding bricks, and the two limiting blocks are arranged on the two sides of the corresponding oxygen muzzle brick correspondingly; limiting grooves matched with the limiting blocks are formed in the side wall of the other surrounding brick, fixing grooves are formed in the side walls of the two sides of the two surrounding bricks, and a fixing mechanism is arranged in each fixing groove; and telescopic mechanisms are transversely arranged on the two sides of the two surrounding bricks, and the two ends of the telescopic mechanisms are fixedly connected to the fixing mechanisms through connecting blocks. According to the integral structure, the grooves formed by the two surrounding bricks are used for fixing the oxygen muzzle bricks so as to ensure the stability of theoxygen muzzle bricks, and the telescopic mechanisms are used for adjusting the fixing mechanisms so that the two surrounding bricks can be connected together through the fixing mechanisms, and detaching and mounting are facilitated.

Description

technical field [0001] The invention relates to the technical field of smelting equipment, in particular to an overall structure of an oxygen muzzle brick of a nonferrous smelting furnace. Background technique [0002] A smelting furnace refers to a furnace that melts iron ore, such as melting hematite (Fe2O3) or magnetite (Fe3O4), to turn it into pig iron. The furnace body is a tall columnar structure lined with refractory material, filled from the top with washed ore, coke and solvent (the solvent is usually limestone). [0003] The non-ferrous smelting furnace needs to use the oxygen blowing lance to blow oxygen into the furnace during the smelting process. In order to maintain the stability of the oxygen blowing lance, it is necessary to use surrounding bricks to fix the oxygen muzzle brick. The oxygen blowing lance is placed in the oxygen muzzle brick, but The existing surrounding bricks surrounding the oxygen gun muzzle bricks are all tied up with iron wires, and the ...

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
