High temperature flue gate, combustion furnace device with high temperature flue gate and manufacturing method of high temperature flue gate

Abstract

The invention discloses a high temperature flue gate. The high temperature flue gate comprises at least one gate plate assembly, at least two first pipe bodies and at least one second pipe body, wherein the gate plate assembly comprises a first gate plate unit and two second gate plate units, and is rectangular; the two second gate plate units are detachably connected to the two sides of the first gate plate unit, and each of the first gate plate unit and the second gate plate units is internally provided with a metal plate mesh layer and a high-aluminum material layer; the at least two first pipe bodies are arranged in the gate plate assembly in a penetrating manner, and the bottoms of the first pipe bodies are fixedly arranged in the gate plate assembly; and the at least one second pipe body is perpendicular to the first pipe bodies and is arranged on the tops of the first pipe bodies in a sleeving manner. Meanwhile, the invention discloses a combustion furnace device with the high temperature flue gate and a manufacturing method of the high temperature flue gate. Compared with the prior art, the performance of high temperature resistance and corrosion resistance can be effectively improved.

Description

technical field [0001] The invention relates to a flue gate applied to combustion furnaces such as smelting furnaces and holding furnaces, in particular to a high-temperature flue gate and its combustion furnace device and preparation method. Background technique [0002] For combustion furnaces such as smelting furnaces and holding furnaces in aluminum processing and other industries, the high-temperature flue gate is an indispensable part. It is the discharge channel for high-temperature flue gas generated after fuel combustion. Whether it works normally or not affects For the normal operation of the furnace, the specific indicators are production capacity, unit energy consumption and the stability of production operation (stable furnace pressure), etc. Therefore, the high-temperature flue gate is a key component of a fuel furnace. [0003] The earliest high-temperature flue gates were made of cast iron, but their service life was extremely short, and they often burned out...

Problems solved by technology

[0004] After that, water-cooled rams were used, and the problem of operating temperature can be solved, but the corrosion resistance performance is still not good, and the problem is still not solved.
