Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a method for cleaning an annealing furnace used in the production of stainless steel strips, which can effectively remove impurities such as sealing sand and metal debris in the mesh chain, and can also prevent the mesh chain from rusting And other advantages, it solves the problem that when the mesh chain is used to transport the stainless steel belt, the sealing sand and metal debris will enter the gap of the mesh chain, which will cause the rotation of the mesh chain to be hindered, and in the long-term use process , the contact between the high-temperature mesh chain and the outside air will increase the reaction efficiency between the metal mesh chain and the oxygen in the air, making the mesh chain rust, and the rusted mesh chain will pollute the outside of the stainless steel belt, and it will also increase the movement of the mesh chain When the resistance, resulting in the waste of energy

Abstract

The invention relates to the technical field of stainless steel strip production, and discloses an annealing furnace cleaning method used for stainless steel strip production. The method comprises thefollowing steps that A, a net chain in an annealing furnace used for stainless steel strip production is subjected to flushing and wetting through a water spraying device; B, a cleaning agent used for cleaning is sprayed to the flushed net chain, and the cleaning agent is evenly smeared on the net chain for standing; C, the net chain obtained after standing is subjected to comprehensive cleaningthrough an iron brush, the water spraying device is used for flushing the cleaned net chain, and the cleaning agent on the net chain is completely flushed away until the water on the net chain is notcondensed into water drops or not gathered and flow down. The annealing furnace cleaning method used for stainless steel strip production can flush out seal sand and metal debris in the net chain, thetransmission position of the net chain is prevented from being blocked, efficiency during net chain transmission is kept, the net chain is prevented from being blocked at the bend position, and the production quality and the appearance cleanliness of the stainless steel strip can be kept for a long time.

Description

technical field [0001] The invention relates to the technical field of stainless steel strip production, in particular to a method for cleaning an annealing furnace used for stainless steel strip production. Background technique [0002] Stainless steel refers to steel resistant to weak corrosive media such as air, steam, water, and chemically corrosive media such as acid, alkali, and salt. It is also called stainless acid-resistant steel. In practical applications, the steel resistant to weak corrosion medium is often called stainless steel, and the steel resistant to chemical medium corrosion is called acid-resistant steel. Due to the difference in chemical composition between the two, the former is not necessarily resistant to chemical media corrosion, while the latter is generally stainless. The corrosion resistance of stainless steel depends on the alloying elements contained in the steel. Stainless steel is often divided into martensitic steel, ferritic steel, austeni...
