Roller zinc-stripping treatment agent for roller

Abstract

The invention discloses a roller zinc-stripping treatment agent. The roller zinc-stripping treatment agent is characterized by comprising the following components in percentage by weight: 20 to 55 percent of NaOH, 1 to 10 percent of stabilizers, 1 to 10 percent of corrosion inhibitors, and is the balance of water. The performance of a roller which is treated by using the roller zinc-stripping treatment agent and a treatment method disclosed by the invention can be restored to be same as that of a new roller, so that the roller can be regenerated and continuously used; and the treatment agent and the treatment method disclosed by the invention can be used for the same roller for many times, thus the service life and the utilization rate of the roller are improved. By adopting the roller zinc-stripping treatment agent and the treatment method disclosed by the invention, the cost of a steel plant can be greatly reduced.

Description

technical field [0001] The invention relates to a roll body dezincification treatment agent. Background technique [0002] The current steel industry has encountered many problems, such as the market’s increasing demand for steel products, the rising price of iron ore, and the requirements of relevant state departments for environmental protection and low-carbon, etc., all of which put forward higher requirements for steel mills in terms of cost control. requirements. [0003] In the production process of cold rolling line in steel mills, hot-dip galvanizing of steel strip accounts for a large proportion. The zinc pot part is the top priority of the whole line. Due to the presence of zinc liquid in the zinc pot, the working environment in the zinc pot is quite harsh. As a result, the main components entering the zinc pot, such as the sinking roll and the surface coating of the stabilizing roll, have a relatively short period of use, generally about 15 to 25 days. The use...

AI Technical Summary

Problems solved by technology

As a result, the main components entering the zinc pot, such as the sinking roller and the surface coating of the stabilizing roller, have a relatively short period of use, generally about 15 to 25 days

The sinking roll and stabilizing roll must be replaced after use, otherwise the quality of the steel strip surface and the quality of galvanizing will be affected, thereby affecting the normal operation of the entire line

[0004] In the prior art, the used sinking rolls and stabilizing rolls are usually discarded and no longer used, resulting in a lot of waste, it is difficult to make full use of the roll body, and the utilization rate of the roll body is low
