Problems solved by technology

However, these cleaning agents do not have a good cleaning effect on cold-rolled silicon steel sheets. A layer of oil stains often adhere to the surface of cold-rolled silicon steel sheets after cleaning, causing carbonaceous stains to form on the surface of cold-rolled silicon steel sheets after annealing, seriously affecting the quality of the steel sheets. surface quality
Moreover, the working temperature of these cleaning agents is high, the energy consumption is large during cleaning, and it is easy to cause fouling of equipment and pipelines and block the pipelines, affecting normal production
In addition, these cleaning agents do not contain defoaming agents, and a large amount of foam will be generated during the cleaning process of cold-rolled silicon steel plates. These foams will pollute the working environment in light cases, and cause production to fail in severe cases.
[0004] In the process of realizing the present invention, the inventor found that the prior art at least has defects such as poor cleaning effect, high energy consumption, and easy operation failures.

Abstract

The invention discloses a cleaning agent for a cold rolled silicon steel plate; the cleaning agent mainly comprises the following components in parts by weight: 16-30 parts of sodium hydroxide, 42-58 parts of sodium silicate, 13-19 parts of sodium tripolyphosphate, 2-12 parts of low-carbon-chain fatty alcohol ether, and 0.3-0.8 parts of high-temperature strong base organic silicon de-foaming power. The cleaning agent for the cold rolled silicon steel plate, provided by the invention, can overcome the defects of poor cleaning effect, high energy consumption, easily occurrence of operation faults and the like, and has the advantages that the cleaning effect is excellent, the energy consumption is low, and the operation fault is not easy to cause.

Description

technical field [0001] The invention relates to the technical field of metal material cleaning, in particular to a cleaning agent for cold-rolled silicon steel sheets. Background technique [0002] Since the silicon steel plate uses rolling oil during the cold rolling process, a layer of oil stains sticks to the surface of the cold rolled silicon steel plate. Cause pollution and affect the coating quality of subsequent processes. [0003] Generally, the oil stains on the surface of cold-rolled silicon steel sheets are usually cleaned with alkaline cleaning agents. However, these cleaning agents do not have a good cleaning effect on cold-rolled silicon steel sheets. A layer of oil stains often adhere to the surface of cold-rolled silicon steel sheets after cleaning, causing carbonaceous stains to form on the surface of cold-rolled silicon steel sheets after annealing, seriously affecting the quality of the steel sheets. Surface quality. Moreover, the working temperature of...
