Cold rolled silicon steel plate cleaner

Abstract

The invention discloses a cold rolled silicon steel plate cleaner, and aims at providing a cleaner for a cold rolled silicon steel plate, which is good in cleaning effect, small in energy consumption and slight in pollution degree. The cold rolled silicon steel plate cleaner mainly comprises the following components in parts by weight: 41-55 parts of sodium hydroxide, 19-30 parts of sodium silicate, 10-24 parts of sodium tripolyphosphate, 24-33 parts of sodium carbonate, 7-12 parts of polyoxyethylene ether, 4-7 parts of soap, 0.25-0.4 part of an efficient organic silicon suppression foam agent, and 0.25-0.4 part of universal silicone foam powder. The cold rolled silicon steel plate cleaner is applicable to the cleaning of the silicon steel plate.

Description

Technical field [0001] The invention relates to the technical field of cleaning of metal materials, in particular to a cold-rolled silicon steel plate cleaning agent. Background technique [0002] Because the silicon steel plate needs to use rolling oil during the cold rolling process, a layer of oil stains adhere to the surface of the cold rolled silicon steel plate. This layer of oil stain must be cleaned before annealing to prevent the silicon steel plate from being carbonized during the annealing process. 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 often cleaned with alkaline cleaning agents. However, these cleaning agents are not effective in cleaning cold-rolled silicon steel sheets. The surface of cold-rolled silicon steel sheets after cleaning is often still attached with a layer of oil stains, resulting in the formation of carbon stains on the surface of c...

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. The quality of the surface, and 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.
