Abstract

The invention discloses a cold-rolled silicon steel normal-temperature zero-release oil removal agent. The oil removal agent is prepared from 100-150 parts by weight of organic bionic acid, 80-120 parts by weight of a biological ferment, 10-30 parts by weight of a bio-enzyme, 5-10 parts by weight of a surfactant and 5-10 parts by weight of a sterilization algicide. The oil removal agent does not contain phosphorus, sodium and other metal ions, does not contain persistent organic pollutants, can undergo a decomposition reaction with acid, base, oil and ferric oxide, brightens the cleaned product and produces the final decomposition products such as water and carbon dioxide. The oil removal agent does not contain any metal ions. The cleaned metal ions and calcium and magnesium ions are complexed and do not produce precipitates so that the silicon steel cleaning spray water and a cleaning agent diluent can be recycled until thorough natural consumption. The oil removal agent has a strong ion complexing capacity, hardly produces precipitates, has a strong effect of cleaning water scales and blue-green algae of a cleaning tank and does not produce built-up edges on a cleaning roller, a driving roller and a magnesium oxide coated roller.

Description

technical field [0001] The invention relates to a degreasing agent, in particular to a normal temperature zero-emission degreasing agent for silicon steel rolling and a preparation method thereof. Background technique [0002] Cold-rolled silicon steel (also known as electrical steel) is known as a "handicraft" in steel products, and has very strict requirements on the surface of the product. After the silicon steel strip is cold-rolled, there are a lot of residues on the surface of the steel strip, mainly oil, iron oxide powder, and loose impurities. If these residues are not cleaned, it will cause great harm to the performance of the silicon steel. After the magnesium oxide coating enters the bell furnace and heats up, it is easy to form black spots and water spots on the surface of the silicon steel strip. In addition, the sticky matter and iron oxide powder left when the surface of the steel strip is not cleaned will form nodules on the surface of the hearth roll. Prod...
