Problems solved by technology
The heating process not only increases energy consumption, but also the equipment needs to be equipped with a corresponding heating system, which increases input costs and maintenance costs
In addition, the lye needs to be replaced frequently, otherwise the decontamination ability will decrease

Embodiment 1
[0022] The strip cleaning method of the oriented silicon steel sheet of the present invention comprises brush cleaning, clear water rinsing, wringing treatment with a drying roller and subsequent drying treatment after the oriented silicon steel strip is uncoiled. In the cleaning method of the present invention, the biological enzyme degreasing agent solution is used to scrub the oriented silicon steel strip. The biological enzyme degreasing agent includes biological enzymes, surfactants, metal ion chelating agents, organic bases and degreasing emulsifiers. When in use, add the biological enzyme degreasing agent to the preparation tank, add water to stir and dissolve, put it into the scrubbing tank, and start production after 5-10 minutes of circulation, and the running speed of the steel strip during cleaning can be set according to the needs of the production line, such as The decarburization annealing line can be set at 10-18m / min, and the magnesium oxide coating line can be...

Abstract
The invention relates to a cleaning method of plate strips, in particular to a production method of a rolling-back connection titanium aluminum titanium metal composite material. The method comprises brush rolling and cleaning, clean water rinsing, squeezing roller squeezing treatment and subsequent drying treatment of uncoiled oriented silicon steel; during brush rolling and cleaning, a biological enzyme degreasant solution is adopted to clean a steel strip; a biological enzyme degreasant is adopted to replace an alkaline degreasant to carry out surface cleaning treatment on the oriented silicon steel strip, heating and electrolytic degreasing are not needed, energy is saved, consumption is reduced, and the production cost is greatly reduced; in addition, the PH value of the cleaning liquid is alkalescence, due to adoption of biological enzyme and a surface active agent, biodegradation is easy, the sewage discharge is relieved, after flocculating settling, sewage water can be continuously used, water resources are saved, and environment-friendly performance is high; and the cleaning liquid further has the beneficial effects of being good in emulsifying ability, high in seepage force, good in enzyme biological decomposition, high in oil removal performance and the like, and the cleaning efficiency is high.
Description
technical field [0001] The invention relates to a strip cleaning method, in particular to a strip cleaning method for oriented silicon steel sheets. Background technique [0002] Oriented silicon steel, also known as cold-rolled transformer steel, is an important ferrosilicon alloy used in the manufacture of transformer cores. Due to its complex production process, strict manufacturing technology, long process and many influencing factors, it has always been a top product in the steel industry. It is known as steel artwork. [0003] The surface quality and performance of grain-oriented silicon steel directly determine its price. In the intermediate process of oriented silicon steel, it needs to be decarburized and coated with magnesia. Before this, the oil stains and emulsions on the surface must be cleaned, otherwise the decarburization effect will be affected or the magnesia coating will be uneven and easy to fall off. Moreover, the heating furnace will be polluted. The...
