Generally, our commonly used galvanized steel strip is uniformly plated with a layer of zinc on the base steel surface by electroplating, hot-dip plating, etc., to protect the base steel from corrosion for a long time, and can be used under different conditions. The galvanized steel strip is a corrosion-resistant material and is a commonly used industrial material. Usually, after formation, it will be made into heating pipes, greenhouse pipes, drinking water pipes, etc., which are used in construction, automobile and commercial industries.
The construction industry is used for anti-corrosion building roofs, roofs, etc.; in the automobile industry, it is also used to manufacture corrosion-resistant accessories for cars; secondly, it is mainly used for commercial packaging supplies and materials. According to the different purposes, it is used in the corresponding industry. These industries have one of the essential features: high corrosion resistance, with this feature.
The galvanized steel strip's application effect aligns with expectations and has been widely used in building materials. To enable it to have higher operating efficiency, post-processing of the finished steel strip is an effective and powerful means. Galvanized steel strip has the advantages of corrosion resistance and long service life and has now been widely used.
Now that the galvanized steel strip's development is getting better and better, the competition in the market has become very fierce. The production of products has brought a lot of convenience to our daily lives, so why is this product so popular? Today, I will focus on the advantages of the product in the production process.
When we are in production, we will use machines to produce to increase production speed. In the production process, we can use computers for control, reducing workforce and financial resources. The search for product raw materials is very critical. If the processed product raw materials are easier to find, it can save many things and save the company a lot of costs.
Why does the surface of the cold-rolled steel strip produce black spots? It is mainly because the emulsion is not clean enough to remove so that dark spots will occur after annealing.
The surface roughness of the steel strip:?If the roughness is apparent, the gap between the steel coil layer and the layer interface will increase, which is very beneficial to the emulsion's volatilization.
Annealed substrate chilled coil type: the emulsification volatilization during annealing heating will seriously affect the chilled coil shape's quality. If the steel strip has a wave shape, it will also have a particular impact on the volatilization interlayer emulsion's volatilization.
Residual chloride ions on the steel strip's surface: If it is not cleaned during rinsing, the chloride ions will remain on the surface of the steel strip, which will cause electronic chemical corrosion and produce black Fe304. Emulsion volatility: The emulsion's high-quality thermal volatility can reduce the shortcomings of dark spots on cold-rolled coils. The first coiling tension of the rolled product:
1. Reduce the coiling tension.
2. Increase the gap between the layers.
3.Flow to the distance between the steel coil layers so that the emulsification can be fully volatilized.
