There are significant differences in the manufacturing process and product characteristics between pickled plates and hot-rolled plates, as follows:
hot rolled plate
Manufacturing process:
Hot rolled plate is made by heating billet at high temperatures (usually over 1700°F or 927°C) and rolling it through a rolling mill into thin plate.
After hot rolling, the steel is cooled and then cut to the required size and thickness.
Features:
The surface is relatively rough, with obvious oxide scales and scales.
Dimensional accuracy is lower, but toughness and ductility are better.
Suitable for applications where strict surface quality is not required, such as construction and shipbuilding.
pickling board
Manufacturing process:
Pickled plates are pickled on the basis of hot-rolled plates, using an acidic solution to remove oxide scales and scales on the surface.
Passivation treatment can also be performed after pickling to further improve surface quality and corrosion resistance.
Features:
The surface finish is high, no oxide scale, and smooth.
The dimensional accuracy is higher and the shape and thickness are more uniform.
More suitable for applications requiring better surface quality, such as automotive manufacturing, home appliances and precision instruments.
Summarize
Hot rolled plate: rough surface, suitable for areas that do not require high surface quality, low price.
Pickled board: The surface is smooth, suitable for fields with higher requirements on surface quality, and the price is higher.
This difference makes them have advantages in different industries and application scenarios.
