Pickled plate: intermediate product between hot rolled plate and cold rolled plate

The key process flow of hot-rolled pickling plates

The key processes of hot-rolling and pickling boards include metal laser welding machine, position extension straightening, flow field pickling and passivation, online leveling, trimming, online oiling, etc. Angang's pickling and passivation specifications are generally 1.0-6.1*800-1650 mm. The products include low, medium and high toughness grades of steel for stamping dies, steel for automobile structures, etc., which are mainly supplied in the form of coiled steel. Processing characteristics:
Use sulfuric acid to remove the oxide scale on hot-rolled steel to obtain a beautiful, smooth surface. Product features:
1. Reduce costs. Replacing cold-rolled steel plates with pickled plates can save costs for the company.
2. Good process performance. Compared with ordinary hot-rolled steel plates, hot-rolled pickled plates remove the surface iron oxide scale, which improves the process performance of stainless steel plates and is conducive to electric welding, oiling and painting.
3. The specifications are high-precision. After leveling, the shape of the plate can be changed to a certain extent, thereby reducing the unevenness error.
4. Improved surface smoothness and improved appearance effect
