HOT ROLLED PICKLING PLATE

Hot Rolled Pickling plate: 

(Pickling plate, pickled steel board) is made of high-quality hot-rolled sheet as raw material. After pickling unit to remove oxide layer, trimming, finishing, surface quality and use requirements (mainly cold-formed or stamping performance) The intermediate product between hot-rolled sheet and cold-rolled sheet is an ideal substitute for some hot-rolled sheet and cold-rolled sheet.

Compared with hot-rolled sheet, the main advantages of pickling sheet are:

1. Good surface quality, because hot-rolled pickling sheet removes the surface iron oxide scale, improves the surface quality of steel, and is convenient for welding, oiling and painting.

2. The dimensional accuracy is high. After flattening, the plate shape can be changed to a certain extent, thereby reducing the deviation of unevenness.

3. Improve the surface finish and enhance the appearance effect.

4. It can reduce the environmental pollution caused by users' dispersed pickling. Compared with cold-rolled sheet, the advantage of pickling sheet is that it can effectively reduce the purchase cost of users under the premise of ensuring the surface quality and use requirements. Many enterprises put forward higher and higher requirements for high performance and low cost of steel.

With the continuous advancement of steel rolling technology, the performance of hot-rolled sheet is approaching that of cold-rolled sheet, so that "replacing cooling with heat" can be technically realized. It can be said that pickling sheet is a product with a relatively high performance-price ratio between cold-rolled sheet and hot-rolled sheet, and has a good market development prospect.

The production of professional pickling boards began in September 2001 when the pickling production line of Baosteel was put into operation.

Product introduction:

The pickling plate market mainly reflects the following four aspects: alternative cold rolling, alternative hot rolling, alternative import and alternative small pickling. Among them, substitute imports and small pickling are actually existing markets, and the market is limited and cannot be completely replaced. With the rapid development of automobile, machinery, light industry and other industries, enterprises are facing the huge pressure brought by this market competition, and the requirements for product cost and product quality are increasing day by day. Plate and hot plate, will gradually be recognized by users.

The main processes of hot-rolled pickled sheet include laser welding, position extension straightening, turbulent pickling, on-line leveling, trimming, on-line oiling, etc.

Baosteel's pickling specifications are generally 1.0-6.1*800-1650mm. Products include low, medium and high strength grades of stamping steel, automotive structural steel, etc., which are mainly delivered in the form of steel coils. Technological characteristics After the iron oxide scale on the hot-rolled steel plate is removed with hydrochloric acid, a beautiful and smooth surface is obtained. 

Features:

1. Cost reduction, replacing cold-rolled sheets with pickled sheets can save costs for enterprises.

2. The surface quality is good. Compared with the ordinary hot-rolled sheet, the hot-rolled pickling sheet removes the surface iron oxide scale, improves the surface quality of the steel, and is convenient for welding, oiling and painting.

3. High dimensional accuracy, after flattening, the plate shape can be changed to a certain extent, thereby reducing the deviation of unevenness.

4. Improve the surface finish and enhance the appearance effect.

Applications:

The main uses of hot-rolled pickling in the automotive industry are as follows: automotive chassis systems, including girder, sub-beam, etc. Wheels, including rims, spokes, etc. Cab interior panel. The carriage plate is mainly the floor of the carriage of various trucks. Other stamping parts, including bumpers, brake sleeves and other small parts inside the car.
