Precision steel strip with thin plate thickness, narrow width and long length. Its width is generally between 20mm—200 mm. Supplied in rolls, and its specifications are shown as thickness x width. It is divided into good and ordinary steel strip according to the quality of steel. And it is divided into hot rolled steel strip and cold rolled steel strip according to the rolling method.Steel strip can be widely used in manufacturing of Welded pipes, clamps, washers, spring blades, saw blades, blades, etc. Next, I will introduce to you the method of improving the surface of precision steel strip.
The chemical reaction method is used to process the metal surface in the precision steel strip. Under the cold-rolled status, the strong reaction of the steel strip tends to produce small band-shaped bubbles, while the pickling bubbles tend to appear on the residual surface, so the product will not have a smooth surface. Cold rolled strip is usually called cold rolled steel strip. In short, the production of cold-rolled narrow steel strip has the feature of simplicity, flexibility, low investment and high efficiency. Cold rolled steel strip manufacturers will learn more with you!
Pickling bubbles are caused by hydrogen produced in the interaction of acid and bare metal. Cracking noise will appear during cold rolling progress. Its feature of appearance is small strips of bubbles and black fine cracks after cracking.
After the hot rolled coil is transported to the coil car via the entrance walking beam, the coil diameter and width are measured by the coil detection device, and the coil is automatically centered. Then, the coil car will transport the coil to the position of the decoiler, and the decoiler will uncoil the coil. The anti-wrinkle roller will be put in at the same time to prevent the waist from being folded when the strip is uncoiling, and then straighten it by the straightening machine. In order to ensure that the strip passes through the unit smoothly, and then enters the welding machine for head and tail welding, so that the strip can run continuously on the production line.
After uncoiling, the decoiler enters the levelling machine for straightening to ensure that the strip enters the unit smoothly. The straightening tank reacts with the acid solution in the pickling tank to remove the oxide scale on the surface of the strip, and then enters the cleaning tank.
The device can only clean the residual scale on the surface of the steel plate and the steel belt through the reaction of the pickling liquid. In order to improve the shape of the steel plate, steel plate processing has been extensively developing. The main purpose of rolling is to make the steel plate reach a predetermined thickness and shape. At the same time ensure the flatness of the steel plate. In the process of flattening after rolling, the steel plate should meet the requirements of flatness in use to improve the performance of the steel plate and the quality of the coating. In the process of production, when uncoiled strip steel is found to be bent, it can be welded to ensure its smooth operation.
Above content is about the methods to improve the surface of precision steel strip.Precision steel strip must be processed with good quality materials in terms of quality and equipment.Unlike cold-rolled plates, precision steel strip is not made by cold rolling technology, not even changing the rolling material. The configuration of equipment, technology, personnel, and management are special. The real high-precision stainless steel strip production is a high-precision, high-tech engineering system .
