Introduction of Hot-Rolled Steel Strip for Shenzhen Baogang Direct Seam Welding Sleeve
Shenzhen Baogang Direct Seam Welding Sleeve is a sleeve for direct seam welding of pipeline. It is made of hot rolled steel strip produced by Shenzhen Baogang. The hot rolled steel strip is a steel product produced through hot rolling process. It has a various of shape and size and wide application range.
Manufacturing Characteristics of Hot-Rolled Steel Strip
The hot rolled steel strip is composed of a slab and a single coil. The slab is heated in a reheating furnace at high temperature and rolled band in the horizontal and vertical direction. After rolling, the hot rolled steel strip has high yield strength, high ductility, uniform material, good surface quality and is easier to process. The process of making hot rolled steel strip is simple and the cost is lower than other steel processes.
Production Process of Hot-Rolled Steel Strip
The production process of hot-rolled steel strip usually includes 4 steps: slab re-heating, rolling, cooling and finishing. The first step of the production process is the slab re-heating. The slab is heated in a reheating furnace and then rolled by a rolling mill. The rolling mill can roll the steel strip to the required thickness and width. The third step is cooling. After rolling, the hot-rolled steel strip needs to be cooled to reduce the temperature and make sure the material has enough strength. During the cooling process, the roller straightening and flattening machine will straighten the steel strip and make it even. The last step is the finishing. This includes trimming the edges and removing any residues.
Quality Control of Hot-Rolled Steel Strip
Before the hot-rolled steel strip is used in producing the Shenzhen Baogang Direct Seam Welding Sleeve, the manufacturers need to do quality control to make sure the product meets the standards. The quality control process includes visual inspection, chemical analysis, dimensional measurement and mechanical testing. The visual inspection is to check the surface of the steel strip for any defects or any irregularity. The chemical analysis is to make sure the steel strip meets the chemical composition requirements. The dimensional measurements are to make sure the steel strip meets the size requirements. The mechanical tests are to make sure the steel strip has the required strength and toughness.
Conclusion
Hot-rolled steel strips have good yield strength, high ductility and good surface quality, which make them suitable for producing the Shenzhen Baogang Direct Seam Welding Sleeve. The production process of hot-rolled steel strips involves four steps. The quality control process is to ensure that the product meets the necessary standards before it is used in producing the welding sleeve.
