| 1. Brief description of the processing flow of Ribbed Steel Rebar in Coil | |
| (1) Raw material preparation First, select a suitable billet, usually a square billet, whose chemical composition needs to meet specific requirements, such as the content of elements such as C (carbon), Si (silicon), Mn (manganese), P (phosphorus), S (sulfur) and V (vanadium) needs to be within a certain range. (2) Heating The billet is heated to a specific temperature range, usually between 1040 and 1100°C, to ensure that the rolling temperature is between 990 and 1020°C. (3) Rolling After heating, the billet is first descaled by high-pressure water, and then rough rolling, intermediate rolling and pre-finishing rolling are carried out. These steps involve the use of multiple rolling mills, each with a specific hole design to gradually roll the billet into the required shape and size. (4) Water cooling After rolling, the steel needs to be water cooled to reduce the temperature and improve its performance. The temperature of the cooled steel needs to be controlled within a specific range, such as 860 to 900°C. (5) Finishing and forming After water cooling, the steel is finished rolled to obtain hot-rolled coil. Subsequently, the hot-rolled coil is cooled again and finally spun into coil. Chemical composition control Depending on the specifications of coil, the proportion of chemical composition will also vary. For example, the contents of C, Si, Mn, V and other elements in coils of φ6mm, φ8mm-φ10mm and φ12mm will be different2. Process optimization In order to ensure product quality and performance, the production process of coil needs to be continuously optimized. This includes the adjustment of process flow, process parameters and process formula to ensure that the product can meet the national standard requirements3. The above is a brief description of the coil processing process, covering the key steps from raw material preparation to final product forming. | |
| 2. Application | |
| It is widely used in bridges, tunnels, high-rise buildings, docks, house construction and other fields. Especially in places with high groundwater level, rainy and humid areas, the use of wire rod snail can improve rust resistance; in high-rise buildings, the use of wire rod snail can increase the stability of the structure. |
