Performance Characteristics of Twisted Steel Bar
High strength: The twisted steel bar is processed in multiple passes, including high temperature pressing and cold working. This gives it a high strength. Its category is divided into HRB335, HRB400, HRB500 grades, the higher the grade, the greater the strength.
Excellent compression capacity: Due to its special production process and material composition, its compression capacity is about 50% higher than ordinary steel bars. This makes it more stable and reliable under pressure.
Good fastness and resistance: in the production process, this steel bar will add a certain amount of “vanadium” element. This element significantly increases its resistance, making it more stable when impacted by external forces.
Excellent seismic performance: seismic rebar in various indicators are higher than ordinary rebar. It can effectively resist external forces and ensure the stability of the structure when the building is deformed or tilted.
Enhance the binding force of concrete: the spiral grain on the surface of the steel bar can increase the friction force with the concrete, so that the concrete and the steel bar are better combined into one. This improves the strength and durability of the overall structure.
The Production Process of Twisted Steel Bar
Raw material preparation: Carbon steel rods are used as raw materials for cleaning, cutting and tempering. Ensure that the raw material has a certain toughness and strength.
Cold drawing process: the cut steel is cold-drawn in multiple passes to process into steel bars of specified diameter and length.
Pre-treatment: including cleaning and pickling, remove dust and dirt on the surface of the steel bar, and make its surface smooth and clean.
Thread machining: After grinding and adjusting the diameter of the rebar, heat treatment is performed. The worker then forms the spiral pattern by rolling the thread processing machine.
Post-treatment: including quenching treatment to improve the hardness and tensile strength of the steel bar. Then wash, paint and other processing. Finally, fixed length cutting, labeling and inspection are carried out to ensure that the finished product meets the quality standards.
Factory inspection: The finished steel bar needs to go through a strict inspection procedure. The factory ensures that the indicators meet the standard requirements before leaving the factory for sale.
Application Prospect
With the continuous development of global economy and the acceleration of urbanization process, the application prospect of twisted steel bar is very broad.
Market demand continues to grow: The economic growth and infrastructure construction needs of emerging market countries are increasing. This provides a huge market space for the steel industry.
Application areas are expanding: In addition to the traditional construction and infrastructure construction fields, it is also widely used in new energy, environmental protection, agriculture and other fields. For example, in the field of wind power as an important material for wind turbine towers. In the field of environmental protection, it is used in the construction of sewage treatment plants and other facilities. In the agricultural field, it is used in the construction of breeding greenhouses and other facilities.
Technological progress promotes the development of the industry: With the continuous progress of science and technology and the continuous improvement of production technology, the production efficiency and product quality of the factory have been greatly improved. At the same time, the research and development and application of new materials have also injected new vitality into the development of the industry.
