What are the working principles and advantages of cold rolled ribbed steel bar machine?
The cold-rolled ribbed steel bar machine rolls ordinary low-carbon steel wire rods (such as Q195, Q235, etc.) into ribbed steel bars through the cold rolling process, significantly improving the strength and bonding properties of the steel bars. Its core process is to plastically deform the steel at room temperature, rather than the traditional hot rolling process.
Working principle
Raw material preparation: The wire rod is unrolled through the pay-off rack and enters the rolling mill.
Cold rolling forming: The rollers apply pressure to the steel, forming periodic ribs on the surface (such as crescent ribs).
Cooling and shaping: Lower the temperature through water cooling or air cooling to reduce internal stress.
Straightening and shearing: After adjusting the straightness of the steel bar, cut it according to the required length.
Finished product collection: Coil or stack into bundles.
Advantages and characteristics
High strength: cold working hardening effect improves tensile strength.
Material saving and cost reduction: ordinary low-carbon steel is used instead of high-carbon steel to reduce costs.
Good surface quality: uniform ribs and strong bonding with concrete.
Energy saving and environmental protection: no heating is required, reducing energy consumption and carbon emissions.
