Cold rolled ribbed steel bar production line equipment process principle
The raw material is subjected to cold plastic deformation during rolling, which causes the grains inside the raw material to be distorted, broken, and elongated. Through online heat treatment temperature control, the distorted grains inside the raw material are recrystallized to form new, fine and uniform equiaxed grains, thereby improving the strength and toughness of the product.
Main process flow:
Dephosphorization machine to remove oxide scale-Dual active rolling-Online heat treatment-Flying shear to size-Fully automatic steel turning-Packaging and storage
Equipment composition
Descaling machine, dual-active rolling mill, online heat treatment device, flying shear, fully automatic steel turning machine, fully automatic material receiving device, etc. It can realize the production of high-ductility ribbed steel bars with a total of 9 specifications from 5.5mm to 12mm.
