Do you know the effect of the relative amount of pressure on the cold-rolled ribbed bars in the process of using the cold-rolled mill or cold-rolled ribbed bars production line? Now, I would like to explain this question to you:
In general, the tensile strength of cold-rolled ribbed bars increases with the increase of the pressure drop, and the change is steeper when 0-10%, but flattens out when the range is above 10%. And the elongation decreases with the increase of the relative pressure down. When the relative pressure down is in the range of 0-10%, the elongation changes obviously, but becomes stable in the range of above 30%.
