Reasons For Unqualified Quality Of Cold Rolled Ribbed Steel Bars


In the actual process of producing cold rolled steel bars, many manufacturers of cold-rolled ribbed steel bars inevitably have unqualified quality of cold rolled ribbed steel bars. According to the technical staff of Gongyi Jindi Metallurgical Equipment Co., Ltd, the unqualified quality of cold rolled ribbed steel bars has the following three situation: the height of the ribbed steel bars is not high enough, the longitudinal ribs are high and thick, and the upper and lower patterns are misaligned. Below, Jindi Metallurgical Equipment will analyse the reason for the unqualified quality of ribbed steel bars.

       

1, The height of the transverse rib is not enough

According to the analysis of Jindi Metallurgical Equipment, the hard raw material, the large distance between the two rollers, and the roller wear is extremely easy to cause the transverse rib height of the cold rolled ribbed steel bar not enough. The solution is to change the smaller hardness of raw material, adjust the spacing between the two rollers, and change the rollers.

       

2, The longitudinal ribs are too high and too thick

The reason why the longitudinal ribs of the cold rolled ribbed steel bars are too high and too thick is consistent with the reason why the height of the transverse ribs is insufficient, and the customer can eliminate them according to the solution mentioned above.

       

3, The upper and lower patterns are misaligned

The reason why the cold rolled ribbed steel bars have misalignment of the upper and lower patterns is caused by the misalignment of the upper and lower grooves of the cold steel rebar machine. Therefore, if this situation is to be resolved, the manufacturer can adjust cold steel rebar machine positioning bolt and presses the roller lock nut to solve the problem.

       

The reasons for the unqualified quality of cold rolled ribbed steel bars are the above three.The machinery and equipment produced by Gongyi Jindi Metallurgical Equipment Co., Ltd include: cold rolling mill, steel cold rolling machine,rebar cold rolling mill, cold rolled ribbed steel bar machine, steel rebar rolling mill and cold rolled steel mill, cold rolled ribbed steel bar production line, wire-receiving machine, steel bar Straightening cutting machine, steel straightening machine, steel cutting machine, flying shear cutting machine, steel bar stretching machine, high-frequency heat treatment equipment, steel straightening and cutting machine, I-shaped wheel take-up machine, steel filp rack, etc.For more details, please visit www.jindimachine.com or call: 0371-64388822,13674996266 to consult with us!
