Detail

Rolling hard coil: continuous rolling of hot-rolled pickling coil at normal temperature.


Features: because it has not been annealed, its hardness is very high (HRB is greater than 90), and its machining performance is very poor, so it can only carry out simple bending processing with directivity less than 90 degrees (perpendicular to coiling direction). Some steel plants can provide four fold edge treatment.



Product application


(1) After annealing, it is processed into common cold rolling; coating;


(2) The galvanizing unit with annealing pretreatment device processes galvanizing;


(3) Panel that basically does not need to be machined.
