Abstract (en)
[origin: EP1013351A2] The present invention provides a temper rolling method for temper rolling a steel plate for improving the brightness of the steel plate without requiring additional facilities and production steps. The method uses a steel plate containing 0.012 wt% or less of C and a temper rolling mill wherein at least the roll at the top front stand is a scratch bright roll having a surface roughness (Ra) of 1.2 mu m or less and at least the roll at the last stand is a bright roll having a surface roughness (Ra) of 0.5 mu m or less. <IMAGE>
