Scanning Electronic Microscope(SEM)and EDAX were used to analyze the surface defect of mandril for hotrollingsteeltube. Appearance and growth of the surface defect were investigated and discussed.
The master production scheduling(MPS) problem of hotrolling seamless steeltube is formulated as a mixed integer linear programming model.
