a few days ago, 2 heavy successes completed southwest aluminium course of study (group) finite liability company 4300 clement of roller of the job in group of board heat rolling mill quench the job. NT#mm9R
Southwest aluminium 4300 clement the working roller in group of board heat rolling mill because demand of roller body hardness is extremely high (Hs70~75) , need to undertake to its roller body temper by dipping in water is handled expressing alone, the length of Dan Jigun body and roller body diameter exceeded the processing capacity of equipment again. For this, 2 refashion revised practical processing plan, used what all had used without manufacturer inside countrywide limits to quench craft, technical personnel controls material composition strictly to reach quench heat preservation time, cooling rate, ensured the performance characteristics of working roller and quality.
