Process for continuously annealing aluminum strip
Abstract
Abstract THE ANNEALING OF STRIPS OF ALUMINUM AND ALLOYS OF ALUMINUM IN THE COLD ROLLED STATE IN WHICH THE STRIP IS CONTINUOUSLY ADVANCED FOR SEQUENTIAL INCREASE IN TEMPERATURE SUBSTANTIALLY UNIFORMLY CROSSWISE OF THE STRIP BY SUCCESSIVELY PASSING THE STRIP BEFORE A FIRST SERIES OF HEATING ELEMENTS WHICH INTRODUCE ONE INCREMENT OF HEAT, OVER A PORTION OF A HEATED DRUM WHICH INTRODUCES AN ADDITIONAL INCREMENT OF HEAT, BEFORE A SECOND SERIES OF HEATING ELEMENTS WHICH INTRODUCE A STILL FURTHER INCREMENT OF HEAT, AND THEN OVER A PORTION OF A HEATED DRUM FURTHER TO RAISE THE TEMPERATURE OF THE STRIP AND FINALLY OVER COOLING ROLLS TO REDUCE THE TEMPERATURE OF THE STRIP AND SUPPORTING THE STRIP ON ROLLERS BETWEEN THE COOLING MEANS AND THE WIND-UP ROLL TO EFFECT THE DESIRED GRIPPING RELATIONSHIP FOR FEEDING THE STRIP TO THE WIND-UP ROLL.
