Abstract

The results of modeling the processes of annealing cold-worked coils of extra-thin steel strip of high quality
 in protective atmospheres of hydrogen and nitrogen in bell-type furnaces are presented. An algorithm for calculating
 the optimal value of the heating time is given, taking into account the thermophysical properties of both processed
 hard-worked coils of extra-thin steel strip and protective atmosphere gases. A technique for optimizing the modes
 of annealing of hard-worked coils of extra-thin steel strip in a bell-type furnace in a pure nitrogen environment relative
 to the basic mode in a pure hydrogen environment is presented.
