Abstract

PURPOSE:In heating strips, etc. in contrinuous annealing furnaces, to control the in-furnace temperature to the required strip heating temperature by eliminating the temperature variations of the strips near the joint of the strips produced in the annealing furnace owing to the change of strip thickness, etc.
