Nov 09, 2013 · Continuous annealing process. Continuous annealing of cold rolled steel was first introduced by the Armco steel corporation in the year 1936 as a process step in the production of hot dip galvanized steel. Since then several improvements have been made in the process which allows several types of steels to be processed by this method.
Annealing of Cold Rolled Steel Steel WarehouseAnnealing of cold rolled steel involves a time and temperature controlled thermomechanical process used predominantly to make steel soft again after cold reduction.. Cold reduction or work hardening makes steel grain structure small and elongated.. This produces high strength, but low elongation. Annealing recrystallizes the grain structure restoring ductility so the material can adequately

Hot Rolled Black Steel (HR) LexWestOverview:Steel coils that have received no further treatment after being rolled to the desired thickness or gauge. ASTM A36 is the most commonly available of the hot-rolled steels. Process:Hot rolling is a process that is performed at an elevated temperature, which turns steel slabs into coils. Cold rolled and coated steel products are derived from hot rolled steel.
The steel is then allowed to cool slowly to room temperature in still air. This annealing process recrystallizes the steel for greater ductility, but because the steel is worked at room temperature, it maintains its strength. Working cold-rolled steel is much more difficult than working hot-rolled steel, so only basic shapes are possible.
