Open fire furnace / Annealing Pickling from JJRS
Continuous annealing
Annealing is a process in which metals, glass and other materials are treated to render them less brittle and more workable. Continuous steel annealing subjects rolled strip product to a sequence of furnaces to elevate and profile the strip temperature according to grade and dimension. The end result is an increased ductility and removal of strains that lead to failures in service. Because the overall length of strip in the furnace system is a few kilometers long, the furnaces are vertical, with the strip making several traverses within each furnace.
Continuous annealing lines have the following features:
Accumulators
Variety of furnaces
Atmosphere control
Line stop
Furnaces are necessary to give steel the desired properties by heating to particular temperatures and profiles thereby determining the grain structure within the metal, and to prepare for further processing such as galvanizing.
In the heating furnace, the cold strip is heated to the highest temperature of the annealing profile. Because of the danger of oxygen contamination and flame length hotspots, the heat is radiated to the strip using ceramic radiant tubes, themselves fired by gas.
The soaking furnace is required to maintain strip temperature and is electrically heated.
