The annealing process involves heating the steel, which is passed continuously through the furnace, to certain temperatures and then cooling it, resulting in a change in the crystalline structure of the steel. If the carbon in the steel is more than 0.003%, then the steel needs to be decarburized. FRead more

the carbon in the steel is more than 0.003%, then the steel needs to be decarburized. For this, the strip of
steel sheet is continuously fed into the furnace at the decarburization end and after the de-carburization;
the strip enters the annealing zone, where stress relief and grain growth takes place. The decarburization
process is very important since it reduces the carbon percentage in strips which determines the quality and
grade of the end product.
