4. Processing
.Processing is the processing of steel melt to get in shape and size. It also improve the properties of steel products. Variation diagram with the processing of hot and cold processing
.For steel sheet when through hot rolling and some can be used directly. But for the thin steel sheet is reduced in size by cold rolling. To obtain the desired thickness and other reasons as follows:
1.In order to improve the surface quality 2,
. To obtain desired mechanical properties 3,
. To obtain the thickness of the lower hot rolled steel 4,
. To control the error of the thickness of low
.Due to the hot rolling will save more than cold rolling. Therefore, in the production of thin steel sheet is started from hot rolling to the size of the one before. Then the cold rolling.
