Manufacturing Process Of Duplex S31803 Plates
Reheating Furnace
Reheating furnaces are used in hot rolling mills to heat the steel stock to the rolling temperatures.
Scale Breaker
Slab moves first through a scale breaker, which is a two-high rolling mill with vertical rolls that loosens the furnace scale and removes it with high-pressure water jets.
Finish Rolling
The last stage of the rolling process is cold rolling,
Cooling
Cooling or Quenching is a process of cooling a metal at a rapid rate.
Skin Pass Mill
This produces high-gloss surfaces and achieves the desired mechanical strip properties such as deep-drawing strength.
Marking & Packing
Proper packaging and labeling not only makes the final product look attractive but also save a huge amount of money by saving the product from wrong handling.
