Production Process and Feature

· 1, To eliminate work hardening, to acquire the construction that is satisfactory. After the use of different functionality conditions, the microstructure of the bright annealed after the request is different heat treatment process is different.


· 2, Since the item surface heats below a protective. Access to non-oxide glowing, good corrosion resistance of the surface. Together with the surface obtained from ordinary annealing and pickling, the The oxidation process, and the resistance is better than that of Furnace, in particular, purity, residual oxygen and dew point. Compared · the 2B plate after polishing.

Air of a mixture of hydrogen and nitrogenand Chromium-depleted surface of the strip is reduced as a result of lack of Surface is obtained by controlling the atmosphere


· 3, The bright processing Maintain the finish of the rolling surface, no longer be processed to get a surface. Because of the bright requirements. And has been accessed to the mirror surface, it Can to be used with no other machining The coil or sheet surface keeps its luster


· 4, The pattern, you can easily design coil or special cold-rolled strip. Create a special rolling pattern surface strip or coil. As the annealing Process, Can There's no change in the surface of steel, the surface can be completely retained


· 5, There is no pollution brought on by ordinary pickling technique. After Annealing the strip does not demand therapy, Problems caused by pickling. Use a variety of chemical substances such as acids, there are no contamination


· 6, To achieve the control of the stainless steel coil straightness. Because the design of the bright annealing furnace allows sub-section adjustment along the width of the strip or coil, the on-line control of the sheet can be realized by adjusting the cooling rate in the width direction of the strip by the air flow diversion.
