Application of cationic emulsion in stainless steel cold rolling

Emulsion,obtained by cationic emulsifiers,allows much larger oil droplets with narrower particle distribution,slows down the contamination from iron fines to the oil droplets,and is further enhanced with higher boundary and elastohydrodynamic lubrication for a relatively slower rolling process but high rolling force.As a result,it is suitable for the cold rolling of stainless steel.Cationic emulsion is now applied in a 1 750 mm 5-stand tandem cold rolling mill of Baosteel to roll stainless steel and carbon steel.The production process is stable and the product quality satisfies customer requirements.
