<p>A method of removing the oxide scale on the surface of hot-rolled stainless steel, especially hot-rolled wire which has passed through a controlled, forced cooling directly after the final roll pair of the rolling mill. The hot-rolled, directly-cooled wire is treated for a period of about 1-120 minutes in a solution of dilute sulphuric acid with a concentration of 25-1200 g sulphuric acid per liter pickling solution. The temperature of the solution is kept at 40-100 DEG C during the course of the treatment.</p> |
