Inventor: STARCEVIC JOVAN
IPC: C25F1/06
Filed: 1999-12-20
Abstract: PURPOSE: A chemical or electrochemical pickling method of stainless steel is provided to pickle stainless steel in an acid solution without containing nitric acid. CONSTITUTION: An acid pickling solution is neutralized by using soda(NaOH) or sodium carbonate(Na2CO3). A metal hydroxide is filtered and recovered by using microfiltration preferably. Herein, sodium sulfate is generated. The sodium sulfate(Na2SO4) is recirculated by using neutral electrolyte. The acid pickling solution is neutralized and neutral electrolyte is regenerated thus cost is remarkably reduced. The used electrolyte is obtained from one or more cool rolling strip pickling lines and added to acid pickling solution without containing nitric acid from one or more hot rolling strip pickling lines. Thereby, a transformation method the most advantageous in the cost for investment and operation according to a stainless steel plant is selected.
