Title: Rolled material surface treatment appts. -  has jets on both sides of workpiece below fluid wheel in vessel at an acute angle to the material surface
Inventor: RITUPER RAFAEL DR
IPC: C23G3/02
Filed: 1990-10-04
Abstract: To apply a chemical or electrochemical surface treatment process to strip material, such as rolled material, the material is immersed longitudinally in an acid or lye or base. The treatment fluid is forced from both of the long sides of the material from above and below it against each other, and at an acute angle to the material surface, below the fluid level in the treatment vessel. - The treatment fluid is pref. forced against the material surface at an angle of 5-30 deg. or 15-20 deg., to travel at a speed equal to or more than 2.0 m/sec. against the material surface. The treatment vessel has a longitudinal shape, matching the outline of the material being processed, and is covered with a lid. The vessel is filled with a treatment fluid to a level to cover the material being processed, and the assembly has at least one recirculating pump. The spray jets (12), facing each other across the material, are aligned at an angle of 5-30 deg. or 15-20 deg. The jet (12) angle can be adjusted and they extend generally over the whole length of the treatment vessel (1). The jets (12) are at a small gap from each other on flow tubes (8-11), above each other with a gap between, on both sides of the workpiece in the vessel (1).
