Inventor: OTAKE YASUHISA
IPC: C01G49/10
Filed: 1989-08-23
Abstract: PURPOSE:To regenerate a waste solution from etching treatment and to recover Ni by adding iron powder, iron block, and hydrochloric acid to a waste solution generated from the etching treatment of an Fe-Ni alloy sheet and composed principally of FeCl3, separating contained Ni by means of precipitation on the iron block, and then oxidizing FeCl2 in the waste solution into FeCl3 by means of chlorine gas blowing. CONSTITUTION:Since Ni is eluted in a waste solution which is used in photoetching of a shadow mask composed of Fe-Ni alloy sheet for color cathode-ray tube and is composed principally of FeCl3 and, as a result, etching velocity is decreased, the waste solution is heated by means of a heat exchanger 2 and put into a reaction vessel 4, where an iron powder 5, an iron block 5, and hydrochloric acid 7 are added to the waste solution and the resulting mixture is agitated. When FeC3 in the waste solution is reduced and the amount of FeCl2 is increased, an iron block 6b is further added and Ni in the waste solution is precipitated on the surface of the iron block 6b, and then, the iron block on which Ni is precipitated is separated from the waste solution by means of strainers 8. After water and hydrochloric acid are added to the waste solution in a dilution tank 9, a sludge 13 is filtered out by means of a filter press 12. The filtrate is introduced into a reaction vessel 14 and FeCl2 is oxidized into FeCl3 by means of chlorine gas blowing, by which the above filtrate is regenerated. On the other hand, the iron block on which Ni is precipitated is introduced into a hydrochloric acid cleaning tank 19 and hydrochloric acid 20 is added, by which Ni is dissolved in the form of NiCl and recovered from the iron block by separation.

Abstract: PROBLEM TO BE SOLVED: To obtain a method for drawing, reducing and sizing a seamless metallic tube by which defective bar stripping is not generated even when drawing, reducing and sizing are executed, by using a size capable of interstand tension imparting rolling. SOLUTION: It is detected with the detector 7 that the tip of a materiel 5 to be rolled is bitten into a 1st stand of the sizer 4. With a controller 8 receiving this detected signal, the number of revolutions of the roll of the preceding stage of a biting stand is successively reduced down to the number of revelations of roll at the time of deceleration based on the deceleration timing that is preliminary inputted according to the tip of the material 5 to be rolled is successively bitten into the stands after the 2nd stand. When the deceleration of the number of revolutions of roll of the sizer 4 is controlled like this, tension is not affected on the material 5 to be rolled in simultaneous rolling with a mandrel mill 3 and the sizer 4.  Consequently, it is eliminated for the material 5 to be rolled after rolling with the mandrel mill 3 to strongly stick to a mandrel bar 2 and detective bar stripping and thickness deviation in the length direction of the axis of tube are not generated.
