Title: Preventive method of solidification of sludge in pickling solution
Inventor: ISHIGURO TADASHI
IPC: C23G1/08
Filed: 1984-11-21
Abstract: PURPOSE:To form soft slurry or paste sludge and to remove easily the sludge in the stage of descaling a steel material by dispersing preliminarily pulverous particles to form seed crystals into a pickling soln. CONSTITUTION:The seed crystals are preliminarily added into the pickling soln. in a pickling cell prior to starting of pickling and thereafter said seed crystals are replenished thereto as necessary in the stage of descaling the steel material by using the pickling soln. contg. a hydrofluoric acid. The pulverous particles of >=1 kinds among oxide, activated carbon, plastic such as vinyl chloride and 'Teflon(R)', pickling sludge, oxide scale of the steel material, etc. are used as the seed crystals. Then the deposition of the sludge from the liquid phase arises preferentially on the seed crystals and the crystals grow approximately spherically. The slurry or paste sludge is therefore formed without depositing like rock sticking to the wall and the removal of the sludge is made easy.
