摘要

In the reducing operation of zircaloy tubes, lubricants are applied on both inner and outer surfaces, which must be cleaned before vacuum annealing of the tubes. Degreasing is a vital unit operation in production of zircaloy tubes, which are used as cladding of fuels for nuclear power plants. The rate limiting operation of the multistage degreasing of zircaloy tubes is the treatment with hot alkali solution. Different lubricating oils have been used in the tube reducing mill. A detailed study was felt necessary, since it is the rate determining step in the degreasing operation. In this operation five different chemicals are used sequentially for saponification, chelation, emulsification, deflocculating and wetting. Selection of proper physico-chemical parameters may reduce the soaking time. The effect of the concentration of different chemicals and process parameters on the cleansing action was studied with an objective to find a cost effective optimum composition for degreasing operation. The detailed process of degreasing, parametric study, results, optimization of process parameters and conclusions are discussed in this paper.
