摘要： The invention refers to a process for production of raw stainless steel castings, in particular for stainless steel strip, covering rolling and annealing of cast material if required, as well as de-scaling, in particular by pickling in aqueous media, and coiling for raw stainless steel strip if necessary. In order to achieve greater flexibility as regards steel grades that can be treated and dimensions of the castings, the material is to be heat-treated in batches and preferably also annealed, cooled and de-scaled immediately after the final heat treatment stage, without intermediate storage, in batches. In a process covering the process stages for casting, rolling of the cast material if necessary, cooling, as well as de-scaling, in particular by pickling in aqueous media, and coiling, if necessary, to form raw stainless steel coils, the material is to be cast in batches and de-scaled immediately afterwards without intermediate storage in order to obtain the same advantage. The invention also covers equipment to carry out the process described.

摘要： A process and apparatus for pickling the surface of stainless steel strip feeds the stainless steel strip through a plurality of pickling tanks containing a hydrochloric acid pickling acid. The pickling acid bath is maintained at a temperature of at least about 40° C. An oxidizing agent is added to the acid solution in an amount to maintain at least about one third and preferably at least about half of the soluble iron in the form of ferric chloride based on the total amount of iron in the acid solution.

摘要： A process for regeneration of electrolytes, in particular Na2SO4, from waste pickles created during picking of stainless steel, in particular stainless steel strips. The electrolytes are regenerated by adding NaxHySzOv in an acid solution whereby Cr6+ is reduced to Cr3+. Variables x, y, z and v having the following values: x=0 to 2, y=0 to 2, z=1 to 6, v=2 to 6.
摘要翻译：从不锈钢采摘期间，特别是不锈钢带采摘时产生的电解质，尤其是Na 2 SO 4再生的方法。通过在酸溶液中加入NaxHySzOv再生电解质，由此Cr 6+还原成Cr 3+。具有以下值的变量x，y，z和v：x = 0至2，y = 0至2，z = 1至6，v = 2至6。
