摘要： A metal stripping system and an operation process therefor which includes the following elements and steps. A main part of this system is a crystallization apparatus for metal stripping comprising a mixing zone of organic solvent and fluoride series stripping solution, a settling zone for organic solvent, a settling zone for stripping solution, a separation zone for fluorinated metal complex crystal and a stripping solution cooling zone. In the operation of the system wherein the organic solvent containing extracted metal ions is contacted with the fluoride series stripping solution to deposit the fluorinated metal complex crystal and then the crystal is recovered as metal or metal oxide, the stripping solution is circularly used by supplying NH.sub.4 HF.sub.2 solution to the cooling zone, supplying the stripping solution discharged from the apparatus and absorbed with a decomposition gas of the crystal to the mixing zone, and supplying a filtrate after the crystal separation to the settling zone for stripping solution.

摘要： A method and an apparatus for rolling metal strips by a tandem cold rolling mill. The strip is periodically swung in its width directions at a location upstream of the tandem rolling mill, to bring the strip into contact with rolls of the tandem cold rolling mill over areas of the rolls as widely as possible, thereby preventing irregular wears of the rolls to make it possible to produce defect-free metal strips.

摘要： Hot-rolled low-carbon steel strip with an excellent press-workability capable of forming a smooth pressed surface consisting essentially of up to 0.12 wt. % carbon, up to 0.01 wt. % nitrogen, up to 0.0094 wt. % boron, and other specific optional ingredients, the B(%)/N(%) ratio being 0.3 to 0.94. The micrograin size number, JIS, of ferrite in the steel strip as hot-rolled is 7 to 9. The steel strip is made by hot-rolling while controlling the temperatures at the entry and delivery ends of a hot-strip finishing mill.
