Cold rolling technology originated in Germany in the mid-19th century and was initially used to produce cold-rolled strip steel with a width of 20 – 25 mm. So, what is cold rolled steel? The following will introduce cold rolled steel in detail from aspects such as its definition, production process, performance characteristics, and application fields:<\/p>\n

\ud53c\ud074:<\/strong> A continuous pickling unit is used to remove the surface iron oxide scale from the hot-rolled coil. In the past, sulfuric acid was used as the pickling solution, but now hydrochloric acid is more commonly used. Before pickling, the coils are first welded and coiled, and some are also subjected to continuous “black annealing”. After pickling, the coils are cleaned, dried, and trimmed and coiled.<\/p>\n
