Some Hot-Rolled Steel Knowledge...
Strip is to suit the different needs of the industrial sector produced a long narrow plate. Also known as the strip strip, the width of less than 300 mm in general, but with economic development, the width has no limit. Vol Strip into supply, a high dimensional accuracy and surface quality, and ease of processing, material savings and other advantages. Same with steel, strip steel material used by ordinary strip divided into two types and quality strip; According to the method of processing heat, cold-rolled two.
      Widely used in the production of welded steel pipes for the cold rolled steel strip billets, manufacture bicycle frame, wheels, the closure device, washers, springs films, saw-blade and blade, and so on.
