Definitions

  • the invention relates to a method for continuously manufacturing cold-rolled steel, more particularly to a method for continuously manufacturing cold-rolled steel from white steel.
  • a conventional process for making stainless steel essentially includes casting, hot rolling, and cold rolling.
  • a steel slab obtained from casting is hot rolled to obtain a black steel coil, which is then annealed and pickled to obtain a white steel coil.
  • the white steel coil can be further processed by cold rolling, annealing, pickling, temper rolling, tension leveling, etc., to obtain a steel coil product.
  • the product obtained by cold rolling, annealing, and pickling is known as a 2D steel coil
  • the product obtained by further temper rolling and tension leveling the 2D steel coil is known as a 2B steel coil.
  • a conventional process for manufacturing cold-rolled steel is conducted using a multi-stage production line including a steel coil preparation installation 11, a cold rolling installation 12, an annealing-pickling installation 13, a temper rolling installation 14, and a tension leveling installation 15, which are separate from one another.
  • the steel coil preparation installation 11 is used for uncoiling a white steel coil 100 into a white steel strip 400, which is welded with guide portions each having a length of 8-10 meters at two ends thereof and is then coiled into a steel coil 200.
  • the steel coil 200 is transported to the cold rolling installation 12.
  • the steel coil 200 is uncoiled into a steel strip 400, which passes through the cold rolling installation 12.
  • the cold rolling installation 12 is a 20-high cold rolling mill, and is used for cold rolling the steel strip 400 to have a predetermined thickness.
  • the steel strip 400 after cold rolling is coiled into a steel coil 200, which is transported to the annealing-pickling installation 13.
  • the steel coil 200 is uncoiled into a steel strip 400, which passes through the annealing-pickling installation 13, in which the steel strip 400 is annealed, and is then pickled to remove scale from the steel strip 400.
  • the steel strip 400 after pickling is coiled into a steel coil 200, which is the 2D steel coil.
  • the 2D steel coil 200 can be further transported to the temper rolling installation 14.
  • the steel coil 200 is uncoiled into a steel strip 400, which passes through the temper rolling installation 14.
  • the temper rolling installation 14 is used for imposing gloss on the steel strip 400.
  • the steel strip 400 after temper' rolling is coiled into a steel coil 200, which is transported to the tension leveling installation 15.
  • the steel coil 200 is uncoiled into a steel strip 400, which passes through the tension leveling installation 15, in which the steel strip 400 is tension leveled, and is then trimmed and coiled to obtain a steel coil product 300 (i.e., the 2B steel coil).
  • U.S. Patent No. 6,478,899 discloses a method and an installation for making a cold-rolled stainless steel strip, and consists of continuously executing on a single production line all the process steps for fabricating a cold-rolled stainless strip from a thin strip cast directly from liquid metal, i.e., from the casting step through finishing steps to packaging the strip in the form of a coil.
  • the method and installation disclosed therein start from casting a stainless steel strip directly from liquid metal, the operating units and steps involved are relatively complicated. Therefore, the technique disclosed therein is impractical for use in the industry.
  • U.S. Patent No. 6,546,771 discloses a method for manufacturing strips of stainless steel, which comprises rolling in cold condition of strips which in a foregoing process have been manufactured through strip casting and/or have been hot rolled. According to various specific wants of the final product, the stainless steel shall pass once or twice through a rolling mill line. Additionally, the rolling mill line or parts of it also can be used for processes which are aimed at manufacturing strips with various specific features that are of significant importance for some applications. Since parts of the rolling mill line should be stopped in view of the specific requirements for the final product, the utilization rate of the rolling mill line is relatively low.
  • the object of the present invention is to provide a method for continuously manufacturing cold-rolled steel to overcome the aforementioned shortcomings of the prior art.
  • the method for continuously manufacturing cold-rolled steel of this invention includes the steps of:
  • the preferred embodiment of a method for continuously manufacturing cold-rolled steel according to this invention includes the steps of:
