Cold Rolled Profile:
    Hot rolled coil as raw materials for cold rolling after pickling descaling, the finished product is rolling hard volumes, due to continuous cold work hardening caused by deformation of the strength of the rolling hard volumes, the increase in hardness, toughness plastic drop index Therefore stamping performance will deteriorate only for simple modification parts. Rolling hard volumes can be used as raw material for hot-dip galvanizing plant, because hot dip galvanizing line is provided with annealing line. Rolling hard volumes generally weighs 6 to 13.5 tons of steel coils at room temperature, the volume of hot pickling continuous rolling. An inner diameter610mm。
    Cold rolled steel, smooth surface, excellent processing for cars, refrigerators, washing machines and other home appliances, and industrial equipment, various construction materials. With economic development, cold-rolled steel sheet has been called modern society must be material.

Features:
    Because there is no annealing, high hardness (HRB greater than 90), machining performance is poor, only a simple directional bending less than 90 degrees (perpendicular to the winding direction) .
    Cold rolling at room temperature, is machined from hot-rolled plates made, although the process has since rolled steel sheet will heat up, was nevertheless called cold rolling. Due to continuous hot rolling after the cold variant made of cold-rolled, relatively poor mechanical properties, high hardness. It must be annealed to restore its mechanical properties without annealing called rolling hard volumes. Rolling hard volumes generally used to do without bending, stretching products.

Applications:
   Cold-rolled strip is widely used, such as automobile manufacturing, electrical products, rolling stock, aerospace, precision instruments, such as canned food. Cold rolled steel sheet is ordinary carbon steel cold rolled sheet for short, also known as cold-rolled plate, commonly known as cold plate, sometimes mistakenly written as cold rolling plate. Cold by ordinary carbon structural steel hot-rolled strip, after further cold rolling steel plate having a thickness of less than 4mm. Since rolling at room temperature, does not produce iron skin, therefore, a good cold plate surface quality, high dimensional accuracy, coupled with annealing treatment, the mechanical properties and process performance are superior to hot-rolled steel sheet, in many fields, especially in manufacturing of home appliances, has gradually use it to replace the hot-rolled steel sheet.
Product Usage:
    Cold plate has excellent plate type, surface quality and mechanical properties to meet user requirements. Widely used in galvanized substrates, household appliances, cooperage, automotive, construction, ceramic and other industries.
