Definition and Composition

Cold rolled strip is a steel product produced through the cold rolling process. Specifically, cold-rolled strip steel is a steel product obtained by rolling hot-rolled strip steel or cast strip steel through a cold rolling mill at normal temperature, that is, below the recrystallization temperature. Its thickness is usually between 0.1-3 mm, and its width is in the range of 600-2000 mm. Cold-rolled strip steel has high dimensional accuracy, good surface quality and excellent mechanical properties.

Classification

Classification by material:

Carbon structural steel cold-rolled strip: mainly used in building structures, machinery manufacturing and other fields.

Stainless steel cold-rolled strip: It has high corrosion resistance, heat resistance and strength, and is often used in chemical equipment, food processing equipment and other fields.

Special alloy cold-rolled strip steel: such as titanium alloy, nickel alloy, etc., has special physical and chemical properties and is used in aerospace, nuclear industry and other fields.

Classified by width:

Narrow strip steel: with a width between 100 and 600 mm, it is often used to manufacture small parts, pipes, etc.

Medium wide-band steel: with a width between 600 and 1000mm, it is commonly used in automobile manufacturing, machinery manufacturing and other fields.

Wide steel strip: with a width above 1000mm, it is commonly used in large building structures, ship manufacturing and other fields.

Classified by thickness:

Ultra-thin strip or foil: less than 0.2mm thick, commonly used in electronics, communications and other fields.

Thin strip steel: thickness is between 0.2~1mm, commonly used in automobile manufacturing, home appliance manufacturing and other fields.

Medium-thick steel strip: with a thickness between 1 and 3 mm, it is commonly used in machinery manufacturing, building structures and other fields.

Product Advantages

1.Accurate dimensions: Cold-rolled steel strip products have precise dimensions and uniform thickness. The thickness difference of the strips generally does not exceed 0.01~0.03mm or less, which fully meets the requirements of high-precision tolerances.

2.Thin thickness: Through the cold rolling process, extremely thin strips that cannot be obtained by hot rolling can be produced, and the thinnest strip can be less than 0.001mm.

3.Good surface quality: The surface quality of cold-rolled strip is superior, and there are no defects such as pitting and pressed-in oxide scale that often occur in hot-rolled strip. Moreover, strip steel with different surface roughness (glossy surface or rough surface, etc.) can be produced according to the user's requirements to facilitate processing in the next process.

4.Good mechanical properties and process properties: Cold-rolled strip steel has high strength and low yield limit, as well as good mechanical properties and process properties such as deep drawing performance.

5.High productivity: Cold rolling production can achieve high-speed rolling and full continuous rolling, with high productivity.

Product Application

1.Building structure: Cold-rolled strip steel is often used in beams, columns, beams, floors and other components in building structures. Its excellent strength and stability properties can improve the stability and load-bearing capacity of building structures and ensure the safety of buildings.

2.Automobile manufacturing: Cold-rolled strip steel is widely used in automobile manufacturing, including body parts, wheels, axles, etc. Cold-rolled strip steel has excellent formability and welding properties, and can meet the requirements for material strength and wear resistance in automobile manufacturing.

3.Machinery manufacturing: Cold-rolled strip steel is often used to manufacture parts of machinery and equipment, such as bearings, gears, shafts, etc.

4.Furniture manufacturing: Cold-rolled strip steel is used in furniture manufacturing to make tables, chairs, cabinets and other furniture products.

5.Chemical equipment: Cold-rolled strip steel is often used to manufacture containers, pipes, valves and other components of chemical equipment.
