Product Description

Product Description


The materials used for color coating coils are cold-rolled substrates, hot-dip galvanized substrates, electro-galvanized substrates, and galvanized substrates. In addition, it is a color-coated steel strip using hot-dip galvanized steel strip as the base material. In addition to the protection of the zinc layer, the organic coating on the zinc layer plays a covering and protective role to prevent the steel strip from rusting, and its service life is longer than that of the galvanized strip. long, about 1.5 times. With its many advantages above, color-coated coils are widely used in various industries such as construction, home appliances, automobiles, furniture and light industrial products.

The interrelation between cold rolling and hot rolling


Hot rolled

Hot rolling is made of slab (mainly continuous casting billet) as raw material and made of strip by roughing mill and finishing mill group after heating. From finishing the last hot steel strip mill out through laminar flow cooling to the set temperature, which consists of the winder coil, steel coil after cooling, according to the different needs of users, with different finishing line (flat, straightening, transverse or longitudinal cutting, inspection, weighing, packaging and logo, etc.) and become a steel plate, flat roll and longitudinal cutting steel strip products. To put it simply, a slab of steel is heated (like the red, hot block you see on TV) and then subjected to several rounds of rolling, cutting and straightening to form a sheet of steel. This is called hot rolling.

Cold rolled

Cold rolling: using hot rolled steel coil as raw material, after removing the oxide scale by pickling cold rolling, the finished product is rolled hard coil, due to cold hardening caused by continuous cold deformation, the strength and hardness of rolled hard coil increases, the toughness and plastic index decreases, so the stamping performance will deteriorate, can only be used for simple deformation of parts. Hard roll can be used as raw material for hot-dip galvanizing plant, because hot-dip galvanizing unit is set with quenching line. The hard roll weight is generally 6~13.5 tons. The steel roll is continuously rolled on the hot pickling roll at normal temperature. The inner diameter is 610mm.

Product features: Because there is no annealing treatment, its hardness is very high (HRB > 90), the mechanical performance is very poor, can only carry out simple directional bending less than 90 degrees (perpendicular to the direction of coiling).

To put it simply, cold rolling is processed and rolled out on the basis of hot rolled plate rolls. Generally speaking, it is hot rolling - pickling - cold rolling such a process.

Cold rolling is made of hot rolled plate at room temperature, although the steel plate will be heated by rolling during the process, but it is still called cold rolling. Due to the cold rolling after continuous cold rolling, the mechanical properties are poor and the hardness is too high. Must undergo annealing to restore its mechanical properties, no annealing is called rolling hard coil. Rolled hard coil is generally used to do without bending, stretching products, thickness 1.0 or less rolled hard on both or four sides of the lucky bending.

1. Cold rolling is made of hot rolled plate at normal temperature

2. A slab of steel is heated (like the red, hot block you see on TV) and then subjected to several rounds of rolling, cutting and straightening to form a steel plate. This is called hot rolling.

Hot rolled sheet has low hardness, easy processing and good ductility.

Cold rolled sheet hardness is high, processing is relatively difficult, but not easy to deformation, high strength.


Hot rolled plate strength is relatively low, surface quality almost (oxidation, low finish), but good plasticity, generally medium thick plate, cold rolled plate: high strength, high hardness, high surface finish, generally thin plate, can be used as stamping plate.

Hot rolled steel plate, mechanical properties are far inferior to cold processing, also inferior to forging processing, but has better toughness and ductility

Cold rolled steel plate due to a certain degree of work hardening, low toughness, but can achieve a good flexural ratio, used for cold bending spring pieces and other parts, at the same time because the yield point is closer to the tensile strength, so the use of danger is not predictive, when the load exceeds the allowable load is prone to accidents

Supplement, cold rolled steel plate 0.3-3.0mm, hot rolled steel plate 2.0-


How to judge steel coil material


Ordinary according to the amount of carbon C difference, low carbon steel, high carbon steel, the most commonly used is 45 steel. All with the letter C, C45, middle carbon... Other letters are based on the content of the elements, general letters represent elements, numbers represent percentage content, low carbon boiling steel, generally can be replaced by 10 steel.

08F features and scope of application:

It has low strength, soft steel, good plasticity and toughness. General use does not require heat treatment, but in order to eliminate the internal force caused by cold processing and improve the cutting performance of steel, heat treatment can be carried out, cold processing can increase the strength. It is often used to manufacture stamping parts and carburizing parts, such as stamping products, sleeves, enamel products, car shell and so on.

1 Chemical composition:

Carbon C: 0.05 ~ 0.11

Silicon Si: ≤ 0.03

Mn: 0.25 ~ 0.50

Sulfur S: ≤ 0.035

P: ≤ 0.035

Cr: ≤ 0.10

Nickel Ni: ≤ 0.25

Cu: ≤ 0.25

2 Mechanical properties:
