Product Description:

1.Structure of Cold Rolled Steel Description:

The raw material of cold rolled steel coil/sheet is high quality hot rolled product, and after pickling continuous rolling, degreasing, annealing,skin pass,slitting and cut to length line etc. Along with it many kinds of new  technology and new process of global cold rolling production have been applied. Therefore the quality of the goods could be guaranteed. The product is widely used in outdoor and interior decoration, furnishing manufacturing, home appliance, automobile etc. it has a lower melting point than steel and good castability properties.[1] Certain compositions of cast iron, while retaining the economies of melting and casting, can be heat treated after casting to make malleable iron or ductile iron objects. Steel is also distinguishable from wrought iron (now largely obsolete), which may contain a small amount of carbon but large amounts of slag.

2.Main Features of the Cold Rolled Steel

• Excellent process capability

• Smooth and flat surface

• Workability, durability 

• Excellent heat resistance performance

 High strength

 Good formability

• Good visual effect

Q:Is the coil strip? Is hot rolled coil and hot rolled strip the same?
We found differences between strip and hot rolled strip width is below 1000mm, so it can be distinguished by the Ruifeng strip and Wuhan specifications eye coil, as to why some people use a strip coil, it depends on their factory mill can tie what width, this demand is also different.
Q:What's the difference between hot rolled strip and cold rolled strip? What's the difference between hot rolled coil and cold rolled coil?
The term "steel coil" is strip steel whose width is greater than 600mm and its width is less than 600mm. It is called "narrow band", so hot rolled coil is called hot rolled strip steel. As for the difference between hot rolled coil and cold rolled sheet, it is aimed at the rolling state of the steel plate. The hot rolled coil is made by rolling the hot rolled slab.
Q:What are the categories of strip steel? How do you distinguish it?
Steel is divided into two major categories: carbon steel (carbon steel) and alloy steel by chemical composition. Carbon steel is an alloy obtained by smelting pig iron. Besides iron and carbon, it also contains a small amount of impurities such as manganese, silicon, sulfur and phosphorus. Carbon steel has a certain mechanical properties, but also has good technical performance, and low prices. Therefore, carbon steels have been widely used. But with the rapid development of modern industry and science and technology, the performance of carbon steel has not fully meet the needs, so people have developed a variety of alloy steel. Alloy steel is a multicomponent alloy obtained by adding certain elements (called alloy elements) on the basis of carbon steel. Compared with carbon steel, the properties of alloy steel have been improved greatly, so it has been widely used.
Q:What is the difference between cold plate and strip steel?
The strip is supplied in general, and has the advantages of high dimensional accuracy, good surface quality, easy processing and material saving. Same as steel plate, strip steel is divided into two kinds of ordinary strip steel and high quality strip steel according to the material used. Two kinds of hot-rolled strip steel and cold rolled strip steel are processed according to processing method.
Q:What is the difference between steel strip and strip steel?
The steel strip is the product which the processing enterprise cuts the strip steel according to the specific machine size to cut into a certain length, the width, generally assumes the enclosed circle shape. For example, steel conveyor belts, such as furniture or wood processing enterprises, "band saw" saw blade, but also steel band.
Q:1 can thick galvanized steel square pipe burn welding?
Galvanized square is a hot-rolled or cold-rolled galvanized steel or galvanized sheet for the blank shape by the cold bending process after section steel pipe welded square hollow square cross-section shape and size of the high-frequency; or the cold hollow steel well in advance of the re galvanized square by galvanizing processing of pipe.
Q:The degreasing time is too long, will the strip surface be oxidized?
Sheet metal pretreatment, degreasing total alkalinity is recommended in 15-20, alkali spent large, must be short time processing, for a long time will make the metal crystal nucleus passivation, influence phosphating film. Sheet metal general oil should not be cleaned, especially stamping parts, etc., it is recommended to use degreasing temperature, the temperature can be 65-75 degrees.
Q:The relation between hot rolled strip and cold rolled coil, hot rolled strip and cold rolled strip
Hot rolled strip: hot rolled strip, also known as hot rolled strip, commonly known as hot plate. Hot rolled strip with width less than or equal to 600mm, steel plate of thickness 0.35-200mm and steel strip of 1.2-25mm thickness. The strength of hot rolled steel plate surface quality is relatively low, almost (oxidation low smoothness), but good plasticity, general plate, cold-rolled plate, high strength, high hardness, high surface smoothness, generally can be used as a punching sheet, plate.Cold rolled strip: cold rolled strip and sheet, general thickness of 0.1 ~ 3mm, width of 100 ~ 2000mm, all with hot rolled strip or steel plate as raw material, at room temperature by cold rolling rolling
Q:What is the difference between strip steel and silicon steel?
The sheet material rolled with silicon steel is the most widely used soft magnetic material in the field of electrical engineering. Therefore, silicon steel sheet is also called electrical steel sheet. Silicon steel sheets are widely used in motors, generators, transformers, chokes, electromagnetic devices, relays and measuring instruments. Influence of silicon content on properties of silicon steel sheet. Silicon is a good deoxidizer for steel. It combines with oxygen to convert oxygen into a stable, non carbon reduced SiO2, avoiding lattice distortion of iron by doping oxygen atoms. Silicon becomes a solid solution in alpha iron, increasing resistivity and helping to separate harmful impurities from carbon.
Q:Hot rolled strip and hot rolled strip are also sealing plates? What's their function?
Secondly, strip and steel strip should be about the same, no less than a narrow strip of steel bar, the equipment configuration is the same
