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

5.FAQ of Cold Rolled Steel 

We have organized several common questions for our clients,may help you sincerely: 

1.How about your company?

A world class manufacturer & supplier of castings forging in carbon steel and alloy steel,is one of the large-scale professional investment casting production bases in China,consisting of both casting foundry forging and machining factory. Annually more than 8000 tons Precision casting and forging parts are exported to markets in Europe,America and Japan. OEM casting and forging service available according to customers requirements.

2.How to guarantee the quality of the products?

We have established the international advanced quality management system,every link from raw material to final product we have strict quality test;We resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.

3. How long can we receive the product after purchase?

Usually within thirty working days after receiving buyers advance payment or LC. We will arrange the factory manufacturing as soon as possible. The cargo readiness usually takes 15-25 days, but the shipment will depend on the vessel situation.

Q:Is the coil strip? Is hot rolled coil and hot rolled strip the same?
As for the "Q235" mentioned below, this steel can not be deformed under the pressure of 235 MPa and is used to represent the material of steel. Similarly, Q195 is naturally deformed at 195 MPa pressure.
Q:What is the hardness of cold rolled steel strip?
The thickness of cold rolled strip and sheet is 0.1 ~ 3mm, and the width is from 100 to 2000mm. The products are made of hot rolled strip or steel plate and rolled in cold rolling mill at room temperature. Cold rolled strip and sheet have the advantages of smooth surface, smooth surface, high dimensional accuracy and good mechanical properties. Most of the products are formed into rolls, and a large part of them are processed into coated steel plates. The roll cold rolled sheet has the advantages of high production efficiency, convenient operation and favorable follow-up processing. Therefore, widely used, it has gradually replaced the same thickness of hot rolled sheet. Only a small number of cold rolled alloy sheets for special purposes are rolled by single plate. The production of cold rolled strip and sheet steel accounts for about 30% of the total output of steel in developed countries. In addition to ordinary carbon steel, there are silicon steel, stainless steel and alloy structural steel, etc..
Q:Steel industry, strip 195, where can strip be used?
Q195 carbon content is low, the strength is not high, plasticity, toughness, processing and welding performance is better.
Q:What is the cause of the deviation of the strip in the rolling process? How to deal with it?
Because of the sudden decrease or disappearance of the tension of coiler during the rolling process, the strip is running off and breaking.
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 about the strip scraping in the annealing furnace?
Thus forming an air knife scratch. This kind of defect causes the product to be wasted because the coating is scratched. Proper control of strip tension in productionForce and adjust the nozzle distance, can avoid this kind of defect happen.
Q:What are the high speed steel strips and material specifications?
High precision (H) and wide and high thickness accuracy (KH) four kinds of strip steel. According to the material condition, two kinds of strip can be divided into chilled and annealed, the former has higher strength and the latter has good plasticity and toughness.
Q:Where is the lining board made of polyurethane lining? Please contact immediately
The flame retardant and antistatic performance, has direct relationship with the selection of additives in the domestic production and sales of all kinds of additives manufacturers and enterprises thousands, but those additives in line with our formulation requires, for internal performance we use without affecting the polyurethane? Pengbosheng company has done numerous tests, try hundreds of flame retardant in different and antistatic agent, screened from for our formulation system of auxiliaries. Selecting the proper amount of additive can not only give full play to the performance of the assistant, but also achieve the design indexes of flame retardance and antistatic, and can not lose the superior performance of polyurethane.
Q:Can the tension leveller eliminate the wave shape of strip steel completely?
We take the longest and shortest fibers in the cross section of the strip and analyze their elastic and plastic deformations under the action of tension. In addition to external force because of tension by strip in straightening process, and bending stress and bending stress is tensile stress and compressive stress of the component, and the main role is tensile stress, the main deformation so through the analysis of tensile deformation on behalf of strip.
Q:What is the difference between steel strip and coil?
What do you think of rolling mills, not money ah, rolling strip is a small rolling opportunities, can be cheaper than rolling coil, and this cost should be spread to each product above, there are other what, like the cost of sharing ah.
