Q:What are the advantages of cold rolling and cold rolling strip steel?
What to do with cold rolling is better than that of hot rolling, which is the main one because cold rolling is processed by hot rollingCold: hot rolled steel coil as raw material by pickling descaling after cold rolling, the finished rolling hard volumes, due to continuous deformation caused by cold hardening the volume rolling hard strength, hardness, toughness index rise decline, so the stamping performance will deteriorate, only for a simple deformation of parts.Cold rolled steel strip and sheet thickness is generally 0.1 ~ 3mm, width 100 ~ 2000mm in hot strip steel or timber as raw material, under normal temperature after cold rolling, cold rolled steel strip and sheet has the advantages of smooth surface, smooth, high precision and good mechanical properties.
Q:What's the meaning of "double light" in strip cold rolling?
Strip strip coiling: general supply, with high dimensional accuracy, good surface quality, easy processing, material saving and other advantages. With the same steel plate, strip by strip material is divided into ordinary and high quality strip two; according to the processing method of cold rolled strip steel hot strip, two.
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 does galvanized steel strip A6 mean?
The difference between the two is that one zinc plating, one without plating, the other with zinc, is more resistant to oxidation and corrosion
Q:Why is strip heat cheap?
The strip is a narrow strip of steel that can be used in a refinery, or not. This is the answer you need
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: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.
Q:What's the difference between cold rolled strip and cold rolled strip?
Cold rolled steel sheets are made from hot rolled sheets at normal temperatures. Although they are rolled during processing, they can also cause steel plates to heat up. Nevertheless, it is called cold rolling. Because of the cold rolling of continuous hot rolling, the mechanical properties are poor and the hardness is too high. It must be annealed to restore its mechanical properties. Rolled rolls are generally used to make products without bending or stretching.
Q:Where is the lining board made of polyurethane lining? Please contact immediately
I don't know where to use it,Wear resistant lining board is based on the use of the environment and requirements for the product design, the earliest silo chute used in wear-resisting lining board is made of PE material fabrication and installation, but in use, PE liner wear, service life, leading to the use of units often change, very inconvenient, but also affect the normal purchase and shipment. PE material hardness is very high, food and other food raw materials in the process of loading and unloading, and PU lining plate contact parts, food will be a large number of broken, seriously affecting the quality of grain. Therefore, polyurethane wear-resistant lining board arises at the historic moment. Polyurethane wear-resistant lining board, as an elastomer product, has very high abrasion resistance and resilient cushioning performance.
Q:Pickling process of cold rolled strip
The pickling section can be divided into two ways: sulfuric acid pickling and hydrochloric acid pickling, but because hydrochloric acid pickling has more advantages, we can explain it by the acid washing mechanism of hydrochloric acid.The chemical reaction between hydrochloric acid solution and iron oxide scale is:FeO + 2HCl = FeCl2 + H2OFe2O3 + 6HCl = 2FeCl3 + 3H2OHydrochloric acid solution can quickly dissolve all kinds of oxide scales, pickling reaction can be carried out from the outer layer. Hydrochloric acid pickling is mainly chemical corrosion, and hydrochloric acid pickling is very harmful to metal matrix. Therefore,The structure is not sensitive to the efficiency of acid pickling of iron oxide scales, and the steel surface after pickling clean silver. The rate of acid washing reaction is closely related to the degree of cracking of strip iron before picklingOff.
