Product Description:

1.Structure of Prepainted Galvanized steel Coil :

With Gi as base metal,after pretreatmet (degrease and chemical treatment) and liquid dope with several Layers of color,then after firing and cooling,finally the plate steel is called pre-painted galvanized steel ( PPGI) .Pre-painted galvanized steel is good capable of decoration ,molding,corrosion resistance lowering the cost of production and increasing the quality of the metal. Today, steel is one of the most common materials in the world, with more than 1.3 billion tons produced annually. It is a major component in buildings, infrastructure, tools, ships, automobiles, machines, appliances, and weapons. Modern steel is generally identified by various grades defined by assorted standards organizations.

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 strip and coil?
The coil is a thin steel sheet with a thickness of not more than 6 mm, usually less than 3 millimeters, but is rolled with a large mill due to its wide width. The width of the rolled strip is no more than 0.2 meters; the mill used is small, of course, the same thickness of the same material, the price of the coil is also more expensive than strip.
Q:What is the cause of the deviation of the strip in the rolling process? How to deal with it?
Strip edge control device, fault, deviation device, tube or mirror surface pollution or other objects covered, so that the deviation of the device failure, resulting in the first line of deviation
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
Q:Can the tension leveller eliminate the wave shape of strip steel completely?
Reflecting the shape of the board, the wave height is reduced or the wavelength is lengthened. That is, the tension straightener can only reduce the wave and improve the shape of the plate, but can not fundamentally eliminate the wave, and get an ideal smooth strip steel. There is an old saying called "correction must be positive". That is to completely eliminate the wave must be of short fiber than long fiber tension and bending is greater, elastic and plastic deformation of the original long fiber length is greater than a certain amount, resulting in the removal of external force, elastic recovery, length of fiber length, so as to obtain the shape completely flat the. However, in the current conditions of the straightening machine equipment, do not have such a function.
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:Is there any difference between galvanized steel strip and galvanized sheet?
Galvanized steel strip, in narrow sense, refers to strips of steel.
Q:Where is the good quality of galvanized steel strip?
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, and two kinds of hot-rolled strip steel and cold rolled strip steel according to processing method.
Q:The relation between hot rolled strip and cold rolled coil, hot rolled strip and cold rolled strip
Cold rolled coil (annealed): hot rolled coil obtained by pickling, cold rolling, batch annealing, flattening, and finishingThat is, the biggest difference between hot rolled coil and cold rolled coil is that the heat treatment process is different. (annealing process)Compared to the specific heat roll, the cold-rolled roll has a bright surface and a high degree of finish, but it produces more internal stress and is often annealed after cold rolling.
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.
