Applications of Hot Rolled Checkered Steel Plate:

1.Definition: The hot rolled steel sheet with raised pattern on surface. The raised pattern could be shaped as rhombus,bean or pea. There is not only one kind of pattern on the checkered steel sheet, but also a complex of two or more than two kinds of pattern on surface of one checkered steel sheet. It also could be called as grid steel sheet.

2.Character: The Hot Rolled Checkered Steel Plate possesses a variet of advantages, such as beauty in appearance,skip resistance and saving steel material.Generally speaking,in order to test the mechanical property or the quality of hot rolled checkered steel sheet, the shaping rate and the pattern height should be tested primarily.

3. In conclusion, the hot rolled checkered steel plate can usually be used in the industry of ship-building,boiler,automobil,tractor,train- building and architecture. In details, there are many demands for hot rolled checkered steel plate to make floor,ladder at workshop,work frame pedal,ship deck,car floor and so on.

 

Package & Delivery of Hot Rolled Checkered Steel Plate:

1. The items to be prepared for packing include: narrow steel strip, crude steel belt or edge angle steel, kraft paper or galvanized sheet.

2. The hot rolled checkered steel plate should be wrapped with kraft paper or galvanized sheet ouside, and it should be bundled with narrow steel strip, three or two narrow steel strip in longitudinal direction,and the other three or two strips in transverse direction. Furthermore, in order to fix the hot rolled checkered steel plate and avoid the strip at edge shall be broken, the crude steel belt cut into square should be put under the narrow steel strip on the edge. Of course, the hot rolled checkered steel plate could be bundled without kraft paper or galvanized sheet. It depends on customer’s requirement.

3. In consideration of the transportaion from mill to loading port, the truck will be usually used. And the maximum quantity for each truck is 40mt.

4. All in all, we could do in accordance with customer's request.

Production Flow of Hot Rolled Checkered Steel Plate:

1.The steel raw materials are first melted in an electric furnace. They are subjected to at least 12 hours of intense heat.

2.The mixture is cast into either large rectangular blooms, slabs or bar-like billets, before taking on a semisolid form.

This initial form of steel is then processed via forming operations that include hot rolling into bars, wires, plates and slabs.

3.The steel is subjected to annealing. This is a heat treatment in which the metal is first heated and then cooled under extreme, controlled conditions. The metal is thus treated for internal stresses and is duly softened and strengthened. This processing is also referred to as 'age hardening'. It requires careful monitoring of temperature and heating and cooling times. The aging temperature affects metal properties massively; while lower temperatures cause high strength and low fracture toughness (i.e., more brittle than ductile), higher temperatures result in a tougher material of lower strength (i.e., more ductile than brittle). Rapid cooling can produce a tough steel with no significant loss in strength. The heat treatment given to stainless steel depends on the type and grade of steel being produced.

4. Annealing or the heat treatment can lead to the development of a precipitate, known as scale. The scale can be removed via several methods, such as pickling, (nitric-hydrofluoric acid bath),electrocleaning(application of an electric current, using phosphoric acid and a cathode), etc.

5. Descaling of the material is introduced into the manufacturing process at different times, depending on the type of steel being produced. While the bar and wire forms have to be additionally treated with hot rolling,forging and extruding, the sheet and strip forms go through annealing after hot rolling.

6. Cutting operations in the manufacturing process are essential in obtaining the desired shape and size of the end product. Mechanical cutting involves the use of guillotine knives and high-speed steel blades for blanking (punching out the shape by shearing) and nibbling (cutting out a series of overlapping holes). It is also cut via flame cutting, a process that involves the use of a flame generated by oxygen, propane and iron powder. The plasma jet cutting method uses an ionized gas column to melt and cut the metal.

6. Manufacturing end products involve further shaping via heat-rolling, pressing, forging and extrusion. The material is then joined via welding and given the desired shape.

Q:Is galvanized steel plate or iron plate?
Therefore, iron does not exist in practical applications. Another pure iron is very soft, or mechanical performance is not good, that is, if it does not oxidize, it can not be used. And we usually use the most is the iron carbon alloy, and the iron carbon alloy called "steel" in the metal, so from the academic angle to the iron carbon content is less than 0.008% that of iron, steel when the majority of coke, so the production process to burn the whole carbon is almost impossible to the. Therefore, the said carbon content is less than 0.008%, and iron can not be obtained by common iron making methods.
Q:What's the difference between low carbon steel and cold rolled steel?
It is usually used for cold rolled, low carbon steel for cold rolling, high carbon steel, generally not suitable for cold rolled steel plate, of course, this does not mean it completely just cold rolled steel of low carbon steel, because of the addition of alloy elements in all kinds of low carbon steel alloy steel can be different, such as P-added high strength steel, high strength low alloy steel after cold rolling after the steel is cold rolled steel grades, is just not the same.
Q:Must the welding between steel sheets be opened?
Not necessarily, very thin plate, no opening, but also guarantee penetration, but also through nondestructive testing
Q:What is the thickness of the paint board?
Paint boards are generally used in cabinets or doors and other places, we have often seen, but also understand some of the paint plate thickness of how much better? Paint board is a kind of woodworking materials. It is based on density board as base material, the surface after six to nine times (not the same as the number of Polish manufacturers are different, the more the number of process requirements is high, the cost is higher), the primer, drying, polishing (at the end of three, two, light) high temperature baked. At present, mainly used in cabinets, doors and so on. Paint board can be divided into light, Matt and metal paint three. At present, there are the latest engraving baking paint board, Newcastle house paint baking board and so on.
Q:Should the carbon fiber reinforce the steel bar on the side of the beam?
Not necessarily, mainly depends on how the design is calculated, usually put 100~200mm carbon fiber layering
Q:What does "Z" mean to the performance of steel?
To apply for Z steel plate thickness and subjected to tensile load on just the thickness direction has the performance requirements, it is in a certain level of structural steel (called parent steel) on the basis of the special treatment (such as calcium treatment, vacuum degassing, argon stirring etc.) and proper heat treatment steel.
Q:Steel plate pile length, adjacent two steel plate pile joints should be staggered what position?
If the joint in the same position, such as 9+9m then need to stagger joint position,Avoid stress in one position that results in joint fracture and deformation risk.
Q:Can the steel sheet pile retaining structure be watertight and impervious?
Steel plate: steel plate is made of molten steel, cooled and compressed into flat steel. Steel plate by thickness, thin steel plate <4 mm (thinnest 0.2 mm), thick steel plate 4~60 mm, extra thick steel plate 60~115 mm. The steel plate is divided into hot-rolled and cold-rolled parts by rolling.
Q:Stainless steel drawing plate, polishing plate, mirror panels of the three differences
Stainless steel wire drawing refers to: stainless steel wire drawing is stainless steel surface like filamentous texture, this is only a stainless steel processing technology. The surface is Matt, and carefully look at the above there is a trace of texture, but can not touch it.
Q:The difference between color steel and stainless steel
Color steel and stainless steel, stainless steel what is the difference? Color of the color is beautiful, diverse styles, economic and handsome, cheaper than stainless steel, the main difference is that the service life is about 3 years. Stainless steel is characterized by
