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:How can the offset film affixed to the cold-rolled steel sheet be removed?
- 1, with paper towels stained with some alcohol (preferably with industrial alcohol, not to use medical also OK) wipe, and then rub a few times on the clean.2. Use acetone. Method ibid. Less and thoroughly, and best of all, it removes the residual gum quickly, easily, and more efficiently than the essence.
- Q:Is galvanized steel plate fire-resistant?
- Should be refractory, but the melting point of zinc relative to steel is relatively low, 420 degrees or so, if higher than this temperature, galvanized layer will be destroyed, the bottom plate is no problem.
- Q:What's the difference between single rolling steel sheet and continuous rolling steel plate?
- Single rolled steel plate usually refers to medium plate, in the process of rolling and finishing, the plate has been flat, usually thicker (6mm or more), the width of the fastest up to 4800mm.
- Q:Is 5mm thick steel plate tapping M8 thread reliable?
- With 5mm steel plate upside M8 thread, with M8 screw, that depends on what you use it to do? Check the strength of the screws at M8 (different grades, different intensities) to see if you are reliable and unreliable.
- Q:What is the difference between a steel strip and a coil? The steel strip is flat steel, and the steel coil is made of steel. Is that correct?
- A steel strip is also a coil, usually a narrow strip, also known as a steel strip.
- Q:The differences and uses of cold rolling and hot rolling
- Cold rolled forming steel allows partial buckling of the cross section, thus taking full advantage of the post buckling capacity of the member, while the hot-rolled section does not allow partial buckling of the cross section.
- Q:What material can be replaced by 345D steel plate?
- Higher than its level of material of steel plate can replace.Q345D. yield in more than 345 of the steel.D class -20 degree of shock. Can replace the Q370D.Q390D.Q420D.Q460D.Q550D.Q690D., generally in engineering machinery can be higher generation low
- Q:What's the difference between steel plate 20 and Q235 steel plate?
- Q235 steel yield point is 235MPa, the elongation is 21-26%; widely used in the production of general machinery parts have certain strength and elongation, such as pin, shaft, rod, connecting rod, ring, bolt, nut, cylinder, gear, rack, rack and welding parts.
- Q:Are there any restrictions on the thickness of the steel plate, such as the minimum thickness of the steel plate?
- No minimum, no maximum, no requirements, what kind of plate can be welded, but the welding method is not the same as welding equipment.
- Q:How do you calculate the square footage of a ton of steel?
- It is made of molten steel and cooled and pressed into flat steel.The steel plate is flat, rectangular, and can be rolled directly or cut from a wide strip of 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 according to rolling.
