Package & Delivery of Hot Rolled Checkered Steel Plate from China CNBM:

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 from China CNBM:

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:What's the difference between PTP aluminum foil and conventional soft packing used aluminum foil?
PTP aluminum foil can't resist high temperature while conventional soft packing used aluminum foil does.
Q:Aluminium daily maintenance need to pay attention to what matters?
1.aluminum during storage, is strictly prohibited and chemical materials and wet materials are stored together 2.aluminum during transport, must be covered with a tarpaulin to prevent rain, snow intrusion;
Q:Why is the aluminum foil in the lithium ion battery eroded ?
During reverse charging, capacitance works as primary cell with two other power supply shorted. This means aluminum as the negative pole will react with the electrolyte, thus being eroded. Aluminum foil can not work as the negative pole, for Li and Al will alloy with each other at low voltage. The hard oxidation film covering the surface of the aluminum product will prevent itself from further oxidizing. On the contrary, oxygen and water can still react with Iron through the rust. Therefore, aluminum is more active than Iron, but it has better anti-corrosion abilities.
Q:How to tear the aluminium paper package neatly by handy techniques
Use the rule to press the tin paper and use box cutter to cut the paper in right size.
Q:Why the wall insulation aluminum foil is put in the warm side
Putting in the warm side can save the energy and equal to the temperature preservation ratio: In winter,the temperature preservation aluminium is in the interior side of wall in the north.when the temperature of wall rises, the temperature of room is comfortable and the energy consumption is reducing. If putting in the exterior side of wall, the temperature in the room can be risen only after the wall temperature being rising, and the energy consumption is increasing.
Q:How to eliminate static in aliminum foil bag?
Aluminum foil bag can protect electrostatic sensitive components from electrostatic potential hazards to the highest degree. They unique four-layer structure can form an inductive cover to make things in bags isolate from static electric field. Furthermore, the inner layer is made low density polyethylene which can remove the static can avoid static generation inside the bag. This kind of hot sealable bag is translucence , so the good inside can be easily recognized outside and the product bar code can be read. It's mainly used in package of electronic elements and PC board. It can also be used in packaging industry.
Q:What are the classification of aluminum foil compound insulation material?
There are a variety of insulation materials with wide application. The commonly used ones include glass cotton products, heat insulation blankets and heat-insulated foam glass, polyurethane foam glass, etc. The glass cotton products are used in air conditioning insulation, duct insulation, polyurethane foams, extruded polystyrene board, molding of polystyrene, Bakelite resin, mineral fiber products, polyphenyl granule size, compound wood, soft wood, etc. Polyurethane foam is currently a kind of insulation material with minimum coefficient of heat conductivity of 0.018~0.024W/(m·k)in building insulation.
Q:What are the advantages of carbon-coated aluminum foil in lithium battery applications?
3. To improve consistency, increase the cycle life of the battery; 4. improve the adhesion of the active material and current collector, a pole piece reduce manufacturing costs; 5. The collector protection against corrosion electrolyte;
Q:What is the thermal insulation principle of aluminum tape?
Heat is transferred by convection, conduction and radiation. Aluminum tape often is used for wrapping the thermal insulation layer and its silver surface can block heat radiation. Since aluminum is a good conductor of heat, wrapping the tape with aluminum foil does quicken the heat loss instead of heat preservation. Therefore, it's better to wrap with heat-insulated cotton before wrapping with aluminum foil. Actually the thermal insulation cotton preserves heat rather than the aluminum foil which serves as a conductor to outside temperature to protect the inside temperature. It is featured by thermal insulation, waterproofness and corrosion resistance. Due to its extremely low absorption coefficient solar radiation, it can isolate from most of the heat transfer. Introduction to several major products of aluminum foil.
Q:How to prevent foil wrinkling?
Since the rolling Aluminum often bear greater than after the order processing tension, some rolling showed only bad plate-shaped cut in the use of aluminum foil or annealed Shique showed wrinkling. The main reason is due to wrinkling produce bad shape control, including roll grinding incorrect, unreasonable control roll, rolling and cutting process parameters is unreasonable, incoming bad flatness and flatness adjustment is not correct, set or lack of precision cylindrical die.
