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.

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 does the aluminum foil bag recycle?
The paper box should be thrown to "container",and the aluminum foil bag should also be thrown to "container".the 20% of paper and the 5% of the plastic film should be disposed.the aluminum foil paper also need to be disposed together with the paper and plastic film.the rate of recycle disposal should be reached in the range of 40% to 50%.The PE part of aluminum foil is disposed by the incinerato. Then the disposed material should sent to waste plant.
Q:It is an alloy of aluminum foil?
Because aluminum is soft, ductile, with silver-white luster, if the sheet after the rolling, sodium silicate and other material mounted in offset paper made of aluminum foil, but also for printing. But the aluminum foil itself is easily oxidized and darkened, friction, touch, etc. will fade, so does not apply to long-term preservation of stamping book cover or the like.
Q:What's the application field of aluminum foil?
Aluminum foil can be used to roast fish and meet, pack dim sum and snacks, reserve leftovers, decorate items and clean.
Q:How aluminum foil is uesd in pharmaceutical packaging?
Traditional Chinese medicine tablets, powders, capsules, tablets balls packaging, is gradually moving from paper bags, simple plastic bags, glass bottles into plastic blister pack. blister pack with moisture, easy to carry, safety and health, etc., with the the development of sustained release pharmaceutical technology, the market will be more broad. currently the annual demand for aluminum foil blister packs of more than 7000 tons in 2005 is expected to exceed 10,000 tons.
Q:Why doesn't Aluminum Foil get hot even when its in the oven?
It does got hot. Aluminum is an excellent conductor of heat. Because of this, and foil is very thin, it loses its heat rapidly as well.
Q:Gaiam Aluminum Water Bottle question?
Aluminum okorder.com... an excerpt from the link above: The effects of Aluminum Aluminum is a well documented neurotoxin... causing a change in the replication rate or decreasing the metabolic rate of the cell
Q:FIBERGLASS BATT vs REFLECTIVE ALUMINUM SHEET?
The reflective aluminum will only have an R value of about 3 (for 1/2), R19 would be better. That would get you to R38, which is good. The existing should have a vapor barrier installed toward the ceiling, your added insulation should not have a vapor barrier. Either buy unfaced or remove the facing before you place it. The vapor barrier issue is another reason not to use the foil backed sheets, you don't want to trap any moisture inside your existing fiberglass. As for the window, aluminum would be better at reflecting the radiant heat if you can live with the appearance from the outside. I would still avoid foil backed foam, as it tends to deteriorate when exposed to light and can give off some nasty chemicals. Perhaps just plain aluminum foil affixed with spray adheasive? There is a bubble foam available as well, but it usually comes in large rolls. Painting the window over would be an option as well. Probably would look a bit better from the outside. Clean well with glass cleaner, dry completely. Glass cleaner has ammonia which can react with paint. NO PRIMER. I know that sounds weird, but when painting glass primer can cause the top coat to peel. Two coats of paint. (Painting on glass is actually one field test that we use to test the adhesion of a batch of paint.) Any light color should give the desired effect. Another thing that may help would be to vent the area above the ceiling. This may or may not be practical, but it sounds like heat is being trapped there with no way to escape.
Q:What's the difference between aluminum foil paper and tin foil paper?
Tin foil paper is a filmed metallic paper coated with something like silver, such as the metallic paper used for cigarette packaging. The color is silver. aluminum foil paper is a metallic paper by bonding the slip sheet of aluminum foil and aluminum foil paste. It is used for food damp proof and packaging. Both can be used for cooking and package.
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:Metalic Finish On Aluminum?
If you want to use aluminum, just polish the aluminum using steel wool. Use the coarsest or finest to suit your needs.
