Product Description:

Construction building material galvanized color prepainted cold

rolled steel coil

 

Prepainted steel sheet is coated with organic layer, which provides higher anti-corrosion property and

a longer lifespan than that of galvanized steel sheets.

 

The base metals for prepainted steel sheet consist of cold-rolled, HDG electro-galvanized and hot-dip

Alu-zinc coated. The finish coats of prepainted steel sheets can be classified into groups as follows:

polyester, silicon modified polyesters, polyvinylidene fluoride, high-durability polyester, etc

Q:Charcoal classification
Hard charcoal. By hardwood such as Fagaceae Quercus, Castanopsis trees, secondary birch and etc..Broad-leaved charcoal. Charcoal made from a mixture of hard and soft hardwood.Pine charcoal. Carbon fired from pine or other needle wood. In addition to bamboo and bamboo charcoal burning with shells, stones (coconut shell, peach stone charcoal etc.) wood raw material firing. Charcoal collected from household stoves in the cell known as carbon. If the charcoal is crushed and mixed with proper adhesive, and then pressed, formed and roasted, the deposit is made. According to the burning process of silica and carbon black.
Q:What is the HS number for billet export?
Your specification 13*13*6 or 12 meters, this is a square cross section, so 7207120000 this can not be used, your billet carbon content is 0.17 to 0.23% less than 0.25%, so we must use the following7207190000 Other Billets with carbon content less than 0.25%Export tax refund: 0%MFN country of import tariff: 2%General customs duties: 11%Export tariff rate: 0%VAT: 17%
Q:How are the billets classified?
According to the specifications are divided into: billets, billets, round billet, rectangular billet and slab. According to the steel grade: Q235, Q195, GCr15 and so on........................
Q:What about carbon 4 and carbon 5?
Carbon four is butane, which is made up of four carbon, divided into n-butane and isobutane.Carbon five is pentane, composed of five carbon, divided into pentane, isoamyl, and new pentane.A product of petroleum refining, usually consisting of alkanes with a greater number of carbon atoms.
Q:What is billet?
Mould blank and continuous casting billet: mould blank and continuous casting billet,
Q:Continuous casting billet has slag inclusion and air hole
the only way to avoid pinhole of slag situation.1, after foaming, a large amount of gas and residue are produced, which is the main source of porosity and slag inclusion in the cast steel.2, steel casting pouring system or ingate structure is not reasonable, easy to make the gas and residue involved in the liquid metal, the formation of porosity and slag.3, pouring temperature is too low, can not make the cast steel parts of the gas and residue fully excluded, floating up to the top of the casting, but also easy to produce porosity and slag inclusion.4, in some parts of the cast steel parts, when the permeability of the paint is very low, due to the role of gas back pressure, it is easy to make the gasification gas wrapped in the epidermis, forming a package of gas".
Q:What is the difference between carbon three plants and carbon four plants?
Also known as C4 plants. Such as corn, sugar cane, sorghum, amaranth and so on.CO2 is the first product of the assimilation of photosynthetic carbon cycle in three carbon compounds 3- phosphoglycerate plants, known as carbon three plants (C3 plants), such as wheat, soybeans, cotton, tobacco, etc.. C3 plants have higher CO2 compensation points than C4 plants, so the survival rate of C3 plants is lower than that of C4 plants when the CO2 content is low.By contrast, the division of C3 plant cells is less definite than that of C4 plants, and CO2 uses less efficiently. To some extent, C3 plants may be considered as prokaryotes in plants, whereas C4 plants are more like eukaryotes".
Q:What does the billet of the steel plant refer to?And steel what is the difference?
Billet is the product of molten steel made by steelmaking furnace. After casting, the billet can be divided into two kinds: casting blank and continuous casting billet. At present, the casting process has been basically eliminatedRefers to the use of reinforced and prestressed concrete with steel reinforced concrete, the cross section is circular, sometimes square with rounded corners. Including round bars, ribbed steel bars, steel torsion bar.
Q:How to calculate the cost price of billet?
That depends on what kind of material you are producing steel billet, and are generally the city's iron ore came.
Q:How many tons of billets does it take to produce a ton of thread steel?
Domestic steel manufacturers, production rate of about 97%, so probably need 1/97%=1.03 tons. The yield was increased, consumption will be reduced.
