Main Feature of Z38 BMP Rolled Steel Coil Construction Roofing Construction

1) Excellent corrosion resistance: The zinc layer provides a good protection of Pre-painted Galvanizeed Steel Sheet.
2) High heat resistance: The reflective surface of the material aids in efficiently reflecting the sunlight away and in turn reducing the amount of heat transmitted. The thermal reflectivity converts into energy savings.
3) Aesthetics: Pre-Painted Galvanized steel sheet is available in plethora of patterns and multiple sizes as per the requirements that given by our customers.
4) Versatility: can be used in the various areas.
Standard seaworthy export packing: 3 layers of packing, inside is kraft paper, water plastic film is in the middle and outside GI steel sheet to be covered by steel strips with lock, with inner coil sleeve.

Q:What are the common defects in billet? What's the cause?
Three, radiographic inspection, surface defects; 3, 2, other defects, not welded and welded, undercut;Three, cold crack and fluorescence test;Four common welding defects are: 1; 4; 2:A;
Q:Reasons and treatment methods of billet stripping in continuous casting
The main reason for the stripping is that the slab is not uniformly cooled in the mold, which results in uneven thickness of the shell, which results in uneven shrinkage, which leads to the unevenness of the billet. If the mould outlet, two cold area is uneven, the shell support is not full, it will make breaking-off intensified;
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:Billet heating furnace billet temperature reached, steel will be adhesion
As soon as the melting point is reached, the part melts before sticking. But heating will swell a lot, you need to leave enough space.
Q:What is the difference between steel and billet in the process?
Square is a square steel hollow, with iron produced; but it is a square steel billet is generally solid, forging or casting molding.
Q:What is the difference between continuous casting billet and cast billet?
but with high-grade continuous casting line (full protection casting, electromagnetic stirring, liquid stopper control) compared both have a big difference in the crystal, oxidation, surface quality.
Q:What is carbon accumulation?
Generally refers to the polycarbonate, PC, is a kind of thermoplastic plastics, good transparency, good mechanical properties, surface hardness, common uses such as CD, plastic glasses, a fence, protective window, public places, vacuum cleaners, coffee machine, juicer barrel, refrigerator shelf, pure such as the bucket.
Q:What is Alfa carbon? What is beta carbon?
Alfa is directly connected with the functional groups of carbon atoms of carbon atoms, such as CH3CH2COOH CH2 in which methylene propionate is Alfa carbon carbon carbon atom is the beta carbon atom is directly connected with the functional groups and the connection of the carbon (around Kazakhstan), such as the CH3CH2COOH CH3 propionic acid methyl carbon is the beta carbon
Q:How to purchase suitable billet heating furnace
Billet heating furnace manufacturers are many, the procurement of cost-effective equipment is the user's best choice. Choice can not be blind, you can not just look at the price, the choice of advice you consult more manufacturers, and then use the exclusion method to determine your final goal. Online can take a look at live video, more reference.
Q:Billet production process
Two is the steel ingot produced by the steelmaking system or the continuous casting billet processed by the rolling equipment of the steel rolling system, and the three is the semi-finished product processed by the forging equipment of the steel ingot produced by the steelmaking system.
