Structure of Prime quality square alloy steel billet 95mm Q235

 Prime quality square alloy steel billet 90mm Q235

Description of Prime quality square alloy steel billet 95mm Q235 

1. Prepainted steel coil is coated with organic layer, which provides higher anti-corrosion property and a longer lifespan than that of galvanized or galvalume steel sheets. 

2. The base metals for prepainted steel coil consist of cold rolled, HDGI Steel, electro-galvanized and hot-dip alu-zinc coated steel. The finish coats of prepainted steel coil can be classified into groups as follows: polyester, silicon modified polyesters, polyvinylidene fluoride, high-durability polyester, etc.

3. The production process has evolved from one-coating-and-one-baking to double-coating-and-double-baking, and even three-coating-and-three-baking.

4. The color of the prepainted steel coil has a very wide selection, like orange, cream-colored, dark sky blue, sea blue, bright red, brick red, ivory white, porcelain blue, etc.

5. The prepainted steel coils can also be classified into groups by their surface textures, namely regular prepainted sheets, embossed sheets and printed sheets.

Q:How are the billets classified?
Billet classification of GB, it is convenient to check
Q:Continuous casting billet has slag inclusion and air hole
1. Whether the injection hole before the casting is replaced with the protective slag instead of the special drainage sand, and whether the drain sand is dry or not2, whether it is too early to start adding protective slag is to protect the slag whether it is dry or not3, the opening of the mold to maintain the steel surface uniform and stable, rising to the required height, the key is fluctuation.
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 is the active carbon. What is the difference with the charcoal?
The chemical activation method. The activator of discharged gas, or by activating agent impregnated material, after the high temperature treatment can be activated carbon. The activated carbon has a microcrystalline structure, crystallite alignment completely irregular. The micro crystal (radius of less than 20, a: = 10-10 m), transition hole (radius 20 ~ 1000), big hole (radius of 1000 ~ 100000), so it has great inner surface, the surface area of 500 to 1700 meters / 2 grams.
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:Which is good for pure iron billet?
If you would like to consult more detailed information, I suggest you choose Shanghai far west special steel products Co., ltd..
Q:The reason for the blowhole in the billet to be pulled out by the continuous casting machine is 100
Production: 1 steel and 2 steel alloy or damp; for ladle lining refractory and no baking; otherwise the whole section are 3 billet bubble deposit if the situation is steel quality problems and the main problems of alloy billet; if the bubble is mainly between now and the relationship between process equipment (including continuous casting are clearly some problems of continuous casting machine the parameters of a)
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:Billet heating furnace prices?
Look at the video case, you can consult the advisory.
Q:What is alpha carbon? What is beta carbon?
The method of marking C is generally used in organic matter, and the C atom directly connected with the functional group is called alpha carbon. The C atom separated from the functional group is called C beta atom, and alpha carbon and beta carbon are not unique
