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:Reasons and treatment methods of billet stripping in continuous casting
even two cold regions can be uniformly cooled, due to uneven thickness of shell, caused by the inconsistent temperature, the shell shrinkage is still uneven, and also there will be the development of. Therefore, the selection of unqualified mold is the main reason causing the removal. Secondly, the cooling effect of the two cooling zone can not be ignored.
Q:Can the production of continuous casting billet be damaged by using intermediate frequency electric furnace?
If there are no other major facts of harm, it seems that there is no such mandatory legal provisions to bear criminal responsibility. Mandatory closing and fines at most.
Q:What is the approximate cost of billet to cold rolling?
The cost of billet to cold rolling is about 1000Galvanized to color coated sheet costs vary greatly, generally around 300, a high of 500
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 shape is the billet?

Q:Which is good for pure iron billet?
Shanghai Xiyuan special steel products Co., Ltd. was founded in 1997 China long-term sales of imported and domestic first-line steel industrial pure iron (iron burden, magnetic iron, electrical iron) of M6 steel, 08F steel, 91F steel and other special steel products, special specifications according to user needs production organization, reasonable price, quality optimization.
Q:The role of carbon content in steels
2., the formation of carbide structure, can improve the hardness and wear resistance of steel, such as cementite, or Fe3C, that is, carbide organizationTherefore, the higher the carbon content in carbon steel, the higher the strength and hardness of the steel, but the plasticity and toughness will also be reduced. On the contrary, the lower the carbon content, the higher the plasticity and toughness of the steel, and its strength and hardness will also decrease
Q:What does the billet of the steel plant refer to?
The steel billet is the continuous casting machine by smelting steel plant casting into the blank, in the middle of products before entering the rolling process, the section size will be decided by rolling steel. When rolling the long material, the square billet is poured, the rolled plate is cast, the rolling pipe is cast into round billet, and the rolled narrow strip steel is poured into the rectangular billet, etc..
Q:How can carbon and carbon in a fishing rod be distinguished?
When it comes to the differentiation of carbon fishing rods, first of all, what are the different kinds of fishing rods containing carbon?!Carbon rod is now sold in the market are divided into three kinds, namely: carbon, pure carbon, high carbon. These three categories.1, carbon packaging, as its name implies, two layers of material, the outside layer is carbon cloth, the inside layer is glass fiber, epoxy cloth. The price of this kind of rod is lower, because it is not necessary to buy a brand because of the lower price. With a few times you can change, for beginners.2, pure carbon refers to the overall use of 30T below carbon cloth fishing rod, general 24T, 30T based, carbon content of more than 98%. Moderate price.3, high carbon refers to the overall use of more than 30T carbon cloth fishing rod, but not the whole fishing rod is made of a carbon cloth. The tonality of a fishing rod is actually modulated by a different modulus of carbon cloth.Some fishing overall with the 30T following carbon cloth, just use a very small amount of 40T or 46T carbon cloth, called high carbon rod, is actually confuse the public practice of fishing by weighing, hand identification, high carbon rod with real light, hard, two rods in a play, a ratio is obvious.
Q:What is billet?
Steel billet is a product made by steel-making furnace by casting.The billet can be divided into two kinds from the manufacturing process, mould blank and continuous casting billet.
