Q:Who knows the diamond is?Who knows the diamond is carbon? Is it C60?
It is also called the diamond diamond, crystal, it is not the molecules themselves, so the formula does not apply to.C said it is only by this kind of carbon elements. While C60 is footballene is another matter, the 60 is because it is a molecular crystal, each molecule consists of 60 carbon.
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 are the causes of internal cracks in continuous casting billet?
A French Research Institute of carbon, sulfur and phosphorus influence on continuous casting billet hot cracking, a total of three test groups of carbon manganese steel, carbon, sulfur and phosphorus content of each sample is different.
Q:I would like to ask what products need billet,
As for sales, one to information, two to high quality and low price, three to find relations.
Q:If the casting speed is not steady, what will happen to the billet?
The instability of the casting speed leads to the unstable surface of the mould and increases the probability of slag entrapment in the mold.
Q:Are billet metals within the metal range?
Two kinds of billets, ferrous, ferrous and metallic, belong to ferrous metal, copper and copper alloy, aluminium and aluminium alloy, and belong to colored metal
Q:Difference between medium frequency continuous casting billet and electric furnace continuous casting billet
In general, the difference between medium frequency furnace steelmaking and electric arc furnace steelmaking:1, intermediate frequency furnace slag can not, so the harmful elements such as P, S and other elements can not be removed, and the electric arc furnace can;2, if not blowing furnace carbon reduction, so C elements cannot be adjusted downward, and the arc furnace can only increase;
Q:What do you mean by adding carbon to a table tennis racket?
What a professional? I don't know what is known but with carbon carbon line take this hit the ball the more comfortable to take shape
Q:What about carbon 4 and carbon 5?
Carbon four is butane, C4H10 carbon five is pentane C5H12
Q:How to calculate the cost price of billet?
The ratio of slag to billet (63% fine powder) is about 3:1, which accounts for about 60%. of billet cost
