5.FAQ of  Continue Casting Steel Bloom Manufactured  by Blasting Furnace

 

We have organized several common questions for our clientsmay help you sincerely 

 

①What kinds of the spec. of steel billet suitable to produce the section steel?

It is shade blank steel billet is better.

 

②Could we check the process of the producing in the steel mill?

Sure, but you must follow the instruction of the steel mills during the visiting. For safety consideration.

 

③How many days we should order before producing?

It depands on the detail order and situation of the steel mill, usually it is earlier, it is better.

Q:Use medium frequency furnace (1 million 500 thousand volt ampere) to produce 1 ton cast steel blank, how much kilowatt hour is consumed?
This depends on the intermediate frequency furnace voltage level and inverter efficiency, the general high voltage will save power, generally 550-700 range, details can refer to wcdlsb.net site medium frequency furnace data
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:How can carbon and carbon in a fishing rod be distinguished?
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: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:The form of carbon in carbon steels
In solid solution, it is in the interstitial space of lattice, resulting in lattice distortion. The solubility of carbon in gamma -Fe is maximal, but not more than 2.11%; the solubility of carbon in alpha -Fe is not more than 0.0218%; and in Delta 6-Fe, no more than 0.09%.
Q:How do steel billets come out?
I. mining1, iron ore2 limestone mine3, coal mineTwo 、 burden preparation1. Iron ore sintering2 coking coal cokingThree, iron: in the blast furnace, sintering iron ore, limestone, coke, iron ore in the iron elements reduced to metal iron, then the product is pig iron.
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: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: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. The test according to the process of the sample for cooling, in order to study the effects of the three elements of the internal crack of continuous casting billet hot.
Q:Who knows that the steel bar is always on the one side,
Billet sent from the steelmaking plant, first into the furnace, then after rolling mill rolling
