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 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,
The main mold manufacturers, equipment manufacturers, military departments, measuring and cutting tools manufacturers.As for sales, one to information, two to high quality and low price, three to find relations.
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?
Mainly from the shape of two:Slab: the ratio of section width and height is larger, which is mainly used for rolling plate.Billet: cross section width, height equal, or difference is not big, mainly used for rolling steel, wire.Texture of materialContinuous casting square and rectangular billets are mainly made of plain carbon steel, low carbon and low silicon cold rolled material, high quality carbon structural steel, low alloy high strength steel, special steel and so on.
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 is the drop per minute of the billet temperature at 850?
Cold rolling is not considered. The initial rolling temperature (surface) of the billet is generally 1000-1150 degrees.
Q:Difference between billet, slab and billet
Production process of billet is through three methods: one is through the production of steelmaking and continuous casting equipment system, the molten steel is directly cast into the billet; two of steelmaking production systems of steel ingot or billet by rolling system of steel rolling equipment processing semi-finished products; three is the production of steelmaking system by forging semi-finished steel ingot the processing equipment. Market trends 1, domestic crude steel production remains high, although the domestic steel market has been relatively sluggish in recent times, and steel losses are more, but this does not seem to affect the enthusiasm of steel production. According to the China Steel Association statistics show that: in early April, the daily output of crude steel in key enterprises in China was 1 million 697 thousand and 300 tons, and the average daily output of crude steel in China was estimated at 2 million 123 thousand and 900 tons. And in mid April, crude steel daily output of ten days, although there has been a drop back, but still at a high level. According to statistics, in mid April, the average daily output of crude steel in key enterprises nationwide was 1 million 689 thousand and 100 tons, and the average daily output of crude steel in China was estimated at 2 million 115 thousand and 800 tons. Such a large production and sluggish demand in stark contrast, which is a drag on steel prices down one of the important factors.
Q:What is alpha carbon? What is beta carbon?
The C atom separated from the functional group is called C beta atom, and alpha carbon and beta carbon are not unique
