Continue Casting Steel Bloom Manufactured  by Blast Furnace After casting billet is ingot steel products.Mainly from the manufacturing process of billet can be divided into two kinds: die casting billet, slab and the die casting process has been basically eliminated


2.Main Features of  Continue Casting Steel Bloom Manufactured  by Blast Furnace.

(1) the billet: cross section width and height are equal, or the difference is not big, is mainly used to rolling profile, strip, wire screw, etc.Such as working Angle channel steel, strip steel, line 145, etc.
(2) the slab: cross section width and height of the ratio of the larger, mainly used for rolling plate.Such as hot rolled coils, cold rolled coil plate, plate, etc.

Q:Charcoal classification
Hard charcoal. By hardwood such as Fagaceae Quercus, Castanopsis trees, secondary birch and etc..Broad-leaved charcoal. Charcoal made from a mixture of hard and soft hardwood.Pine charcoal. Carbon fired from pine or other needle wood. In addition to bamboo and bamboo charcoal burning with shells, stones (coconut shell, peach stone charcoal etc.) wood raw material firing. Charcoal collected from household stoves in the cell known as carbon. If the charcoal is crushed and mixed with proper adhesive, and then pressed, formed and roasted, the deposit is made. According to the burning process of silica and carbon black.
Q:What is the billet price in China today?
In the short term is still the main shock, the domestic price rise compared to the previous 10 yuan / ton, the price is not the same in each region, so you still have to carefully check the price, from the upstream iron ore, domestic ore prices stabilize, without much change, with the real estate back to temperature.
Q:What is the HS number for billet export?
Your specification 13*13*6 or 12 meters, this is a square cross section, so 7207120000 this can not be used, your billet carbon content is 0.17 to 0.23% less than 0.25%, so we must use the following7207190000 Other Billets with carbon content less than 0.25%Export tax refund: 0%MFN country of import tariff: 2%General customs duties: 11%Export tariff rate: 0%VAT: 17%
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:Billet heating furnace billet temperature reached, steel will be adhesion
There are a lot of billet heating furnace manufacturers, not just look at the price and go blind choice, billet heating furnace selection properly, will directly affect the day after work is carried out properly, choose cost-effective equipment is the first choice for users, recommended to look at the video consultation.
Q:The form of carbon in carbon steels
The solubility of carbon content when the iron carbon alloy than in the iron when the excess carbon can be in the form of carbide iron or elemental state (graphite) in alloy, which can form a series of carbide, Fe3C (cementite, 6.69%C) is a metastable phase, it is a compound complex structure gap. Graphite is a stable phase of iron carbon alloy with simple six - party structure. Fe3C has the potential to break down into iron and graphite stable phases, but the process is extremely slow at room temperature.
Q:20 what is the difference between manganese silicon steel billet and Q235 billet?
In brief, the ingredients are different and the uses are different.20 manganese silicon steel billet for high strength steel,Q235 billet is almost the most common steel, requiring the lowest.
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:Difference between billet, slab and 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. At present, the casting process has been basically eliminated. The classification is mainly divided into two kinds: slab: large cross section, high ratio, mainly used for rolling plate. Billet: cross section width, height equal, or difference is not big, mainly used for rolling steel, wire. Use billet is steel, through processing can be used as mechanical parts, forgings, processing all kinds of steel, steel, Q345B, channel steel, wire is the role of billet. Billet is used for the production of semi-finished steel products, generally can not be used directly for society. Billet and steel are strictly divided into standard, and can not be determined by the final product of the enterprise, but should be carried out according to the uniform standard of the whole society. Usually, billet and steel is relatively easy to distinguish, but for some billets, with the same specification and the same purpose (such as rolling and steel tube), whether for other industries by use, whether through steel processing process, whether after finishing mill processing to distinguish. Continuous cast steel 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:Who knows that the steel bar is always on the one side,
The rolling process of rolling mill of hot rolling and cold rolling process for the two step: a hot rolling process: from out of billet steel plant is only semi-finished products, to the rolling mill for rolling, in order to become a qualified product.
