Steel Billet Produced by Big Blast Furnace

 

1.Structure of  Steel Billet Produced by Big Blast Furnace

Steel Billet Produced by Big Blast Furnace  Billet section of square, round, flat, rectangular and abnormity, etc Several, mainly related to shape of rolled products. Simple rolled section steel, choose cross section of square billet or rectangular billet. rolling The sector products such as flat steel, Angle steel, select the rectangular billet or slab. Had better profiled billet when production beams, channels, and in rolling process Lines and improve the yield. The raw material of round billet is the production of seamless tube. 


2.Main Features of Steel Billet Produced by Big Blast Furnace

Steel Billet Manufactured by Blast Furnace without Boron section size should meet the requirements of rolling deformation and finished product quality, but also roll strength and biting condition of restrictions. General steel Billet section height H. And the roll diameter D The ratio of the ( namely H/D) Should be less than or equal to zero 0.5 . Length of steel billet by finishing temperature, Rolling time and the length of the product Or times ruler. When heated too long accident prone to bump the furnace wall of steel, too short, furnace bottom utilization rate is not high, influence the heating furnace production. For the production Choose a variety of steel and steel billet, should consider the affinities of billet, as far as possible in order to improve the productivity of the roughing mill, simplify the stock management of workshop.

4.  Steel Billet Produced by Big Blast Furnace Specification

Steel Billet Manufactured by Blast Furnace without Boron rolled steel, after processing can be used for mechanical parts, forging parts, processing all kinds of steel, steel Q345B channel steel, wire rod is the role of the billet. Steel billet is used in the production of semi-finished products, generally cannot be used directly for the society. Steel billets and steel are strictly divided into standard, cannot decide to whether the business enterprise of the final product, and according to unified standards to perform the whole society. Typically, billet and the steel is relatively easy to distinguish, but for some steel billet, and have the same specification and same steel purposes (such as rolling tube billet), whether can be used for other industries, whether through steel processing process, whether through a finished product rolling mill processing to distinguish

 

The classification of the Bloom Mainly from the shape is divided into two kinds: Slab: cross section width and height of the ratio of the larger, mainly used for rolling plate. Bloom: equal cross section width and height, or a huge difference, mainly used for rolling steel, wire rod.

Bloom material standard The thickness range: 150-240 - mm + / - 5 mm The width of the range: 880-1530 - mm + / - 20 mm Length range: 3700-10000 - mm + / - 500 - mm Cross-sectional size: 64 * 64 ; 82 * 82 ; 98 * 98 ; 124 * 124 ; 120 * 150 ; 152 * 164 ; 152 * 170 mm Length: 9000 mm The section of tolerance: Bloom: 1.0 + / - 2.0-1.0 + / - 1.0 mm The slab width: + / - 2.0 MM ; Thickness: + / - 3.0 MM

Q:Fish pole carbon cloth tcf. Vcf. Svf. Hcf. On behalf of what?
CF: is the abbreviation of Carbon Fiber in English, which means carbon fiber in ChineseCarbon fiber index for T (ton), ordinary carbon cloth is generally 20T-30T.Domestic ordinary carbon fishing rod material is generally 24T carbon fiber cloth. The higher the T value, the higher the strength and elasticity of the material.
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 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:Which is good for pure iron billet?
If you would like to consult more detailed information, I suggest you choose Shanghai far west special steel products Co., ltd..
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: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 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?
That depends on what kind of material you are producing steel billet, and are generally the city's iron ore came.
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..
