Q:20 what is the difference between manganese silicon steel billet and Q235 billet?
20 manganese silicon steel billet for high strength steel,Q235 billet is almost the most common steel, requiring the lowest.
Q:What does "billet" mean?
Steelmaking and continuous casting of steel products are mainly used for steel rolling, such as round bar, wire rod, sheet metal and so on
Q:What is the difference between continuous casting billet and cast billet?
Mainly to see the process, general casting efficiency is low, but the quality is acceptable, with low level (open casting billet) has great advantages in surface quality;
Q:What shape is the billet?
Material standardThickness range: 150-240mm +/-5mm, width range: 880-1530mm +/-20mmLength range: 3700-10000mm +/-500mmCross section size: 64*64; 82*82; 98*98; 124*124; 152*170mm; 120*150; 152*164;Length: 9000mmSection tolerance: square billet: +1.0/-2.0----+3.0/-1.0mm slab: width: +/-2.0MM thickness: +/-3.0MMLength tolerance: +/-200MMDiagonal tolerance of section: 3.5-8.0MMBillet cross section dimension requirements: <1242MM, not allowed; =1242MM, <=2MM, >1242MM, <=3MMBreaking (shear) expansion deformation: <1242MM square billet: no control; slab: <=15MMSurface inclination: no more than 0.1 of the bloomBending length: not more than 10MM per 1MTwist: length <=5M, <=11. Length <=7.5M, <=5.Material 3SP/PS, chemical composition,%:C, Mn, Si, S, P
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 Alfa carbon? What is beta carbon?
Alfa is directly connected with the functional groups of carbon atoms of carbon atoms, such as CH3CH2COOH CH2 in which methylene propionate is Alfa carbon carbon carbon atom is the beta carbon atom is directly connected with the functional groups and the connection of the carbon (around Kazakhstan), such as the CH3CH2COOH CH3 propionic acid methyl carbon is the beta carbon
Q:How many tons of billets does it take to produce a ton of thread steel?
The yield was increased, consumption will be reduced.
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
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 does the billet of the steel plant refer to?And steel what is the difference?
The main deformation of reinforced by ribs, binding capacity larger and concrete, so it can better withstand external force. Steel is widely used in all kinds of building structure, especially for large, heavy, light and thin wall structure of high-rise building.
