Q:What are the common defects in billet? What's the cause?
Five, X ray inspection, porosity, ultrasonic testing:One, 5, magnetic particle inspection, the back of the dent; 6, overheating and over burning: 1, penetrant inspection;Four. 2. The size of the weld does not meet the requirements and slag inclusion; 3 high-energy X-ray inspection, lamellar tearing and R ray flaw detection; 2;Five;Two: 1, arc crater;Methods for inspection of weld defects;
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:Continuous casting billet has slag inclusion and air hole
1. Whether the injection hole before the casting is replaced with the protective slag instead of the special drainage sand, and whether the drain sand is dry or not2, whether it is too early to start adding protective slag is to protect the slag whether it is dry or not3, the opening of the mold to maintain the steel surface uniform and stable, rising to the required height, the key is fluctuation.
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: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?
My understanding is that..:Billet: Billet, refers to the casting of roughSquare steel: Square, Bar, the product is rolled on the basis of square billet.
Q:What shape is the 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.classification
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: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..
