Q:How are the billets classified?
Billet classification of GB, it is convenient to check
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:Reasons and treatment methods of billet stripping in continuous casting
The main reason for the stripping is that the slab is not uniformly cooled in the mold, which results in uneven thickness of the shell, which results in uneven shrinkage, which leads to the unevenness of the billet. If the mould outlet, two cold area is uneven, the shell support is not full, it will make breaking-off intensified;
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. The test according to the process of the sample for cooling, in order to study the effects of the three elements of the internal crack of continuous casting billet hot.
Q:What is the approximate cost of billet to cold rolling?
The cost of billet to cold rolling is about 1000Galvanized to color coated sheet costs vary greatly, generally around 300, a high of 500
Q:Fish pole carbon cloth tcf. Vcf. Svf. Hcf. On behalf of what?
Carbon cloth classification, a semicolon after the term, usually called HVF and SVF, where SVF is divided into VCF and so on! The index of carbon fiber is T (ton), common carbon part is 20T-30T commonly. HVF is 30T-40T, SVF is 40T-60T. SVF lighter than HVF, higher strength, better elasticity of the material of products: Di 46T SVF meaning 60T ultra high strength and high modulus carbon fiber cloth, HVF carbon fiber reinforced 30T 40T strength and high modulus. But the 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:Use medium frequency furnace (1 million 500 thousand volt ampere) to produce 1 ton cast steel blank, how much kilowatt hour is consumed?
This depends on the intermediate frequency furnace voltage level and inverter efficiency, the general high voltage will save power, generally 550-700 range, details can refer to wcdlsb.net site medium frequency furnace data
Q:What about carbon 4 and carbon 5?
Carbon four is butane, C4H10 carbon five is pentane C5H12
Q:What is alpha carbon? What is beta carbon?
The method of marking C is generally used in organic matter, and the C atom directly connected with the functional group is called alpha carbon. The C atom separated from the functional group is called C beta atom, and alpha carbon and beta carbon are not unique
