Q:What is carbon accumulation?
Generally refers to the polycarbonate, PC, is a kind of thermoplastic plastics, good transparency, good mechanical properties, surface hardness, common uses such as CD, plastic glasses, a fence, protective window, public places, vacuum cleaners, coffee machine, juicer barrel, refrigerator shelf, pure such as the bucket.
Q:Carbon and low alloy steel billet has specific uses difference between them and what is the difference?
Primeton Pu board generally refers to A3; carbon steel refers to the high quality carbon steel, such as No. 45 steel, 35 steel and so on; that in addition to the carbon and other elements, such as Cr, Mo etc., in which the carbon ratio below 30 for low alloy steel
Q:Use medium frequency furnace (1 million 500 thousand volt ampere) to produce 1 ton cast steel blank, how much kilowatt hour is consumed?
Look at the quality of scrap and the operation of workers, power consumption is generally between 550~650.
Q:How to purchase suitable billet heating furnace
Choice can not be blind, you can not just look at the price, the choice of advice you consult more manufacturers, and then use the exclusion method to determine your final goal. Online can take a look at live video, more reference.
Q:How do steel billets come out?
Two, pig iron and scrap steel1, smelting equipmentA, BOF: top and bottom blowing, blowing, now is widely used in pure oxygen top blown converterB, open hearth:C, electric steelmaking:
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:Fish pole carbon cloth tcf. Vcf. Svf. Hcf. On behalf of what?
According to the T value difference, broadly divided into 4 categoriesHCF: for 24T advanced carbon fiber materialSCF: for 30T advanced carbon fiber materialVCF: for 40T~50T premium carbon fiber materialTCF: for 55T~80T top carbon fiber materialHVF, HCF means high carbon fiber, H High (Senior).HVF:High, Volume, Fiber carbon fiber material 30T-40T.HCF:High, Volume, Carbon, Fiber carbon fiber material 24T."SVF" and "SCF" mean "super high carbon fiber", and "H" means "Super"SVF:Super, High, Volume, Carbon, Fiber carbon fiber material 40T-60T.SCF:Super, Volume, Carbon, Fiber carbon fiber material 30T.
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.
Q:What is the active carbon. What is the difference with the charcoal?
The chemical activation method. The activator of discharged gas, or by activating agent impregnated material, after the high temperature treatment can be activated carbon. The activated carbon has a microcrystalline structure, crystallite alignment completely irregular. The micro crystal (radius of less than 20, a: = 10-10 m), transition hole (radius 20 ~ 1000), big hole (radius of 1000 ~ 100000), so it has great inner surface, the surface area of 500 to 1700 meters / 2 grams.
Q:The reason for the blowhole in the billet to be pulled out by the continuous casting machine is 100
1: new furnace, new furnace lining contains more gas2: raw material no clean, no coincidence?3: melt protection? Temperature is not high, no refining and static?4:3 point, mold and traction to look for defects, mold cooling effect - water temperature - traction line and horizontal - traction process5: stop and pull
