| Cupola hot metal production of diesel engines with vermicular iron exhaust pipe
For temperatures up to 600 ~ 800E. At high temperatures,ugg prezzo, gray cast iron exhaust pipe will be left open, will be deformation of ductile iron exhaust pipe, and compacted graphite cast iron vent pipe above the flaw without Blake To this end, we conducted a cupola hot metal production of vermicular iron exhaust pipe experiment. 1 production conditions and experimental methods: the furnace was brought before the furnace 5t / h cupola. Hot metal with the original cast iron (wt%): 368 ~ 3.89C1.0 ~ 1.4Si, O. 4 ~ 06Mn''0 .03. And O. O5 ~. With a portable direct reading double platinum into the hot guy - even electric -0 0 O measured 7P draw the iron slot. S water temperature of 08 Fe 1390 ~ 1450 ~ Z. Containing rare earth and magnesium vermicularizing loaded within the ladle at the end of the pit,Moncler online, a play out of hot metal: Wangchu iron water tank slowly sprinkle the iron tablets were 75FeSi until the outbreak of smooth, the use of cryolite or modified pearl powder rock particles skimming; spoon to take iron triangle specimen Front irrigated, while the thinner 75FeSi block added to the surface of the floating bag of hot metal silicon birth. Specimen fracture was reduced moderately concave silver, crisp percussion sounds that creep issued to the successful test rod casting and casting. Test bar size rill / l: ∞ 0 × 340, with Taiwan fat Note the end of dry sand. Pengshang cut from the metallurgical test specimens, according to JB3829 - 84 assessment. And chemical composition analysis. 2 experimental results. 2.1RE Huan Wei and the impact of Mg when the cast iron 0.01% i. 4fRE most +3.3 (S won a raft s W%. While adding RE and Mg,ugg stivali, the RE may be low (Table 2). Table 2 ± elements and rare addition of magnesium (%) 3.2 birth to rare earth the main elements obtained is easy to produce compacted graphite cast iron carbide,stivali ugg, so high and mighty need to strengthen breeding. floating extension of the inoculation effect of silicon has nurtured the role, to improve the creep effect of the rate and significantly reduce carbon (Table 3). because the large floating 75FeSi the hot metal surface gradually melting, molten silicon from top to bottom within the brigade level decreases, there is rich surface layer of silicon concentration and temperature fluctuations over a large hair floating in Table 3 triangular silicon bred specimens of the blast furnace number of groups of optical phase barrier organization of the state creep rate (%) pearl pieces (%) phosphide (%) l stone roller of the bad (%) the amount of floating silicon forged before 1550 after the 95200.5l {45 floating silicon micro processing 3.3 to handle too far will creep be the ball of a good hot metal, hot metal at this time can be supplemented with the original residual Mg and RE in order to reduce cancer and improve the rate of creep. If additional hot metal to handle the hot metal can not obtain a higher rate of creep, this time to Park interference plus trace elements such as graphite spheres of the other. 3.4 deal less than if the population was found in the dark triangular piece of black test, two patients without depression, the sound muffled, fracture neat, that treatment is not successful this time creep, can write Java additional vermicularizing, stirring hot metal to melt,moncler günstig, add coil treatment or subcontract plus ball of molten iron or Park. · s3 · 相关的主题文章： ed hardy Summit 2006 Shanghai Aluminum - aluminum ugg prezzo Kenya mining titanium _2988 jordan shoes Developed by Japan International Mach |
