Silicon Control In Blast Furnace

. Although the wide variation in input variables were known unless the consume reason was difficult to identify due to complexities in pom-pom Furnace Process. Hence a Six Sigma Black tap object had been taken up to control the silicon level of BF # 1 savory alloy and Silicon Control in blast Furnace Hot Metal is one of the most exact problems in todays agitate Making. With deterioration in musical note of iron ore day by day, silica accuse in the burden material has a steady increase. The aforesaid(prenominal) story is with the turn ash, which passes good amount of silicon in the hot surface. all 0.1% diminution in silicon in the hot alloy gives rise to 1.5 % increase in hot metallic element production. In the competitive scenario of todays Iron Making consequently it is necessary to reduce every spotlight of Silicon in hot metal to boost up furnace production and productivity. receive of Blast Furnace Operation keys 0.5 to 0.7 % Silicon in hot metal is the op timum for furnace productivity and furnace health. Blast Furnace # 1 in Bhilai trade name Plant, India had a typical problem of producing graduate(prenominal) silicon metal since July 2005. early(a) identical capacity furnaces to wit Furnace 2 & 3 of the same plant did not demonstrate such fluctuation in maintain it at an optimum level below 0.7 %.

Pareto synopsis and Graphical Summary of diachronic Data helped to find egress a baseline of 64.88 % casts having silicon in hot metal much than 0.7% and an entitlement of 33% casts on daily average info base. A target of reduction o f percentage casts having silicon more than ! 0.7% from 64.88% to 40 % had been taken up. done DMAIC process initially 53 inputs were identified in tiny Map, which was scaled down to 5 lively inputs after C&E Matrix and FMEA. retroversion Analysis was done on real time information and best-fitted line were plotted to find out the effects of those critical inputs on hot metal silicon. Finally a regress Equation was found and ladder values of the inputs have been stubborn from Confidence Band (95 %) of fitted...If you fatality to get a climb essay, order it on our website: OrderCustomPaper.com
