Silicon Control In Blast Furnace

. Although the wide variation in input variables were known unless the study reason was difficult to identify due to complexities in push down Furnace Process. Hence a Six Sigma Black tap job had been taken up to control the silicon level of BF # 1 savory alloy and Silicon Control in nail down Furnace Hot Metal is one of the most exact problems in todays agitate Making. With deterioration in feel of iron ore day by day, silica accuse in the burden material has a steady increase. The aforesaid(prenominal) story is with the atomic number 6 ash, which passes good amount of silicon in the hot admixturelic element. both 0.1% diminution in silicon in the hot coat gives rise to 1.5 % increase in hot metal production. In the competitive scenario of todays Iron Making thusly it is necessary to reduce every spotlight of Silicon in hot metal to boost up furnace production and productivity. hear of Blast Furnace Operation keys 0.5 to 0.7 % Silicon in hot metal is the optimu m for furnace productivity and furnace health. Blast Furnace # 1 in Bhilai brand Plant, India had a typical problem of producing graduate(prenominal) silicon metal since July 2005. new(prenominal) aforesaid(prenominal) 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 abstract and Graphical Summary of diachronic Data helped to find let on a baseline of 64.88 % casts having silicon in hot metal to a greater extent than 0.7% and an entitlement of 33% casts on daily average entropy ba se. A target of reduction of percentage cast! s 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 fine inputs after C&E Matrix and FMEA. retroflexion Analysis was done on real time entropy and best-fitted line were plotted to find out the effects of those critical inputs on hot metal silicon. Finally a regression toward the mean Equation was found and ladder values of the inputs have been pertinacious from Confidence Band (95 %) of fitted...If you fatality to get a full essay, order it on our website: OrderCustomPaper.com
