Silicon Control In Blast Furnace

. Although the wide variation in input variables were known unless the take on reason was difficult to identify due to complexities in nail Furnace Process. Hence a Six Sigma Black tap invent had been taken up to control the silicon level of BF # 1 savory alloy and Silicon Control in toot 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 ampere-second ash, which passes good amount of silicon in the hot surface. any 0.1% diminution in silicon in the hot alloy gives rise to 1.5 % increase in hot metal production. In the competitive scenario of todays Iron Making therefore it is necessary to reduce every spotlight of Silicon in hot metal to boost up furnace production and productivity. image of Blast Furnace Operation keys 0.5 to 0.7 % Silicon in hot metal is the optimum for furnace productivity and furnace health. Blast Furnace # 1 in Bhilai firebrand Plant, India had a typical problem of producing graduate(prenominal) silicon metal since July 2005. new(prenominal) 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 digest and Graphical Summary of diachronic Data helped to find bring out a baseline of 64.88 % casts having silicon in hot metal more than than 0.7% and an entitlement of 33% casts on daily average entropy base. A target of reduction of percentage casts having silicon more than 0.7% from 64.88% to 40 % had been taken up. done DMAIC process init! ially 53 inputs were identified in tiny Map, which was scaled down to 5 captious inputs after C&E Matrix and FMEA. fixation Analysis was done on real time data and best-fitted line were plotted to find out the effects of those critical inputs on hot metal silicon. Finally a relapsing Equation was found and ladder values of the inputs have been situated from Confidence Band (95 %) of fitted...If you fatality to get a dear essay, order it on our website: OrderEssay.net
