Silicon Control In Blast Furnace

. Although the wide variation in input variables were known unless the diminutive reason was difficult to identify due to complexities in thrive Furnace Process. Hence a Six Sigma Black tap render had been taken up to control the silicon level of BF # 1 savory alloy and Silicon Control in scoot Furnace Hot Metal is one of the most exact problems in todays agitate Making. With deterioration in character reference of iron ore day by day, silica accuse in the burden material has a steady increase. The aforesaid(prenominal) story is with the reversal ash, which passes good amount of silicon in the hot admixture. all 0.1% diminution in silicon in the hot admixture gives rise to 1.5 % increase in hot admixture production. In the competitive scenario of todays Iron Making and so it is necessary to reduce every spotlight of Silicon in hot metal to boost up furnace production and productivity. sustain of Blast Furnace Operation keys 0.5 to 0.7 % Silicon in hot metal i s the optimum for furnace productivity and furnace health. Blast Furnace # 1 in Bhilai mark Plant, India had a typical problem of producing graduate(prenominal) silicon metal since July 2005. other(a) resembling 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 epitome and Graphical Summary of diachronic Data helped to find come on a baseline of 64.88 % casts having silicon in hot metal more than 0.7% and an entitlement of 33% casts on daily average selective information base. A ta rget of reduction of 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 critical inputs after C&E Matrix and FMEA. lapsing Analysis was done on real time info and best-fitted line were plotted to find out the effects of those critical inputs on hot metal silicon. Finally a regression Equation was found and ladder values of the inputs have been obstinate from Confidence Band (95 %) of fitted...If you fatality to get a integral essay, order it on our website: OrderCustomPaper.com
