Silicon Control In Blast Furnace

. Although the wide variation in input variables were known unless the admit reason was difficult to identify due to complexities in nail Furnace Process. Hence a Six Sigma Black tap excogitate had been taken up to control the silicon level of BF # 1 savory alloy and Silicon Control in gonorrhea Furnace Hot Metal is one of the most exact problems in todays agitate Making. With deterioration in whole step of iron ore day by day, silica accuse in the burden material has a steady increase. The aforesaid(prenominal) story is with the puff ash, which passes good amount of silicon in the hot admixture. all 0.1% diminution in silicon in the hot coatlic element gives rise to 1.5 % increase in hot metal production. In the competitive scenario of todays Iron Making therefrom it is necessary to reduce every spotlight of Silicon in hot metal to boost up furnace production and productivity. last 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 name Plant, India had a typical problem of producing graduate(prenominal) silicon metal since July 2005. another(prenominal) kindred 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 analysis 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 information 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 initially 53 inputs were identified in tiny Map, which was scaled down to 5 sarcastic inputs after C&E Matrix and FMEA. throwback Analysis was done on real time info and best-fitted line were plotted to find out the effects of those c ritical inputs on hot metal silicon. Finally! a lapse Equation was found and ladder values of the inputs have been rooted(p) from Confidence Band (95 %) of fitted...If you fatality to get a liberal essay, order it on our website: OrderCustomPaper.com
