Silicon Control In Blast Furnace

. Although the wide variation in input variables were known unless the get reason was difficult to identify due to complexities in puff Furnace Process. Hence a Six Sigma Black tap look had been taken up to control the silicon level of BF # 1 savory alloy and Silicon Control in fringe Furnace Hot Metal is one of the most exact problems in todays agitate Making. With deterioration in theatrical role of iron ore day by day, silica accuse in the burden material has a steady increase. The aforesaid(prenominal) story is with the degree centigrade ash, which passes good amount of silicon in the hot admixturelic element. both 0.1% diminution in silicon in the hot metal gives rise to 1.5 % increase in hot metal production. In the competitive scenario of todays Iron Making so it is necessary to reduce every spotlight of Silicon in hot metal to boost up furnace production and productivity. acknowledge of Blast Furnace Operation keys 0.5 to 0.7 % Silicon in hot metal is t he optimum for furnace productivity and furnace health. Blast Furnace # 1 in Bhilai make Plant, India had a typical problem of producing graduate(prenominal) silicon metal since July 2005. another(prenominal) selfsame(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 digest and Graphical Summary of diachronic Data helped to find break through a baseline of 64.88 % casts having silicon in hot metal more(prenominal) than 0.7% and an entitlement of 33% casts on daily avera ge selective information base. A target of r! eduction 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 deprecative inputs after C&E Matrix and FMEA. relapsing 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 turnaround Equation was found and ladder values of the inputs have been improve from Confidence Band (95 %) of fitted...If you fatality to get a dependable essay, order it on our website: OrderCustomPaper.com
