in oxygen converter steel industry, why dont we put MgO and CaO directly in it, not in form of dolomite ?
There is too many people who depend on pensions from the Big Three when you get a pension from the Big Three after 30 years of service I think they government should try to make good this obligation If not prepare for a fall of the economy not seen since 1929 I have heard a lot of young people pooh pooh this idea Well you may get a chance to see a real Depression in 2009 just 80 years since the last big depression Also there is a plague comingand the last plague was in 1918 Hope for the best but prepare for the worst.
Tidyest way is to use a pipe bender. Easiest is to use double elbows at each end. Jim www.airpowered .uk
I would use a Tee for the top pipe and a 90 degree elbow on the bottom and run them together.
Dolomite is an abundantly naturally occurring mixed MgCO3/CaCO3 raw material. It is cheap and easily mined. There is no point in trying to find a pure source of calium carbonate to produce lime. From my reading of the process: Fluxes (burnt lime or dolomite) are fed into the vessel to form slag, which absorbs impurities of the steelmaking process. During blowing the metal in the vessel forms an emulsion with the slag, facilitating the refining process. It appears that CaO alone would suffice, but CaO/MgO mixture is used because of the availability and cheap cost of the dolomite.
