The flux that uses in agglomeration mine production has: Burn dolomite lime of limestone, calx, disappear, dolomite, gently, serpentine. Total to them demand is active ingredient tall, harmful foreign matter is little, size is proper.
(1) limestone is production spends the flux with agglomeration commonly used mine from fusibility and Gao Jian, should choose SiO2 +Al203 content low, be decomposed to make it is in agglomeration process and complete mineralization, good its broken to 1? Between 3mm.
(2) calx and disappear lime. Partial calx is used in production or disappear lime replaces limestone with aggrandizement agglomeration process, be in especially fine when grinding concentrate pink agglomeration, add a person 4% right-and-left calx can raise crop 30%~35% . The gel body grain that digests Ca(OH)2 in compound because of calx, increase the performance becoming a ball of compound, also increase the wet size of compound, make compound maintains better permeability in agglomeration process. Active should be used in production the big, calx that burns nevertheless, granuality should be less than 5mm.
Some factories aborning replaces calx with disappear lime, the Yang Chen when deserving in order to solve calx to add and calx are bibulous digest cause compound water to divide difficult control to wait for a problem. But should have controlled when use disappear lime hydrous buy and had solved agglomerate problem. Is the moisture control of general disappear lime in 15% ? 20% .
(3) dolomite and burn dolomite gently. Dolomite adds the MgO content that person compound is mine of agglomeration of adjustment of in order to, the MgO content that a requirement achieves in order to assure blast furnace in manufacturing slag. But Bai Wushi is very difficult broken, in be being produced so useful burn dolomite gently to hit those who replace dolomite.
(4) serpentine (2H2O) of · of 3MgO · 2SiO2 is sufficient a kind of Gao Mei, Gao Gui, low calcic flux, content of MgO of Piao of mine of the agglomeration that move regret is used when agglomeration of pink of rich ore of high grade low SiO2, for example steel of our country treasure and Japanese steel ironworks deserve to add 3% right-and-left serpentine in agglomeration compound the manufacturer of agglomeration of pink of concentrate of our country magnetism, because compound Piao content is high, do not use serpentine so, and use dolomite or burn dolomite gently. The serpentine that Bao Gang uses contains MgO 37.94% , SiO2 37.81% , granuality control is controlled in 1.5mm.
Magnesian olivine is used extensively in Europe (2MgOSiO2) .
