Inside the 5 limits with 5-8% 2) operation leaving residue. Add a capacity to reduce early days lime and dolomite, can be in CaO, MgO is withheld to exist in broken bits eventually; In addition, feO is withheld in broken bits eventually, enlarge the tendency that liquid state broken bits fastens. 3) smelt process is used low - tall - tall - low, 4 paragraphs of guns law. Early days low gun, form slag bath quickly; After early days broken bits is fused raise a gun in time, form normaller gun of tall 200-400mm soft blow, increase amount of the FeO in broken bits, furnace condition joins makings of metaphase broken bits below sufficient and active circumstance; Terminus should be in ensure to the gun is pressed below the condition of broken bits fluidity eventually. 4) transform oxygen gun shower nozzle, increase oxygen gun aperture to count in order to increase aerobic efflux, increase bath agitate, make career in order to raise the FeO in broken bits, suit smelt of low ferrosilicon water. Domestic Han steel 3 steelworkses, after taking above step, got clear result, oxygen gun life by 2006 6, the 73 furnace July rise 9, the 115 furnace October, when smelt of low ferrosilicon water, average time of processing of gun of every furnace oxygen decreased 3 minutes, it is good that at the same time smelt process changes broken bits, furnace condition is stable.
