| Abstract: | Bayi Steel utilized steelmaking sludge for lime hydration and supplement water of rotary mixer instead of clear water in sintering production.Aiming at existent technological problems such as sludge pipe clogging,sludge pump failure,unstable flow and the rotary mixer adhered sludge,a series of measures were taken：controlling the sludge concentration,improving the disposal of sludge pipelines and structural design of rotary mixer spray-water,adopting vertical submerged pump and rising the automation level of the equipment etc.Then the wet sludge was directly used by 212 thousand tons every year above,saving fresh water consumption for 169.6 thousand tons per year and annual direct economic benefit exceeded 19 million Yuan. |
