Technical field
The present invention relates to a kind of producing cement short flow-process with metallurgical furnace slag system and method, this system and method can carry out the superfine powder processing to slag or non-ferrous slag, and metallic particles is separated with non-metallic particle.The flow process of this system is lacked, is not exploded, safety, environmental protection, can realize the real online direct processing of metallurgical slag and through magnetic separation or jigging screening after cement is processed in extra-fine grinding, realize that the metallurgical slag handling rate reaches 100%.
Background technology
The metallurgical industry of countries in the world, 1 ton of crude steel of every production all can discharge slag, 300kg iron content granulated slag and other waste materials of about 130kg.Hundred million tons of the about 1-1.5 of the whole world annual discharging slag amount.It is existing more than 100,000,000 tons that China accumulates slag, and slag steel content about 10% promptly has 1,000 ten thousand tons of steel to be deposited in the waste residue, and annually still increase progressively with nearly ten million ton bed drain purge, and the utilization rate of slag is lower, is about 10%.Traditional slag treatment process is hot application or hot vexed method (Baosteel, Shoudu Iron and Steel Co and Anshan iron and steel plant adopt this method), promptly liquid steel slag is poured into vexed slag ladle, fetch water the cooling after again secondary have bad luck to the slag mountain, fragmentation is sorting again, its shortcoming is that technology is long, expense is high, land occupation, contaminated environment, cause the waste of resource, influences the sustainable development of steel and iron industry.Therefore, be necessary slag is carried out the research of minimizing, resource and high value comprehensive utilization.
Slag is exactly the slag of discharging in the steelmaking process.Slag mainly is the impurity brought into of the oxidized back of each element generates in the metal charge oxide, the gainster that is etched and fettling material, metal charge and for adjusting slag making materialses such as lime stone that slag character specially adds, dolomite, iron ore, silica.Carry some abrasive grits in the slag secretly, hardness is big, the main chemical compositions of slag (mass fraction/%) have: CaO, SiO
2, Al
2O
3, Fe
2O
3, MgO, P
2O
5, fCaO; What have also contains V
2O
3, TiO
2Deng, composition has fluctuation in a big way.The characteristics of slag are that the oxide of Fe is with FeO and Fe
2O
3Form exists; And based on FeO, total amount is below 25%.
Contain dicalcium silicate similar (C2S) and tricalcium silicate (C3S) in the slag to Portland clinker, the mass fraction of the two is more than 50% in the high basicity converter slag, in, in the slag of low basicity the two mass fraction below 50%, in, be mainly dicalcium silicate (C2S) in the slag of low basicity.The generation temperature of slag is more than 1560 ℃, and the firing temperature of Portland clinker is about 1400 ℃.The generation temperature height of slag, compact crystallization, crystal grain is bigger, and hydration rate is slow.Therefore slag can be called the burning Portland clinker.
This shows, slag not only is not a discarded object, and be extraordinary cement raw material, particularly utilize its low hydration heat, microdilatancy characteristic to produce and be applicable to big scale of construction waterproof, leakage-preventing concrete works cement, as build a dam and big scale of construction buried concrete engineering, can realize " zero " discharging of slag fully.
The processing mode that many kinds of metallurgical cinders are arranged in prior art, Fig. 1 has shown that the slag in the prior art transports the layout schematic diagram, and in the figure, the left side of steel stove 1 is a steel ladle 2, the right side of steel stove is a receiver 3, and steel ladle and receiver back and forth move along straight line track 4 respectively.Common way is earlier slag to be imported receiver, and receiver sails out of and with crane gear receiver is transported to the granulating device place behind the steel stove and carries out granulated processed.Chinese patent 02135756 discloses a kind of tilting type steel slag water quenching treatment method; it is provided with water quenching pool; cylinder is installed in the water quenching pool edge; in cylinder one side pelletizer is installed; after molten steel slag is poured in the slag ladle on the slag ladle and carriage; be transported to cooperating of hanger on the suspension hook of water quenching pool place by hoist engine and the slag ladle; slag ladle is tilted; the leading arm of tumbling after turning to certain angle on the slag ladle falls within on the cylinder; making slag ladle is that the center rotates the slag of slowly tumbling in water quenching pool with the rotating shaft of cylinder again; the pressure water of pelletizer has sprayed the formation water curtain simultaneously; make slag enter granulation behind the water curtain; enter then in the water quenching pool, the slag after shrend is seated in to be deposited the slag field and gets final product.The method of this patent belongs to the processed offline method, the long flow path of this method, and only slag is processed into grain slag, and do not finish " zero " discharging that realizes slag, therefore, need to propose a kind of producing cement short flow-process with metallurgical furnace slag system and method.
