Description
Technical field
The present invention relates to a kind ofly, especially utilize nickel smelting waste slag to produce the method for artificial high-grad iron ore deposit by new sintering process with the get rich method of iron ore of nickel smelting waste slag production ironmaking personnel selection.
Background technology
Nickel smelting waste slag is a kind of solid slag of discharging during the Metal smelting of non-ferrous metallurgical enterprise nickel is produced, a kind of iron and steel resource of uniqueness especially.Not only contain a large amount of ferrous metal (about 34%-45%), silicon-dioxide, calcium oxide, magnesium oxide in the nickel smelting waste slag, and also have metal such as minor amount of nickel, copper, cobalt, lead, zinc and non-metallic element sulphur etc., the nickel smelting waste slag of enormous amount is done the additive replacement iron ore for the cement mill except that a small amount of at present, and all the other are all fully developed.Temperature was at 1100 ℃-1300 ℃ when the pyrogenic process nickel smelting waste slag discharged in addition, and the sensible heat after the slag discharging is not utilized effectively, and has caused a large amount of thermal waste.
At present, reclaiming metal from nickel smelting waste slag has several different methods, and wherein commonly used have the hot method of charcoal, fuming process, electric dilution method, a flotation process etc., utilizes nickel smelting waste slag to reclaim ferrous metal, and also existing abroad proven technique technology is used for reference.But, to end up till now, these technical matters processing costs are generally too high, cause its economic benefit too poor, and especially aspect saving energy and reduce the cost, various economic targets are very poor, and therefore, these technology seldom are employed so far.
Iron and steel enterprise is the energy consumption rich and influential family, with traditional SINTERING PRODUCTION technology powdered iron ore is carried out agglomeration and become an indispensable important production process in the ferrous metallurgy industry, specifically be with various powdery iron-containing raw materials, allocate an amount of fuel and flux into, add an amount of water, on agglomerating plant, make material that a series of physicochemical change take place through mixing with after making ball, mineral powder granular is cohered caked process, wherein the sintering circuit energy consumption accounts for 10% in ton steel comprehensive energy consumption, be only second to the ironmaking operation, therefore, reduce the sintering circuit energy consumption, can effectively reduce a ton steel comprehensive energy consumption.
Summary of the invention
The purpose of this invention is to provide a kind of method of utilizing nickel smelting waste slag to produce artificial high-grad iron ore deposit by new sintering process, can provide a kind of approach that effectively utilizes to nickel smelting waste slag, the sensible heat that can also make full use of nickel smelting waste slag replaces conventional sintering fuel to carry out sintering process, thereby effectively saved the required energy consumption of sintering process, also avoided environmental pollution.
For achieving the above object, the technical solution used in the present invention is:
A kind of method of utilizing nickel smelting waste slag to produce artificial high-grad iron ore deposit by new sintering process is characterized in that, comprises the steps:
A, temperature is poured in the warm sludge bag at 1100-1300 ℃ nickel smelting waste slag, through leaving standstill 10-20 minute after 5-15 minute the shaking ladle vibration;
B, the showy slag that the waste the superiors in the warm sludge bag are accounted for waste cumulative volume 3-8% are partly removed, and keep the bottom slag part that waste orlop in the warm sludge bag accounts for waste cumulative volume 3-8%, and the rest part of waste in the warm sludge bag is transferred in another warm sludge bag;
C, add iron-bearing material in the above-mentioned warm sludge bag that most of waste is housed, the consumption of iron-bearing material is the 30-100% of waste gross weight in this warm sludge bag, stirs afterwards, and iron-bearing material is evenly melted in waste;
D, the waste that will add iron-bearing material are again poured out postcooling and are got final product.
Thereby the bottom slag that wherein the warm sludge bag orlop that keeps among the step b is accounted for waste cumulative volume 3-8% partly carries out remainder after the secondary ore dressing adds recycling in the waste among the step a.
Utilize its heat energy that stand-by iron-bearing material is carried out heating, drying to reduce moisture content and to increase temperature when wherein waste cools off in the steps d.
Wherein the iron-holder of iron-bearing material is 60-65%, and iron-bearing material is at least a in the smart powder of iron, iron scale and the high-grad iron ore deposit powder.
The waste that wherein will add iron-bearing material in the steps d pour into the mould internal cooling or cylinder iron machine carry out broken again after the ingot bar cooling, screening and finishing can be used.
The product of the inventive method can be directly used in iron-smelting raw material, the irony material in producing as iron alloy, and alternative agglomerate, oxide pellet, steel cuttings, iron scale, production cost is lower, and more energy-conserving and environment-protective are a kind of new ferriferous raw materials;
Sensible heat when the inventive method has made full use of the nickel smelting waste slag discharging to the waste purification and impurity removal, reclaims ferrous metal, save heat energy, thereby obtained a kind of novel artificial high-grad iron ore deposit product, the nickel smelting waste slag of serious environment pollution has been turned waste into wealth, turned harm into good, fully utilized resource to greatest extent, not only meet national industrial policies, and save energy, reduce and pollute, for energy-saving and emission-reduction, developing a circular economy has very big meaning.The experiment proved that, the enriched ore ferrous grade that the inventive method is produced can reach 49-55%, meet request of national standard, because wherein contain the minor amount of nickel metallic element and ordinary sinter ore deposit, acid pellet are compared, this product physical strength height, anti-knocking property are good, good permeability is particularly suitable as the raw material of ironmaking, stainless steel and weathering steel, and the working of a furnace of blast furnace, electric furnace is more smooth and easy, stable when using this raw material.Simultaneously, also can be used as the ferriferous raw material in the iron alloy production, result of use is better, more energy-conservation than effects such as ordinary oxygen pellet, steel cuttings, iron scales in ferrosilicon, ferromanganese, ferrochrome production, cost is lower.
Embodiment
The inventive method still is in molten state after being particularly suitable for smelting, and typical temperature is at 1100-1300 ℃ nickel smelting waste slag, if cooled waste then needs to reheat, its economic benefit obviously can obviously descend.After the showy slag that the warm sludge bag the superiors account for waste cumulative volume 3-8% among the step b is partly removed in addition, can make additive for the cement mill and replace iron ore to use.
Because the sintering circuit energy consumption accounts for 10% in ton steel comprehensive energy consumption, the inventive method has been saved this part energy consumption fully, the environmental pollutions such as flue dust of also having avoided this part operation to cause simultaneously.
In the inventive method iron-bearing material is added waste, the ferrous metasilicate alkalescence of molten state is increased relatively, acidity weakens, thus transition is a kind of people of hot-melting type (iron) mineral products of getting rich.
