Description

A kind of recycling iron on line from iron-containing industrial slag and prepare the method for glass ceramics frit
Technical field
The invention belongs to the technical field of comprehensive utilization of resources and material preparation, especially in metallurgical cinder high value added utilization and devitrified glass preparation field.
Background technology
As everyone knows, the a large amount of high temperature iron content slag of discharging in the industry production such as China's metallurgy, the bessemer furnace slag, electric furnace slag, stainless steel slag, the nickel slag that comprise molten state, and ferruginous molten state ferroalloy slag, refining slag, liquid slag from power plant, desulfurization slag, phosphorus slag etc.
These high-temperature slags generally adopt the method for utilizing again after the direct cooling at present, and there is the difficult problem of the high value added utilization of sensible heat utilization, the plain resources effective recovery of iron, slag in this method, and fails to solve always.Cooled solid slag can only reclaim 15% iron through the traditional method of graded crushing magnetic separation, and second half iron is present in non magnetic or part weak magnetism oxide compound in and can't separate.Simultaneously, high-temperature slag deslagging temperature〉1400 ℃, have heat quality height, quantity big (sensible heat〉60kgce/t).Yet prior art fails to realize the utilization of slag heat, and a large amount of sensible heats are directly cooled waste in air.Cooled slag is mostly as low value-added utilization such as cement mixture, roadbed material or can not effectively utilize and store up in a large number.
Devitrified glass is called glass-ceramic again, is the parent glass with specific composition, and a class that makes by the control crystallization in heat-processed contains the polycrystalline solid material that a large amount of crystallites reach glassy phase mutually.
On technology, the preparation process of devitrified glass has 1500 ℃ of left and right sides high-temperature fusion of raw material and 700 ~ 1000 ℃ of heat treated two heat-processedes of parent glass, and first high-temperature fusion process and slag melt temperature are approaching.
On forming, CaO-Al 2O 3-SiO 2Microcrystalline glass in series is one of them important class.The major ingredient of this class devitrified glass is SiO 2, Al 2O 3, CaO and MgO, approaching with the composition of slag.
Therefore, appropriately adjust iron and steel slag component and temperature under the high temperature fused state, just steel slag directly can be utilized as the high-temperature fusion raw material of devitrified glass, thereby avoided traditional devitrified glass raw material high energy consumption melting process.
To CaO-Al 2O 3-SiO 2Be the existing very long history of research of cinder microcrystalline glass.Last century the fifties end, cinder microcrystalline glass is succeeded in developing in USSR (Union of Soviet Socialist Republics), subsequently, is the CaO-Al of representative with the cinder microcrystalline glass 2O 3-SiO 2The microcrystalline glass in series fast development, and realized industrialization production.Because CaO-Al 2O 3-SiO 2Microcrystalline glass in series has the advantages that bending resistance, resistance to compression and shock resistance are good, chemical stability good, wear resistance is strong, has been widely used as high-grade construction decoration material and has substituted natural granite and high-grade wall floor tile; Be applied to fields such as metallurgy, chemical industry, machinery, building materials, the energy simultaneously as wear-resisting, corrosion resistant material.
Both at home and abroad the investigator is (as license number: CN101125735 B; Application number: 200710054035.3; Application number: 200710010130.3; Application number: 200410073239.8) to CaO-Al 2O 3-SiO 2The research of microcrystalline glass in series is mainly enlarging raw material sources, is improving the solid waste volume, is exploring devitrified glass and form mechanism, reduction and reclaim and carry out extensive work aspect the molten iron in the slag.Yet, more than study the tradition that all adopts cold slag remelting to prepare devitrified glass and utilize technology.At present, the CaO-Al on the market 2O 3-SiO 2Microcrystalline glass in series adopts this traditional technology to utilize waste residue not have clear superiority still based on natural mineral raw.Its key issue is how to reduce this process energy consumption and guarantees quality product.
Recently, many investigators attempt directly high-temperature slag being prepared into devitrified glass, as patent " slag microcrystalline glass directly made by industry furnace molten cinder " (application number: 91102237.6), " a kind of method of utilizing thermal power plant's liquid sludge-removing furnace to prepare sintered glass-ceramics " (application number: 200810018384.4), " comprehensive utilization yellow phosphorus slag and tail gas are produced the method for devitrified glass " (application number: 200710077733.5).But all adopt single stage method in these patents, promptly directly hot industry waste residue upgrading is become to satisfy the qualified slag of devitrified glass ingredient requirement, do not have the content of iron recovery and coarse adjustment upgrading.
Summary of the invention
One of purpose of the present invention: propose to utilize simultaneously the high value added utilization method of iron-contained industrial slag heat, iron, slag, guaranteed not only obvious social benefit of the present invention, technical feasibility, and have good economic benefit equally.By the slag alternative materials of directly utilizing industry to discharge, avoid the energy consumption of fusion industrial residue again, than traditional technology energy efficient 120kgce/T, reduce discharging CO 2300kg/T; Directly reclaim iron and will obtain high temperature liquid iron, be worth about 2200 yuan/ton; The preparation glass ceramics frit is worth about 6000 yuan/ton.
Two of purpose of the present invention: the two-step approach process modifying process of setting up online " coarse adjustment upgrading reduced iron "+" the fine tuning upgrading prepares frit ", solve the slag metallic reducing and reclaim the contradiction of controlling with quality of materials, that is: show the optimum alkalinity 0.8 ~ 1.25 of the iron-contained industrial slag basicity being adjusted to reducing iron oxides, this process is a reducing atmosphere; Slag basicity after then slag iron being separated is adjusted to the basicity 0.25 ~ 0.90 of common cinder microcrystalline glass, and this process is an air atmosphere.
Three of purpose of the present invention: a kind of method of utilizing industrial solid castoff in a large number is provided, the technology of i.e. " coarse adjustment "+" fine tuning " makes, in the technology of " coarse adjustment upgrading reduced iron ", can be used as modification agent and add a large amount of solid waste, allow the fluctuation in the modification agent composition certain limit; Slag composition is carried out meticulous adjustment by modification agent and adjustment agent again in " fine tuning upgrading " process, guarantee that the slag composition meets the demands.
Four of purpose of the present invention: propose devitrified glass feedstock production (high-temperature fusion) and prepare the technology that (thermal treatment) separates with the devitrified glass finished product, that is: do not prepare devitrified glass at the scene of discharge slags such as metallurgy, but preparation devitrified glass raw material---frit, then frit is transported to other place and further become devitrified glass, perhaps directly as commercial articles vending through prepared such as Overheating Treatment.Adopt the advantage of this technology to be that slag utilizes technology succinct more, flexibly, and its required space can save greatly, can satisfy the reality at existing industrial production scene.
