Description
Technical field
The invention belongs to solid waste resource reutilization field, being specifically related to the stainless steel slag is that in main raw material and dedusting ash of stainless steel, quartz sand, flyash, the cullet one or more are auxiliary material devitrified glass and preparation method thereof through allotment.
Background technology
Along with the development of steel industry, the output of ferrous metallurgy slag is increasing.China's stainless steel output reached 1,130 ten thousand tons in 2010, had produced stainless steel slag and 200,000 tons of dedusting ash of stainless steel of 2,260,000 tons.It is different from other metallurgical slag because of containing heavy metal chromium in stainless steel slag and the dedusting ash of stainless steel, and oozing out of heavy metal chromium has the serious environmental risk, belongs to danger wastes.At present, the stainless steel slag of domestic each stainless steel manufacturer and dedusting ash of stainless steel carry out that the slag field is stacked, preparation cement, build the road etc., and the stainless steel slag of stacking and dedusting ash of stainless steel are easy to ooze out Cr
+ 3And under physical environment, be oxidized to Cr
+ 6, chromium ion is easy to ooze out from concrete, cement products under certain sour environment simultaneously, the water-soluble migration, and prolong the seepage discharge increase in time, and cause serious water to pollute, cause human body mucosal ulcer even cancer.Therefore, the green composite utilization of stainless steel slag and dedusting ash of stainless steel is the difficult problem that metallurgy industry is badly in need of solution.
At present, a lot of producers utilize stainless steel slag and other raw material to prepare products such as cement, concrete and pottery.For example, Japanese Patent (JPA51083623) discloses at stainless steel slag and has added other oxide compound, feeds carbonic acid gas under certain condition and prepares light weight concrete, though these products can utilize stainless steel slag, Cr
+ 6Ooze out from these goods through regular meeting, pollute, and be difficult to these products are recycled.
Therefore in order to address these problems, to have proposed a lot of methods and stoped Cr in the stainless steel slag
+ 6Ooze out for example Japanese publication (JP-A) No. Hei-6-171993) proposed, when toppling over the stainless steel slag of molten state, in stainless steel slag, add aluminium ash and magnesium oxide-based industrial waste and stop oozing out of chromium ion in the slag.But because molten steel viscosity is too big, toppling process can not carry out fine as to mix, and therefore the chromic oxide that can not be completely fixed in the slag stops Cr
+ 6Ooze out.In addition, the United States Patent (USP) (US 6,732,547 B1) of Japanese JFE Iron And Steel Company application by in stainless steel refining process in covering slag a certain amount of sulfide of interpolation (S is less than 0.20%) stop Cr in the stainless steel slag
+ 6Ooze out.This method is to Cr
+ 6Ooze out good interception arranged, this stainless steel slag can be applied in preparation cement and aspect such as pave the way, but this method has reduced the viscosity of slag, and molten steel produced pollutes.In order at room temperature to reduce Cr
+ 6Seepage discharge, utilize ferrous sulfate to make Cr as reductive agent
+ 6Be reduced into Cr
+ 3To reduce the harm of environment.Japanese Patent JP-A-53028563 disclose a kind of under sour environment, utilize calcium sulfite as reductive agent Cr
+ 6Be reduced into Cr
+ 3, add oxyhydroxide then and make Cr
+ 3Be transformed into the chromium hydroxide compound, add in the cement at last and fix.This patent with the high-valued utilization again of stainless steel slag, probably is not reduced into Cr again under well-oxygenated environment
+ 6Cause the serious environmental burden.
Green is high-valued to be utilized again in order stainless steel slag is carried out, and prepares the attention that devitrified glass obtains people with it as main raw material.Devitrified glass does not absorb water, and resistance to acids and bases is strong, and the chromium element serves as the crystallite nucleating agent, and good fixed action is arranged, and stops Cr
+ 6Pollution problem.In addition, the devitrified glass waste material can repeatedly melt down and utilize.Chinese invention patent CN101838108A(application number: 201010154436.8 Shen Qing Publication dates: 2010.09.22) disclose a kind of recovery of stainless steel tailings and utilization of coal ash method, by adding yellow soda ash and barium oxide, mix with stainless steel slag, flyash and quartz sand proportioning, adopt fusing, cast, annealing, coring, crystallization and processing to obtain devitrified glass.This application can be utilized stainless steel slag and fly-ash Preparation devitrified glass, owing to added yellow soda ash and barium oxide industrial chemicals, production cost has improved.
The invention provides a kind of is raw material with stainless steel slag, dedusting ash of stainless steel, quartz sand, flyash, cullet solid waste, do not add other industrial chemicals, by the low-cost method for preparing devitrified glass of composition allotment, not only multiple solid waste is carried out the green composite cycling and reutilization, solved Cr in stainless steel slag and the dedusting ash of stainless steel
+ 6Ooze out caused problem of environmental pollution.The devitrified glass of the present invention preparation has that cost is low, raw material sources are extensive, is fit to large-scale industrial production, and product can be widely used in building, decoration and industrial antisepsis field.
Summary of the invention
The present situation of utilizing at stainless steel slag and dedusting ash of stainless steel, the invention provides the method for stainless steel slag, dedusting ash of stainless steel, quartz sand, flyash, the utilization of cullet solid waste low cost green composite, make the useless admittedly low-cost high-efficiency increment utilization again that obtains, stop Cr in the stainless steel slag
+ 6Ooze out caused problem of environmental pollution.
Devitrified glass of the present invention not only makes stainless steel slag and dedusting ash of stainless steel can prepare devitrified glass by the composition adjustment, multiple solid waste is carried out comprehensive cycling and reutilization, and having solved the caused problem of environmental pollution of heavy metal chromium, it comprises F, Cr simultaneously
