Description
Technical field
The present invention relates to clinker, be specifically related to a kind of clinker utilizing non-ferrous metal metallurgy slag to generate.
Background technology
At present, China, during nonferrous production, creates substantial amounts of iron slag.In slag not only containing 40%～
50% ferrum element, contains part non-ferrous metal element simultaneously, and corrosivity is high, add long-term outdoor bank up during, warp
Weathering and drenching with rain, the metallic element in waste residue is easy for being discharged in surrounding, the most not only the ecological ring to periphery
Border causes immeasurable severe contamination, and wastes substantial amounts of metals resources.At present non-ferrous metal metallurgy slag is utilized
Lay particular emphasis on and reclaim metals resources therein, substantial amounts of secondary slag can be produced during utilizing, often utilize 1 ton of copper through calculating
Slag, can produce the secondary slag of 0.7 ton, processes without effective ways the most temporarily, and the utilization rate therefore causing metallurgical slag is low and discarded
Thing conversion ratio is low.Research finds: does not contain only a large amount of metallic element in metallurgical slag and contains SiO simultaneously2、MgO、CaO、Al2O3Etc. group
Unit, close with the main component of cement, if it is possible to by after metal recovery in nonferrous smelting slag simultaneously by stone-like pulse constituent element system in slag
Become cement raw material, it is possible to achieve real fully utilized of coloured slag, this not only carries forward vigorously sustainable development and foundation with China
Environment economizing type industrial policy is consistent, and more smelter and cement industry makes greatly contribution.
Summary of the invention
Goal of the invention: the problem existed for prior art, proposition one is applied widely, with short production cycle, operation is simple
List, low cost, the energy consumption clinker utilizing non-ferrous metal metallurgy slag to generate low, free of contamination.
Technical scheme: to achieve these goals, the cement utilizing non-ferrous metal metallurgy slag to generate as described herein is ripe
Material, mainly by made by the raw material of following weight portion: non-ferrous metal metallurgy slag 100 parts, reducing agent 20-30 part, solvent 10-30
Part, binding agent 5-10 part, additive 12-45 part.
As preferably, MgO < 5% in described non-ferrous metal metallurgy slag.
As preferably, described reducing agent is a kind of in coke powder, brown coal, bituminous coal, anthracite or combination that certain is several.
As preferably, described reducing agent is a kind of in coke powder, brown coal, bituminous coal, anthracite or combination that certain is several.
As preferably, solvent is a kind of in limestone, Calx, sodium carbonate, fluorite, industrial soda or combination that certain is several.
As preferably, described binding agent is one or both in bentonite, starch.
As preferably, described additive is calcium fluoride, calcium oxide, the one of aluminium oxide or certain several combination.
As preferably, described clinker is by made by following steps:
(1) non-ferrous metal metallurgy slag, reducing agent, solvent, binding agent are fully mixed by formula；
(2) mixture being heated to 800-1300 DEG C after drying, the time is 10-30 minute, reduces；
(3) reduzate in step (2) being heated to 1500-1700 DEG C, slag sluicing system, after smelting, molten iron is used for ferroalloy
Producing, pulp water changes into clinker.
As preferably, step (2) described mixture carries out being reduced into metallized pellet.
As preferably, step (3) described pulp water changes into clinker and concretely comprises the following steps pulp water inflow slag ladle, sets in slag ladle
Being equipped with thermal source, thermal source is set to 1600-1650 DEG C, uses gas to be blown into additive bottom slag ladle, and the response time is that 30-60 divides
Clock.This process is the process generating clinker, and pulp water flows into after slag ladle heat loss, cause temperature to reduce 1300～
About 1400 DEG C, the temperature of generation clinker, at 1500-1600 DEG C, is protected so having also needed to a thermal source inside slag ladle
Temperature heating, it is to avoid heating reduces process procedure again.
Beneficial effect: compared with prior art, the present invention utilizes the clinker that non-ferrous metal metallurgy slag generates, have as
Lower advantage: the present invention generates clinker by nonferrous smelting slag, by regulation temperature and nonferrous smelting slag, reducing agent, molten
Agent, binding agent, the proportioning of additive fully utilize nonferrous smelting slag, it is achieved that utilizing without solid waste of nonferrous smelting slag；Again this
On the basis of, obtaining, containing micro-nickel, cobalt, the ferroalloy of copper, the requirement of STEELMAKING PRODUCTION raw material to be reached, product outlet is clear
Chu, gangue content is converted into clinker simultaneously, it is achieved comprehensive utilization.
The present invention makes the ferrum in nonferrous smelting slag and gangue content utilize simultaneously, ferroalloy will be produced and manufacture cement is ripe
Twice intensification of material becomes once heating up, and energy efficient, simultaneously by fully utilized for metal smelt slag, does not has the product of secondary residue
Raw；By METAL EXTRACTION in metallurgical slag out, stone-like pulse will be used for manufacture of cement as useful component, and process procedure greatly reduces, and subtracts
Few dust, exhaust emission, widened the market application of product, it is often more important that can process the nonferrous smelting that current heap is abandoned
Slag, produces without new solid waste, it is achieved reach environmental conservation while economic interests.
