Description
Technical field
The present invention relates to field of steel metallurgy, particularly one freezes off knot ball press technique high calcium consolidating agent and makes
Use method.
Background technology
Metallurgical industry production process can produce substantial amounts of flue dust, mud, iron scale and other powderies reclaim
Thing, the iron-holder of these powdery regenerants be up to 45% and more than, utilize cold-consolidation pellet process to process these
Granular material, have that technique is simple, small investment, instant effect, the saving energy, low cost and other advantages.According to system
Meter China iron and steel annual production 3.5 hundred million tons, the iron content secondary iron-containing resource of association the most about produces more than ten million ton,
As binding agent, mostly there is green-ball pulverization rate speed high, dry in commonly used bentonite, sodium silicate, cement
The problem that degree is slow, intensity is low, ferrous grade reduces.
200510026046.1 disclose a kind of adhesive for fast consolidation of cold solidified pellet, its component includes oxidation
Calcium, silicon dioxide, magnesium oxide, aluminium sesquioxide, ferrum oxide and manganese oxide.Its consolidating agent is applied to iron content
What dirt mud or ion dust mud contaning contained freezes off in knot ball press technique.But, this binding agent is smelted for metallurgy, has
Certain material limitation, the material not being suitable for the bulky grains such as iron scale or cohesiveness difference freezes off knot pressure ball
Technique.
200610031958.2 disclose a kind of adhesive for fast consolidation of cold solidified pellet, its component includes chlorination
Magnesium, calcium chloride, iron chloride, sodium chloride, ammonium chloride.Binding agent is raw material gross weight with addition of amount
1.5-2.0%.But, this binding agent is under the metallurgical smelting process condition of high temperature, and chloride ion enters flue gas,
Working the mischief pipeline and fume treatment auxiliary, and use this binding agent, chloride ion enters in air with flue gas,
Also can increase the generation of toxicant two English.
Summary of the invention
It is an object of the present invention to provide a kind of range more extensively, cost is lower and meets metallurgy powder and freezes off knot
Technique uses the consolidating agent and using method required, and solves to freeze off the difficult problem that knot pressure ball consolidating agent is chloride.
The one realizing the object of the invention freezes off knot ball press technique high calcium consolidating agent, including calcium sulfate, sulfur
Acid magnesium, silicon dioxide, aluminium sesquioxide and sulfur, in terms of mass parts, each constituent content is as follows:
A kind of high calcium consolidating agent, in terms of mass parts, each constituent content is as follows:
A kind of high calcium consolidating agent, in terms of mass parts, each constituent content is as follows:
Calcium sulfate 30.8
Magnesium sulfate 33.3
Silicon dioxide 0.4
A kind of high calcium consolidating agent, in terms of mass parts, each constituent content is as follows:
The using method of any of the above-described high calcium consolidating agent, the amount of allocating into of described high calcium consolidating agent is that material is total
The 3-7wt% of quality.
After described material mixes with described high calcium consolidating agent, the moisture controlling mixed material is 2-8wt%.
Described material is ion dust mud contaning and iron scale, and wherein said iron scale pulverizing and jevigating is less than to granularity
5mm, ion dust mud contaning is more than 1/3 with the quality proportioning of iron scale.
This novel consolidating agent utilizes raw material itself to meet water fast solidifying, the feature of easily electrolysis, not only ensure that
Finished ball falls and stacks intensity the pelletizing initial stage, and passage ferrous material itself consolidates journey over time
Degree is deepened to ensure that falling and comprcssive strength of its later stage, and consolidation strength is up to 1500-3000N.The scope of application
Extensively, be applicable not only to all kinds of ion dust mud contaning material, apply also for iron scale class bulky grain or cohesiveness difference
Metallurgy powder；And can solve the problem that the two English pollution problems that chloride consolidating agent brings.And the former material of this consolidating agent
Material is drawn materials extensive, cheap.
