200610031958.2 disclose a kind of adhesive for fast consolidation of cold solidified pellet, and its component comprises magnesium chloride, calcium chloride, iron(ic) chloride, sodium-chlor, ammonium chloride.Binding agent with addition of amount, be the 1.5-2.0% of raw material gross weight.Yet this binding agent is under the metallurgical smelting process condition of high temperature, chlorion enters flue gas, pipeline and fume treatment auxiliary is worked the mischief, and use this binding agent, and chlorion enters in atmosphere with flue gas, also can increase the generation of toxicant dioxin.
Summary of the invention
The object of the invention be to provide a kind of use range more extensively, cost is lower and meet solidifying agent and the using method of the cold consolidation technique service requirements of metallurgy powder, and solves the chloride difficult problem of cold fixed pressure ball solidifying agent.
A kind of cold fixed ball press technique high calcium solidifying agent of realizing the object of the invention, comprises calcium sulfate, magnesium sulfate, silicon-dioxide, aluminium sesquioxide and sulphur, and in mass parts, each component concentration is as follows:
A high calcium solidifying agent, in mass parts, each component concentration is as follows:
A high calcium solidifying agent, in mass parts, each component concentration is as follows:
Calcium sulfate 30.8
Magnesium sulfate 33.3
Silicon-dioxide 0.4
A high calcium solidifying agent, in mass parts, each component concentration is as follows:
The using method of above-mentioned any one high calcium solidifying agent, the amount of allocating into of described high calcium solidifying agent is the 3-7wt% of material total mass.
After described material and described high calcium solidifying agent mix, the moisture of controlling mixture is 2-8wt%.
Described material is ion dust mud contaning and iron scale, and wherein said iron scale pulverizing and jevigating is less than 5mm to granularity, and the quality proportioning of ion dust mud contaning and iron scale is greater than 1/3.
This novel solidifying agent utilizes raw material itself to meet the feature of water fast solidifying, easy electrolysis, not only guaranteed finished ball falling and stacking intensity at pelletizing initial stage, and along with the degree of consolidation of time lapse ferrous material own deepens to have guaranteed falling and ultimate compression strength of its later stage, consolidation strength is up to 1500-3000N.Applied widely, be not only applicable to all kinds of ion dust mud contaning materials, be also applicable to the poor metallurgy powder of iron scale class macrobead or agglutinating value(of coal); And can solve chloride solidifying agent and bring the pollution problem of dioxin.And this solidifying agent raw material drawing is extensive, cheap.
