Description
Technical field
The binding agent used during the present invention relates to a kind of metal smelt, particularly relates to a kind of in the use of metallurgical briquetting stage
Binding agent.
Background technology
Metallurgical briquetting is, after thin fine ore adds a small amount of binding agent mixing, to rely on the mechanical force of capillary force and rotary motion to cause
The green-ball of diameter 8～16mm, is then dried, the crystalline substance of Fe2O3 recrystallization under high temperature oxidation stability atmosphere on roasting apparatus
Bridged bond be consolidated into of high grade, intensity good, even-grained spherical iron-smelting raw material.
The binding agent that metallurgical briquetting uses generally comprises two big classes: one is organic bond, and two is inorganic bond.Organic viscous
Mixture is because price is high, consumption is few, dispersion is difficult, and the pellet forming process of Iron Ore Powder is had harsh requirement, the less use of China.
Inorganic bond main component is bentonite, and part uses white lime or other clay class binding agents.China's bentonite resource enriches,
Exploitation processing cost is low, strong adaptability, controlled range wide, is main pelletizing binder.
Bentonitic main component is Nax(H2O)4(Al2-xMg0.83)Si4O10)(OH)2, in the process carrying out metal smelt it is
Improve the characteristic smelted, it is necessary to eliminate bentonitic residual to the full extent, have to disappear because of bentonitic smelting
Consumption is higher than the fuel of tradition ironmaking mode one times, and the raw material for neutralizing reaction higher than tradition ironmaking mode several times, than
Such as lime stone or dolomite.And according to statistics, China's metallurgical briquetting annual production is up to 1.3 hundred million tons, year consumes bentonite nearly 3,000,000
Ton, this shows that annual China in order to smelt iron the fuel consumed and can be with millions of tons for neutralizing the raw material of reaction more
Meter, not only causes the consumption of huge fuel and natural resources, and environment be also result in tremendous influence.
Summary of the invention
The present invention mainly to solve the technical problem that and be to provide a kind of composite adhesive for metallurgical briquetting, this composite adhesive
Be conducive to improving follow-up smelted metal smelt performance, reduce and smelt energy consumption, reduce environmental pollution.
The present invention to solve the technical problem that further and be to provide a kind of composite adhesive for metallurgical briquetting, and this is composite adhered
The optional space of raw material of agent is relatively big, thus its thin fine ore kind being suitable for is wider.
The present invention mainly to solve the technical problem that and also include providing a kind of method producing above-mentioned composite adhesive, this producer
Method program is simple, with low cost, yield rate is high.
A kind of composite adhesive for metallurgical briquetting of the present invention, including organic powder and bentonite, described organic powder and bentonite
Mass ratio be 1:1；Described organic powder includes disperse materials and organic bond: by percentage to the quality, disperse materials:
95%～99.5%, organic bond: 0.5%～5%.Described disperse materials is hydrophilic to burn lost article material.Described hydrophilic burn lost article
Material is sodium humate, coal, carbonization stalk or carbonization rice husk.
A kind of composite adhesive for metallurgical briquetting of the present invention, the wherein said hydrophilic water content of lost article material of burning is less than 3%.
A kind of composite adhesive for metallurgical briquetting of the present invention, wherein said organic bond is sodium carboxymethyl cellulose, hydroxyl
Propyl methocel, starch ether thickening agent or polyacrylamide.
A kind of method producing above-mentioned composite adhesive of the present invention, comprises the steps:
A) feeding；By percentage to the quality, according to disperse materials: 95%～99.5%, organic bond: 0.5%～5%；(point
Bulk cargo+organic bond): the ratio of bentonite=1:1 weighs disperse materials, organic bond and bentonite respectively；
B) organic powder is made；The disperse materials weighed in step a is put in grinder with organic bond and is ground, until
200 mesh granule accountings are more than 90%, and the most organic powder completes；
C) composite adhesive is made；The bentonite weighed in the organic powder made in step b and step a is put into batch mixer
In be sufficiently mixed, so far composite adhesive just completes.
A kind of composite adhesive for metallurgical briquetting of the present invention is owing to reducing bentonitic content, thus is using the present invention
A kind of composite adhesive for metallurgical briquetting reduces fuel and for neutralizing the former of reaction during carrying out metal smelt
The usage amount of material, had both saved resource, had protected again environment.
Disperse materials used in a kind of composite adhesive for metallurgical briquetting of the present invention i.e. can be selected for hydrophilic burning lost article material,
Also can be selected for ferrous material.More specifically dispersed material may select sodium humate, coal, carbonization stalk or carbonization rice husk,
Siderite, limonite, bloodstone, metallurgical dedusting ash or steel-smelting sewage sludge can also be selected.The why optional model of disperse materials
Enclose so wide, its purpose is to adapt to the metallurgical briquetting of different thin fine ores and local resource at a low price can be used and
Reduce cost.
A kind of method producing above-mentioned composite adhesive of the present invention only includes three steps, and the equipment that this three steps are used
It is all conventional equipment, it can be seen that the method program producing above-mentioned composite adhesive is simple, without putting into too many cost, and institute
The composite adhesive yield rate produced is high.
Detailed description of the invention
A kind of composite adhesive for metallurgical briquetting, including organic powder and bentonite, described organic powder and bentonitic quality
Ratio is 1:1；Described organic powder includes disperse materials and organic bond: by percentage to the quality, disperse materials: 95%～99.5%,
Organic bond: 0.5%～5%.
Wherein said disperse materials both can be selected for the hydrophilic lost article material that burns and also can be selected for hydrophilic ferrous material, but no matter which kind of used
Disperse materials is all it has to be ensured that the disperse materials water content used is less than 3%, because only that work as the water content of disperse materials less than 3%
Time, organic bond just will not be concentrated on the disperse materials being gathered in a certain little scope, just can avoid the conglomeration of disperse materials, just meeting
Organic bond is the most uniformly mixed with disperse materials, and then the quality that the follow-up metallurgical briquetting of guarantee makes.
When disperse materials be hydrophilic burn lost article material time, concrete can select sodium humate, coal, carbonization stalk or carbonization rice
Shell.
When disperse materials is hydrophilic ferrous material, concrete can select siderite, limonite, bloodstone, metallurgical dedusting ash
Or steel-smelting sewage sludge.
According to the difference of selected disperse materials, the organic bond used also should be from sodium carboxymethyl cellulose, hydroxypropyl
Methylcellulose, starch ether thickening agent or polyacrylamide select to use.
The market price that following table is each organic bond and the breeze kind being suitable for thereof, and its in composite adhesive relatively
