Description
Technical field
The present invention relates to be used for the sticker and the application method thereof of the cold solid moulding of fine ore, specifically relate to a kind of metal powder ore cold consolidation sos such as silicon, manganese, nickel, chromium that are used for, belong to field of metallurgy to substitute the sticker and the application method thereof of agglomerate.
Background technology
China is iron alloy big producing country, and along with exploitation of mineral resources, lump ore and fine ore and the concentrate ratio of selecting through richness increase considerably; Account for 25% like lump ore in 1,200 ten thousand tons of the chrome ore world YO; Fine ore (＜8mm) account for 75%, in addition, the price differential of lump ore and fine ore is also increasing.Chromium powder ore deposit price is lower 30～40 dollars/ton than lump ore.
There is no hiding it, and fine ore will become the main mineral resources of alloy production future enterprise.But in alloy smelting technology, fine ore too much can make the furnace charge air permeability variation with addition of surpassing 5%, worsens the working of a furnace, so fine ore must carry out pre-treatment before using.Fine ore pre-treatment main path is agglomeration, and the method for agglomeration at present has: pelletizing method, sintering process and cold solid pressure ball method, domestic alloy producer mainly adopts sintering process.But since sintering process particularly the local method sintering have insoluble problem in the short period of time such as small scale, energy consumption be high, seriously polluted, the strict limit production of environmental administration.Because some ore deposit fusing point very high (like picotite), be difficult to form low-melting liquid phase during sintering in addition, and some ore deposit belongs to acid sinter ore (like the chromium agglomerate), yield rate is on the low side, and the strength ratio of agglomerate is relatively poor.
Summary of the invention
Technical problem to be solved by this invention is the deficiency that overcomes prior art; A kind of sticker and application method thereof of metal powder ore cold consolidation so as to substitute for sinter ore are provided; Use this sticker can prepare various powder ore pellets (piece) and process the compound ball that contains fine ore, fusing assistant, reductive agent according to smelting ore proportioning rate; Finished product substitutes agglomerate fully as being the alloy smelting furnace charge respectively.
Technical problem to be solved by this invention realizes through following technological approaches:
A kind of sticker that is used for the cold solid moulding of fine ore, form by A, two kinds of components of B:
The A component is made up of the raw material of following weight part: 10～22 parts of tackiness agent, 1～7 part in solidifying agent, 60～85 parts of modification dedusting ash;
The B component: initiator, by weight, the B component is 10%～25% of an A component.
Wherein, described tackiness agent is any or their more than one mixtures formed with arbitrary proportion among vegetable-protein glue, SEPIGEL 305, the Z 150PH three; Described solidifying agent is Sodium Silicofluoride 98min or tripoly phosphate sodium STPP; Described modification dedusting ash is that the alloy dedusting ash forms through silane coupler modified; Described initiator is water-soluble middle strong inorganic base, for example yellow soda ash, Pottasium Hydroxide, sodium hydroxide etc.
Described modification dedusting ash adopts following method modification to obtain:
Step 1: it is 1%～5% solution that the mixed solvent of silane coupling agent water or water and ethanol arbitrary proportion is mixed with weight percent, and dosage of silane coupling agent is 0.1～0.5% of a dedusting ash weight;
Step 2: step 1 gained solution evenly is sprayed on the dedusting ash, stirred 10～20 minutes;
Step 3: dedusting ash is promptly got 100～120 ℃ of oven dry.
Said alloy dedusting ash is one or both mixtures formed with arbitrary proportion in the alloy production producer sack cleaner gains such as silicon system, manganese system, nickel system, chromium system; The preferred amino one type of silane coupling agent of said silane coupling agent, for example γ-An Jibingjisanyiyangjiguiwan coupling agent, phenylamino Union carbide A-162 coupling agent, 3-TSL 8330 coupling agent etc.
The used raw material of the present invention can obtain from domestic and international Chemical market and metallurgical Mineral resources market, and its specification meets industry standard and gets final product.
Another technical problem to be solved by this invention provides the application of a kind of above-mentioned sticker in metal powder ore cold consolidation so.
Another technical problem to be solved by this invention realizes through following technological approaches:
Said sticker is used for metal powder ore cold consolidation so, and concrete steps are following:
Step 1: take by weighing following each material by weight: fine ore (particle diameter: 0-12mm) 100 parts, 5～15 parts of sticker A components, 1～2 part of B component, 6～10 parts in water;
Step 2: the step is gathered fine ore, the A component abundant mixing in machine,massing that takes by weighing in, get compound 1;
Step 3: the step is gathered the B components dissolved that takes by weighing in one in water, obtain the aqueous solution;
Step 4: the aqueous solution of gained in the step 3 is sprayed on the compound 1 that is in whipped state equably, continues to stir, get compound 2;
Step 5: gained compound 2 is used the shaper moulding, pile up naturally after the moulding, be finished product.
Wherein, the churning time described in the step 4 is preferably 10～20 minutes; Piling up naturally described in the step 5 is preferably accumulation 24～72 hours, and described moulding is with shaper described compound 2 to be caused ball-type or piece type.
The bonding mechanism of sticker according to the invention is following:
Tackiness agent can improve the plasticity of compound, improves the initial strength of moulding product; Activated silica in the modification dedusting ash and initiator for reaction heat release activate solidifying agent and make the reaction aggravation, and liberated heat promotes the resultant of reaction gelling, and finished product rapid drying is fixed, under the normal temperature in 24～72 hours finished product ultimate compression strength can reach more than the 2000N.
Use sticker of the present invention can prepare various powder ore pellets (piece) and process the compound ball that contains fine ore, fusing assistant, reductive agent according to smelting ore proportioning rate; Finished product substitutes agglomerate fully as iron alloy (like Si system alloy, Mn series alloy, nickel system alloy, chromium alloy etc.) smelting furnace material.The cold solid moulding process that this sticker is used for fine ore is simple, and its unique bonding mechanism can make full use of secondary resource, and all auxiliary products of alloy production are fully utilized, and accomplishes that really environmental protection do not have three wastes production, helps simultaneously reducing production costs.
