Abstract
The invention relates to a tailing shale sintered product and a preparation method thereof, wherein the tailing shale sintered product is prepared by sintering the following raw materials in percentage by weight: tailings of high-iron, low-silicon, high-calcium, low-aluminum iron: 40-85%, shale: 9-55% of fly ash: 0-26%, inner fuel: 5 to 6 percent. The preparation method comprises the following steps: 1) preparing materials: adding water into the mixed raw materials, uniformly stirring, and conveying into a storage warehouse; 2) molding: feeding the stored material into a forming machine for semi-hard plastic extrusion forming; 3) and (3) sintering: sintering for 2-7 hours under the condition of controlling the maximum temperature to be 1000-; and (3) sintering time: 24-28 hours; 4) and (5) taking out of the kiln and sorting. The invention solves the problem of adopting the process technology of making the brick by using the high-iron calcium and low-silicon aluminum iron tailings, changes the waste iron tailings into valuable, and produces various sintered products such as sintered common bricks, porous bricks, hollow bricks and the like with the quality meeting the relevant national standards, thereby having great social and economic benefits.
Description
Technical field
The present invention relates to a kind of new construction material, is a kind of mine shale sintered products specifically.
Background technology
Domestic by retrieval Relational database and Explore Related Sites, retrieving the research report document that utilizes mine tailing to produce vitrified brick has tens pieces, for example the high silicon of usefulness, the low-sulfur (SiO that are delivered of Institutes Of Technology Of Hebei's resource and environment engineering department
2Content 72.79%) iron tailings is made pavior brick, the Shenyang Jianzhu University Materials Science and Engineering is the usefulness high-silicon type mine tailing (SiO that is delivered
2Content 69.08～77.52%) produce the experimental study etc. of vitrified brick, and adopt high iron low silicon (SiO
2Content is lower than 45%) and the low ferro-aluminum mine tailing production of high calcium sintered article, Shang Weijian successfully reports.
Meishan iron mine is the famous large-scale emphasis underground mine of country; throughput is above 3,000,000 tons; second phase will reach 5,000,000 tons; the mine tailing that this ore deposit produced is high iron low silicon and the low aluminium type of high calcium; discharge the mine tailing quantity of slag up to 90 ten thousand ton to the mine tailings storehouse every year; a large amount of land occupations are had a strong impact on environment protection and reservoir area safety.Also there is similar problem in other areas, the whole nation.Therefore, how with high iron low silicon (SiO
2Content is lower than 45%) and the low ferro-aluminum mine tailing of high calcium add development and use as renewable resource, become people and urgently wish the problem that solves.
Summary of the invention
What the present invention will solve is exactly how to utilize high iron low silicon (SiO
2Content is lower than 45%) and low aluminium (CaO content the is higher than 12%) iron tailings of the high calcium technical problem of producing the sintering based article.
Because iron, the calcium contents superelevation of high iron low silicon, the low aluminium sections mine tailing of high calcium, sial content is low excessively, can be unfavorable for sintering and influence end product quality as adopting known formulations and explained hereafter to go out sintering based articles such as fired common brick, perforated brick, hollow brick.The present invention makes that by adjusting process and prescription the raw material after cooperating can satisfy the sintering process specification of quality, produces the sintered article that meets national standard.
The present invention is formed by following weight percent sintering by following raw materials according:
High iron low silicon and high calcium hang down aluminium sections mine tailing: 40-85%, shale: 55-9%, flyash: 26-0%, interior fuel: 5-6%.
Fuel is any one in coal, coal gangue, cinder or the coke bits in above-mentioned, and its particle diameter should be less than 2mm.
Above-mentioned iron tailings is high iron low silicon and high calcium low ferro-aluminum mine tailing, wherein SiO
2Content be lower than 45%, the content of CaO is higher than 12%, its chemical ingredients is as follows:
| Project | FeO | Fe 2O 3 | SiO 2 | Al 2O 3 | CaO | MgO | K 2O | Na 2O | TiO 22 | Loss on ignition |
| Content | 12.52 | 15.59 | 26.79 | 7.14 | 12.90 | 4.18 | 1.06 | 0.16 | 0.26 | 19.27 |
Plasticity index: 7.85-11.57
Preparation method of the present invention comprises the steps:
1) batching: the raw material of working good is added water stir, send into depositing stockization;
2) moulding: the material after will depositing is sent into shaper and is carried out semihard and mould extrusion moulding;
3) sintering: the control top temperature is under 1000-1080 ℃ the condition sintering 2-7 hour; Firing time: 24-28 hour
4) kiln discharge go-on-go.
The present invention can utilize high iron low silicon and the low ferro-aluminum mine tailing of high calcium to produce multiple sintering based articles such as fired common brick, perforated brick, hollow brick, and the quality product of producing satisfies the countries concerned's standard (GB5101-2003, GB13544-2000, GB13545-2003 standard).
Advantage of the present invention and technical progress are embodied in comprehensive utilization depleted iron tailings, turn waste into wealth, and have important social and economic benefit.Solved the Technology that adopts low calcium of high ferro and the brickmaking of low sial sections mine tailing.
The finished product performance index: qualified, the intensity 〉=MU10 of apparent size, lime blowing is qualified, freeze thawing is qualified.
