Abstract
The invention provides a kind of other mine tailings with phosphor tail slag or proximate component as main raw material, be aided with extra large sand, flyash or feldspar again, an amount of add micro-nucleating agent, through prepare burden, found, moulding, annealing, coring, crystallization and operations such as grinding, polishing make the marmorean method of devitrified glass.The product that makes with present method has and natural marble, grouan similar in appearance and character, has some property of glass again.
Description
The present invention relates to a kind of is that main raw material is produced the marmorean method of devitrified glass with mine tailings, particularly a kind of phosphor tail slag and mine tailings similar to phosphor tail slag composition method as the main raw material of this production used.
Existing cinder microcrystalline glass marble production method, the southern Russian Constantine, Ural, the Siberian blast-furnace slag that utilize the Soviet Union are arranged, the Lenin factory of Poland and the blast-furnace slag of Stettin factory, and the blast-furnace slag of state such as Hungary, Japan, Britain, France, East Germany, the U.S., Belgium, produce the devitrified glass marble; China has glass two station-service flyash in Shanghai to make devitrified glass (CN85100521).Do not utilize various mine tailings to produce the marmorean method of devitrified glass but still have so far.
The devitrified glass marble is a kind of type material of excellent property, and it has and natural marble, grouan similar in appearance, character.The property that also has glass.Can be used for exterior wall finish in the buildings, the container of acid and alkali-resistance, factory building, experiment table top.Or alternative steel are used to dig up mine, the equipment easy to wear in the coal separation, Cement industry, and the wear resistance that can make equipment is than improving 5-12 doubly with steel.The devitrified glass marble also is a kind of novel insulation, sound insulation, fire-retardant material.Therefore, this product has very big domestic and international market.
The phosphorus ore majority of China belongs to low-grade phosphate ore, so, the time can produce a large amount of phosphor tail slags in development and use, it not only takies a large amount of farmlands, also contaminate environment seriously.Phosphor tail slag is the keypoint treatment object of China's five big phosphorus ores, is example with Lianyungang silk screen phosphorus ore only, and discharge with 500,000 tons of quantity dischargeds every year, has formed more than 1,000 ten thousand tons little small hill near the mining area now, and is anxious to be solved.
Task of the present invention is to provide a kind of improved, is applicable to the phosphor tail slag to be that main raw material is produced the marmorean method of devitrified glass.
Task of the present invention is finished as follows:
Known devitrified glass marble belongs to CaO-AlO-SiO series substantially, and its more satisfactory compositing range is:
Composition: SiO
2Al
2O
3RO RO
2Fe
2O

0-3 1-4 0-2
Select for use phosphor tail slag or other mine tailings, auxiliary material (as extra large sand, perlite, flyash, feldspar, barite by the chemical ingredients of above composition.) and various metal oxide as nucleating agent (as zinc oxide, chromic oxide, titanium oxide, ferric oxide, manganese oxide.But) also fluorochemical (as Calcium Fluoride (Fluorspan)).Calculate the consumption of various materials by above-mentioned tabular composition.Then, correct weighing stirs evenly whole materials, drops in crucible oven or the tank furnace and melts, and temperature of fusion is controlled at and is lower than 1450 ℃, and the best is that the hold-time is 10-16 hour in 1380 ℃-1450 ℃ scope.When obtaining the good glass metal of clarifying fusing, available rolling process or pouring method are made sheet material requiring the die for molding of specification.750 ℃ of annealing down, best annealing temperature is in 560 ℃ of-600 ℃ of scopes, and keeps 1-3 hour with this sheet material.Be warming up to 5 ℃/minute speed and carry out coring below 800 ℃ and handle, nucleation time is 1-3 hour.Its best nucleation temperature is at 650 °-700 ℃.With 1 °-5 ℃/minute heat-up rate, temperature is reached carry out the crystallization processing below 950 ℃ again, crystallization time is 1-3 hour.Its optimum crystallization temperature is 780 °-900 ℃.Sheet material after above processing, the thick sheet material of mine tailings devitrified glass marble that the cooling back just can obtain having good physical and chemical performance and mechanical property becomes finished product sheet material again after grinding, polishing.
The gordian technique of present method is that crystallization is handled, otherwise sheet material can be out of shape, ftractures or occur nonconforming thing phase.
By following embodiment invention is described in further detail.
Embodiment 1:
Prescription is shown in tabular:
Material name: phosphor tail slag sea sand perlite powder coal ash
Weighing (%): 50 10 20 10
Barite Calcium Fluoride (Fluorspan) zinc oxide
4 4 2
With the various raw materials of tabular, accurately weighing stirs, and drops in crucible oven or the tank furnace, is melted in 1380 °-1450 ℃ temperature range evenly.Clarifying glass metal with the die for molding of teeming practice at certain specification, is taken out this sheet forming, in 560 °-600 ℃ temperature range, anneal, and kept 1-2 hour.With 1-5 ℃/minute speed intensification, the coring processing was carried out in the interior maintenance of temperature range that reaches 650 °-700 ℃ in 1-2 hour again; And then be heated to 800 °-900 ℃, and keep carrying out in 1-2 hour crystallization and handle with 1 °-5 ℃/minute heat-up rate.So just make the marmorean raw product of devitrified glass, after grinding, polishing, promptly become qualified product again.
Embodiment 2:
It is as follows to fill a prescription:
Material name: mine tailings perlite Calcium Fluoride (Fluorspan) feldspar
Weighing (%): 53.58 28.52 8.95 8.95
With above each component raw material, accurately after the weighing, stir, drop in the tank furnace, melt being lower than under 1450 ℃ the temperature, when obtaining clarifying glass metal, can carry out moulding, annealing, coring, crystallization by the handling procedure of embodiment 1 and handle.After grinding and polishing, can make qualified devitrified glass marble slabs.
