The process comprises the following steps: stirring smelted liquid titanium-bearing blast furnace slag evenly; molding by casting; and cooling to form a building block. The building block is simple and feasible in process, does not need pretreatment of layer pouring and the like on the titanium-bearing blast furnace slag, and is free of other raw materials. The crushing value of the building block produced by the process disclosed by the invention is smaller than or equal to 10%, and is obviously improved in comparison with the crushing value of 17%-22% of the original building block prepared from the titanium-bearing blast furnace slag.
Description
Technical field
The invention belongs to blast furnace slag field of comprehensive utilization, be specifically related to a kind of titanium-containing blast furnace slag and prepare gained building block and technique thereof.
Background technology
At present, the treatment process of titanium-containing blast furnace slag is mainly hot application, shrend, carries titanium etc., and these methods not only can cause too much the taking of land resources, and to increasing the pressure of environment protection.Titanium-containing blast furnace slag is made building block, not only utilization of waste material has been carried out to titanium-containing blast furnace slag, decrease taking and protecting environment land resources.Titanium-containing blast furnace slag mainly consists of TiO
2, CaO, SiO
2, MgO and A1
2o
3, wherein TiO
2content is 13% ~ 18%.
In prior art, prepared from Ti-containing blast-furnace building block normally sinters after titanium-containing blast furnace slag and other material matchings, the pretreatment process such as hot application, shrend is still needed to carry out pre-treatment to titanium-containing blast furnace slag, consume great lot of water resources, operation is numerous and diverse, and products obtained therefrom crush values is up to 17% ~ 22%.
The people such as Wang Huaibin take high-titanium blast furnace slag as main raw material, with addition of the method for shale, yellow sand, coal gangue, mineralizer sintering slag brick processed, but the high-titanium blast furnace slag that the method uses still needs to carry out the pre-treatment such as hot application, and only have 40% with addition of amount, other batching is more, and need to sinter, cost is high, complex process.
The people such as Kong Xiangwen add polystyrene emulsion, venamul, benzene emulsion 8%-20% as gelatinous material in titanium-containing blast furnace slag, are aided with additive, and oil pressure is non-burning brickly shaping.But still need in the method to add gelatinous material and additive, and the titanium-containing blast furnace slag used still needs to carry out the pre-treatment such as hot application, cost is high, complex process.
Therefore, those skilled in the art need the technique of the simpler prepared from Ti-containing blast-furnace building block of a kind of method.
Summary of the invention
Technical problem to be solved by this invention is to provide the technique of the simple prepared from Ti-containing blast-furnace building block of a kind of method.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: casting after being stirred by the liquid titanium-containing blast furnace slag after having smelted, is cooled to building block.
Adopt technique scheme, liquid titanium-containing blast furnace slag is directly poured into a mould sizing, can avoid the pretreated water consumption of hot application, meanwhile, the ultimate compression strength of gained building block is higher, and crush values is more low to moderate 10%.
Preferably, lower the temperature after liquid titanium-containing blast furnace slag ingress of air, surface hardening is lumpd, and reduces the mobility of liquid titanium-containing blast furnace slag, the liquid titanium-containing blast furnace slag heating after having smelted can be hardened to avoid surface.Contriver puts into practice discovery, stir, cast time can contact with air that causing rapidly lower the temperature harden affect pours into a mould, for avoiding this situation to occur, heat that more than titanium-containing blast furnace slag temperature to 950 DEG C effectively can delay stirring, titanium-containing blast furnace slag hardens speed when pouring into a mould.The temperature of concrete heating titanium-containing blast furnace slag is depending on the amount of titanium-containing blast furnace slag and pouring speed, and pouring speed is slow, titanium-containing blast furnace slag temperature should be higher to delay scleroma speed.Specifically titanium-containing blast furnace slag can be sent into high temperature channel heating to delay its scleroma speed.
Titanium-containing blast furnace slag divides upper, middle and lower-ranking, and wherein upper foam slag is in the majority, if do not mixed directly building block processed, gained building block quality gap can be made comparatively large, cannot satisfy the demands, therefore casting again after titanium-containing blast furnace slag can being stirred.But carry out as stirred and heating, the inflammable gas effusion be mingled with, easily causes blast accident occurs, therefore stirs and need carry out after the heating simultaneously.Liquid titanium-containing blast furnace slag extreme temperatures, conventional stirring equipment is difficult to use, easily damaged, and contriver finds, passes into gas cost lower, and can play good stirring action.Wherein, the flow of gas, air pressure without particular requirement, so that titanium-containing blast furnace slag can be made to stir, specifically depending on the amount of titanium-containing blast furnace slag.Concrete, described gas can be the regular industrial such as air, nitrogen gas.
Concrete, for ease of the demoulding, described casting can adopt detachable refractory-material dies.
High temperature channel described in the present invention can adopt existing conventional high temperature passage to carry out, can be warming up to more than 950 DEG C to titanium-containing blast furnace slag.
The present invention also provides and adopts the building block of above-mentioned technique gained.
Beneficial effect of the present invention is as follows:
1, present invention process takes full advantage of output is large, cost is low titanium-containing blast furnace slag as the raw material of building block, turns waste into wealth, protection of the environment.
2, present invention process is simple, cost is low, does not need to carry out the pre-treatment such as hot application to titanium-containing blast furnace slag, without the need to adding other raw materials, also reduces production cost.
3, present invention process produce building block fragmentation after crush values be low to moderate≤10%, the crush values 17% ~ 22% after more original prepared from Ti-containing blast-furnace building block fragmentation has obvious progress.
4, the building block that present invention process is produced can be used for wall construction, also can cut into fritter, can be used as building construction brick, and engraving building block can be made into artwork etc.
Embodiment
Below in conjunction with embodiment, the present invention is further described.But therefore protection scope of the present invention is not limited among scope of embodiments.Especially, the equipment in following embodiment, temperature are equipment and the condition control of applicant's actual production employing, and not from the limited effect, equipment and the method that can realize the object of the invention all may be used for the inventive method.
