Description
Technical field
The present invention relates to constructional materials and preparing technical field thereof, more particularly, relate to a kind of sintered hollow block and preparation method thereof.
Background technology
Hollow brick is a building trade materials for wall commonly used in recent years, because advantage such as light weight, consumption of raw material be few has become the product that national construction sector is at first recommended.Development hollw article (mainly being hollow brick) is the main path of China's development novel wall material.Use the hollow brick province's soil that not only can save land, energy conservation, simultaneously because hollow brick has light weight, high-strength character, thus the deadweight of using hollow brick can alleviate building masonry wall in a large number, thus construction cost can be reduced significantly.
High-titanium blast furnace slag is through comprising that carrying of processes such as high temperature cabonization, low temperature chlorination can a large amount of residue of residue after the titanium PROCESS FOR TREATMENT.Because SiO in this residue
2Content is lower, TiO
2, CaO, MgO content be higher, is difficult to realize effective recycling, so the main methods that this class residue is taked is to stack at present.At China's Panxi Diqu, because prior art can not realize the making full use of of v-ti magnetite ore resources produced a large amount of above-mentioned residues.Climbed the steel titanium-containing blast furnace slag by 2007 and totally discharge more than 5,000 ten thousand tons, and still stack with 3,000,000 tons/year speed continuation, this type of titanium-containing blast furnace slag will remain about 80% low titaniferous residue after putting forward the titanium PROCESS FOR TREATMENT.The stacking severe contamination of these titanium-containing blast furnace slags and titaniferous residue ecological environment, and a large amount of land occupation, and hindered Sustainable Development of Enterprises is so be badly in need of seeking suitable pathways at present to realize the utilization again of carrying the titanium residue of high-titanium blast furnace slag.
Chinese patent CN101333087 disclose a kind of produce floor tile, kerb, exterior wall tile and watt batching, its raw material is made up of following component by weight: red shale 33～60, vanadium titanium slag 10～20, flyash 7～20, silica sand 5～15, clay 5～12 has been realized the utilization to the vanadium titanium slag.Document " utilization is climbed the steel chloride residue and produced low-clinker cement ", " approach of steel titanium ore slag is climbed in the high value comprehensive utilization " have been introduced and have been utilized chloride residue to produce complex cement and low-clinker cement method.Yet, do not find to utilize to propose the relevant record that the titanium residue prepares sintered hollow block.
Summary of the invention
At the problems referred to above, the invention provides a kind of carry titanium residue and shale with high-titanium blast furnace slag is the method that raw material is made sintered hollow block, try hard to solve the problem of environmental pollution that stacking caused of carrying the titanium residue, and realize putting forward the second use of titanium residue because of high-titanium blast furnace slag.
An aspect of of the present present invention provides a kind of sintered hollow block, comprises shale and titaniferous residue; Wherein, the percentage by weight of described titaniferous residue is 1%～50%, and the percentage by weight of described shale is 50%～99%.

According to sintered hollow block of the present invention, wherein, what described titaniferous residue can be for high-titanium blast furnace slag carries the titanium residue.
Another aspect of the present invention provides a kind of method of making sintered hollow block, said method comprising the steps of: with percentage by weight is that 1%～50% titaniferous residue and percentage by weight are that 50%～99% shale mixes, in mixed material, add water and stir, to form mixed material; The described mixed material of ageing; Treat mixed material after the ageing reach the required moisture of moulding and homogenizing fully after, extrusion molding is to form blank, wherein, the required moisture of mixed material moulding is meant that the mixed material moisture content is 13%～19%; Described blank is cut into adobe, and dry described adobe; The dried adobe of roasting.
According to the method for making sintered hollow block of the present invention, wherein, described titaniferous residue and described shale can be finely ground to particle diameter less than 0.5mm.
According to the method for making sintered hollow block of the present invention, wherein, what described titaniferous residue can be for high-titanium blast furnace slag carries the titanium residue.
According to the method for making sintered hollow block of the present invention, wherein, the time of the described mixed material of ageing can be 48～72 hours.
According to the method for making sintered hollow block of the present invention, wherein, the temperature that dry described adobe is adopted can be 95～105 ℃, and can be 20～30 hours drying time;
According to the method for making sintered hollow block of the present invention, wherein, the temperature that the dried adobe of roasting is adopted can be 920～1100 ℃, and roasting time can be 30～45 hours.
Proposed by the invention with high-titanium blast furnace slag carry the titanium residue and shale is sintered hollow block of raw material and preparation method thereof; project investment is low, production technology is simple; and can realize high-titanium blast furnace slag carry the titanium residue (hereinafter; abbreviate as and carry the titanium residue) second use; making it turns waste into wealth, turns bane into boon, to economizing on resources, protect environment significant.
The specific embodiment
Sintered hollow block according to an aspect of the present invention comprises shale and titaniferous residue; Wherein, the percentage by weight of described titaniferous residue is 1%～50%, and the percentage by weight of described shale is 50%～99%.
The method of making sintered hollow block according to a further aspect in the invention, can realize by following manufacture craft:
A, raw material is mixed by proportioning, add water and stir.
B, the mixed material that stirs in (a) step was sent into the ageing of ageing storehouse 48～72 hours.In ageing process,, can make the further refinement of mixed material and impel moisture distribution even, thereby improve the index of plasticity of compound to a certain extent through the infiltration of water to mixed material.
C, the mixed material after the ageing is measured, and add the water stirring, (at this, homogenizing fully is meant fully mixes mixed material to reach the abundant back of required moisture of moulding and homogenizing, so that each component evenly distributes in the mixed material), through the vacuum-extruder extrusion molding.
D, described blank is cut into adobe, and dry brick, the temperature that dry brick adopted can be 95～105 ℃, can be 20～30 hours drying time.At this, if baking temperature is low excessively, then moisture is difficult for evaporation, thereby causes long and dry back residual moisture height drying time, influences product quality; If baking temperature is too high, then easily produce defective in the dry materials process, also can influence product quality.
