Abstract
The invention discloses high-temperature-resistant honeycomb briquette. The high-temperature-resistant honeycomb briquette is prepared from pulverized coal and sintering maintaining agents, the mass ratio of the pulverized coal to the sintering retaining agents is 100: 20-50, the sintering retaining agents are clay or kaolin containing aluminum oxide, and the sintering retaining agents are adjusted according to the content of aluminum oxide. The honeycomb briquette can have good shrinkage retainability and does not melt due to high temperature in the heating and calcining process, and calcined product pollution or furnace smelting due to fusion of honeycomb briquette in the calcining process can be avoided.
Description
Technical field
The present invention relates to fuel technology field, particularly relate to a kind of resistant to elevated temperatures honeycomb briquette.
Background technology
Honeycomb briquette is a kind of fuel with low cost, makes main raw material with bituminous coal and hard coal etc.Honeycomb briquette raw material is extensive, with low cost, easy to use, it is simple to make, can reach that material-saving saves time, the object of saving energy and cost.Traditional honeycomb briquette is by raw coal and clay mixing and water adding is shaping makes, and clay mainly plays shaping effect, and the ratio of raw coal and clay is generally about 100:20-50, when calcination of talc or kaolin, generally first be pressed into brick, burn till with annular kiln or tunnel furnace, available cellular coal is as fuel.With reference to figure 1, adobe 1 and honeycomb briquette 2 are piled up layer by layer and fires in kiln, because burned product calcining temperature is up to 1100-1400 DEG C, in high-temperature firing process, unselected clay (usually gathering materials on the spot) is generally used to make tackiness agent owing to making honeycomb briquette, clay component is calcium mainly, iron, silicon, the hopcalite of magnesium, very low containing aluminium sesquioxide, in stove or when kiln temperature reaches more than 950 degree, just easily fusing, the easy melting of honeycomb briquette produces flow-like melt substance 3 and trickles to the surface of brick goods, after the calcining of brick goods, flow-like material just can strong bond at the outside surface of brick body, thus easily have influence on outward appearance and the color of goods, if by artificial powerful these melt substances of removing, not only waste time and energy, but also the breakage of brick body can be caused, affect quality product, increase production cost.This problem is also a difficult problem for high quality tile product manufacturing and processing enterprise always.
The mineral composition of coal and structural form have material impact to its meltbility, how to improve the high temperature resistant meltbility of coal, and keep and control coal high-temp combustion time melting characteristic, avoid its heating and calcining process fluidly shape as far as possible, avoid melt substance in brick body sintering process to trickle to brick surface, to tile product, manufacturer has great importance.
Chinese invention patent CN1051582A discloses a kind of processing method making easy-to-burn honeycomb briquet, adopt the mixture base-materials such as raw coal, carbonization wood sawdust, lime, red soil, wood charcoal powder and be made up of the inflammable ignition dope such as nitrate, potassium permanganate, although the inflammableness of improve, but its material composition is complicated, production cost is higher, and does not still overcome the problem that fluid appears in the easy melting of high temperature.
Summary of the invention
Technical problem to be solved by this invention is to provide in a kind of heating and calcining process can have good contraction retentivity, not easily occur outflow flowing material, and the external sight of brick in refractory brick sintering process can be avoided to be subject to the resistant to elevated temperatures honeycomb briquette of melt substance pollution.
For solving the problems of the technologies described above, technical scheme of the present invention is: resistant to elevated temperatures honeycomb briquette, and for calcining goods in kiln, comprise coal dust and sintering retention agent, the mass ratio of described coal dust and described sintering retention agent is 100:20-50;
Wherein, described sintering retention agent is the clay or the kaolin that contain aluminium sesquioxide.
As preferably, also comprise clay, the mass content of described sintering retention agent is the 10-100% of described clay quality.
During concrete use, can according to the consumption of kiln calcining temperature adjustment sintering retention agent.
When kiln temperature be 950 degree-1000 spend time, the mass content of described sintering retention agent is the 10-30% of described clay quality.
When kiln temperature be 1000 degree-1100 spend time, the mass content of described sintering retention agent is the 30-40% of described clay quality.
When kiln temperature be 1100 degree-1150 spend time, the mass content of described sintering retention agent is the 40-50% of described clay quality.
When kiln temperature be 1150 degree-1200 spend time, the mass content of described sintering retention agent is the 50-60% of described clay quality.
When kiln temperature be 1200 degree-1250 spend time, the mass content of described sintering retention agent is the 60-70% of described clay quality.
When kiln temperature be 1250 degree-1300 spend time, the mass content of described sintering retention agent is the 70-80% of described clay quality.
When kiln temperature be 1300 degree-1350 spend time, the mass content of described sintering retention agent is the 80-90% of described clay quality.
When kiln temperature be 1350 degree-1400 spend time, the mass content of described sintering retention agent is the 90-100% of described clay quality.
As preferably, described containing AL in the clay of aluminium sesquioxide
2o
3mass content be 30%-35%.
As preferably, described containing AL in the clay of aluminium sesquioxide
2o
3mass content be 35%-40%.
Owing to have employed technique scheme, the present invention has following beneficial effect: by adopting containing aluminium clay or kaolin as sintering retention agent, because these sintering retention agents are in heating and calcining process, there is high viscosity and good contraction, sintering maintenance effect, after reaching certain temperature, carbon in honeycomb briquette, volatile matter, moisture starts reduce and make volumetric shrinkage, but due to containing a certain amount of aluminium sesquioxide composition, fluidly shape can be avoided in its heating and calcining process, melt substance in brick body sintering process is avoided to trickle to brick surface, be beneficial to the visual appearance improving tile product, reduce finished product impurity.
