Abstract
The invention relates to a processing technology for a special refractory material binder. According to the invention, imported gamma-alumina and high purity limestone are taken as the raw materials, an organic dispersant is added, so that the product has the advantages of high purity, stable quality and good fireproof performance. According to the invention, the raw material employs a continuous ball forming mill, thereby the problem of difficult realization of automation moulding of raw material by a semi-dry process and a wet method can be solved.
Description
Technical field:
The present invention relates to the complete processing of a kind of complete processing of special refractory wedding agent, particularly a kind of high-purity aluminous cement.
Background technology
High-purity aluminous cement early epistasis can be good, and the remaining intensity of middle temperature is high, 650 ℃ of refractoriness high (〉 l), as with W (A1 in the cement
2O
3) bring up to 80%, refractoriness can reach 790 ℃ of l, and wear-resisting, and antistripping, resistance to reduction erosion medium resistance ability are strong, are suitable as agglutinate or are formulated in the unshape refractory that uses under high temperature, high pressure and the reductive condition.
The manufacturer of most of high-purity aluminous cement all produces with the electric smelting method both at home and abroad at present, and production cost is high, and difficulty is larger, although some also is the sintering process that adopts, calciner all adopts shuttle kiln or rotary kiln to burn till.Shuttle kiln belongs to periodic kilns the kiln, and its throughput is low, and energy dissipation is serious; And the initial cost of rotary kiln is large, and weight of equipment is large, and floor space is larger, and the waste gas dustiness of rotary kiln is larger in addition, needs the supporting high temperature resistant equipment that gathers dust, and raw material and the fuel of unit product are more.
Summary of the invention:
The invention provides a kind of commercial alumina and high-purity Wingdale take gama-alumina as principal crystalline phase and be raw material, the complete processing of the high-purity aluminous cement of direct production.
Technical scheme of the present invention is: the commercial alumina take gama-alumina as main crystalline phase and high-purity Wingdale are raw material, the Al of commercial alumina
2O
3Content＞98.5%, the principal constituent of high-purity Wingdale are CaO, then according to the following steps processing:
1), by weight percentage, high-purity Wingdale of 50%-70% commercial alumina and 30%-50% is made compound, in compound, drop into dispersion agent by weight 0.01%-0.05%, stir, then send into the fine grinding equipment and carry out extra-fine grinding, being milled to fineness d50 is the 1-10 micron;
2), finer abrasive, water, wedding agent are evenly added the continous way nodulizer and make the ball base; The weight ratio of finer abrasive, water, dispersion agent is 70-90:10-30:0.5-3.5;
3), with ball base oven dry, the ball base after the oven dry drops into the shaft furnace calcining, is warmed to 1350 ℃-1500 ℃, the time is 10-24 hour;
4), product pick, fragmentation, grinding, deironing, packing makes.
Described abrasive machining apparatus is vibration mill, ball milling, stirring mill.
Described dispersion agent is triethanolamine, ethylene glycol, sodium polyphosphate, stearic composite dispersing agent.
It is raw material that the present invention adopts import gama-alumina and high-purity Wingdale, is equipped with organic dispersing agent, so that product purity is high, steady quality, fire performance are good; Material forming of the present invention partly adopts the continous way nodulizer, has solved semidrying, the difficult problem that realizes automatization of wet method material forming.
