Abstract
The invention discloses a microwave drying method of corundum composite ceramic material, and the method comprises the following steps: placing the moulded blankof corundum composite ceramic material into a microwave drying room, carrying out microwave drying with an industrial microwave source whose frequency is 2.45GHz+-25MHz, gradually heating to 60 DEG C from normal temperature, performing heat preservation for one hour, heating to 1100 DEG C, performing heat preservation for 3 hours, and then naturally cooling to room temperature. According to the invention, the uniformity of the drying methodis substantially improved than the uniformity of the conventional drying, and the drying time is substantially shortened; compared with the conventional drying method, the non-contact microwave drying method can avoid impurity pollution in the drying process.
Description
Technical field
The present invention relates to technical field of refractory materials, specifically a kind of corundum composite ceramic material method for microwave drying.
Background technology
Corundum composite ceramic material has high temperature resistant, and heat-shock resistance is excellent, and wear resistance is good, and intensity is high, good toughness, creep resistance and resistance to fouling is good and Young's modulus high, is specially adapted to hold burn soft magnetism (ferrite) material and electronic isolation is ceramic.Corundum composite ceramic material manufacture craft generally includes batching-batch mixing-shaping-dry-fire.At present, the drying of corundum composite ceramic material mainly adopts melt pit drying or electric seasoning, be utilize combustion fuel or resistance heating element indirec radiation heating, the dry cycle is long, adopts melt pit drying to need 10-20 days, electric seasoning is adopted also to need 2-3 days, and energy consumption is large, efficiency is low, meanwhile, drying process is internally slowly spread by the surface of product, inside and outside degree of drying lack of homogeneity, for the parts that thickness is larger easily cause external and internal compositions and performance uneven.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, provide a kind of time of drying short, dry evenly, the corundum composite ceramic material method for microwave drying of better effects if.
The technical solution used in the present invention is as follows, described corundum composite ceramic material method for microwave drying is: be placed in microwave drying room by the corundum composite ceramic material blank of forming, employing frequency is that microwave drying is carried out in the industrial microwave source of 2.45GHz ± 25MHz, temperature is warming up to 60 DEG C gradually by normal temperature, be incubated 1 hour, then temperature is risen to 1100 DEG C, be incubated 3 hours, then naturally cool to room temperature.
Adopt corundum composite ceramic material method for microwave drying provided by the invention, the homogeneity of product drying improves greatly than conventional drying, time of drying shortens greatly, and compared with conventional drying, the contactless drying of microwave can also avoid the contaminating impurity in drying process.
Embodiment
Below in conjunction with embodiment, the present invention is described in more detail.
Be placed in microwave drying room by the corundum-mullite push pedal blank of forming, employing frequency is that microwave drying is carried out in the industrial microwave source of 2.45GHz, and temperature is warming up to 60 DEG C gradually by normal temperature, be incubated 1 hour, then temperature is risen to 1100 DEG C, be incubated 3 hours, then naturally cool to room temperature.
Personnel in the art should be realized that, above-described embodiment is not used as limitation of the invention, as long as in spirit of the present invention, anyly all do not exceed protection scope of the present invention to above-described embodiment technique variation, deformation program.
