[0012] The preparation method comprises the following steps:
[0013] (1) Mixing: put all the raw materials into the mixing machine according to the ratio of raw materials and mix them evenly;
[0014] (2) Trapped material: put the uniformly mixed material in step (1) in a closed state for 12-36 hours;
[0015] (3) Molding: put the materials that have been left still in step (2) into corresponding molds after weighing according to the materials required by different kiln furniture; during molding, the mold is vibrated and pressurized on both sides, and the extreme vibration force is 200-350KN, vibration time 1-30 seconds;
[0016] (4) Drying: drying the blank formed in step (3) at 80-120°C until the water content is less than 1%;
[0017] (5) Firing: sintering and forming at 1300-1650° C. to obtain the complex-phase high-temperature-resistant kiln furniture.
[0018] (6) Detection: The composite kiln furniture fired in the step (5) is tested according to the technical requi...

[0021] The production process of kiln furniture is:
[0022] (1) Mixing: Put the raw materials into the mixer according to the above ratio and mix them evenly; if 1000Kg of materials are configured, the weight of each material is as follows:
[0023] SiC 900Kg, Si 2 ON 2 and Al 2 TiO 5 Mix according to the ratio of 1:1 to reach a total amount of 98Kg, and the room temperature binder is 2Kg. Among the above 900Kg SiC, 500Kg of SiC particles with a particle size of 20 mesh, 400Kg of SiC fine powder with a particle size of 200 mesh, and the above 98Kg of SiC 2 ON 2 and Al 2 TiO 5 It is a fine powder of 7 μm, and the above-mentioned binder at room temperature is dextrin.
[0024] (2) Trapped material: the above-mentioned uniformly mixed material was left to stand in a closed state for 24 hours;
[0025] (3) Molding: The prepared materials are weighed according to the materials required by different kiln furniture and put into the corresponding molds for molding; during mo...

[0032] The production process of kiln furniture is:
[0033] (1) Mixing: Put the raw materials into the mixer according to the above ratio and mix them evenly; if 1000Kg of materials are configured, the weight of each material is as follows:
[0034] SiC 850Kg, Si 3 N 4 and Al 2 TiO 5 Mix according to the ratio of 1:1 to reach a total amount of 148Kg, and the normal temperature binder is 2Kg. Among the above-mentioned 850Kg SiC, 500Kg of SiC particles with a particle size of 20 mesh, 350Kg of SiC fine powder with a particle size of 200 mesh, and the above-mentioned 148Kg of SiC 3 N 4 and Al 2 TiO 5 7μm fine powder. The above-mentioned binder at room temperature is a polyvinyl alcohol PVA solution with a concentration of 10%.
[0035] (2) Trapped material: the above-mentioned uniformly mixed material was left to stand in a closed state for 24 hours;
[0036](3) Molding: The prepared materials are weighed according to the materials required by different kiln furniture ...
