Embodiment 1
[0063] Present embodiment handles the newly purchased setter plate according to the following method:
[0064] (1) Place a column on the four corners of the rectangular setter plate respectively, the column is a cube with a side length of 8mm, and then stack another setter plate on the column, and repeat the above-mentioned placing column and stacking The operation of firing boards is to obtain a stack of setter boards, the number of stacked layers of setter boards in the stack of setter boards is 10 layers, and the number of stacks of the stack of setter boards is 10 stacks;
[0065] (2) In the kiln, the setter stack described in step (1) is heated to 25°C to 200°C→6h to 500°C→6h to 800°C→3h to 950°C, Empty plate sintering was carried out at 950°C. The sintering time of the empty plate was 1.5 h. No ferrite sheet was placed on the setter plate. After cooling, the empty plate sintering was repeated 3 times to obtain the sintered setter. burning board;
[0066] (3) The setter...
Embodiment 2
[0074] Present embodiment handles the newly purchased setter plate according to the following method:
[0075] (1) Place a column on the four corners of the rectangular setter plate respectively, the column is a cube with a side length of 5mm, and then stack another setter plate on the column, and repeat the above-mentioned placing column and stacking. The operation of burning boards is to obtain a stack of setters, the number of stacked layers of the setters in the stack of setters is 2 layers, and the number of stacks of the stacks of setters is 4 stacks;
[0076] (2) In the kiln, the setter stack described in step (1) is heated to 200°C → 4h to 500°C → 4h to 800°C → 2h to 1000°C. Carry out empty plate sintering at 1000°C, the empty plate sintering time is 1h, no ferrite sheet is placed on the setter plate, after cooling, repeat the empty plate sintering twice to obtain the sintered setter plate;
[0077](3) The setter plate described in step (2) is taken out from the kiln...
Embodiment 3
[0085] Present embodiment handles the newly purchased setter plate according to the following method:
[0086] (1) Place a column on the four corners of the rectangular setter plate respectively, the column is a cube with a side length of 10mm, and then stack another setter plate on the column, and repeat the above-mentioned placing column and stacking The operation of firing boards obtains a stack of setters, the number of stacked layers of the setters in the stack is 13, and the number of stacks of the stacks of setters is 24;
[0087] (2) In the kiln, the setter stack described in step (1) is heated to 200°C → 8h to 500°C → 8h to 800°C → 4h to heat up to 900°C, Empty plate sintering was carried out at 900°C. The empty plate sintering time was 2 hours. No ferrite sheet was placed on the setter plate. After cooling, the empty plate sintering was repeated 4 times to obtain a sintered setter. plate;
[0088] (3) The setter plate described in step (2) is taken out from the kil...
