The white jade corundum bricks 13 here are stacked together vertically, and the white jade corundum bricks 12 are placed on the oxidation furnace platform, and the tops of two of the white jade corundum bricks 13 are placed with silicon carbide bracket tooling 14, using CVD SIC is consistent with the material of the product, which can avoid product defects caused by tooling problems. The same material will not affect its thermal conductivity, and the contact end of the product and the tooling can also be heated evenly. At the same time, the surface is polished into a smooth curved surface with a certain curvature to avoid the risk of scratching the product with sharp edges during placement. Grooves with a length of 10MM, a depth of 5MM, and an interval of 50MM are also opened on the curved surface. These grooves can place the product stably on the tooling to avoid the product from shaking in the furnace or even colliding. At the same time, the number of products operating in the oxidation furnace at the same time can also be limited to ensure the product yield. The upper end of the silicon carbide bracket tooling 14 is an arc, which can effectively avoid the collapse and breakage of the inner diameter of the product due to contact with edges during the firing process, thereby improving the product yield. A plurality of circular grooves 15 are opened on the top of the silicon carbide bracket tooling 14, and the top of the lower furnace body 1 is fixedly connected to the upper furnace body 18, and the inner wall of the upper furnace body 18 is fixedly connected to the furnace cavity 17.

[0038] If the product is small, place two white jade corundum bricks 13 horizontally, and mount the silicon carbide support fixture 14 on the top of the two white jade corundum bricks 13, so that the diameter of the object that the device can bear becomes shorter, and the firing is carried out in the same way as above.

[0039] Compared with some devices in the prior art, the above content uses multiple white jade corundum bricks 13 in different placement methods to change the stacking placement into a hanging placement, and opens a circular groove 15 on the silicon carbide support tooling 14 to increase the contact area of the product. When multiple products need to be processed, the product yield is increased.
[0040] Working principle: white jade corundum brick 13 is placed on the oxidation furnace platform, and the placement method of silicon carbide bracket tooling 14 is determined according to the size of the product. When the diameter of the product is too large, it can be erected, and silicon carbide bracket tooling 14 is placed on both sides, and then silicon carbide bracket tooling 14 is placed on silicon carbide bracket tooling 14. The position is adjusted so that silicon carbide bracket tooling 14 can be placed stably on white jade corundum brick 13, and then the product is placed in the groove of silicon carbide bracket tooling 14, and the inner diameter of the product is selected to contact silicon carbide bracket tooling 14.
