As shown in the figure, from one side of the tunnel furnace 1, the base plate 3 on the track 2 and the object to be heated 4 placed on the base plate 3 are pressed by the pusher 5 as shown by the arrow a. A firing apparatus is known that burns out organic substances such as binders contained in the object to be heated 4 by passing the object through a tunnel furnace 1 and then heats and sinteres the object. The tunnel furnace 1 has an outer wall 101 made of a heat insulating material, and the inside thereof is filled with a refractory brick layer 103 partitioned by pinewood boards 102, and a resistance heating element 104 is attached inside the refractory brick layer 103. It has a structure. 6 is a pedestal.

るという欠点があつた。 However, in the past, it was common to use a heat-resistant material strong enough to withstand the firing temperature of the base plate 3 and the pressing force of the pusher 5, such as carborundum or mullite . It is necessary to gradually raise the temperature from the temperature to the firing temperature Tp, which increases the time required to reach the stable zone B, resulting in a disadvantage that the firing process takes a long time.
そこで本考案は、トンネル炉等の焼成炉を使用

置用台板を提供することを目的とする。 Therefore, when firing using a firing furnace such as a tunnel furnace, the present invention is designed to shorten the heating time of the heated object by combining it with a high-frequency heating device, making it possible to significantly shorten the firing time compared to conventional methods. The object of the present invention is to provide a base plate for a firing device that has a high temperature.

したもの等を挙げることができる。 That is, the base plate on which the object to be heated is placed and transported into a firing furnace such as a tunnel furnace was conventionally made of a heat-resistant material such as carborundum or mullite, but in the present invention, it is made of a heat-resistant material such as carborundum or mullite. Consists of items that generate heat loss. Specific examples include carborundum or mullite mixed with ferrite powder.

ンネル炉１の入口側の下方に設けてある。 FIG. 3 is a diagram showing an embodiment of the firing apparatus for firing using the base plate according to the present invention. In the figures, the same reference numerals as in FIG. 1 indicate the same components. As mentioned above, the base plate 3 is made of a material that generates high-frequency loss heat, such as carborundum or mullite mixed with ferrite powder. Further, as a means for generating high-frequency loss heat generation in the base plate 3, a high-frequency heating device 7 is provided near the conveyance port of the heated object of the tunnel furnace 1. In this embodiment, the high frequency heating device 7 is provided below the entrance side of the tunnel furnace 1.

となる。 In the above firing apparatus, when the base plate 3 on which the object to be heated 4 is placed is pushed in the direction of the arrow a by the pusher 5 and transported into the tunnel furnace 1 while the high-frequency heating device 7 is driven, the When passing over the high-frequency heating device 7 installed nearby, high-frequency loss heat generation occurs in the base plate 3 due to eddy current, and the base plate 3 and the heated object 4 on it are preheated by this high-frequency loss heat generation. Ru. For this reason, the firing time-temperature characteristics of the firing apparatus using the base plate 3 according to the present invention, as shown as characteristic L1 in FIG. The temperature increase rate in step (a) becomes faster, and the firing process is shortened accordingly.

である。 Furthermore, the base plate 3 can be made by simply mixing ferrite or the like with conventional carborundum or mullite, and high frequency loss can be generated without impairing the necessary mechanical strength and heat resistance. In addition, the conventional baking device can be used as is by simply adding the high-frequency heating device 7, so it is easy to implement.
