Abstract

PURPOSE:To provide a baking bogie in which it has a low heat accumulation amount and there is no possibility of producing any cut or crack at its outer frame part even if a thermal shock is applied to the bogie. CONSTITUTION:An outer frame of a car top 3 is constructed by a plate member 4 having a thickness of 10 mm or less and made of a ceramic baked member such as Si-SiC or the like and then a light weight thermal insulation material 7 is filled inside the plate member 4. With such an arrangement as above, it is possible to make a light weight bogie, and so cut or crack may not be produced due to the fact that the plate made of a ceramic sintered material such as Si-SiC or the like.

2. Description of the Related Art Carts for firing ceramic products as described above are
A refractory car top is provided on top of a metal frame equipped with wheels for traveling. FIG. 3 is a cross-sectional view showing a typical example of such a conventional truck for firing, 11 is a wheel,
Reference numeral 12 is a metal frame, and 13 is a refractory block forming the outer periphery of the car top.

The outer peripheral portion of the car top is a portion which is easily contacted by an operator when loading or unloading a product onto or from a trolley, and is required to have a strength that does not easily deform. Further, since it is a portion that is strongly heated by the burner when traveling inside the tunnel furnace, heat resistance and heat insulation are required. Furthermore, stability as a structure is required. In order to satisfy these requirements, conventionally, as shown in FIG. 3, a large refractory block 13 is installed on the outer periphery of the car top, and a heat insulating brick or a lightweight heat insulating material 14 is provided inside the block.

However, the refractory block 13 is a large-weight block in order to have stability so that it does not fall outside during the traveling of the bogie, and therefore the heat storage amount thereof becomes very large. For this reason, the amount of heat taken out when the trolley for firing goes out of the firing furnace becomes large, which causes a large heat loss. Also such a large refractory block
Since it is not easy to manufacture 13 as a whole homogeneously, there is a risk of partial chipping or cracking when it is subjected to thermal shock.

FIG. 2 is a sectional view of the essential parts showing a second embodiment of the present invention. In this embodiment, a plate material 4 made of a Si-SiC sintered body having an L-shaped cross section, which constitutes the outer frame of the car top 3, is joined midway, but the other points are the same as the first embodiment. There is no difference. The Si-SiC sintered bodies can be easily bonded to each other as in this embodiment. It can also be mechanically fixed with bolts or the like.

The firing cart of the embodiment thus constructed has a structure in which the outer frame of the car top 3 is constituted by a plate material 4 made of a Si-SiC sintered body, and a light weight heat insulating material 7 is filled inside thereof. Therefore, unlike the conventional one using a heavy refractory block, the weight of the car top 3 can be significantly reduced. For this reason, the heat storage amount of the truck can be reduced, and the amount of heat taken out by the firing truck is also reduced, so that heat loss can be reduced. Moreover, Si-SiC
Since the plate member 4 made of a sintered body is excellent in strength, there is no risk of deformation even when a worker comes into contact with the product when loading or unloading the product onto or from the cart.

Since the plate material 4 made of the Si-SiC sintered body is excellent in heat resistance and thermal shock resistance, the firing truck of the present invention uses the conventional heavy-weight refractory block in these respects. It is not inferior to the firing truck that was used. Moreover, since the plate material 4 made of the Si-SiC sintered body can be extruded or press-molded, it is possible to manufacture an extremely homogeneous plate material 4, which is subjected to thermal shock like a conventional heavy-weight refractory block. Sometimes it does not chip or crack.
