A roller kiln system of a multilayer structure is proposed (refer to Patent Document 1). In the roller kiln of Patent Document 1, the inside of the heating furnace is divided in the vertical direction by the heat insulating wall to form a plurality of heat treatment chambers, and compared with the case where the general heating furnace is stacked in plural as a multi-stage structure, The space in the height direction suppresses the multilayer structure in a state of being in a minimum range. A method of forming a plurality of heat treatment chambers by dividing a heat insulating wall to form a plurality of heat treatment chambers, wherein the surface is placed on a support member of the furnace wall and the heat is sealed; It is also known that the maximum surface overlap of the strip-shaped heat insulating material is maintained by means of a support member that is placed on the furnace wall in the furnace. /, 疋, because the heat insulating material has the property of shrinking at a high temperature, in the above-mentioned method, in the heat treatment, through the joint of the heat insulating material and the heat insulating material, the heat insulating material and the gap of the furnace wall, The phenomenon of gas and movement between the upper furnace and the lower furnace is observed, and there is a problem that the environment in the furnace is unstable.

The novelty described in the scope of claim 2, in the multi-layer heating furnace described in the item i of the patent application, is characterized in that the heat insulating material blocks between the adjacent heat insulating layers are alternately arranged in a vertical cross section. The joint between the heat insulating material block and the furnace wall between the adjacent heat insulating layers is arranged in a vertical section.

The convex part of the furnace wall will be a strong glare π small-shaped heat-insulating brick that will be buried in the space formed between the concave portion of the heat-insulating wall and the furnace wall. It is formed by a mortar construction on the inner side surface of the furnace wall. Patent Application No. 4, Item 1 to Item 3 - The feature is that the uppermost layer of the heat insulation layer is formed by a soft cover [new effect]. In the multilayer heating furnace described above, the lowermost layer is composed of a hard sheet material covering layer. In the multi-layer heating furnace of several sections of heat treatment chamber: the composition of the second "cut: formed in the ancient, B Α古' ', the wall of the insulation material has a contraction property under the armpit, the kernel in this new type, will be separated The sill wall is composed of a support member on the furnace wall and a plurality of sections on the constituting member, ivnjy//5 No. 101204271, revised on the 27th of the next month, and the heat insulation layer is insulated. The material block is arranged side by side in the front, back, left and right. The seams between the blocks of insulating material in the adjacent layer are separated from the vertical by the joint between the block of insulating material in the adjacent layer and the wall of the furnace. The occurrence of a gap that penetrates the heat insulating wall in the vertical direction can be avoided even when the heat insulating material blocks are shrunk during the heat treatment and are generated in the gap between the heat insulating material blocks. Therefore, according to the present invention, the heat insulating material constituting the heat insulating wall at the temperature in the heat treatment can effectively suppress the gas flow between the upper furnace and the lower furnace when contracting. [Embodiment] Hereinafter, preferred embodiments of the present invention are shown. In Fig. 1, an enlarged sectional view (right half) of the multilayer heating furnace of the present embodiment in the furnace width direction is shown. In the multi-layer type heating furnace of the present embodiment, the two-layer type report t formed by dividing the inside of the furnace in the vertical direction by the heat insulating wall 7 is a structure of the furnace body 1 and a well-known (four) structure, and is internally fixed. : The pitch and a large number of rollers 2 for transport are arranged. Each of the rolls 2 is made of Si_Sic which is excellent in π / dish strength, and is driven at a constant speed by a driving device provided outside the furnace. Further, the Si_SiC-based SiC which is filled with Si has a high strength of 250 MN/m2 in 1300C. In addition, it has excellent materials for creep resistance, oxidation resistance, and infrared radiation. The powder system of the fired product is stored in a ceramic kiln 3, conveyed on the drum 2 in a state in which a plurality of kiln 3 are arranged, and heat-treated at 5 〇〇 to 12 〇〇 <> 5 ό 27 27 27 27 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 The heat insulating wall 7 is composed of a support member 8 which is placed on the furnace wall 4, and a heat insulating material block 9 which is continuously placed in a staggered manner on the support member 8. The heat insulating material block 9 is arranged side by side to form a heat insulating layer (12, 13, 14, 15). In the present embodiment, the uppermost heat insulating layer} 2 and the lowermost heat insulating layer 15 are It is composed of a hard board (b〇ard) material, and the intermediate layers 13, 14 are made of a soft bianket material. Each of the plate material and the cover material constituting the heat insulating material block 9 has a property of shrinking at a high temperature, but in the present invention, the block 9 of the adjacent heat insulating layer is alternately arranged in a vertical cross section. Since the heat insulating material block 9 shrinks during the heat treatment and a gap is formed between the heat insulating material blocks 9 between the adjacent heat insulating layers, the heat insulating wall penetrates the slit in the vertical direction (that is, A gap created by the flow of the I body between the upper furnace and the lower furnace) does not produce a structure. The size of the heat insulating material block 9 is not particularly limited, but in each of the layers 12, 13, 14, and 15, the respective constituent blocks are formed to have the same thickness, adjacent to the upper and lower layers, as the heat insulating material block 9 and The seam position of the furnace wall 4 will not be in the same position. Further, as shown in Fig. 2, in the present invention, the joint between the heat insulating material block 9 and the furnace wall 4 between the adjacent barrier layers is arranged in a vertical cross section, so that it is a long time in the heat treatment. Each of the heat insulating material blocks shrinks, and the joint position between the heat insulating material block and the furnace wall creates a structure in which the gap wind horse does not generate a gap between the partition wall 5 and the furnace wall in the vertical direction. It is effective in the case where the heat-insulating material of the heat-insulating wall of the heat-retaining wall of the heat-removing wall of the fourth page 204271 of the revised date of the modification of the M439775 on June 27, 2011 The gas flow between the upper furnace and the lower furnace is suppressed. In the present embodiment, the furnace wall 4 is composed of heat-insulating bricks, and the convex portion 11 of the furnace wall 4 is a partition of a space which is buried between the concave portion 1 of the heat insulating wall 7 and the furnace wall 4. The hot brick is formed by applying a smear on the inner side of the furnace wall (f 1 at ), but the forming means of the convex portion u is not particularly limited. Further, the furnace wall 4 may be composed of fireproof bricks. • [Simplified description of the drawing] The expansion of the expansion portion of the furnace width direction of the furnace is shown in Fig. 1 as a multi-layered teaching large cross-sectional view (right half) of the present embodiment; and FIG. 2 is a heat insulating material block.
