［産業上の利用分野］
本考案は溶融アルミニウム合金を圧送する配湯
管に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a hot water distribution pipe for conveying molten aluminum alloy under pressure.

る構成をとつている。[Prior Art] A conventional technology will be explained with reference to FIG. A hollow circular ceramic pipe 23 made by molding and firing ceramics is used as the hot water distribution pipe 21.
Cracks occur due to repeated cooling, etc., and the molten metal begins to leak. In order to prevent rapid growth of leakage of molten metal, a structure is generally adopted in which ceramic paper 22 is wrapped around the outer periphery of the ceramic tube 23 and held down with a wire 24.

案は従来技術のセラミツクスペーパ部分での溶湯
の浸透を防いで寿命を延ばした配湯管を提供する
ものである。[Problems to be solved by the invention] However, since the ceramic paper in the above structure is porous and the voids formed between the surfaces of the rolled layers cannot be removed, it is impossible to prevent the molten metal from seeping out. Its ability is limited to reducing the force of molten metal leaking from the pipes. The present invention provides a hot water distribution pipe that has a longer service life by preventing penetration of molten metal through the ceramic paper portion of the prior art.

と共に焼成する。[Means for Solving the Problems] The hot water distribution pipe of the present invention is formed by molding and firing molten metal resistant ceramic into a tubular shape.
Ceramic paper, which is made by molding ceramic fiber into a porous paper shape, is impregnated with a molten metal resistant adhesive and wound in multiple layers around the outer periphery of the ceramic tube to form a dried ceramic paper layer, which is then fired together with the ceramic tube.

湯管の機能を維持する。[Operation] Even if a crack occurs in the ceramic tube, the crack does not extend to the ceramic paper layer covering the ceramic tube. In addition, in the ceramic paper layer, the pores in the ceramic paper and the gaps between the paper surfaces are filled with a molten metal resistant adhesive, so that the molten metal that seeps out from the cracks in the ceramic pipe will not leak outside, even after the end of the life of the ceramic pipe. Maintain the functionality of hot water pipes.

A paper made of ceramic fibers such as iO 2 formed to a thickness of about 0.5 to 2 mm is impregnated with an adhesive, wrapped in multiple layers around the outer periphery of the ceramic tube 3, dried, and fired together with the ceramic tube.

寿命を助長する効果を奏する。[Effects of the invention] As mentioned above, the hot water distribution pipe of the present invention is made by wrapping ceramic paper impregnated with adhesive in multiple layers while adhering it to the outer periphery of the main body of the ceramic pipe, which prevents cracks from occurring in the ceramic pipe. Since the molten metal does not immediately leak out to the outside, it has the effect of prolonging the service life of the molten metal pipes.
