よつて得られる。Conventional technology Conventionally, the third pipe was used as a transport pipe for molten aluminum.
The one shown in Fig. 4 and Fig. 4 is used. In other words, the position is the steel pipe body, 2 is the flange,
3 is a tubular lining layer made of ceramic fiber, and this lining layer is made of a tubular ceramic fiber molded product and adhered to the inner surface of the tube with an inorganic adhesive, or by preparing a pouring material containing ceramic fiber, It is obtained by pouring and molding between a tube and a mold provided concentrically with the tube.

り摩耗することなどから寿命が短かい。Problems to be solved by the invention According to the above-mentioned transport pipe for molten aluminum, the ceramic fiber layer that is the lining layer 3 works effectively as a heat insulating layer to prevent the temperature of the hot water from decreasing, but the ceramic fiber layer has a large number of pores. Due to factors such as the fact that the ceramic fiber layer and the molten aluminum react at the contact point, the molten metal penetrates or adheres, resulting in many blockage accidents, and the ceramic fiber layer is abraded due to heating or the flow of the molten metal. Due to these reasons, it has a short lifespan.

によつて固着された構造からなるものである。Means and Effects for Solving the Problem In order to solve the above-mentioned problems, this invention has an outer tube made of a metal tube body and an inner tube made of a silicon nitride ceramic tube in an annular space formed between the two tubes. It consists of a structure secured by a layer of pouring material containing injected ceramic fibers.
前記内管に用いた窒化珪素セラミツクスは、熱

に顕著な効果を得ることができる。 The silicon nitride ceramic used for the inner tube has a small coefficient of thermal expansion and high heat spalling resistance.
It has high strength and excellent abrasion resistance, which not only greatly improves the durability of transport pipes, but also has physical properties that prevent molten aluminum from adhering to and penetrating, reducing the risk of transport pipe blockage accidents. A remarkable effect can be obtained in prevention.

It consists of a structure fixed by a layer of fiber-containing pouring material, so
Excellent wear resistance against molten metal, and prevents molten metal from adhering to
It is difficult to penetrate and is effective in preventing blockage accidents.In addition, the flexibility of the ceramic fiber lining layer, which has excellent heat insulation effects, absorbs the thermal expansion of the silicon nitride ceramic inner tube, preventing breakage due to thermal stress. A molten metal transport pipe that is also effective in preventing destruction due to mechanical impact can be obtained.
