However, in the case of such a conventional technique, especially in the latter case, the heat-generating portion of the heater is exposed on the surface of the molten metal, and the temperature of the protective tube at that portion becomes high, so that the molten metal adhered to the outer peripheral surface is oxidized and solidified (for example, corundum). However, due to the difference in the coefficient of thermal expansion from the solidified layer, the protective tube is likely to be damaged, resulting in a short heater life and inferior heat transfer efficiency to the molten metal.

On the other hand, in order to overcome the problems of the above-described molten metal holding furnace and the immersion heater used therein, in Japanese Utility Model Laid-Open No. 5-79398, a heating element is internally mounted and fixed in the horizontal portion of the L-shaped heater tube. The above immersion heater and a non-ferrous metal molten metal holding furnace equipped with this immersion heater have been proposed. However, in the case of this conventional technique, particularly focusing on the structure of the immersion heater, since the heating element is a rod-shaped fixed type, it cannot be replaced when damaged, and the L-shaped heater tube is made of ceramic. -Because it is a three-piece adhesive joint, it often breaks at this joint, has a short life, and has to be equipped with a supporting rod for supporting the free end, which complicates the structure. , And the heating element of the heater itself is rigid and inflexible,
Therefore, since it can be accommodated only in the L-shaped horizontal portion, there is a problem that the heat transfer range is narrow and the heat generation efficiency is poor.

The heater tube is a ceramic U-shape or L-shape, and the straight tube portion and the curved tube portion of the heater tube are integrally formed without being separated. Therefore, conventionally, since the straight pipe portion and the curved pipe portion are mainly adhered to each other by the adhesive material, it is possible to solve the problem that the portion is broken and reaches the end of its life, and a long-life product can be obtained. . In order to obtain such an action and effect, in the present invention, the size of the arc of the heater tube curved pipe portion is set to a curvature having an inner diameter of a radius of 100 mm or more. With such a curvature, the joint will not be damaged, and the interior of the heating element described later can be smoothly performed. Next, in the present invention, the heating element is made to have a flexible shape so that it can be smoothly installed inside the L-shaped or U-shaped heater tube of the present invention composed of the straight pipe portion and the curved pipe portion. There is. For this reason, the heating element can be installed in the U-shaped and L-shaped vertical portion-bent portion-horizontal portion as it is in an integrated form.
Moreover, since the length of the heating element can be increased, the heat transfer area can be increased, and so-called heat transfer efficiency can be increased. Further, the immersion heater of the present invention is such that the heating element housed inside the heater tube is not fixed and can be put in and taken out easily by being detachably housed, and therefore maintenance and replacement are possible. You can easily. Therefore, maintenance is reduced.
