本発明は加熱炉の吸引成型方法、特に加熱炉の断熱材と
発熱体を一体に吸引成型する方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for suction molding a heating furnace, and particularly to a method for integrally suction molding a heat insulating material and a heating element for a heating furnace.
第２図は従来の加熱炉の一部を示し、１は炉心を囲むよ

ー状断熱材１の内面に一体に取り付けた発熱体を示す。Figure 2 shows a part of a conventional heating furnace, in which 1 is a cylindrical fibrous heat insulating material made of fine ceramics such as silica or alumina that surrounds the core, and 2 is the inner surface of this fibrous heat insulating material 1. Shows the heating element integrally attached to.

品を型３から抜き取るといった作業を行っている。Generally, in order to improve the durability of such a heating furnace, it is necessary to reduce the difference in temperature between the temperature inside the furnace and the heating element 2 as much as possible, and to keep the temperature of the heating element 2 as low as possible. For this purpose, it is ideal that the heating element 2 is exposed inside the heating furnace without being buried in the heat insulating material 1 and covered with it. When performing suction molding using a heat insulating material as a raw material and integrally with a heating element, in order to enable the molded product to be released from the mold after molding, it is necessary to first set the thickness of the mold 3 that has air permeability for suction molding. A layer 4 of fibrous heat insulating material with a thickness of about 2 m/m is formed on the mold 3 by wrapping it or by suction molding, and
A heating element 2 is attached on top of the heating element 2, and then this is immersed in a muddy fibrous heat insulating material, and the above-mentioned mold 3
After the heat insulating material 1 reaches the required thickness by suction molding to suck moisture from the center of the mold, the molded product is removed from the mold 3 as shown in FIG.

事が出来なかった。Therefore, in the conventional heating furnace, the heating element 2 after molding has a layer 4 for releasing the mold with a thickness of about 2-/l on the inside, which increases the temperature of the heating element 2 when the temperature is raised. When used at high temperatures, it was necessary to remove layer 4 as shown in Figure 4. In addition, when suction molding is performed by directly attaching the heating element 2 to the mold 3 for suction molding, the friction between the heating element 2 and the mold 3 makes it very difficult to separate from the mold after suction molding, and when removing the mold. This method could not be adopted because the heating element 2 would be destroyed in many cases.
本発明はこのような欠点を除くようにしたものである。The present invention is designed to eliminate these drawbacks.

とする。In the suction molding method of the heating furnace of the present invention, the heating element is divided into a plurality of elements in the circumferential direction, and a heating element is placed directly on a mold in which each divided element is bent inward, and the heating element is placed outside the heating element. The present invention is characterized in that suction molding is performed so that the fibrous heat insulating material is formed to a desired thickness, and after molding, the dividing elements of the mold are bent inward to take out the molded product from the mold.

取り出されるようになる。In the heating furnace suction molding method of the present invention, the heat insulating material is suction molded with the heating element placed directly on the mold without forming a layer for mold release between the mold and the heating element, and then the mold is removed. The molded article can be removed from the mold by folding the dividing elements inward.
以下図面によって本発明の詳細な説明する。 The present invention will be explained in detail below with reference to the drawings.

て行うようにする。In the present invention, as shown in FIG. 1, a cylindrical mold 3 is divided, for example, into four parts in the circumferential direction, and a notch slope 5 of approximately 45° is formed on the inner surface of the joint end of each divided element. Each divided element is allowed to bend inward until the notch slopes 5 come into contact with each other, and the heating element 2 is placed directly on the mold 3 thus formed without forming a layer 4 for releasing the mold. Then, suction molding is performed so that the fibrous heat insulating material 1 has a desired thickness on this heating element 2, and when the molded product is removed from the mold 3 after molding, the slope portions 5 of the divided mold elements match. Fold it inward as shown by the two-dot chain line in Figure 1 until it looks like this.
