本考案は炉内が隔壁によつて分割されている炉
内に用いられる非金属電気抵抗発熱体に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a nonmetallic electrical resistance heating element used in a furnace where the inside of the furnace is divided by partition walls.
一般に炭化珪素質等の非金属電気抵抗発熱体は
棒状のもので、両端部は低抵抗としてターミナル
部及び炉壁内において発熱しないように構成され
ており、炉内部は冷端部より一桁程度高抵抗とし
て発熱するように構成されている。 In general, non-metallic electric resistance heating elements such as silicon carbide are rod-shaped, and both ends are constructed with low resistance so as not to generate heat in the terminal part and the furnace wall, and the inside of the furnace is about an order of magnitude lower than the cold end. It is configured to generate heat due to its high resistance.

加熱されるから、異常発熱を起し隔壁を溶損した
り、発熱体が溶断したりするという事故が起る。 However, in the case where firing is performed simultaneously under different conditions such as temperature or atmosphere inside the furnace, it is necessary to provide a partition wall inside the furnace. In order to use a non-metallic heating element under such special conditions, with conventional heating elements, the heating element is heated within the partition wall with the same electric power as the heating part, so there is a risk of abnormal heat generation and melting of the partition wall. , an accident may occur where the heating element melts down.

部を介して一体に結合されてなるものである。 The present invention has developed a heating element suitable for such a special furnace body, which has low-resistance cold ends at both ends, and has one or more high-resistance heating parts in the furnace and a low-resistance part in the partition wall. They are integrally connected via.

一体に結合されてなるものである。 In other words, the part that crosses the heating chamber partitioned by the partition wall serves as a heat generating part with a predetermined high resistance and heats the heating chamber, the part inside the partition wall has a low resistance so that it does not generate heat, and furthermore, in other adjacent heating rooms. is a heat generating part with a predetermined high resistance necessary to change the atmosphere or temperature or to maintain the same conditions, and a low resistance cold end part is used to prevent abnormal heat generation inside the furnace walls at both ends and to attach electrodes outside the furnace. It is integrally connected to the heat generating part.

FIG. 1 shows an embodiment of the present invention, in which 1 is an outer wall of a furnace body, and 2 is a partition wall that partitions the inside of the furnace into two parts. Reference numeral 3 denotes a heating element of the present invention, and both ends thereof are low resistance parts for attaching terminals, and high resistance heating parts 5, 5' are provided across heating chambers 4, 4'. In this case, the portion 6 of the heating element penetrating through the partition wall 2 needs to have a low resistance so as not to reach a high temperature within the partition wall.

can be used independently of each other; for example, by changing the atmosphere, changing the fired product, or changing the heat generating area or resistance value of the heat generating part, the temperature inside the heating chamber can be changed and the temperature inside the two furnaces can be changed. can be used at the same time.
炉内を異つた条件で同時に使用するには従来の

ることができるという効果を有する。 In order to use the inside of the furnace under different conditions at the same time, with conventional heating elements it was necessary to prepare and process two or more furnace bodies, but by using the heating element of the present invention, it can be done with high thermal efficiency. This has the advantage that a heating element and electric power can be used.

は容易ではない。 In addition, the material of the heating element is a non-metallic heating element such as silicon carbide, zirconia, or molybdenum silicide.
Alternatively, this can be easily achieved by introducing a resistance value changing material, but in the case of a metal heating element, it is not easy to change the resistance value in the middle of an integrated heating element.
