Claims

[Claims for Utility Model Registration] 1. A furnace body having a sample charging inlet and an outlet;
The furnace body is equipped with a heater provided inside the furnace body and a transfer mechanism for transferring the sample, and the sample charged into the furnace body from the charging port is transferred by the transfer mechanism and carried out from the carry-out port. , in a continuous heat treatment furnace in which the sample is heated intermittently or continuously by heating the sample with a heater, the transfer mechanisms are arranged at predetermined intervals along the transfer direction of the sample, and each It consists of a plurality of rollers that extend in the horizontal direction orthogonal to the sample transport direction and support the sample from below, a roller support that rotatably supports the rollers, and a drive mechanism that rotates the rollers. A continuous heat treatment furnace that is characterized by 2. The continuous heat treatment furnace according to claim 1, wherein the roller is made of a heat-resistant material such as graphite, heat-resistant ceramics, or heat-resistant metal. 3. The roller has a rotating shaft and two rollers that are spaced apart from each other and are respectively attached to predetermined positions on the rotating shaft.
Utility model registration claim 1 or 2, characterized in that the rotating shaft is supported by the roller support near the mounting position of the wheel. continuous heat treatment furnace.
