PROBLEM TO BE SOLVED: To solve problems that, in conventional batch-type heat treatment furnaces, bearings supporting a retort rotatably are easily damaged due to a heat impact and are difficult to absorb the expansion of the retort, and in a structure where the retort is supported rotatably by a slender roller below a furnace body, rollers may be damaged due to heat, and furthermore, in the structure where one end of the retort is directly connected with a rotary motor, the motor may fail due to the heat impact, and the manufacturing cost of the retort is also high.SOLUTION: A rotary retort-type heat treatment furnace forms a simple structure in which a roller is used for bearing both ends of a retort, and the simplified rotary mechanism of the retort is rotated with a rotary motor that is fixedly arranged on the side of a furnace body. In addition, the retort becomes a simple structure that is symmetric in right and left, and the inside diameter of both ends of the retort is 0.2-0.5 times that of a central part thereof, and an angle of a tapered part to the rotary shaft of the retort is 20-40 degrees. |
