摘要： PURPOSE:To remarkably shorten the time required for heating and cooling in producing carbon fiber, heat-treat the fiber with high productivity and obtain the carbon fiber by temporarily compressing an assembly of raw material fiber, reducing the volume, restoring the reduced volume and heat-treating the fiber. CONSTITUTION:An assembly (M) of raw material fiber which is a material to be treated is contained in a box 15 that is an open hollow container formed from a heat-resistant material such as graphite and the box and all is charged into a heating chamber 3 of a furnace body 1. The fiber assembly (M) contained in the box 15 is then compressed with a compressing device 20 equipped with a liftable and lowerable pressing plate 23, etc., having a size capable of advancing into the box 15 in rods 22 of cylinders 21 installed downward in the top of the furnace body 1 to temporarily reduce the volume of the fiber assembly. The reduced volume is then restored to heat-treat the fiber assembly. Thereby, air contained in the interior of the fiber assembly (M) is pushed out and the surrounding air at a high temperature subsequently enters the interior of the fiber assembly (M) to remarkably reduce the treating time. As a result, the fiber assembly is heat-treated with excellent productivity to afford the objective carbon fiber.

摘要： PURPOSE:To obtain an apparatus effective in the continuous production of carbon powder by combining a heating furnace, a rotary tube, a charging apparatus, a cooling means, a gas-supplying means and a gas discharging means in such a manner as to perform a specific action. CONSTITUTION:A rotary tube 5 is inclined to lower its tip end and is heated with a heater 12. At the same time, an atmospheric gas is supplied to the rotary tube from a gas-feeding pipe 17 and sucked through a gas-discharging pipe 18. A raw material 6 is charged to the rotary tube 5 with a charging apparatus 7 while rotating the rotary tube 5. The charged raw material 6 is lifted with a lifter and dropped according to the rotation and slowly transferred forward in the rotary tube 5. In the course of passing the raw material 6 through the base end part of the rotary tube 5 having relatively low temperature, the volatile components are evaporated from the raw material 6 and the evaporated gas is sucked through the gas-discharging pipe 18 and quickly discharged from the rotary tube. The raw material 6 is further transferred and calcined to form carbon powder 30 in the course of passing through the intermediate part having the highest temperature.

摘要： PURPOSE:To prevent work from contamination and oxidation induced by ambient air by providing a work housing chamber on a traveling carriage running between a degreasing furnace and a sintering furnace, mounting the base of a flexible tube which forms an airtight chamber between the work housing chamber, the degreasing furnace and the sintering furnace, and evacuating the internal parts of the work hocusing chamber and the airtight chamber. CONSTITUTION:Work is housed in a housing chamber 21 from a work station 1. A transfer device 4 is self-propelled to the front of a degreasing furnace 2 so that it may be connected with the degreasing furnace 2 by extending a flexible tube 16. After the housing chamber 21 is evacuated inside, work is fed into the degreasing furnace 2. When degreasing process is over, the work is transferred from the degreasing furnace 2 to the housing chamber 21. The transfer device 4 is positioned in front of a sintering furnace 3 so that work may be transferred to the sintering furnace 3 and picked up in a similar manner to the furnace 2. The transfer device 4 is self-propelled so that the work may be picked up to a work station 1. This construction makes it possible to keep the work clean not affected by impurities remaining inside the furnace, and prevent the work from being exposed to the ambient air.

摘要： PURPOSE:To eliminate the elongation and/or meandering movement of a conveyer during operation by a method wherein the upper half of the conveyer is moved by an upper walking beam into the direction of transfer of works to be heated while the lower half of the same is moved by a lower walking beam into reverse direction. CONSTITUTION:An upper walking beam 22 and a lower walking beam 23 are lifted by a first driving means 26 from an upper fixed beam 17 and a lower fixed beam 18 while the upper walking beam 22 is moved by a second driving means 28 to the transfer direction of works to be heated and the lower walking beam 23 is moved by a third driving means 30 to the reverse direction whereby a conveyer 21, installed on the upper walking beam 22 and the lower walking beam 23, is moved into one direction by a predetermined distance through rotation. The conveyer 21 is sent by one pitch surely in a condition that the same is lifted by the upper walking beam 22 and the lower walking beam 23 and, therefore, the meandering movement and elongation of the conveyer 21 will never be generated.

CONSTITUTION:On the upper face of a heat flow measuring plate 15 and a compensating cooling plate 16, the lower temperature measuring plate 23 is placed, and on its upper face, a standard heat conducting plate 24 having a heat insulating property is placed, and on its upper face, a sample S is placed, and on its upper face, the upper temperature measuring plate 25 is placed. In this state, the temperature of the lower face of the standard heat transmission plate 24 is held at t0, and also, the temperature of the upper face of the sample S is held at a measured temperature T, and a standard superconducting rate of the sample S is derived. Based on its overall superconducting rate, the characteristic of a superconducting rate of the standard heat conducting plate 24, thickness of the sample S and thickness of the standard heat conductive plate 24, the superconducting rate of the sample S is derived.

摘要： PURPOSE:To increase the cooling velocity and to improve the cooling efficiency by providing a circulating fan confronted with a heat-treating chamber, further providing an exclusive circulating fan to a cooling gas passage, and passing a sufficient amt. of an atmospheric gas through the cooling coil part. CONSTITUTION:A material A to be treated is placed on a hearth 32 of a heat- treating chamber 25, and the inside of the furnace is kept under vacuum. An atmospheric gas is circulated by operating a circulating fan 34 at the upper part of the furnace body, the gas is heated by passing an electric current through a heating element, and the material A to be treated is heated. When the gas flows into the heat-treating chamber 25 from a heating gas passage 26, the gas is guided by a guide plate 46, and distributed uniformly. Accordingly, sufficient heat-treating performance can be obtained. Although the circulating fan 34 is successively driven in a cooling cycle, a damper 38 is opened, and a circulating fan 44 used exclusively for cooling begins to operate. Consequently, a part of the circulating gas is circulated through the circulating passage in the cooling system, and the material A to be treated is cooled. By said mechanism, the heat- treating performance can be improved with a simple structure.

摘要： PURPOSE:To maintain the life of a seal ring for a long period by providing a door device which moves the seal ring provided on the door body side to the position to make the ring free from radiation heat and obviates slip of the seal ring when the door is held open. CONSTITUTION:When an open/shut shaft 20 is rotated counterclockwise, a connecting shaft 23 is moved by turning of an open/shut arm 22 so as to draw an arc, thereby moving a door body 8 and a shielding door 10 so as to detach respectively from a partition wall 5 and a heating chamber 3. An oscillating rail 26 is oscillated counterclockwise via a guide roller 25 by the moving door body 8. When the roller 25 arrives at the curved part of a guide groove 27, the door body 8 rotates clockwise. The movement of the body 8 (seal ring 32) until said body detaches from the wall 5 is thus made into parallel movement, by which the slip between the ring 32 and the wall 5 is eliminated. The shaft 32 detaches further from the aperture and the rail 26 inverts to a clockwise direction on descending of the roller 25 and arriving at the horizontal part of the groove 27 so that the door body 8 surface attached with the seal ring is thoroughly directed downward.
