摘要： PURPOSE:To continuously graphitize carbon powder by charging carbon powder into a mold from its top and heating the powder through the mold to graphitize the powder in the course of descending in the mold. CONSTITUTION:Carbon powder C used as a raw material is filled in a passing channel 19, a cooling chamber 11 and a discharge hopper 12. A mold 15 is heated with a heater 5, the carbon powder C supplied through a feed pipe 8 to a charging hopper 7 is continuously transferred to the mold 15 and a prescribed amount of carbon powder C is charged into a charging chamber 6 from the charging hopper 7 by intermittently pressing down a valve 9. At the same time, powder filled in the discharge hopper 12 is removed by a screw feeder 14. The carbon powder C is transferred from the charging chamber 6 into the passing channel 10 according to the above process and is slowly moved down by its own weight. The descending carbon powder C is preheated with the mold 15 during the passage through the preheating chamber 2 and heated to a temperature sufficiently high to effect the graphitization in the course of passing through the heating chamber 3. Graphite powder B is produced by the graphitization action.

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 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.

摘要： PURPOSE:To intermittently charge material substantially continuously in a heating tube by providing means for press-fitting a material to be heat treated, contained and conveyed in a containing chamber of an outer periphery to a heating furnace when it is opposed to a connector to a heater in cooperation with the rotation of a rotor. CONSTITUTION:Material fiber 2 is intermittently press-fitted in a constant quantity in a heating tube 4 while gas sealing by a charger 3 from a charging hopper 1. The material 2 is pressed down by a cylinder 15 provided at the upper part of the hopper 1, and contained in containing chambers A-D of a rotor 19 while cutting the material 2 by a cylinder 16 at the lower end of the hopper 1. When the chambers are opposed to a connector 23 to the tube 4, the material 2 is press-fitted in the tube 4 by a pusher 21. Thus, since it is constructed to press-fit the material 2 to be heat treated in the furnace 4 by press-fitting means in cooperation with the rotation of the rotor 19, the material can be intermittently charged in the furnace substantially continuously.

摘要： PURPOSE:To eliminate meandering movement during operation even in a large-size high-temperature furnace and make the title device endurable for the use of a long period of time by a method wherein a plurality of pawls, engaging intermittently and simultaneously with the projections of respective rod type members positioned in the part of straight line of a conveyer, is provided while the pawls are moved by a predetermined distance intermittently and simultaneously. CONSTITUTION:A walking beam 33 is constituted of a rail plate 30, moved by a driving source reciprocally into O-Q direction, and a running plate 32, moved reciprocally on the rail plate 30 by wheels 31 into P-R direction while a plurality of pawls 34, 34,..., engaging with respective projections 20 of rod type members 17 positioned in the part of straight line of a conveyer 19, is fixed to the upper part of the running plate 32 and the motion of O P Q R of the walking beam 33 is repeated as a whole whereby the conveyer 19 is moved by a given distance intermittently from the inlet port side of a furnace to the outlet port side of the same. A force is applied uniformly on respective rod type members 17 constituting the conveyer while the force is not applied at all on connecting members connecting the rod type members 17 with each other whereby the conveyer 19 will never be elongated or will never perform meandering movement.

摘要： PURPOSE:To exactly measure a heat transmission quantity by using a standard heat conducting plate which is formed by winding densely a sheet-like heat insulating material in a spiral shape and whose superconducting rate in the diameter direction is smaller than a superconducting rate in the thickness direction. CONSTITUTION:From the temperature difference of temperature measurement gas and its flow rate, a heat receiving quantity, namely, a heat transmission quantity Q transmitted through a sample S is derived, and from its heat transmission quantity, temperature theta1, theta2 of both the upper and the lower faces of the sample S and a thickness dimension (t) of the sample S, a superconducting rate lambda at the temperature of the sample S is derived by using an equation of lambda=Q, t/A(theta1-theta2). Also, the temperature of both the upper and the lower faces of a standard heat conducting plate 24 is also measured, and from those values and the heat transmission quantity Q, the superconducting rate of this standard heat transmission plate 24 is derived, and by comparing its value with a known superconducting rate, the result of measurement is verified, and also, it is corrected in accordance with necessity.
