摘要： PURPOSE:To obtain the title electrode of enhanced flexural strength, by kneading granular coke, binder pitch, and a specific carbon fiber-carbon composite, forming and calcination followed by graphitization. CONSTITUTION:First, 20-75vol.% of carbon fiber bundles each composed of 100-10,000 filaments are formed into rods using a carbonaceous binder (e.g. coal-based pitch). These rods are treated at low temperatures in an oxidative atmosphere followed by calcination at 600-1,000 deg.C in a non-oxidative atmosphere to produce a calcined product. Secondly, this product is put to oxidation treatment at 500-600 deg.C for 1-10min, in an inert gas atmosphere containing 5-50vol.% of an oxidative gas followed by cutting into a rodlike carbon fiber- carbon composite of 10-60mm length. Thence, (A) 100wt.% of size-regulated granular coke, (B) 25-50wt.% of softening point-regulated binder pitch, and (C) 1-10wt.% of said composite are blended and kneaded followed by forming, and calcination at 800-1,200 deg.C, then graphitization at 2,300-3,000 deg.C.

摘要： PURPOSE:To produce a carbon fiber having uniform quality in high productivity, by using a tunnel furnace having an inlet part bent (obliquely) downward at least at the inlet end, suspending a fiber tow in the form of a reed screen on plural bars moving through the tunnel furnace and carbonizing the tow in the state. CONSTITUTION:Fiber tow 1 subjected to flame-resistant treatment or infusibilizing treatment is successively suspended on a bar 2 at the inlet part 7 placed (obliquely) under the inlet end of a carbonization furnace and is successively transferred through the furnace in suspended state. The heating gas is made to uniformly contact with each fiber tow in the furnace and the generated gas is uniformly dissipated to suppress the generation of uneven carbonization of the tow.

摘要： PURPOSE:To keep the oxygen concentration in a carbonization zone of a furnace at a low level, by using a tunnel furnace having a feeding part bent (obliquely) downward at least at the inlet end of the furnace and introducing an inert gas into the furnace at least two parts comprising the part near the inlet end and the part near the outlet end of the furnace. CONSTITUTION:A tunnel furnace is maintained to a specific temperature and a specific atmospheric gas concentration by a heat source and a hot inert gas supplied through inlet ports 10, 10'... and discharged through openings 4, 16. A fiber tow 1 is supplied to a fiber tow supporting part A, folded by the aid of a bar 2 transferred by a conveyor 19, suspended on the bar 2 in the form of a reed screen, passed through a conveyor 6, transferred to a guide rail 12 and pulled up with a fiber tow releasing part B. The oxygen concentration in the carbonization zone of the furnace can be suppressed to

摘要： PURPOSE:To obtain meso-carbon microbead having uniform particle size, easily and economically on an industrial scale, by finely dispersing a bulk mesophase in a silicone oil bath and cooling the dispersion to effect the solidification of the mesophase. CONSTITUTION:A bulk mesophase formed by the growth and integration of optical anisotropic small particles formed in pitch by heat-treatment of pitch is finely dispersed in a silicone oil bath heated at a temperature higher than the temperature giving bulk mesophase viscosity of 200 poise by 60-160 deg.C. The finely dispersed mesophase is solidified by cooling to obtain the objective meso-carbon microbead.

摘要： PURPOSE:To prepare needle coke which shows a low degree of expansion in graphitization, by adjusting the quinoline insolubles content of raw material oil to a specified level and coking it by a delayed coking process. CONSTITUTION:A raw material oil consisting of hydrocarbon, such as coal tar, is introduced through a feeding pipe 1' and is mixed with solvent in a mixer 1. After separtion by sedimentaion in a static separating tank 2, the supernatant liquid is taken out from the top of the tank and condensed quinoline insolubles are discharged from the bottom. The modified oil with the adjusted quinoline insolubles content is charged into the bottom of a distillation tower 4 and is mixed with heavy distillate recovered in the distillation tower 4 from the fraction distilled in coke drums 6 or 7 so that the mixt. may have a Conradson carbon value of 19% or lower. The mixt. is then heated in a heating oven 5 and charged into the coke drum 6 or 7, where part of the raw material oil is subjected to coking under heat. The remaining portion is converted to steam and gas and led into the bottom of the distillation tower 4. The light fraction is taken out of the system and the heavy fraction is mixed with a new batch of raw material oil for charging into the drums 6, 7 via the heater 5.

摘要： PURPOSE:To automate the takeout of solid material, by detecting the vibration sound due to high pressure water jet in taking out the solid material with high pressure water after shaping, and controlling the position of jet. CONSTITUTION:Through-hole is provided at the center of the solid material 16 in the vessel 1 and high pressure water is jetted from the shaper 2 via the supporting rot 3 by the pump 6. On the other hand, while rotating the shaper 2 with the motor 4, the shaper 2 is lifted up or down via the wire 8 by the driving motor 11. The vibration sound detector 17 is fixed to an arbitrary position of the external wall of the vessel 1 to catch the oscillation sound. When the sound level from the detector 17 is lower than the lower limit L, the instruction X1 for stopping the transfer is output from the lower limit level setter 18. If higher than the upper limit H, the moving direction inversion instruction X2 is output from the upper level setter 19. If within the set value, the movement continuation instruction X3 is output. The judgement of lifting up or down with this instruction X3 is made by the moving direction memory circuit 23. Further, the program setter 22 has the function which changes the set value every movement and outputs it.
