摘要： PURPOSE:To take out fibers continuously without stopping a centrifugal spinning device, by setting a fiber guide duct at the side or the bottom of a centrifugal spinning part and laying a suction device opposingly to a guide opening through a meshy belt conveyor. CONSTITUTION:Fibers 11 which are jetted from a revolving spinning nozzle 5 and solidified are sucked from a suction duct 22 of a suction device 23 through a guide duct 21. Between both the ducts 21 and 22 is set a meshy belt conveyor 24 and the fibers 11 are accumulated on the belt conveyor 24. A lamellar fiber group 1 having desired thickness can be continuously obtained by changing the velocity of the belt conveyor.

摘要： PURPOSE:To improve breakage yield of carbon fiber, by placing a cylinder having opening at the top and bottom and surrounding a rotary nozzle for centrifugal spinning, lowing gas stream from the upper part of the cylinder and placing an air-permeable mesh belt conveyor under the cylinder. CONSTITUTION:A centrifugal nozzle 2 is surrounded with a cylinder 5 and a belt conveyor composed of a mesh belt 7 is placed under the cylinder. Gas is passed from the top to the bottom of the cylinder 5. Scattered fibers are carried by the descending gas stream 6, entangled, soft-landed on the belt 7 and deposited (11). Even extremely short fibers and fine pitch particles are passed through the belt 7 together with the gas stream and deposited on the belt under the cylinder.

摘要： PURPOSE:To make it possible to continuously take out fibers to be continuously produced to the outside and transfer the fibers at the same time, by providing a pair of rolls, oppositely installed at the bottom opening end of the outside wall of a centrifugal spinning part to afford horizontal shaft lines of both and consisting of an elastic member. CONSTITUTION:A pair of rotating press rolls 20 and 20, consisting of an elastic member and oppositely provided at the bottom end of a small-diameter part of an outside wall 7 are installed to afford horizontal shaft lines and press to each other. A carbon raw material 2 radially jetted from nozzle holes of a spinning nozzle 5 is formed into short fibers, which are passed through the inner surface of the outside wall 7 to form a cylindrical fiber group 11' and flow to the outside. The outflowing cylindrical fiber group is nipped between the pair of rotating press rolls 20 and 20 and elastically pressed to give a beltlike fiber group 1 which is then taken off.

摘要： PURPOSE:To feed a thin metallic sheet to an in-line mill at a temp. adequate for rolling regardless of the thickness thereof by forming an oxidation preventive atmosphere zone from right under casting rollers up to just before the in-line mill, decreasing the air-fuel ratio of the fuel to be burned and separately providing cooling and heating means. CONSTITUTION:An oxidation preventive atmosphere furnace 1 and an oxidation preventive holding furnace 8 are provided from right under the casting rollers 54 up to just before the in-line mill. The combustion gas formed by burning the fuel and air having about 1-0.6 air-fuel by burners 3 is fed into the furnace 1. The unburned combustion gas is thereby generated in the furnace 1 and is bound with oxygen to generate the oxidation-free atmosphere. The generation of scale on the thin metallic sheet 55 passing in the furnace 1 is obviated and the temp. in the furnace is controlled to about 1,000-1,150 deg.C. Cooling water is passed to a pipe 12 from a cooler 13 to control the temp. to the adequate temp. if the sheet 55 is thin and the temp. thereof rises too fast. The sheet 55 is heated by electric heaters 11 to control the temp. thereof to the adequate temp. if the sheet is thick.

摘要： PURPOSE:To feed a thin sheet at a temp. adequate for rolling to an in-line mill regardless of the thickness thereof by forming an oxidation preventive atmosphere zone from right under casting rolls up to just before the in-line mill and decreasing the air-fuel ratio of a burner combustion gas to that the temp. control is made possible. CONSTITUTION:An oxidation preventive atmosphere furnace 1 and an oxidation preventive holding furnace 8 are provided as a temp. control zone from right under the casting rollers 54 for the thin metallic sheet 55 up to just before the in-line mill 56. The combustion gas formed by burning the fuel and air adjusted to about 1-0.6 air-fuel ratio by the burners 3 is supplied into the furnace 1 to decrease the air-fuel ratio in the furnace 1. The unburned combustion gas of a high temp. is thereby generated and is bound with the oxygen in the furnace 1 to generate the oxygen-free atmosphere therein. The generation of scale on the thin metallic sheet 55 passing in the furnace is obviated and the furnace temp. is controlled to about 900-1,200 deg.C. The unburned combustion gas is discharged from a discharge pipe 7. The sheet 55 is then fed via the furnace 8 to the mill 56. The sheet 55 is thus fed to the mill 56 at the temp. adequate for rolling regardless of the sheet thickness.

摘要： PURPOSE:To prevent the generation of a cold shut on the surface of an ingot by providing a control system having a high response speed so that level fluctuations can be decreased particularly with a high frequency component. CONSTITUTION:A molten steel level 18 is detected by a level sensor 12. The level signal enters a signal processing system 13 from which the frequency component, for example, the level fluctuation component below 2 seconds fluctuation period is fed to the control system 9 and the low frequency component, for example, the level fluctuation component above 2 seconds fluctuation period is fed to a stopper position control system 11. The level fluctuation period of about

摘要： PURPOSE:To make the prevention of the transverse crack and bulging of an ingot possible by detecting the change of the load acting on drums and feeding the detection signal back to the flow rate of a tundish or the rotating speed of the drums thereby stabilizing the surface of the molten metal between the drums. CONSTITUTION:The load is detected by a load cell 15 and is fed back to the input of a tundish flow rate controller 8 which controls the molten steel level between the drum. The opening degree of a stopper valve 10 in the tundish 1 is changed to change the molten steel level between the drums 1, by which the thickness of the shell is made constant. The transverse cracking and bulging of the ingot are thus prevented while the molten metal surface between the drums is stabilized.

摘要： PURPOSE:To prevent the disturbance of meniscus and to obtain an ingot having a good surface characteristic by disposing a baffle plate and receiving plate in a pouring nozzle, forming a discharge port into a slit shape and immersing the top end thereof into a molten steel. CONSTITUTION:The molten steel flowing out of a restrictor 5 collides against the baffle plate 6 and the molten steel is dispersed by the receiving plate 7 uniformly in the transverse direction of drums 3, 3' and is accumulated in the nozzle. The molten steel overflows from the receiving plate into the discharge port 8. The pouring nozzle is immersed below the meniscus and a pool 10 is formed at the port 8. The sectional area of the port 8 is made extremely larger than the sectional area of the restrictor 5 and therefore the molten steel flow gently out of the port 8.

摘要： PURPOSE:To cast continuously and safely a thick slab at a high speed by using endless belts which are made of an elastic material and move in contact with said belts at the same speed to constitute the closed members on both sides of the endless traveling device in a belt type continuous casting device for the metallic belt. CONSTITUTION:A molten steel is poured into the space 1 constituted of a pair of the endless belts 2, 2 for casting and the side blocks disposed to the parts of both side faces thereof in the belt type continuous casting device. The molten steel is water- cooled to solidify by cooling water nozzles 7 by which the steel slab is produced. The side blocks in such a case are constituted of a pair of the endless belts 12 which are made of the same material as the material of the belts 2, have many rigs 13 on the rear side and are provided with elastic and flexible members 14 made of synthetic rubber, etc. in the part in contact with the belts 2. Cooling water passages are formed between said blocks and the ribs 13. Since the casting space is constituted of two pairs of the endless belts 2, 2 and 12, 12 moving at the same speed, the continuous casting at a high speed is made possible without inducing the injury of both belts as a result of sliding between the belts and without defects such as leakage of the molten steel and breakout of the slab.
