Definitions
- the present invention relates to a cooling roll device used for a metal thin plate foil band manufacturing device, a continuous casting device, a resin plate, a resin film manufacturing device, and the like.
- metal cooling rolls have been used for various purposes such as continuous metal casting, hot rolling, and intermediate annealing.
- the amount of heat possessed by the molten metal is transferred to a metal roll, and the molten metal is continuously cooled by cooling the metal roll to produce a thin plate foil band.
- This roll gets hot and needs to be cooled.
- Rolls are also frequently used in the production of resin films and the like, and require cooling. These cooling rolls may be air-cooled if the temperature does not rise so much, but in most cases they are water-cooled. However, if the temperature of the roll is very high, even water cooling causes a difficult problem.
- the single roll liquid quenching method when manufacturing a thin sheet metal strip of amorphous metal, the single roll liquid quenching method is used. Conventionally, it has been considered to use an iron-based amorphous alloy with a small power loss for the iron core of a transformer or a motor, and the cooling roll used when manufacturing an amorphous metal thin plate foil band is a thin plate foil band. It is one of the hottest cooling rolls used in the equipment. In the single-roll liquid quenching method, high-temperature molten metal is ejected from a metal discharge nozzle provided on the upper part of the cooling roll onto a cooling roll that rotates at high speed, and the metal is cooled and solidified by the cooling roll to obtain a thin plate metal.
- the roll is cooled by supplying a large amount of water into the cooling roll, and a large amount of water is supplied into the cooling roll by a high-pressure pump. Need to be circulated.
- water is supplied into the cooling roll and the heated water is discharged.
- the cooling roll rotates, water touches the high temperature part on the inner surface of the cooling roll, the temperature of the water rises, and the heat corresponding to the temperature rise is deheated from the high temperature part as sensible heat and exhausted.
- the heat capacity to be exhausted is the average temperature of the discharged water minus the average temperature of the supplied water multiplied by the specific heat of the water and the amount of water.
- it is generally done by flowing a large amount of water.
- the contact time between the inner surface of the cooling roll and the water becomes shorter and the average temperature on the discharge side is less likely to rise. Even if the amount of water supplied is increased significantly, the specific heat does not change, so the cooling efficiency does not increase.
- the thickness of many industrially realized iron-based amorphous foil strips is about 0.025 mm. If this thickness is doubled to 0.05 mm, the productivity is doubled and the cost can be greatly reduced. If it becomes 0.1 mm, the productivity will increase four times. However, since the heat capacity of the molten alloy is also doubled or quadrupled, cooling cannot keep up, and the conventional methods have limited the thickness to about 0.05 mm and the width to about 50 mm. Amorphous metal is used for iron cores of motors and transformers, but the width is insufficient and amorphous foil strips of this thickness have not yet been commercialized.
- the biggest problem with this latent heat cooling method is that a large amount of steam is generated, which spouts out from inside the cooling roll body at high speed. This speed becomes the same as that of a typhoon due to expansion during evaporation.
- the treatment method is to release the steam into the atmosphere as it is, or to cool the steam and return it to hot water, and circulate this hot water in the furnace for reuse. It is a waste of water and energy to release all the steam to the atmosphere, and the method of cooling and recovering the steam has a problem that the cooling device requires a large installation space and cost.
- the cooling roll device has a hollow roll body for cooling a high-temperature object in contact with the outer peripheral portion, a water supply pipe that supplies water or hot water in a liquid state in the roll body, and a roll body.
- a first cooling roll having a discharge port for discharging the generated water vapor, receiving the water vapor from the discharge port, exchanging heat with a medium having a boiling point lower than that of water, and returning the water vapor to the inside of the roll body as a liquid.
- FIG. 1 It is a schematic block diagram which shows an example of the thin plate foil band manufacturing apparatus which uses the cooling roll apparatus by one Embodiment of this invention. It is an axial sectional view which shows the structure of the cooling roll part in the cooling roll apparatus by one Embodiment of this invention. It is a schematic diagram which shows the structure of the cooling roll apparatus by one Embodiment of this invention.
- FIG. 1 is a schematic configuration diagram showing an example of an amorphous metal thin plate foil band manufacturing apparatus by a single roll liquid quenching method in which a cooling roll apparatus according to the present invention is used.
- an alloy molten metal 4 heated by a high-frequency coil 3 in a crucible 2 and in a molten state is held above a cooling roll 1 made of copper or a copper alloy having good thermal conductivity.
- the alloy molten metal 4 receives pressure such as atmospheric pressure in the direction of the arrow 5 and is extruded to the upper surface of the cooling roll 1 through the metal discharge nozzle 6 to form a hot water pool, and the heat of the alloy molten metal 4 is metal.
- the molten alloy 4 is cooled and solidified by moving to the cooling roll 1 made of the above-made metal.
- the cooling roll 1 By rotating the cooling roll 1 around the roll shaft 7 in the direction of arrow 8 by a drive device (not shown), the molten alloy 4 is cooled to form a thin alloy foil band 9, and the peeling gas is directed in the direction of arrow 10.
- the alloy foil band 9 is peeled off from the outer surface of the cooling roll 1 by spraying on.
- FIG. 2 is an axial sectional view showing a schematic configuration of a cooling roll 1 used in a cooling roll device according to an embodiment of the present invention.
- a hollow roll shaft 7 is provided on one end side of a hollow cylindrical cooling roll 1, and a water supply pipe 11 penetrates the hollow portion of the roll shaft 7 and extends downward to the hollow portion of the cooling roll 1. It is provided to spout out.
- the alloy molten metal 4 comes into contact with the upper part of the outer surface of the roll body 13, and the temperature of the roll body 13 becomes high, causing the water in the roll body 13 to evaporate. When the water evaporates, it takes heat from the roll body 13 as latent heat and cools the cooling roll 1.
- the generated steam is discharged from the steam discharge port 15 in the direction of the arrow 18 through the hollow portion of the steam ejection cylinder 14. 16 represents the water level when rotated at high speed.
- FIG. 3 is a schematic diagram showing a schematic configuration of a cooling roll device 100 according to an embodiment of the present invention, and is configured by incidentally connecting a binary power generation device 200 to the cooling roll 1 in FIG.
- the water vapor generated in the body of the cooling roll 1 is guided to the inside of the preheater 19 by the pipe 25, and preheats the liquid medium in the medium pipe 29 arranged in the preheater 19. After that, it is guided by the pipe 26 into the evaporator 20 arranged next to the preheater 19 to evaporate the medium in the medium pipe 29.
- the pipe 25 is actually configured to connect the steam blowout cylinder 14 of the cooling roll 1 and the steam inlet (not shown) of the preheater 19, but in FIG. 3, in order to show the direction of the steam flow. It is schematically illustrated by an arrow.
- the pipe 26 is also configured to actually connect the steam outlet (not shown) of the preheater 19 and the steam inlet (not shown) of the evaporator 20, but in FIG. 3, in order to show the direction of the steam flow. It is schematically illustrated by an arrow.
- the medium When the medium evaporates, it takes the heat of steam as latent heat and returns the steam to hot water. At this time, the volume of water vapor shrinks to the volume when the water evaporates. Due to this contraction, the expansion pressure at the time of evaporation of water is absorbed and no particular problem occurs.
- the returned hot water passes through the pipe 27, is combined with the hot water partially returned to the hot water by the preheater, passes through the pipe 28, and is returned to the inside of the body of the cooling roll 1. In this way, the thermal cycle of the steam system is configured.
- the pipe 27 is actually configured to connect the hot water outlet (not shown) of the evaporator 20 and the hot water inlet (not shown) of the preheater 19, but in FIG. 3, in order to show the direction of the hot water flow. It is schematically illustrated by an arrow.
- the pipe 28 is also actually configured to connect the hot water outlet of the preheater 19 and the water supply pipe 11 of the cooling roll 1, but in FIG. 3, in order to show the direction of steam flow. It is schematically illustrated by an arrow.
- the medium preheated by the preheater 19 is completely evaporated by the evaporator 20, is guided to the medium turbine 21 by the medium pipe 29, rotates the medium turbine at high speed, and generates electricity by the generator 22.
- the medium that has rotated the medium turbine passes through the medium pipe 30, is cooled by the cooling water 31 in the condenser 23, returns to the liquid medium, and is sent to the preheater 19 by the medium pump 24. In this way, the thermal cycle of the medium system is configured.
- the medium pipe 29 is actually configured to connect the medium outlet (not shown) of the condenser 23 and the medium inlet (not shown) of the medium turbine 21, but in FIG. 3, the direction of the flow of the medium is shown. Therefore, it is schematically illustrated by an arrow.
- the medium pipe 30 is also configured to actually connect the medium outlet (not shown) of the medium turbine 21 and the medium inlet (not shown) of the condenser 23, but in FIG. 3, the direction of the flow of the medium is shown. Therefore, it is schematically illustrated by an arrow.
- the binary power generator 200 heats and evaporates a medium having a boiling point lower than that of water by steam as a heating source, and turns the medium turbine with the steam. It is called binary cycle power generation because it uses two thermal cycles, a steam system and a medium system, to generate electricity.
- a medium having a boiling point lower than that of water used here for example, an organic medium such as CFC substitute, a mixed solution of water and ammonia, or the like can be used.
- the generated electric power can be used for melting the metal supplied to the cooling roll 1 and can also be used for the electric power supplied to the binary power generation device 200. In either case, a significant portion of the enormous amount of energy used for melting can be recovered as electricity, resulting in significant energy savings compared to a simple water cooling system and compared to releasing water vapor into the atmosphere. The amount of water used will also be significantly reduced,
- the cooling roll 1 slowly starts to rotate in the direction of the arrow 8, and when the predetermined rotation speed is reached, the cooling roll 1 continues to rotate while maintaining this rotation speed.
- the molten alloy 4 is ejected from the metal discharge nozzle 6 above the cooling roll 1 onto the outer surface of the cooling roll 1 rotating at high speed, the ejected molten alloy 4 comes into contact with the outer surface of the cooling roll 1 and the molten alloy 4 is ejected.
- the heat is transferred to a cooling roll 1 made of copper or a copper alloy having good thermal conductivity, and this heat is rapidly transferred from the outer peripheral portion of the cooling roll 1 to the inner peripheral portion having a low temperature, and the rapidly cooled thin plate is made of an alloy foil. It becomes a band 9 and is discharged.
- the heat of the inner peripheral portion of the cooling roll 1 transfers heat to the water adhering to the inner wall surface, raises the temperature of the water when the temperature of the water is low, and raises the temperature of the water when the temperature of the water is high, for example, 99.9 ° C. At that time, the temperature exceeds 100 ° C immediately and the water evaporates instantly.
- water takes a large amount of heat from the metal on the inner surface of the cooling roll 1 as latent heat.
- the latent heat is 539 times the sensible heat per 1 ° C.
- this cooling phenomenon is instantaneously performed on the inner wall surface of the cooling roll, and is continuously performed in accordance with the rotation of the cooling roll 1.
- This evaporation phenomenon is proportional to the amount of heat supplied to the inner wall of the cooling roll 1. As the amount of heat supplied increases, the amount of evaporation increases proportionally, and when it is evaporating, the temperature at that point is maintained at approximately 100 ° C. When the production starts, the temperature of the water accumulated in the inner circumference of the roll reaches almost 100 ° C. When the temperature reaches 100 ° C., evaporation starts from the entire inner peripheral wall surface of the roll and the temperature of the entire cooling roll is lowered.
- the material of the alloy molten metal 4 is manufactured when the iron-based amorphous alloy, the plate thickness of the alloy foil band 9 is 0.1 mm, the plate width is 250 mm, the production speed is 25 m / sec, the cooling start temperature is 1300 ° C, and the cooling end temperature is 300 ° C.
- the weight of the amorphous alloy foil band is about 4.5 kg / sec.
- the amount of water required by the conventional technique by water circulation is 72 kg / sec when the inlet temperature of the cooling roll is 30 ° C and the outlet temperature is 40 ° C.
- the required amount of water is only 1.3 kg / sec.
- the amount of water is about 1.8% compared to the conventional technique.
- the amount of water used is significantly small, and even on the discharge side, the steam at 100 ° C is only returned to the hot water at 100 ° C, so the equipment is relatively simple. It's fine.
- the generated steam can be recovered as electricity by binary power generation, a considerable amount of the power required to melt the alloy can be recovered, which enables very energy-saving production and costs. Can lead to a significant reduction in electricity.
- the steam can be cooled and returned to hot water, and this hot water can also be recirculated for roll cooling, which also saves a large amount of water.
- the heat capacity of the medium used for binary power generation is smaller than that of water, the amount of cooling water for returning the evaporated medium to a liquid can be smaller than that for returning water vapor to a liquid. Since the structure of the cooling roll 1 is very simple as shown in FIG. 2, it can be manufactured at low cost. Since the pressure inside the pipe does not become so high, maintenance is easy.
- the inside of the cooling roll 1 is shown by a simple structure, but if it is desired to increase the evaporation area, a structure having irregularities inside the body portion 13 may be used. Further, although the water supply and the steam discharge port are provided on opposite sides, water may be supplied from the steam discharge port side.
- liquid quenching method an example of the liquid quenching method is shown, but the same principle can be used for a cooling roll or the like used in a continuous casting machine or the like.
- medium turbine 21 and the generator 22 are shown as separate devices, but an integrated turbine generator can also be used.
- the cooling roll device used in the amorphous metal thin plate foil band manufacturing device, the resin plate, the resin film manufacturing device, etc. according to the embodiment of the present invention effectively cools the molten material such as the molten alloy and the molten resin. Allows you to continue.
