Description

Technical Field

[0001] This invention relates to an amorphous crystallizer, and more particularly to a high-flow-rate cooled amorphous crystallizer. Background Technology

[0002] Amorphous crystallizers are used to produce amorphous ribbon. During production, molten steel ejected from the nozzle is sprayed in a planar flow onto the high-speed rotating copper sleeve of the crystallizer. Utilizing the high thermal conductivity of the copper sleeve, the molten steel, initially at 1400°C, is instantly cooled to below 200°C, forming the amorphous ribbon. Cooling water is continuously supplied to the inside of the copper sleeve via a cooling water channel, thus the flow rate of the cooling water channel is a crucial factor affecting the cooling rate at the copper sleeve. Currently, commonly used amorphous crystallizers, due to structural size limitations, employ a cooling water channel structure where water enters from one end of the spindle and exits from the other. The water inlet and outlet channels between the spindle and the copper sleeve are designed to intersect, resulting in limited space for the inlet and outlet channels and thus restricting the water flow rate, creating a bottleneck in the cooling capacity of the copper sleeve. Therefore, further improvements to the cooling water channel of the amorphous crystallizer are needed to achieve a larger flow rate of cooling water and further enhance the cooling capacity at the copper sleeve. Summary of the Invention

[0008] As a preferred technical solution, a seat end water outlet pressure cap is fixedly and sealed between the flow divider ring and the main shaft, located on the side of the water inlet guide fluid near the water inlet end. The seat end water outlet pressure cap and the water inlet guide fluid form a seat end water outlet guide channel. The flow divider ring is provided with a plurality of seat end water outlet flow holes that connect the cooling chamber and the seat end water outlet guide channel. The seat end water outlet flow holes and the seat end water outlet guide channel constitute the seat end water outlet channel.

[0009] As a preferred technical solution, the seat end water outlet cover includes a seat end water outlet cover body fixedly disposed between the diverter ring and the main shaft. The seat end water outlet cover body is integrally provided with a seat end water outlet inner support ring that can be pressed against the water inlet guide at the edge near the main shaft. The seat end water outlet cover body is integrally provided with a plurality of seat end water outlet outer supports that can be pressed against the water inlet guide on the inner side wall near the diverter ring.

[0013] Due to the adoption of the above technical solution, the cooling water supplied at the inlet end of this invention enters the cooling chamber through the inlet channel for cooling. After cooling, the water exits through two channels: the seat end outlet channel and the shaft end outlet channel. Therefore, in addition to water exiting from the spindle outlet end, this invention also increases the water outlet path by utilizing the seat end outlet box set on the machine base. Furthermore, the water distribution structure with water entering from the middle and exiting from both sides at the water distribution carrier eliminates the problem of water distribution channel intersection.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, exemplary embodiments of the invention are described only by way of illustration. It will be readily apparent to those skilled in the art that various modifications can be made to the described embodiments without departing from the spirit and scope of the invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0027] like Figures 1 to 10As shown, the high-flow-rate cooling amorphous crystallizer includes a base 1, on which a hollow spindle 2 is rotatably mounted. The spindle 2 is rotatably mounted via at least two sets of bearing mechanisms 21. A copper sleeve 3 is mounted in the middle of the spindle 2. After molten steel is sprayed onto the copper sleeve 3 in a planar flow pattern, the rapid cooling effect at the copper sleeve 3 forms amorphous ribbons. The above structural principle is easily understood by those skilled in the art based on existing known technologies and will not be elaborated further here.

[0028] A water distribution carrier 4 is provided between the copper sleeve 3 and the main shaft 2, forming a cooling chamber 31 between the water distribution carrier 4 and the copper sleeve 3. Cooling water exchanges heat with the copper sleeve 3 in the cooling chamber 31 to achieve a cooling effect. One end of the main shaft 2 is a water inlet 22 and the other end is a water outlet 23. The middle part of the main shaft 2 is provided with several circumferentially distributed water inlet holes 24. The middle part of the water distribution carrier 4 is provided with a water inlet channel 41 connecting the middle part of the cooling chamber 31 and the water inlet holes 24. The cooling water supplied by the water inlet 22 reaches the cooling chamber 31 after passing through the water inlet holes 24 and the water inlet channel 41.

[0029] The water distribution carrier 4 in this embodiment includes a diversion ring 5 fixedly connected to the inner side of the copper sleeve 3, forming a cooling cavity 31 between the diversion ring 5 and the copper sleeve 3. Furthermore, a cooling groove is provided on the inner circumferential surface of the copper sleeve 3, forming the cooling cavity 31 between the cooling groove and the outer circumferential surface of the diversion ring 5. In practical applications, fins or similar materials can be added to the cooling groove to increase the heat exchange area and improve cooling capacity. A water inlet guide 6 is fixedly connected between the middle of the diversion ring 5 and the main shaft 2. The middle of the diversion ring 5 has a main water inlet port 51 communicating with the cooling cavity 31. The water inlet guide 6 has a water inlet channel 61 connecting the main water inlet port 51 and the water inlet hole 24. The main water inlet port 51 and the water inlet channel 61 together form the water inlet channel 41.

[0030] The water distribution carrier 4 has a shaft end water outlet channel 43 on the side of the water inlet channel 41 near the water outlet end 23, and a seat end water outlet channel 42 on the side of the water inlet channel 41 near the water inlet end 22. The shaft end water outlet channel 43 and the seat end water outlet channel 42 are respectively connected to the corresponding portions of the cooling chamber 31. The cooling water entering the cooling chamber 31 flows to the shaft end water outlet channel 43 and the seat end water outlet channel 42 respectively, thus forming two water outlets.

[0031] The main shaft 2 is provided with several shaft end water outlet holes 25 that are connected to the shaft end water outlet channel 43. The water outlet is ultimately connected by the water outlet end 23. A water inlet / outlet partition 26 is provided on the main shaft 2 between the shaft end water outlet hole 25 and the water inlet hole 24. Preferably, a water inlet guide protrusion 27 is integrally provided on the end face of the water inlet / outlet partition 26 near the water inlet end 22. The water inlet guide protrusion 27 is gradually increased in height along the direction close to the center of the main shaft 2, thereby guiding the water flow in the main shaft 2 and reducing the resistance along the way.

[0032] The base 1 is fixedly provided with a seat end water outlet tank 9 that is rotatably and sealingly connected to the water distribution carrier 4. The water distribution carrier 4 is provided with a seat end water outlet hole 44 that connects the inner cavity of the seat end water outlet tank 9 and the seat end water outlet channel 42. The seat end water outlet tank 9 is provided with a seat end water outlet 91. The water outlet of this channel ultimately relies on the seat end water outlet tank 9 to form a water outlet connection.

[0033] The water outlet tank 9 described in this embodiment includes a water outlet tank body surrounding the main shaft 2. The side wall of the water outlet tank body near the water inlet end 22 is rotatably connected to the main shaft 2 in a sealed manner. A rotatable connection port coaxially arranged with the main shaft 2 is provided on the side wall of the water outlet tank body near the water distribution carrier 4. A dynamic sealing structure 92, capable of forming a seal with the water distribution carrier 4, is installed on the water outlet tank body at the rotatable connection port. The water outlet hole 44 at the seat end communicates with the rotatable connection port. Alternatively, the water outlet tank 9 can be an annular tank body surrounding the main shaft 2. In this case, an inner ring and an outer ring dynamic sealing structure 92 should be provided between the rotatable connection port and the water distribution carrier 4. The dynamic sealing structure 92 can be implemented using mechanical seals, etc., which are readily available to those skilled in the art based on known technologies and will not be elaborated further here.

[0034] A seat end water outlet pressure cap 7 is fixedly and sealed between the flow divider ring 5 and the main shaft 2, located on the side of the water inlet guide 6 near the water inlet end 22. A seat end water outlet guide channel 71 is formed between the seat end water outlet pressure cap 7 and the water inlet guide 6. The flow divider ring 5 is provided with several seat end water outlet flow holes 52 connecting the cooling chamber 31 and the seat end water outlet guide channel 71. The seat end water outlet flow holes 52 and the seat end water outlet guide channel 71 constitute the seat end water outlet channel 42. The space of the seat end water outlet guide channel 71 is obtained by directly sealing it with a pressure cap, which simplifies the processing of the water channel structure.

[0035] Similarly, a shaft end water outlet pressure cap 8 is fixedly and sealed between the flow divider ring 5 and the main shaft 2, located on the side of the water inlet guide 6 near the water outlet end 23. The shaft end water outlet pressure cap 8 and the water inlet guide 6 form a shaft end water outlet guide channel 81. The flow divider ring 5 is provided with a plurality of shaft end water outlet diversion holes 53 that connect the cooling chamber 31 and the shaft end water outlet guide channel 81. The shaft end water outlet diversion holes 53 and the shaft end water outlet guide channel 81 constitute the shaft end water outlet channel 43.

[0036] The water outlet cap 7 described in this embodiment includes a water outlet cap body 72 fixedly disposed between the diverter ring 5 and the main shaft 2. An inner water outlet support ring 73 is integrally provided on the water outlet cap body 72 near the edge of the main shaft 2, which can press against the water inlet guide body 6. Several outer water outlet support bodies 74 are integrally provided on the water outlet cap body 72 near the inner wall of the diverter ring 5, which can press against the water inlet guide body 6. A water outlet hole 44 is provided on the water outlet cap body 72 radially outside the inner water outlet support ring 73. Through the inner and outer ring support structures, the space of the water outlet guide channel 71 is supported while the water inlet guide body 6 is axially limited.

[0037] Similarly, the shaft end water outlet cap 8 includes a shaft end water outlet cap body 82 fixedly disposed between the diverter ring 5 and the main shaft 2. The shaft end water outlet cap body 82 has at least two rings of shaft end water outlet support rings 83 arranged radially along the main shaft 2, which can press against the water inlet guide 6. Each shaft end water outlet support ring 83 is provided with a water outlet hole 84 for water to flow through. The outer ring of the shaft end water outlet support ring 83 also adopts the form of a support block, and a water outlet gap is formed between adjacent support blocks. The inner ring of the shaft end water outlet support ring 83 also adopts a complete ring structure, and several radial through holes are opened on the complete ring structure to form water outlet holes. In this way, the shaft end water outlet cap 8 and the seat end water outlet cap 7 can easily form similar external structures, which facilitates uniform material cutting and processing.

[0038] Preferably, a water outlet guide cavity 93 is provided on the base 1 below the water outlet tank 9 at the base end, and the water outlet 91 at the base end is connected to the water outlet guide cavity 93 at the base end; the water outlet guide cavity 93 at the base end extends below the water inlet end 22, and a water outlet connection port 94 is provided on the side wall of the water outlet guide cavity 93 at the base end below the water inlet end 22. This directs the water outlet from the base end to the water inlet end 22, avoiding the high-temperature environment at the molten steel injection point and ensuring long-term use of the pipeline.

[0039] In this embodiment, the cooling water supplied by the inlet end 22 enters the cooling chamber 31 through the inlet channel 41 for cooling. After cooling, the water is discharged through two channels: the seat end outlet channel 42 and the shaft end outlet channel 43. Therefore, in addition to water exiting from the outlet end 23 of the spindle 2, this embodiment also increases the water outlet path by utilizing the seat end outlet tank 9 set on the machine base 1. Furthermore, the water distribution structure with water entering from the middle and exiting from both sides at the water distribution carrier 4 eliminates the problem of water distribution channel intersection. Therefore, both the inlet and outlet channels can have more space for installation. This allows this embodiment to overcome the limitations of the crystallizer structure volume and achieve a large flow of cooling water, which is beneficial to improving the cooling capacity of the copper sleeve 3. In addition to the water distribution carrier 4, this embodiment mainly adds a seat end outlet tank 9, and the overall structure is still compact, which is beneficial for installation within the limited space on the crystallizer.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
