Description

Technical Field

[0001] This invention relates to an amorphous crystallizer, and more particularly to an amorphous crystallizer with a balanced water path. Background Technology

[0002] Amorphous crystallizers are used to produce amorphous ribbon. During the production process, 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 an amorphous ribbon. In this production process, the cooling effect of the crystallizer directly determines the product quality of the amorphous ribbon. The design of the crystallizer's cooling water circuit is crucial to its cooling rate. Furthermore, the water flow rate and the balance of water distribution within the circuit are the main considerations in designing the crystallizer's water circuit.

[0003] Currently used amorphous crystallizers, due to structural size limitations, employ cooling water circuits with water entering from one end of the spindle and exiting from the other. This type of cooling water circuit generally suffers from the following problems: First, the water inlet and outlet channels within the crystallizer can only be designed in a cross pattern, which means the cooling water flow path cannot be optimally designed, limiting the overall flow rate and cooling capacity. Second, although existing technologies include structures with water entering from the middle of the copper sleeve and exiting from both ends, these designs still involve cross-channels, and the lengths of the water outlet paths at the two ends differ. This leads to uneven water return at both ends, ultimately resulting in different cooling effects on both sides of the crystallizer surface, thus affecting product quality. Therefore, further improvements are needed to the cooling water circuits of amorphous crystallizers to address these issues. Summary of the Invention

Detailed Implementation

[0028] 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.

[0029] like Figures 1 to 12 As shown, the balanced water-channel 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, the rapid cooling effect at the copper sleeve 3 forms an amorphous thin strip. 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.

[0030] In this embodiment, both ends of the main shaft 2 are water inlet ends 22. The middle part of the main shaft 2 is provided with several circumferentially distributed water inlet holes 23. The inner side of the copper sleeve 3 is fixedly connected to a flow equalization ring 4. A cooling cavity 31 is formed between the flow equalization ring 4 and the copper sleeve 3. The middle part of the flow equalization ring 4 is provided with several water inlet flow equalization holes 41 that communicate with the cooling cavity 31. A water inlet guide 5 is fixedly connected between the middle part of the flow equalization ring 4 and the middle part of the main shaft 2. The water inlet guide 5 is provided with a water inlet guide channel 51 that communicates with the water inlet holes 23 and the water inlet flow equalization holes 41.

[0031] Cooling water entering from the two inlet ends 22 passes through the inlet hole 23, the inlet flow guide channel 51, and the inlet flow equalization hole 41 before entering the cooling chamber 31. The high thermal conductivity of the copper sleeve 3 enables rapid cooling of the molten steel. The inlet flow guide 5 serves both as a support structure connecting the copper sleeve 3 and the flow equalization ring 4 to the main shaft 2, and as a carrier providing the inlet flow guide channel 51, thus making this embodiment structurally compact.

[0032] The water inlet guiding channel 51 described in this embodiment includes a water inlet collecting ring cavity 52 that communicates with several water inlet holes 23 and a water inlet distributing ring cavity 53 that communicates with several water inlet equalizing holes 41. Several water inlet guiding holes 54 are connected between the water inlet collecting ring cavity 52 and the water inlet distributing ring cavity 53, and these water inlet guiding holes 54 are also circumferentially distributed. After water collection, guiding, and distributing, the incoming water can flow evenly through the water inlet equalizing holes 41, improving the uniformity of the incoming water flow. The water inlet guiding body 5, while achieving uniform water distribution to the water inlet equalizing holes 41, utilizes a portion of the wall of the water inlet guiding holes 54 to form an integral component, which is more convenient for processing and installation compared to a split structure.

[0033] The inner wall of the copper sleeve 3 is provided with a cooling groove 32, and the cooling groove 32 and the outer ring surface of the flow equalization ring 4 form the cooling cavity 31. The cooling groove 32 is provided with a plurality of cooling fins 33 integrally formed with the copper sleeve 3, and a cooling flow guide gap 34 is formed between adjacent cooling fins 33. The arrangement of the cooling fins 33 can increase the contact area between the copper sleeve 3 and the cooling water, thereby improving the heat conduction effect. Furthermore, the arrangement of the cooling groove 32 and the cooling fins 33 on the copper sleeve 3 can improve the heat conduction effect while making it easy to assemble the copper sleeve 3 and the flow equalization ring 4 into a single unit.

[0034] At least one cooling guide opening 35 is provided on the cooling fin 33 between the water inlet equalization hole 41 and the water outlet equalization hole 43. The cooling guide opening 35 allows water to flow between adjacent cooling guide gaps 34, which makes the water flow at each cooling guide gap 34 more uniform and improves the cooling uniformity of the copper sleeve 3.

[0035] The flow equalization ring 4 is provided with a flow equalization ring cavity 42 at one end of the plurality of water inlet equalization holes 41 near the copper sleeve 3. The flow equalization ring cavity 42 makes the cooling water entering the cooling chamber 31 through the water inlet equalization holes 41 enter each of the cooling guide gaps 34 more evenly, thereby further improving the cooling uniformity of the copper sleeve 3.

[0036] The flow equalization ring 4 is provided with a plurality of water outlet equalization holes 43 on both sides of the plurality of water inlet equalization holes 41, which are connected to the cooling chamber 31. The cooling water entering through the water inlet equalization holes 41 is heat-exchanged through the cooling flow guide gaps 34 and then flows out from the corresponding water outlet equalization holes 43. Preferably, the flow equalization ring 4 is provided with a flow equalization collecting ring cavity 44 at one end of the plurality of water outlet equalization holes 43 on the same side near the copper sleeve 3. The flow equalization collecting ring cavity 44 balances the water flow pressure at each of the cooling flow guide gaps 34, further ensuring the uniformity of cooling at the copper sleeve 3.

[0037] Two outlet guide caps 6 are fixedly installed between the flow equalization ring 4 and the main shaft 2, respectively located on both sides of the inlet guide fluid 5. An outlet guide channel 61 is formed between the outlet guide cap 6 and the inlet guide fluid 5, communicating with the corresponding outlet flow equalization hole 43. The water from the outlet flow equalization holes 43 on each side flows into the corresponding outlet guide channel 61. The outlet guide cap 6 also serves as both a support structure for connecting the copper sleeve 3 and the flow equalization ring 4 to the main shaft 2, and a barrier structure that surrounds the outlet guide channel 61 with the inlet guide fluid 5, so that the outlet channel can be set up in a compact structure in this embodiment.

[0038] The outlet guide cap 6 includes an outlet guide cap body 62 disposed between the flow equalization ring 4 and the main shaft 2. An inner support ring 63 is integrally provided on the outlet guide cap body 62 near the edge of the main shaft 2, which can press and seal against the inlet guide fluid 5. Several circumferentially arranged outer support bodies 64 are provided on the outlet guide cap body 62 near the flow equalization ring 4, and the outer support bodies 64 can press against the inlet guide fluid 5. The outlet guide cap body 62, with its inner and outer supports, creates space for water flow between itself and the inlet guide fluid 5, ensuring reliable relative positioning. Furthermore, the annular structure of the inner support ring 63 can block the outlet guide channel 61 near the main shaft 2, and the point support of the outer support bodies 64 does not affect the normal flow of water within the outlet guide channel 61.

[0039] In this embodiment, sleeve pressure rings 7 are bolted to both ends of the flow equalization ring 4. Each sleeve pressure ring 7 has a pressure sleeve portion 71 that can press against the end face of the copper sleeve 3 and a pressure cover portion 72 that can press against the water outlet guide cover 62. The sleeve pressure rings 7 ensure that the copper sleeve 3, the inlet guide fluid 5, and the two water outlet guide covers 6 are integrally fixed relative to the axial direction of the flow equalization ring 4. Furthermore, in this embodiment, the main shaft 2 is provided with inlet and outlet mounting bosses 24 for mounting the inlet guide fluid 5 and the two water outlet guide covers 6. Water outlet cover pressure rings 8 are mounted on the main shaft 2 at both ends of the inlet and outlet mounting bosses 24, and are fixedly connected to the water outlet guide covers 6 near the edge of the main shaft 2. Thus, the copper sleeve 3, the flow equalization ring 4, the inlet guide 5, the two outlet guide pressure caps 6, and the two outlet cap pressure rings 8 form an integrated inlet and outlet water circuit structure. This integrated structure relies on the inlet and outlet mounting bosses 24 to form axial limiting. Preferably, the outlet cap pressure ring 8 is keyed to the main shaft 2, so that the integrated structure can rotate synchronously with the main shaft 2.

[0040] On the base 1, a water collection box 9 is fixedly provided on the outside of each of the water outlet guide cover 6. The water collection box 9 is pressed onto the water outlet guide cover 6 on the corresponding side and is sealed and rotatably connected to the water outlet guide cover 6 on the corresponding side. The sealed rotatable connection here adopts a mechanical seal. This kind of sealing structure is easily obtained by those skilled in the art in combination with conventional technical means, and will not be described in detail here.

[0041] The water outlet guide cap 6 is provided with a water outlet hole 65 that connects to the inner cavity of the water outlet collection box 9, and the water outlet collection box 9 is provided with a water outlet 91. By setting the water outlet collection box 9 on the base 1 and sealingly rotating it with the water outlet guide cap 6 on the corresponding side, the water outlet connection is finally realized.

[0042] Preferably, the base 1 is provided with a water outlet guiding cavity 92 below each of the water outlet collection boxes 9. The water outlet 91 is connected to the water outlet guiding cavity 92. The water outlet guiding cavity 92 extends to the lower part of the corresponding water inlet end 22. The water outlet guiding cavity 92 has a water outlet connection port 93 on its cavity wall below the water inlet end 22. By adding the water outlet guiding cavity 92 to the volume of the base 1, the water outlet can extend to the lower part of the water inlet end 22 for water outlet connection, avoiding the high-temperature working environment near the copper sleeve 3 and ensuring the reliability of the pipeline.

[0043] In this embodiment, a cooling water inlet is formed in the middle of the main shaft 2, and cooling water outlets are formed on both sides of the inlet guide 5. The outlet connection is then formed by the outlet collection box 9 installed on the base 1. The overall inlet and outlet structure is symmetrical, and the inlet and outlet water paths are balanced. There are no branching water paths, and compared to existing structures with branching water paths, there is more space for both the inlet and outlet water channels, significantly widening the water flow path. Furthermore, this embodiment forms a cooling water flow path with water entering from both ends of the main shaft 2 and exiting from the two outlet collection boxes 9, thus significantly increasing the cooling water flow rate. Compared to existing technologies, the branching water path design in this embodiment is mainly integrated between the copper sleeve 3 and the main shaft 2. In addition, the main difference is the addition of the outlet collection box 9 on the base 1. The overall structure remains compact, facilitating installation within the limited space of the crystallizer. The balanced inlet and outlet water paths and the increased cooling water flow rate enable this embodiment to achieve better cooling capacity.

[0044] 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. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
