Description

Technical Field

[0001] This utility model relates to the field of aluminum rod casting technology, specifically to a precision flow control system for an electronic flowmeter used in aluminum rod casting. Background Technology

[0002] Aluminum rod casting is a metal forming process in which molten aluminum is poured into a mold through a specific process, and then cooled and solidified to form an aluminum rod. It is a fundamental step in aluminum processing. Aluminum ingots that meet the purity standards or are alloyed are heated to a molten state above 660°C. After removing impurities and gases, the molten aluminum is poured into the mold cavity. The molten aluminum gradually cools and crystallizes within the mold, eventually forming an aluminum rod billet with a fixed cross-sectional shape and size, which can then be used for further processing such as extrusion and forging.

[0003] For example, the authorization announcement number "CN217798830U" is named an aluminum rod casting device. The aluminum rod casting device has the advantages of reducing the temperature rise of the fixed frame and the flipping frame and ensuring normal use. The existing aluminum rod casting device needs to melt aluminum into molten aluminum at high temperature and then pour the molten aluminum into the casting mold of the aluminum rod. The injection of molten aluminum needs to be precisely controlled. Conventional casting can only rely on manual experience to add molten aluminum, which may result in over- or under-filling. Over-filling can easily cause the high-temperature molten aluminum to overflow, while under-filling will result in a lower density of the final formed aluminum rod, affecting the quality. Therefore, it cannot meet the precise control requirements of the aluminum rod casting device. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing aluminum rod casting devices have the problem that overfilling can easily lead to the overflow of high-temperature molten aluminum, while underfilling will result in a lower density of the final formed aluminum rod, affecting the quality. Therefore, it is impossible to meet the precise control requirements of aluminum rod casting devices. The invention proposes an electronic flow meter precision flow control system for aluminum rod casting.

[0005] To achieve the above objectives, this utility model provides the following technical solution: Design a precision flow control system for an electronic flow meter used in aluminum rod casting, including a casting mold, a mold cover and a sealing ring. The mold cover is movably connected above the casting mold. The top of the mold cover is provided with an aluminum rod casting flow control structure. The inner side of the casting mold is provided with a high-temperature resistant sandwich structure.

[0006] Preferably, the aluminum rod casting flow control structure includes an inlet hole and a filling tube. A plurality of inlet holes are fixedly opened at the top of the mold cover, and a plurality of filling tubes are fixedly connected above the inlet holes. A solenoid valve is fixedly installed on the inner side of the plurality of filling tubes, and a connecting flange is fixedly connected to the top of the plurality of filling tubes. A connecting pipe is fixedly connected above the connecting flange, and an electronic flow meter is fixedly installed between the filling tube and the connecting pipe.

[0007] In this setup, the top connecting pipe is connected to the high-temperature molten aluminum container pipeline. Molten aluminum flows along the filling connecting pipe to the lower filling pipe. During the flow, an electronic flow meter continuously measures the flow rate of the molten aluminum. The electronic flow meter is the existing core detection component, which collects molten aluminum flow data in real time. It is adapted to the measurement environment of high-temperature molten aluminum and is connected to a control module to receive the flow signal. After comparing it with the preset value, it outputs a command, which can realize automatic closed-loop regulation. When the electronic flow meter detects that the molten aluminum has reached the casting quantity, the solenoid valve below will quickly respond to the control command to adjust and cut off the internal pipeline of the filling pipe to control the flow rate. This achieves accurate measurement of the molten aluminum poured into the aluminum rod casting, reducing the possibility of too much or too little molten aluminum being poured in.

[0008] Preferably, the plurality of filling holes are distributed parallel to each other at equal intervals, and the solenoid valve is electrically connected to the electronic flow meter.

[0009] Preferably, the high-temperature resistant sandwich structure includes an anti-scalding layer and an isolation layer. The isolation layer is fixedly connected to the inner wall of the casting mold, the anti-scalding layer is fixedly connected to the outer wall of the casting mold, the high-temperature resistant layer is fixedly connected to the inner side of the isolation layer, and multiple positioning seats are fixedly provided on the inner side of the high-temperature resistant layer.

[0010] This design features a ceramic-based coating for the isolation layer, with aluminum oxide, zirconium oxide, and silicon nitride as the main components. It can withstand temperatures above 1200℃ and has high hardness. The anti-scalding layer is a stainless steel layer with an internal vacuum, so workers are less likely to be burned when they come into contact with the outer wall of the casting mold. The high-temperature resistant layer is a metal-ceramic composite layer, combining the toughness of metal and the high-temperature resistance of ceramic. It is prepared through processes such as plasma spraying, resulting in strong adhesion and a long service life. The positioning seat determines the chiseling positions of multiple forming cavities 4 to prevent the cast aluminum rod from shifting or deforming.

[0011] Preferably, the positioning seat has a molding cavity on its inner side, and the top of the plurality of molding cavities is connected to the lower end of the filling hole.

[0012] In this design, the forming cavity is cylindrical and closed when the mold cover is placed on top of the casting mold, facilitating the forming of the aluminum rod.

[0013] Preferably, a sealing ring is fitted onto the top of the outer wall of the casting mold, and the upper half of the sealing ring is movably connected to the outer wall of the mold cover.

[0014] This feature involves a sealing ring that is used to secure the connection between the casting mold and the mold cover, reducing the risk of molten aluminum overflow and potential hazards.

[0015] This utility model proposes a precise flow control system for aluminum rod casting using an electronic flow meter. The advantages are as follows: the top connecting pipe is connected to a high-temperature molten aluminum container pipe. Molten aluminum flows along the filling connecting pipe to the lower filling pipe. During this flow, the electronic flow meter continuously measures the flow rate of the molten aluminum. The electronic flow meter is a core detection component that collects molten aluminum flow data in real time, adapting to the high-temperature molten aluminum measurement environment. It is connected to a control module that receives flow signals, compares them with preset values, and outputs commands, enabling automatic closed-loop regulation. When the electronic flow meter detects that the molten aluminum has reached the required casting quantity, the lower solenoid valve quickly responds to the control command, adjusting and cutting off the internal pipe of the filling pipe to control the flow rate. This achieves precise metering of molten aluminum poured into the aluminum rod casting system, reducing the possibility of too much or too little molten aluminum being poured in.

It collects molten aluminum flow data in real time, is suitable for measuring high-temperature molten aluminum, and is connected to a control module (not marked in the figure) to receive the flow signal. After comparing it with the preset value, it outputs a command to realize automatic closed-loop regulation. When the electronic flow meter 55 detects that the molten aluminum has reached the casting quantity, the solenoid valve 53 below will quickly respond to the control command to adjust and cut off the internal pipe of the filling pipe 52 to control the flow. The connecting flange 54 is fixedly connected to the upper part of the connecting pipe 56, and the electronic flow meter 55 is fixedly installed between the filling pipe 52 and the connecting pipe 56.

[0021] Multiple injection holes 51 are distributed parallel to each other at equal intervals, and the solenoid valve 53 is electrically connected to the electronic flow meter 55.

[0022] The high-temperature resistant sandwich structure 6 includes an anti-scalding layer 61 and an isolation layer 62. The isolation layer 62 is a ceramic-based coating with aluminum oxide, zirconium oxide, silicon nitride, etc. as the main components. It can withstand temperatures above 1200℃ and has high hardness. The isolation layer 62 is fixedly connected to the inner wall of the casting mold 1. The anti-scalding layer 61 is fixedly connected to the outer wall of the casting mold 1. The anti-scalding layer 61 is a stainless steel layer with a vacuum inside, so that workers are not easily burned when they come into contact with the outer wall of the casting mold 1.

The high-temperature resistant layer 63 is a metal-ceramic composite layer, which combines the toughness of metal and the high-temperature resistance of ceramic. It is prepared by processes such as plasma spraying, which has strong adhesion and long service life. Multiple positioning seats 64 are fixedly provided on the inner side of the high-temperature resistant layer 63. The positioning seats 64 determine the chiseling position of multiple forming cavities 4 and prevent the cast aluminum rod from shifting and deforming.

[0023] The positioning seat 64 has a forming cavity 4 inside. The forming cavity 4 is a cylindrical opening. When the mold cover 2 is put on top of the casting mold 1, it is closed.

Multiple cavities for forming aluminum rods are vertically excavated on the inner side of the casting mold 1. The top connecting pipe 56 is connected to the high-temperature aluminum liquid container pipe. The aluminum liquid flows along the filling connecting pipe 56 to the lower filling pipe 52. During the flow, the electronic flow meter 55 continuously measures the flow rate of the aluminum liquid. The electronic flow meter 55 is the existing core detection component, which collects aluminum liquid flow data in real time. It is adapted to the measurement environment of high-temperature aluminum liquid and is connected to a control module (not marked in the figure) to receive the flow signal. After comparing it with the preset value, it outputs the command and can realize automatic closed-loop regulation. When the electronic flow meter 55 detects that the aluminum liquid has reached the casting quantity, the lower solenoid valve 53 will quickly respond to the control command to adjust and cut off the internal pipe of the filling pipe 52 to control the flow rate. This achieves accurate measurement of the aluminum liquid poured into the aluminum rod casting and reduces the situation of too much or too little aluminum liquid being poured in. The isolation layer 62 is a ceramic-based coating with aluminum oxide, zirconium oxide, silicon nitride and other main components. It can withstand high temperatures above 1200℃ and has high hardness. The anti-scalding layer 61 is a stainless steel layer with a vacuum inside, so that workers are not easily burned when they come into contact with the outer wall of the casting mold 1. The high temperature resistant layer 63 is a metal-ceramic composite layer, which combines the toughness of metal and the high temperature resistance of ceramic. It is prepared by plasma spraying and other processes, with strong adhesion and long service life.
