A plurality of heating units are embedded in the heat conducting plate on the side facing the outer trough. A gap is reserved between the heat conducting plate and the trapezoidal guide bars. A fastening bolt that can be threadedly connected to the trapezoidal guide bars is movably passed through the heat conducting plate.

[0007] The outer tank is provided with a temperature control component electrically connected to the heating unit.

[0008] Optionally, the temperature control component includes a controller and a plurality of temperature sensors embedded in the outer tank body.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0023] It should be noted that if there are directional indications (such as up, down, bottom, top, etc.) involved in this embodiment, the directional indication is only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly. The terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. Unless otherwise clearly specified and defined, the terms "set", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be a communication between the two elements. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0024] like Figures 1-4 As shown, a heatable casting flow trough structure includes an inner trough body 1 and an outer trough body 2 attached to the outside of the inner trough body 1; wherein, the bottom of the outer trough body 2 is slidably connected to a heat conducting plate 4 through a plurality of groups of trapezoidal guide bars 3, and a plurality of groups of heating units 5 are embedded in the heat conducting plate 4 facing the side of the outer trough body 2, a gap is reserved between the heat conducting plate 4 and the trapezoidal guide bar 3, and a fastening bolt 6 that can be threadedly connected to the trapezoidal guide bar 3 is movably penetrated on the heat conducting plate 4; a temperature control component electrically connected to the heating unit 5 is provided on the outer trough body 2.

[0025] The casting launder in this technical solution is convenient for removal, replacement, and maintenance of the heating unit 5 by embedding the heating unit 5 in the outer tank body 2. At the same time, the heat generated by the heating unit 5 is conducted through the heat conducting plate 4. After being tightened by the fastening bolts 6, the heat conducting plate 4 can be tightly fitted with the outer tank body 2, allowing heat to be evenly conducted to the outer tank body 2 and the inner tank body 1, thereby uniformly heating the casting launder and maintaining the temperature of the molten metal in the launder.

[0026] The above, such as Figure 4 As shown, the temperature control assembly includes a controller and several temperature sensors 7 embedded in the outer tank body 2. The temperature sensors 7 are arranged in a linear array, and the temperature-sensing side of the temperature sensors 7 is attached to the outer tank body 2. This allows the temperature sensors 7 to monitor the real-time temperature of various locations on the outer tank body 2. The values ​​fed back by the temperature sensors 7 reflect the temperature at various locations on the inner tank body 1. The controller can receive the feedback signals from each temperature sensor 7 and adjust the output power of the heating unit 5 in the corresponding area in a targeted manner to ensure that the temperature of the molten metal is always within the appropriate range.

[0027] As mentioned above, the heating unit 5 is a device such as a heating rod or a heating plate in the prior art, which can control the output power and thus adjust the heating temperature; the controller is an electronic component commonly used in the prior art, which can receive the real-time temperature feedback from the temperature sensor 7, and can control the heating unit 5 to adjust the output power according to the real-time temperature value.

[0028] Further, such as Figure 1 、 Figure 2 As shown, both sides of the inner tank body 1 are provided with a first circular fold 101, and both sides of the outer tank body 2 are provided with a second circular fold 201 that can be slidably embedded in the first circular fold 101. The inner tank body 1 and the outer tank body 2 can be attached together through the sliding connection of the first circular fold 101 and the second circular fold 201, which has a simple structure and helps reduce production costs.

[0029] As mentioned above, a heat conducting layer is provided between the inner tank body 1 and the outer tank body 2 , and the heat conducting layer is made of heat conducting silica gel with good thermal conductivity, etc., which can effectively increase the heat conduction efficiency between the inner tank body 1 and the outer tank body 2 .

[0030] Furthermore, a wear-resistant layer is laid on the inner side of the inner tank body 1. The wear-resistant layer is a wear-resistant protective layer formed by spraying metal materials or alloys such as chromium, nickel, tungsten, molybdenum, iron, etc. onto the surface of the inner tank body 1 by spraying or spark spraying. It can make the surface of the inner tank body 1 wear-resistant, impact-resistant, corrosion-resistant and resistant to high-temperature environments, and can effectively increase the service life of the inner tank body 1.

[0031] In this technical solution, the cross-section of the inner tank body 1 is trapezoidal, which facilitates the flow of molten metal; the inner tank body 1 and the outer tank body 2 are both integral sheet metal parts, which can be stamped from stainless steel plates or titanium alloy plates, with a simple structure and low cost; the heat conduction plate 4 is an aluminum alloy plate with good thermal conductivity.

[0032] Working Principle: Before the inner and outer tank bodies 1 and 2 are slid together, a heat-conducting layer can be applied to the inner or outer tank body 1 or 2 to increase the heat conduction efficiency between the inner and outer tank bodies 1 and 2. At the same time, the heating unit 5 is attached to the outer tank body 2 via a heat-conducting plate 4. The heat-conducting plate 4 is tightly fitted to the outer tank body 2 via fastening bolts 6, allowing the heat generated by the heating unit 5 to be evenly transferred to the outer and inner tank bodies 2, thereby uniformly heating the casting launder and maintaining the temperature of the molten metal in the casting launder.

[0033] At the same time, the temperature sensor 7 can monitor the temperature of the molten metal in real time and transmit the temperature signal to the controller. The controller can accurately control the temperature of the molten metal by adjusting the output power of the heating unit 5 according to a preset temperature range.

[0034] The above description is based on the ideal embodiment of the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
