Description

Technical Field

[0001] This application relates to the field of submersible nozzle technology, and in particular to a baking apparatus suitable for submersible aluminum carbon nozzles. Background Technology

[0002] In continuous casting processes, submerged entry nozzles are key functional refractory materials connecting the ladle and the crystallizer. Their functions include preventing secondary oxidation of molten steel, controlling steel flow, and promoting the flotation of inclusions. In particular, alumina-carbon submerged entry nozzles must undergo thorough preheating before use to remove internal moisture, preventing cracks or bursts caused by rapid heating, and to bring them to a temperature close to that of molten steel to prevent solidification within the nozzle.

[0003] Currently, the baking of submerged sprue nozzles is generally carried out by directly spraying flames from a baking gun. Existing baking methods mostly have the following drawbacks: Loading and unloading operations usually require manual labor or the use of simple tools to move the heavy nozzle to the baking position, placing workers in close contact with high-temperature equipment and intense flames, which can easily cause burns and other safety accidents; open or semi-open baking environments result in significant heat loss and low energy efficiency. Furthermore, the uncontrollable flame flow can lead to uneven heating of the nozzle, affecting baking quality and even damaging the nozzle due to localized overheating; different casting processes use significantly different types and sizes of submerged sprue nozzles. Existing baking racks often have fixed support structures, making it impossible to quickly adapt to different nozzle models, requiring the preparation of multiple baking fixtures, which is cumbersome and affects production efficiency; the heat and exhaust gases generated during the baking process directly diffuse into the workshop environment, worsening the working conditions for operators.

[0004] Therefore, there is an urgent need for a dedicated baking device that can automate loading and unloading, improve baking uniformity and safety, and quickly adapt to different types of sprue nozzles. Summary of the Invention

[0005] The purpose of this application is to provide a baking apparatus suitable for immersion aluminum carbon nozzles in order to solve the above-mentioned problems, which can significantly improve operational safety, improve baking quality and efficiency, and enhance the versatility and flexibility of the equipment.

[0006] This application achieves the above objectives through the following technical solutions: A baking apparatus suitable for immersion aluminum carbon nozzles, comprising: Base; A heating assembly includes a heating cylinder and a baking gun fixed to the base. The heating cylinder is made of heat-insulating material and has an open top, forming a baking cavity inside. The nozzle of the baking gun extends into the baking cavity. An air supply assembly includes an air pump and an air pipe, one end of which is connected to the bottom of the heating cylinder and the other end of which is connected to the air pump; A sprue transfer mechanism includes a tray for supporting an immersion nozzle, a horizontal drive unit for driving the tray to move horizontally, and a lifting drive unit for driving the tray to lift. The tray is provided with an insertion hole configured to allow the narrow end of the immersion nozzle to be inserted and prevent its wide end from passing through, so that the immersion nozzle is suspended on the tray.

[0007] In some embodiments, the heating assembly further includes a cylinder frame fixed to the base and supporting the heating cylinder, and the baking gun is mounted on the cylinder frame.

[0008] In some embodiments, the horizontal drive unit includes: The bracket is fixed to the base; The slide bar and rack are fixed to the bracket; A slider that slides in conjunction with the slide rod; The support plate is fixedly connected to the slider; A horizontal movement drive motor is mounted on the support plate, and a gear that meshes with the rack is connected to the output shaft of the horizontal movement drive motor.

[0009] In some embodiments, the lifting drive unit includes: A lifting drive motor fixed to the support plate; A vertically arranged screw that is driven to rotate by the lifting drive motor; An internal threaded sleeve that is screwed to the screw; A connecting rod is fixedly connected to the internal threaded sleeve, and the end of the connecting rod facing away from the threaded sleeve is detachably connected to the support plate.

[0010] In some embodiments, the lifting drive unit further includes a guide frame fixedly connected to the lifting drive motor, and the connecting rod is slidably engaged with the guide frame.

[0011] In some embodiments, the tray and the connecting rod are detachably connected by fasteners.

[0012] In some embodiments, the tray is L-shaped, with the insertion hole provided on its horizontal wall and its vertical wall connected to the connecting rod.

[0013] In some embodiments, the tray is a replaceable component and has various specifications. Different specifications of trays have different hole sizes and / or shapes to adapt to different models of immersion nozzles.

[0014] In some embodiments, the number of slide bars is at least two, arranged in parallel at intervals.

[0015] In some embodiments, the heating cylinder has a circular or rectangular cross-section.

[0016] Compared with existing technologies, the immersion-type aluminum carbon nozzle baking device provided in this application can achieve the following beneficial technical effects: through the horizontal movement and lifting motion of the pallet, the automated picking, placing and transferring of the immersion nozzle is realized, keeping the operator completely away from the high-temperature area and open flame of the baking station, fundamentally eliminating safety hazards such as burns; adopting a top-opening heating cylinder structure made of heat-insulating material, it effectively gathers heat and reduces heat loss, forming a highly efficient baking chamber with high energy utilization; combined with the air pump that introduces air at the bottom, it optimizes the combustion environment, making the flame burn more completely and the heat distribution more even, thereby ensuring the uniformity and thoroughness of the nozzle baking; the pallet and the drive mechanism are detachably connected, and various pallets with different sizes of insertion holes can be pre-prepared. When changing the sprue type, only the corresponding support plate needs to be replaced, which realizes rapid changeover and co-line production of different types of immersion sprues, greatly improving the utilization rate of equipment and the flexibility of production organization; horizontal movement is achieved through gear and rack transmission, and lifting movement is achieved through screw and nut pair, and a guide frame and slide block mechanism are set up to ensure transmission accuracy and smooth operation, ensuring that the sprue can be accurately sent into or taken out of the predetermined position in the heating cylinder.

[0021] like Figure 1-3 As shown, a baking device suitable for immersion aluminum carbon nozzles includes a base 8, a heating component, an air supply component, and a nozzle transfer mechanism.

[0022] The base 8 provides the basic support for the entire device, and it has a flat mounting surface on which all other components are directly or indirectly fixed.

[0023] The heating assembly mainly includes a heating cylinder 1, a cylinder frame 2, and a heating torch 3. The heating cylinder 1 is preferably made of refractory and heat-insulating material, with an open top and an internal cavity for accommodating and heating the immersion nozzle. The cylinder frame 2 is fixedly mounted on a base 8 to support and secure the heating cylinder 1. The heating torch 3 is a conventional gas-fired torch, fixedly mounted on the cylinder frame 2 via a bracket, with its nozzle inserted obliquely or vertically into the center of the cavity of the heating cylinder 1 to uniformly heat the nozzle.

[0024] The air supply assembly includes an air pump 5 and an air pipe 4. One end of the air pipe 4 is connected to the bottom side wall or bottom wall of the heating cylinder 1, and the other end is connected to the air outlet of the air pump 5. When the air pump 5 is started, air can be continuously or intermittently blown into the bottom of the heating cylinder 1. On the one hand, this provides oxygen for the flame combustion of the heating gun 3, improving combustion efficiency and temperature. On the other hand, the airflow helps to form a circulation inside the cylinder, making the heat distribution more uniform.

[0025] The sprue transfer mechanism is the core of this project, used for automatically grabbing, transferring, placing, and retrieving submersible sprues. This mechanism mainly includes a pallet 6, a horizontal drive unit, and a lifting drive unit.

[0026] The support plate 6, in this embodiment, serves as the sprue support and is generally L-shaped. An insertion hole 7 is provided on its horizontal wall. This insertion hole 7 is designed to allow the smaller diameter end (usually the lower end) of the immersion sprue to be baked to be inserted, but its larger diameter end (usually the flange-like structure at the upper end) cannot pass through, thus allowing the sprue to be stably suspended on the support plate 6. The vertical wall of the support plate 6 is used for connection to the drive unit. Importantly, the support plate 6 is designed as a quick-change component; by preparing a series of support plates 6 with different sized insertion holes 7, different models of sprues can be flexibly adapted.

[0027] The horizontal drive unit is used to drive the pallet 6 and its sprue nozzles to move horizontally, realizing the transfer between the loading / unloading position and the baking position (i.e., directly above the heating cylinder 1). The horizontal drive unit includes a bracket 9, slide rods 10, sliders 11, a support plate 12, a horizontal movement drive motor 13, a gear 21, and a rack 14. The bracket 9 is fixed to the base 8. Two parallel slide rods 10 are fixedly mounted on the bracket 9. The slider 11 is slidably engaged with the slide rods 10. The support plate 12 is fixedly connected to the slider 11, so it can be driven by the slider 11 to slide horizontally along the direction of the slide rods 10. The horizontal movement drive motor 13 is fixedly mounted on the support plate 12, and its output shaft is equipped with a gear 21. A rack 14, which is parallel to the slide rods 10, is fixedly mounted on the bracket 9 and meshes with the gear 21. When the horizontal movement drive motor 13 is working, the drive gear 21 rotates. Since the rack 14 is fixed, the gear 21 will roll along the rack 14, thereby driving the entire support plate 12 and all its components to move precisely along the slide bar 10.

[0028] The lifting drive unit is used to drive the tray 6 and its water inlet to move vertically up and down, enabling the water inlet to be placed into or removed from the heating cylinder 1. The lifting drive unit mainly includes a lifting drive motor 17, a screw 18, an internal threaded sleeve 19, a connecting rod 15, a guide frame 20, and fasteners 16. The lifting drive motor 17 is fixedly installed on the cantilevered portion of the support plate 12. The screw 18 is vertically positioned, with its upper end fixedly connected to the output shaft of the lifting drive motor 17. The internal threaded sleeve 19 is threadedly engaged with the screw 18. The upper end of the connecting rod 15 is fixedly connected to the internal threaded sleeve 19, and its lower end is detachably connected to the vertical wall of the tray 6 via fasteners 16 (such as bolts, pins, etc.). The guide frame 20 is fixedly installed on the housing of the lifting drive motor 17, and has a guide hole or guide rail inside. The connecting rod 15 passes through this guide and slides within it, ensuring that the connecting rod 15 and the tray 6 can only move vertically up and down, and will not rotate with the screw 18. When the lifting drive motor 17 is working, it drives the screw 18 to rotate, thereby driving the internal threaded sleeve 19 to drive the connecting rod 15 and the support plate 6 to rise and fall smoothly along the guide frame 20.

[0029] The working process for this application is as follows: Initially, the sprue transfer mechanism is located at the loading station outside the heating cylinder 1. The operator or the sprue robot inserts the narrow end of the immersion sprue into the insertion hole 7 of the corresponding model of the mounting plate 6, and the sprue is suspended on the mounting plate 6 by its own weight. Subsequently, the horizontal movement drive motor 13 starts, driving the support plate 12 to move directly above the heating cylinder 1 through the meshing transmission of gear 21 and rack 14. After reaching the predetermined position, the horizontal movement stops. Next, the lifting drive motor 17 starts and rotates forward to drive the screw 18, which in turn drives the support plate 6 to descend through the threaded joint, smoothly sending the suspended water inlet into the baking position inside the heating cylinder 1. Next, start the heating gun 3 and air pump 5 to heat and bake the sprue. After baking, stop the heating gun 3 and air pump 5. Then, the lifting drive motor 17 reverses to lift the sprue out of the heating cylinder 1. Afterwards, the horizontal movement drive motor 13 reverses to transfer the sprue to the initial unloading position. Finally, the operator or robotic arm removes the baked sprue, completing one work cycle. The entire process requires minimal human intervention, making it safe and efficient.
