[0001] The utility model relates to the field of metallurgy, in particular to a titanium alloy product processing technology, in particular to an energy-saving titanium alloy electrode baking pit. Background Art

[0002] The rapid development of space exploration technology and civil aviation has led to an increasing demand for high-end titanium alloy products. The control of titanium alloy composition, especially the control of oxygen content, has always been a key point of concern. The conventional steps in the production of titanium alloy ingots are pressing and extruding electrodes and three vacuum consumable smeltings. The intermediate alloy used in pressing and extruding electrodes is easily affected by a humid environment, causing the electrode block to become damp and increase its oxygen content. Therefore, before smelting, it is necessary to take baking measures for the extruded electrodes at a fixed temperature for a certain period of time. However, the temperature of the heating furnace in the existing technology does not meet the baking requirements of the extruded electrodes, and its energy consumption is very huge. At present, there is a lack of equipment with a temperature range of room temperature to 100°C, which saves energy consumption and is suitable for baking titanium alloy electrodes. Summary of the Invention

[0003] The purpose of the utility model is to provide an energy-saving titanium alloy electrode baking pit, which is intended to solve the technical problem that the heating furnace in the prior art cannot meet the baking requirements of the extruded electrodes.

[0006] Furthermore, three groups of heating components are installed on both sides of the inner wall of the pit. The heating components include resistance wires, power supply accessories, and lead-out rods. The resistance wires are connected to the lead-out rods through the power supply accessories.

[0007] Furthermore, the heat radiation assembly includes a heat radiation steel plate, a fixing frame and a support frame.

[0017] The following is a further description of the present invention in conjunction with an embodiment. However, the present invention is not limited to the embodiment. All similar structures and similar variations of the present invention should be included in the scope of protection of the present invention. The use of directions such as up, down, front, back, left, and right in the present invention is only for the convenience of clear description and does not limit the technical solution of the present invention.

[0018] The utility model discloses an energy-saving titanium alloy electrode baking pit, which is mainly used for baking titanium alloy electrodes. The specific structure and working principle of the pit are described in detail below.

[0019] like Figure 1 As shown, the main body of the pit is made of concrete and fireproof heat-resistant bricks to form a pit body 1. The bottom of the pit body 1 is built with a heat-resistant brick concrete structure, on which there are material racks 2, which are several stainless steel rails perpendicular to the heating assembly for placing titanium alloy electrodes.

[0020] Three groups of heating components 4 are arranged on both sides of the inner wall of the pit body 1. Figure 2 As shown, the heating component includes a resistance wire 401, a power supply accessory 402, and a lead rod 403. The lead rod 403 is connected to an external power supply through a cable, and provides three-phase AC power to the resistance wire 401 through the power supply accessory 402 to generate heat.

[0021] Three heat radiation steel plates 5 are respectively provided on the outside of the heating component 4. The upper part of the heat radiation steel plate 5 is fixedly installed on the fixing frame 6, and the lower part is welded to the support frame 7. The support frame 7 is fixedly installed on the material rack 2, and the fixing frame 6 is installed on the support frame 7. The radiation steel plate 5, the support frame 7 and the fixing frame 6 are all made of stainless steel, and the fixing frame 6 and the support frame 7 form a frame.

[0022] A temperature sensor 9 is provided between each two adjacent groups of heating components 4. The temperature sensor 9 is connected to a temperature control and power regulation instrument 10 through a cable 8. The temperature control and power regulation instrument 10 controls the heating components 4 according to the internal temperature of the pit fed back by the temperature sensor 9 to maintain the temperature inside the pit.

[0023] In order to maintain the baking temperature, there is a movable top cover 11 on the top of the pit body 1. When it is necessary to put the titanium alloy electrode into the pit, the top cover 11 can be moved to expose the pit body. A ladder 3 is provided between the bottom of the pit body 1 and the ground to facilitate operators to enter the pit body to lift the electrode and maintain the facilities inside the pit.

[0024] Specifically, the resistance wire 401, power supply accessory 402, lead rod 403, heat radiation steel plate 5, temperature sensor 9, temperature control and power regulation instrument 10, etc. in this embodiment all adopt well-known solutions in the prior art, which are well understood by those skilled in the art and will not be repeated here.

[0025] The working process of the device is as follows:

[0026] Step 1: Hoist the titanium alloy electrode into the pit.

[0027] Move the top cover 11, hoist the titanium alloy extruded electrodes or the electrodes that have undergone consumable smelting on the ground onto the material rack 2, and then move the top cover 11 to the top of the pit body 1 to seal the entire pit body 1.

[0028] Step 2: Set the baking temperature

[0029] The baking temperature is set on the temperature control and power regulation instrument 10, and then the heating component 4 starts to generate heat, and the heat is transmitted to the pit body 1 through the heat radiation steel plate 5. Within 30 minutes, the temperature of the pit body 1 reaches the set temperature, and the electrode starts to be baked. During the baking process, the temperature sensor 9 monitors the temperature in the pit in real time and feeds back to the temperature control and power regulation instrument 10. The temperature control and power regulation instrument 10 controls the heating component 4 to maintain the temperature inside the pit at the set temperature.

[0030] Step 3: Remove the titanium alloy electrode from the pit

[0031] Move the top cover 11 and turn off the temperature control and power adjustment instrument 10. When the temperature in the pit drops to room temperature, the operator enters the bottom of the pit body 1 through the ladder 3, fixes the sling on the titanium alloy extruded electrode or the electrode that has undergone consumable smelting in the pit body 1, and then lifts it from the material rack 2 and lifts it out of the pit. After the operator leaves the pit body through the ladder 3, move the top cover 11 to the top of the pit body 1 to close the entire pit body 1.

[0032] Through the above equipment, the temperature control and power regulation device can automatically adjust the temperature in the pit so that the actual temperature in the pit is maintained at the set temperature (under the temperature condition of 100°C), realizing uninterrupted baking of the titanium alloy electrode and saving electricity energy consumption.
