Abstract
Description
Technical Field
[0001] This utility model relates to the field of electroslag remelting furnace technology, and more specifically, to an electroslag remelting furnace that is easy to clean. Background Technology
[0002] Electroslag remelting furnaces, as key equipment in the metallurgical industry, utilize the heat generated by current passing through high-resistance molten slag to remelt metals. Their working principle is as follows: the lower end of a consumable electrode is inserted into the slag pool. Current flowing through the molten slag generates Joule heat, gradually melting the electrode tip. The resulting molten droplets penetrate the slag layer and enter the molten metal pool. During this process, the droplets undergo a strong metallurgical reaction with the molten slag, effectively removing non-metallic inclusions from the metal and achieving metal refining. Finally, the metal solidifies into ingots or castings in a water-cooled copper crucible (crystallizer). This equipment is widely used in the steel and metallurgical industries, and can refine various alloy structural steels, heat-resistant steels, bearing steels, etc., using different slag materials. It can also directly produce high-quality cast steel parts such as large-diameter steel ingots and thick slabs through crystallizers of different shapes.
[0003] After the electroslag remelting process is completed, a large amount of electroslag and other impurities remain on the furnace lining. If these residues are not cleaned in time, they will not only affect the purity and quality of the metal in subsequent remelting processes, but may also lead to furnace lining corrosion and shorten the service life of the electroslag remelting furnace.
[0004] Currently, the cleaning of electroslag remelting furnace linings typically begins with manual or simple mechanical tools for preliminary cleaning to remove most of the residue. However, after preliminary cleaning, some stubborn fine particles, metal oxides, and chemical residues remain on the lining surface. These substances are difficult to remove completely mechanically and can adversely affect subsequent smelting processes. Water rinsing, utilizing the impact and dissolving properties of water flow, effectively removes these residues, ensuring the cleanliness of the furnace lining. Therefore, water rinsing becomes a crucial step in furnace lining cleaning after the preliminary cleaning.
[0005] Current methods for flushing furnace linings primarily involve operators manually holding water guns and entering the furnace to perform the flushing. This method has significant drawbacks. Firstly, manually holding a water gun makes it difficult to precisely control the height, angle, and pressure of the flushing, resulting in some areas of the lining being insufficiently flushed while others may waste water due to excessive flow, making it difficult to guarantee both flushing effectiveness and efficiency. Secondly, operators still face harsh environments such as high temperatures, humidity, and confined spaces when working inside the furnace, posing significant safety hazards. Furthermore, prolonged operation can easily lead to operator fatigue, affecting flushing quality. In addition, manual flushing lacks automated control, making it impossible to flexibly adjust the flushing process according to the actual conditions of the furnace lining, and failing to adapt to the cleaning needs of different operating conditions, thus limiting the overall efficiency and quality improvement of the cleaning work.

[0024] Example 1
[0025] The following is in conjunction with the appendix Figure 1-2 The present invention will be further described as follows:
[0026] This utility model provides an easy-to-clean electroslag remelting furnace 10. Please refer to [link / reference]. Figure 1-2 The easy-to-clean electroslag remelting furnace 10 includes an electroslag remelting furnace body 100, a movable support frame 200, a lifting mechanism 300, a connecting assembly 400, a motor 500, a remote control (not shown), an electric high-pressure water gun 600, and a water tank 700.
[0027] The connecting assembly 400 includes a connecting plate 410, a connecting rod 420, and a support platform 430.
[0028] In this embodiment, the movable support frame 200 is disposed on the outside of the electroslag remelting furnace 10 which is easy to clean, the lifting mechanism 300 is disposed on the movable support, one end of the connecting plate 410 is connected to the lifting mechanism 300, and the other end extends toward the furnace opening of the electroslag remelting furnace body 100.
[0029] The structure of the mobile support frame 200 can adopt existing technologies that enable the mobile support function, including but not limited to using a mobile platform with universal brake wheels to mount the support frame.
[0030] The structure of the lifting mechanism 300 can adopt existing technologies that can realize the lifting function, including but not limited to scissor lifts.
[0031] One end of the connecting rod 420 is rotatably connected to the connecting plate 410, and the other end is connected to the support platform 430, so that the support platform 430 can be close to or away from the furnace bottom of the electroslag remelting furnace body 100. In this embodiment, the motor 500 is connected to the connecting plate 410, the axis of the connecting rod 420 is parallel to the axis of the electroslag remelting furnace body 100, and the rotating shaft of the motor 500 passes through the connecting plate 410 and is coaxially connected to the connecting rod 420.
[0032] In this embodiment, the high-pressure water gun and water tank 700 are detachably connected to the support platform 430, and the detachment method includes, but is not limited to, fixing with bolts. The water spray direction of the electric high-pressure water gun 600 is perpendicular to the axis of the electroslag remelting furnace body 100.
[0033] In this embodiment, the electric high-pressure water gun 600 is equipped with an electrically connected circuit switch (not shown) and a signal receiver (not shown), and the remote control is equipped with a signal transmitter (not shown), with the signal receiver and the signal transmitter being electrically connected.
[0034] Specifically, the signal transmitter can adopt a commonly used structure in existing technology, mainly including a microcontroller, an encoding chip, and an RF transmission module. When the power button on the remote control is pressed, the microcontroller encodes the control signal through the encoding chip, and then transmits the encoded signal to the RF transmission module, which then transmits the signal in the form of radio waves.
[0035] The signal receiver can use a commonly used structure in existing technology, mainly including an RF receiving module, a decoding chip, and a microcontroller. After receiving the radio signal transmitted by the remote control, the RF receiving module converts it into an electrical signal and transmits it to the decoding chip. The decoding chip decodes the signal, restores the original control signal, and then transmits it to the microcontroller.
[0036] The microcontroller controls the on / off state of the circuit switch based on the received control signals. The circuit switch can use a commonly used structure in existing technology, typically consisting of components such as relays or power transistors. When an on signal is received, the microcontroller outputs a high-level or low-level signal, causing the relay to engage or the power transistor to conduct, thereby connecting the power circuit of the electric high-pressure water gun 600, causing the motor 500 to run and starting the water gun. When an off signal is received, the microcontroller outputs the opposite signal, causing the relay to disengage or the power transistor to turn off, cutting off the power and stopping the water gun from operating.
[0037] The easy-to-clean electroslag remelting furnace 10 provided in this embodiment operates as follows: When the furnace lining needs cleaning, the lifting mechanism 300 is activated to move the support platform 430 above the furnace opening. At this time, the movable support frame 200 is moved to a suitable position relative to the electroslag remelting furnace. The lifting mechanism 300 is then activated again to lower the support platform 430 from the furnace opening to the cleaning position inside the furnace. A water gun is controlled by a remote control to spray water. Turning on the motor 500 rotates the connecting rod 420 and the support platform 430, enabling rotational cleaning.
[0038] In summary, the easy-to-clean electroslag remelting furnace 10 provided in this embodiment can automatically rinse the furnace lining by using a remote-controlled high-pressure water gun after the electroslag remelting furnace has undergone preliminary cleaning, and can simultaneously realize the functions of rinsing height adjustment and rotation rinsing.
[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
