Therefore, it should not be understood as a limitation on the present invention.

[0033] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0034] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0035] The converter tilting device is one of the most critical equipment in the steelmaking system. It consists of a drive motor, a primary reducer, a secondary reducer, a torsion bar balancing device, and a lubrication device. During operation, four motors drive four primary reducers respectively, and one secondary reducer at the same time. The output gear shafts of the four primary reducers simultaneously mesh with the large gear of the secondary reducer. The large gear transmits torque to the converter drive end trunnion through the tangential key, thereby driving the converter operation. Therefore, the reducer is an important equipment in the converter system. To ensure the normal operation of the reducer, the gears inside the reducer need to be lubricated with thin oil at all times to reduce gear wear. This is to ensure that the furnace body can continuously rotate 360 ​​degrees forward and reverse, and can accurately and smoothly stop at any angle position to meet the steelmaking process operations such as adding molten iron, charging, sampling, temperature measurement, tapping, slag discharge, and return.

[0036] In the prior art, during the lubrication process of the converter tilting device, there is a problem that the temperature of the lubricating oil is too low, which affects the operation of the converter tilting device and causes the converter tilting device to malfunction.

[0037] Please refer to Figure 1 This embodiment provides a lubricating oil heating device 100 for a converter tilting device, which can effectively improve the technical problems mentioned above, heat the lubricating oil, prevent the lubricating oil temperature from being too low and thus affecting the operation of the converter tilting device, avoid malfunction of the converter tilting device, and improve the working stability of the converter tilting device.

[0038] Please refer to Figure 1 The lubricating oil heating device 100 of the converter tilting device includes a heat accumulator 30, a steam drum assembly, a steam pipe 101 and a reducer 60. The heat accumulator 30 is used to be connected to the converter 10. One end of the steam pipe 101 is connected to the steam drum assembly, and the other end of the steam pipe 101 is connected to the heat accumulator 30. The steam pipe 101 is used to transport the high-pressure steam in the heat accumulator 30 to the steam drum assembly, so that the high-pressure steam heats the lubricating oil inside the steam drum assembly. The reducer 60 is connected to the steam drum assembly, and the steam drum assembly is used to transport the heated lubricating oil to the reducer 60, so that the heated lubricating oil lubricates the reducer 60.

[0039] Specifically, 320 gear oil is typically used to lubricate the reducer 60. Because the temperature of gear oil fluctuates seasonally, dropping in winter and rising in summer, low temperatures increase the viscosity of the gear oil, turning it semi-solid. This results in poor fluidity, reduced lubricity and wear resistance, and accelerated gear wear. This can easily lead to serious accidents caused by even minor transmission errors during the rotation of the converter 10, which is fully loaded with molten steel. Furthermore, low-temperature gear oil can cause moisture in the gear oil to solidify. This solidified water adheres to surfaces such as hydraulic valve components and the oil filter, potentially causing the hydraulic valve to seize and the filter to clog, rendering the hydraulic system inoperative. Low-temperature gear oil can also shrink and harden the rubber seals in the hydraulic system, reducing sealing performance and even causing seal failure. Low-temperature gear oil can also cause the gear oil itself to shrink, particularly within the enclosed cavity, causing a pressure drop or even negative pressure. In order to solve the above technical problems, the lubricating oil heating device 100 of the converter tilting device in this embodiment recovers the high-pressure steam of the converter 10 when in use, and the pressure and temperature of the high-pressure steam are adjusted in the heat accumulator 30 to ensure that the pressure and temperature of the steam are stable. Then the high-pressure steam enters the steam drum assembly through the steam pipe 101, and the high-pressure steam is used to heat the lubricating oil in the steam drum assembly, thereby increasing the temperature of the lubricating oil. The heated lubricating oil flows out of the steam drum assembly and flows into the reducer 60 for lubrication. The lubricating oil heating device 100 of the converter tilting device can prevent the lubricating oil temperature from being too low, thereby affecting the operation of the lower converter tilting device, avoiding failure of the converter tilting device, and improving the working stability of the converter tilting device.

[0040] Specifically, after the steam of the converter 10 is regulated by the heat accumulator 30, the saturated steam temperature reaches more than 200 degrees, and is guided into the steam drum assembly through the steam pipe 101, so as to achieve the purpose of steam heating the lubricating oil and save energy consumption.

[0041] In this embodiment, the steam drum assembly includes a steam drum oil inlet tank 40 and a steam drum oil outlet tank 50, which are connected to each other, and are connected to the steam drum oil inlet tank 40 and the steam drum oil outlet tank 50. The steam drum oil inlet tank 40 is connected to the steam pipe 101, and the steam drum oil outlet tank 50 and the steam drum oil inlet tank 40 are both connected to the reducer 60. The high-pressure steam in the steam pipe 101 enters the steam drum oil inlet tank 40 to heat the lubricating oil inside it. The heated lubricating oil flows to the steam drum oil outlet tank 50 and flows out from the steam drum oil outlet tank 50 to the reducer 60. The heated lubricating oil lubricates the reducer 60 and finally flows back into the steam drum oil inlet tank 40 after lubrication. In this embodiment, the steam drum assembly also includes an oil pipe 102, one end of which is connected to the steam drum oil inlet tank 40, and the other end of which is connected to the steam drum oil outlet tank 50. Specifically, the lubricating oil in the sub-steam drum oil inlet tank 40 is transported to the sub-steam drum oil outlet tank 50 through the oil pipe 102 .

[0042] In this embodiment, the steam drum oil inlet tank 40 and the steam drum oil outlet tank 50 are arranged at intervals, and the oil pipe 102 is arranged between the steam drum oil inlet tank 40 and the steam drum oil outlet tank 50, and the oil pipe 102 is arranged horizontally. The two ends of the oil pipe 102 are respectively connected to the side walls of the steam drum oil inlet tank 40 and the steam drum oil outlet tank 50. The lubricating oil in the steam drum oil inlet tank 40 can be dispersed in the oil pipe 102 and gathered in the steam drum oil outlet tank 50 after heating.

[0043] Specifically, there are multiple oil pipes 102, which are spaced apart in the vertical direction. In this embodiment, there are six oil pipes 102, which are arranged in parallel. In other embodiments, the number of oil pipes 102 may be increased or decreased, and this is not specifically limited here.

[0044] It should also be noted that multiple oil pipes 102 are packaged inside the steam drum so that the lubricating oil in the oil pipes 102 can be heated quickly. At the same time, a drain port 108 is provided at the bottom of the steam drum. The drain port 108 is used to discharge water generated during steam cooling to prevent the pipes from rusting and corroding.

[0045] Furthermore, the steam pipe 101 in this embodiment includes two branches, each of which has an inlet that is connected to the regenerator 30. The outlet of one branch is connected to the sub-steam drum oil inlet tank 40, while the outlet of the other branch is directly connected to the sub-steam drum. Therefore, it can be seen that the high-pressure steam in the regenerator 30 can not only heat the sub-steam drum oil inlet tank 40 through the steam pipe 101, but also heat the multiple oil pipes 102 through the steam pipe 101.

[0046] In this embodiment, a drain port 108 is also provided at the bottom of the steam drum oil inlet tank 40 for discharging water generated during steam cooling to prevent rust and corrosion of the pipeline.

[0047] It should be noted that the drain outlet 108 provided in the steam drum and the steam drum oil inlet tank 40 is controlled by a valve, so that the drain outlet 108 is periodically opened and closed.

[0048] More preferably, a drain port 108 is also provided at the bottom of the sub-steam drum oil inlet tank 40 .

[0049] The steam pipe 101 may also be directly connected to the oil pipe 102 to directly heat the lubricating oil inside the oil pipe 102 .

[0050] Furthermore, the lubricating oil heating device 100 of the converter tilting device also includes an oil inlet pipe 103 and an oil outlet pipe 104. One end of the oil inlet pipe 103 is connected to the steam drum oil outlet tank 50, and the other end of the oil inlet pipe 103 is connected to the top of the reducer 60. One end of the oil outlet pipe 104 is connected to the steam drum oil inlet tank 40, and the other end of the oil outlet pipe 104 is connected to the bottom of the side wall of the reducer 60.

[0051] Specifically, one end of the oil inlet pipe 103 is welded to the steam drum oil outlet tank 50, an oil inlet hole is opened on the top of the reducer 60, and the other end of the oil inlet pipe 103 is welded to the oil inlet hole. The connection between the oil inlet pipe 103 and the top of the reducer 60 can ensure that the heated lubricating oil is sprayed and covers the gears of the reducer 60.

[0052] Furthermore, the automatic heating device for lubricating oil of the converter tilting device further includes an oil outlet pipe 104 , one end of which is connected to the primary reducer 60 , and the other end of which is connected to the steam drum oil inlet tank 40 .

[0053] Specifically, an oil outlet hole is opened at the bottom of the side wall of the reducer 60, one end of the oil outlet pipe 104 is welded to the steam drum oil inlet tank 40, and the other end of the oil outlet pipe 104 is welded to the oil outlet hole. The oil outlet hole is arranged at the bottom of the side wall of the reducer 60 to prevent the bottom sediment of the reducer 60 from spraying onto the gears of the reducer 60, thereby avoiding accelerated gear wear.

[0054] In this embodiment, to automatically open and close steam pipe 101, a temperature controller 105 is installed on oil inlet pipe 103, and a temperature sensor 106 is installed on steam pipe 101. A normal oil temperature range is set on temperature controller 105 to ensure that the lubricating oil does not become semi-solid. Temperature sensor 106 is also installed on steam pipe 101 to automatically control the valve opening and closing, and a linkage function is implemented between temperature controller 105 and temperature sensor 106.

[0055] Specifically, heating state: when the temperature sensor 106 receives the temperature detected by the temperature controller 105 and the temperature is lower than the normal temperature value, the steam pipe 101 is automatically in the open state, and the oil pipe 102 in the steam drum is heated to meet the temperature requirements. When the temperature sensor 106 receives the temperature detected by the temperature controller 105 and the temperature is higher than the normal temperature range, the steam pipe 101 will automatically close and stop heating, thereby ensuring that the oil temperature is normal.

[0056] Furthermore, the automatic heating device for lubricating oil of the converter tilting device also includes an automatic oil replenishing component 70 and an oil level display 80. The automatic oil replenishing component 70 is connected to the steam drum oil inlet tank 40. The oil level display 80 is arranged on the reducer 60. The automatic oil replenishing component 70 is used to automatically replenish oil to the steam drum oil inlet tank 40 when the oil level display 80 detects that the amount of oil inside the reducer 60 is insufficient.

[0057] It can be understood that the oil level display 80 is used to display the oil level of the lubricating oil inside the reducer 60. Since the lubricating oil will evaporate during the heating process, the lubricating oil will become less. When the oil level display 80 detects that the oil level in the reducer 60 is insufficient, the automatic oil replenishing component 70 can automatically replenish oil into the steam drum inlet tank 40, avoiding the need to open the cover of the reducer 60 to refuel.

[0058] Furthermore, the lubricating oil heating device 100 of the converter tilting device also includes a thin oil pump 107, which is arranged in the oil outlet pipe 104. The thin oil pump 107 can ensure that a pressurized internal circulation is formed in the oil outlet pipe 104 and the oil inlet pipe 103, so that the lubricating oil is sprayed in a spray state and covers the gears of the reducer 60.

[0059] Furthermore, due to the unique characteristics of steelmaking converters, steam generation is intermittent and fluctuating, resulting in highly unstable steam pressure, temperature, and output. Consequently, when using steam to heat the lubricating oil, the oil temperature can overheat. Excessive oil temperature has the following consequences: High temperatures reduce the viscosity of the hydraulic oil, leading to excessively low viscosity, increased leakage in the hydraulic system, reduced efficiency, and even malfunction of the hydraulic system. High temperatures exacerbate the oxidation of the hydraulic oil, gradually generating substances such as ketones, acids, colloids, and asphaltenes, which contaminate the hydraulic oil and shorten its service life. When the hydraulic oil oxidizes to a certain degree, it becomes ineffective and unusable. High temperatures chemically decompose the lubricating film formed on the metal surfaces in the friction areas, destroying it. High temperatures often exacerbate corrosion of steel and other non-ferrous metals in the hydraulic oil, causing surface damage to components and the generation of corrosive products. High temperatures also promote the formation of bubbles, which disrupt the lubricating film, causing sintering and increased wear on the friction surfaces. They also accelerate oxidation and deterioration of the hydraulic oil, impacting the accuracy and sensitivity of hydraulic components and, in severe cases, failing to meet the requirements of the hydraulic system. High temperatures degrade the performance of rubber seals in hydraulic systems, causing them to swell and soften, accelerating rubber aging and even leading to seal failure. High temperatures also expand the volume of hydraulic oil, increasing the pressure within the chamber and creating a dangerous situation. Therefore, to ensure a stable steam flow, the converter tilting device lubricating oil heating device 100 also includes a pressure vessel 20, which is connected to both the converter 10 and the heat accumulator 30. The pressure vessel 20 recovers and stores the steam generated by the converter 10.

[0060] The embodiment of the present invention further provides a converter tilting device lubricating oil heating process, which utilizes the converter tilting device lubricating oil heating device 100 to achieve heating. The heating process includes:

[0061] S1: Controlling the heat accumulator 30 to regulate the pressure and temperature of the high-pressure steam generated by the converter 10. The regulated high-pressure steam enters the sub-steam drum oil inlet tank 40 through the steam pipe 101 to heat the lubricating oil in the sub-steam drum oil inlet tank 40;

[0062] Specifically, the pressure vessel 20 is controlled to recover and store the steam generated by the converter 10, and the heat accumulator 30 is controlled to regulate the pressure and temperature of the steam. When the temperature detected by the temperature controller 105 received by the temperature sensor 106 is lower than the normal temperature value, the steam pipe 101 is automatically opened, and the steam enters the steam drum oil inlet tank 40 through the steam pipe 101 and heats the lubricating oil.

[0063] S2: Control the heated lubricating oil to flow through the oil pipe 102 into the steam drum oil outlet tank 50;

[0064] S3: Control the lubricating oil in the oil outlet tank 50 of the sub-steam drum to enter the top of the reducer 60 through the oil inlet pipe 103 to lubricate the gears inside the reducer 60;

[0065] Specifically, the heated lubricating oil reaches the top of the reducer 60 through the oil inlet pipe 103 and is sprayed onto the gears of the reducer 60 to lubricate the gears;

[0066] S4: After lubrication is completed, the lubricating oil is controlled to return to the steam drum oil tank 40 through the oil outlet pipe 104;

[0067] S5: When the oil level indicator 80 detects that the oil level in the reducer 60 is insufficient, the automatic oil replenishing component 70 is controlled to automatically replenish oil to the sub-steam drum oil inlet tank 40.

[0068] The lubricating oil heating device 100 for a converter tilting device provided in this embodiment has at least the following advantages:

[0069] The converter tilting device lubricating oil heating device 100 can ensure that the lubricating oil sprayed on the gears of the reducer 60 in winter is not semi-solid, and ensure that the lubricating oil can meet normal use requirements.

[0070] The lubricating oil heating device 100 of the converter tilting device can utilize the steam generated by the converter 10 to heat the thin oil, thereby solving the problem of gear wear caused by low temperature in winter.

[0071] To sum up, an embodiment of the present invention provides a lubricating oil heating device 100 for a converter tilting device and a heating process. The lubricating oil heating device 100 for a converter tilting device includes a heat accumulator 30, a steam drum assembly, a steam pipe 101 and a reducer 60. The heat accumulator 30 is used to be connected to the converter 10, one end of the steam pipe 101 is connected to the steam drum assembly, and the other end of the steam pipe 101 is connected to the heat accumulator 30. The steam pipe 101 is used to transport the high-pressure steam in the heat accumulator 30 to the steam drum assembly, so that the high-pressure steam heats the lubricating oil inside the steam drum assembly. The reducer 60 is connected to the steam drum assembly, and the steam drum assembly is used to transport the heated lubricating oil to the reducer 60, so that the heated lubricating oil lubricates the reducer 60. When the converter tilting device lubricating oil heating device 100 is in use, it ensures the circulation of lubricating oil, and the heat accumulator 30 recovers the high-pressure steam of the converter 10. The high-pressure steam is pressure- and temperature-regulated in the heat accumulator 30 to ensure the stability of the steam pressure and temperature. Then the high-pressure steam enters the steam drum assembly through the steam pipe 101, and the high-pressure steam is used to heat the lubricating oil in the steam drum assembly, thereby increasing the temperature of the lubricating oil. The heated lubricating oil flows out of the steam drum assembly and flows into the reducer 60 for lubrication. The converter tilting device lubricating oil heating device 100 can prevent the lubricating oil temperature from being too low, thereby affecting the operation of the converter tilting device, avoiding malfunction of the converter tilting device, and improving the working stability of the converter tilting device.
