Description

Technical Field

[0001] The utility model relates to the field of steel smelting, in particular to a weighing result monitoring device for a vacuum consumable furnace. Background Art

[0002] In the field of special smelting, vacuum consumable furnaces are highly automated equipment. Vacuum consumable furnaces remelt steel ingots to further remove impurities and improve the purity of steel ingots. When the vacuum consumable furnace smelting enters a steady state, the automatic smelting control system will automatically start melting rate control. The melting rate is controlled based on the electrode weight. The electrode weight is measured by the weighing system and the information is transmitted to the control system. The system calculates the remaining electrode weight and then calculates the precise melting rate. The smelting process personnel need to use this melting rate to optimize the solidification rate of production. For some alloys, melting rate control is a good way to produce high-quality steel ingots. It can be seen that the accuracy of the weighing system is particularly important.

[0003] There is a "weighing error" fault in the smelting process of the vacuum consumable furnace. The on-site production environment is complex, and there are many factors that will affect the accuracy of the weighing value, such as whether there is abnormal vibration on site that causes the sensor to move, whether the fixing bolts of the sensor are loose, whether there is signal interference in the sensor signal transmission, whether the vacuum is abnormal and interferes with the normal operation of the vacuum compensator, whether the weighing sensor itself is faulty, etc. Once the "weighing error" alarm occurs, it will have a great impact on the quality of the finished steel. The most difficult factor to troubleshoot and prevent among the weighing error influencing factors is the failure of the weighing sensor itself. The weighing sensor is a high-precision instrument. When there is a problem with the weighing sensor itself, it is impossible to determine whether it is faulty by checking whether the appearance is damaged, and the operating status of the sensor cannot be monitored.

[0007] Furthermore, it also includes a signal isolator, and the weighing sensor and the vacuum compensator are both connected to the monitoring mechanism through the signal isolator.

[0008] Furthermore, the output voltage of the signal isolator does not exceed 10V.

[0018] like Figure 1 As shown, according to an embodiment of the utility model, a device for monitoring the weighing results of a vacuum consumable furnace is provided, comprising: a weighing sensor, the weighing sensor is used to detect the weight of the electrode of the vacuum consumable furnace; a monitoring mechanism, the weighing sensor is connected to the monitoring mechanism, and the monitoring mechanism can monitor the detection data of the weighing sensor; a compensation mechanism, the compensation mechanism can detect the air pressure of the environment where the electrode is located, the compensation mechanism is connected to the monitoring mechanism, and the monitoring mechanism can monitor the detection data of the compensation mechanism.

[0019] The compensation mechanism includes a vacuum compensator, which is connected to the monitoring mechanism. The vacuum compensator can detect the air pressure of the environment where the electrode is located, and transmit the monitored air pressure information to the monitoring mechanism. The measurement data of the weighing sensor is compensated according to the measured air pressure of the environment, thereby removing the influence of the air pressure on the detection results of the weighing sensor. The vacuum compensator can be a strain gauge sensor, such as the Super TJE strain gauge sensor produced by HONEYWELL.

[0020] The monitoring mechanism collects data from the load cell and the vacuum compensator, and stores the collected data in the monitoring mechanism. The user can analyze the status of the load cell based on the data in the monitoring mechanism. Usually, the monitoring mechanism can process the data into curves or other easily comparable forms, thereby facilitating the user to compare the data.

[0021] It also includes a signal isolator, through which the weighing sensor and the vacuum compensator are connected to the monitoring mechanism. The output voltage of the signal isolator does not exceed 10V.

[0022] The signal isolator converts the sensor's millivolt signal into a 0-10V output signal, and integrates it into the monitoring mechanism to achieve real-time monitoring of the weighing sensor and vacuum compensator. Secondly, by comparing a group of curves, the overall usage of the weighing sensor and vacuum compensator can be judged. This can ensure the accuracy of the output signal of the weighing sensor used online, accurately grasp the cracking trend of the weighing system, predict maintenance, replace deteriorated sensors in advance, and eliminate the impact of weighing errors on the quality of smelting steel ingots.

[0023] It also includes a sensor junction box, through which the weighing sensor and the vacuum compensator are connected with the signal isolator.

[0024] The sensor junction box acts as a wiring relay, allowing subsequent structures to be connected to the load cell and vacuum compensator.

[0025] It also includes a digital converter, which is connected to the sensor junction box and the monitoring mechanism. The sensor junction box can simultaneously transmit the weight information of the electrode detected by the weighing sensor and the vacuum compensator to the digital converter, and the digital converter can transmit the processed weight information of the electrode to the monitoring mechanism.

[0026] The digital converter can convert the output signals of the weighing sensor and the vacuum compensator into digital display, so that the user can directly obtain the monitoring data of the weighing sensor and the vacuum compensator.

[0027] The monitoring mechanism comprises a display and a control module. The control module can receive the weight information of the electrode sent by the weighing sensor and the vacuum compensator and display it on the display after processing.

[0028] The monitoring mechanism usually requires a display and a control module, and the user monitors the detection data through the display.

[0029] From the above description, it can be seen that the above-mentioned embodiments of the utility model achieve the following technical effects: by monitoring the usage status of the weighing sensor and forming traceable historical data, by analyzing the historical data, the device status of the sensor is grasped, and the failure point of the weighing sensor is predicted in advance.

[0030] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
