a central controller 304 connected to the pressure sensor 301, the distance sensor 302, and the liquid level detector 303;
the alarm 305 is provided in the console and connected to the central controller 304.
In the converter steelmaking process, after the torpedo car conveys the molten iron to a designated position, the torpedo tank 401 starts to be tipped, the molten iron is poured into the ladle 402, and the ladle pouring process is carried out. During the reladling process, the reladling safety device 300 can monitor the states of the torpedo tank 401 and the ladle 402 in real time through the pressure sensor 301, the distance sensor 302 and the liquid level detector 303.
In the specific implementation process, the pressure sensor 301 is disposed below the supporting trunnion of the ladle 402, and the pressure sensor 301 may be a metal pressure type sensor of type TY2004-rtn (g) -220T, and is configured to obtain the total weight of the molten iron in the ladle 402 and the ladle 402, and obtain the real-time molten iron weight through the difference between the total weight and the weight of the ladle 402.
Further, the device 300 includes two pressure sensors 301 respectively disposed below the two supporting trunnions of the ladle 402.
In a specific implementation process, the ladle 402 is transported by lifting two supporting trunnions on the ladle 402 by a transport trolley, one pressure sensor 301 is respectively arranged below the two supporting trunnions of the ladle 402, and the actual weight of the molten iron can be obtained by subtracting the sum of the weights obtained by the two pressure sensors 301 from the weight of the ladle 402.
The distance sensor 302 is movably disposed in a target installation area of the torpedo car 401 at a preset distance, and the distance sensor 302 may be an ultrasonic distance meter or an infrared laser distance meter. The preset distance may be a distance between the sensor 302 and the torpedo tank 401 in the horizontal direction, and the target installation area may be a wall or an installation area specially set for installing the distance sensor 302. The target mounting area may be in a direction opposite to the tap hole of the torpedo tank 401 when the torpedo tank 401 is tipped, or in a direction away from the tap hole of the torpedo tank 401 when the torpedo tank 401 is tipped. The distance sensor 302 is used for acquiring the distance between the tapping hole of the torpedo ladle 401 and the distance sensor 302 when the torpedo ladle is poured.
Further, the distance sensor 302 is a laser range finder.
Further, in order to enable the level detector 303 to more accurately measure the molten iron level in the ladle 402, the level detector 303 is set to have a height of 4m to 5m from the ground in the vertical direction, depending on the height of the ladle 402.
The central controller 304 is located in the control room, connected to the pressure sensor 301, the distance sensor 302, the liquid level detector 303, the torpedo tank 401 and the ladle 402, and is mainly used for controlling the operation state of the torpedo tank tapping system 400 according to the weight of molten iron, the distance between the torpedo tank 401 and the distance sensor 302 and the remaining space of the ladle 402, that is, controlling the system 400 to continue the ladle pouring process or controlling the system 400 to stop the ladle pouring process. When the weight of molten iron, the distance between the torpedo ladle 401 and the distance sensor 302 and the residual space of the ladle 402 do not meet preset conditions, the central controller 304 controls the alarm 305 to give an alarm while controlling the running state of the torpedo ladle tapping system 400.
And the alarm 305 is positioned on a console in the control room and is connected with the central controller 304, and the alarm can be formed by combining an alarm lamp and a buzzer and is mainly used for starting the alarm lamp and the buzzer to alarm after receiving an alarm control signal of the central controller 304.
Further, the apparatus 300 further comprises: a moving bracket 306, one end of which 306 is arranged on the target installation area and can move up and down in the direction vertical to the ground; the other end of the moving bracket 306 is fixed to the distance sensor 302.
The torpedo cars from different factories have different sizes and specifications. In a specific implementation process, the target installation area may be a wall perpendicular to the ground, when the distance sensor 302 measures the tap hole of the torpedo ladle 401, a slide rail or a slide perpendicular to the ground may be disposed on the target installation area, one end of the movable support 306 is installed on the slide rail or the slide rail of the target installation area, and can move up and down perpendicular to the ground, and the other end of the movable support 306 is fixed to the distance sensor 302. Just so can be convenient for distance-sensing ware 302 can carry out position adjustment according to torpedo ladle 401's size to measure torpedo ladle 401's taphole distance more accurately.
The distance between the distance sensor and the torpedo tank can be set according to actual needs, and in the embodiment of the specification, the distance between the distance sensor and the torpedo tank is 6-6.2 m.
For example, if the target installation area is in a direction opposite to the taphole of the torpedo tank 401 when the torpedo tank 401 tips, the preset distance between the sensor 302 and the taphole of the torpedo tank 401 is 6m to 6.2m, when the torpedo tank 401 taps, the distance between the taphole and the sensor 302 is gradually reduced, and when the measured distance exceeds the preset distance, it indicates that the tipping direction of the torpedo tank 401 is incorrect, or the distance between the torpedo tank and the ladle 402 is too far, and iron spilling may occur. Therefore, the central controller 304 will control the system 400 to stop running and control the alarm 305 to alarm.
If the target installation area is arranged in the direction departing from the taphole of the torpedo ladle 401 when the torpedo ladle 401 is tipped, the preset distance between the distance sensor 302 and the taphole of the torpedo ladle 401 is 6 m-6.2 m, when the torpedo ladle 401 is tapped, the distance between the taphole and the distance sensor 302 is gradually increased, and when the measured distance is smaller than the preset distance, the tipping direction of the torpedo ladle 401 is incorrect, or the distance between the torpedo ladle and the ladle 402 is too far, and iron spilling may occur. Therefore, the central controller 304 will control the system 400 to stop running and control the alarm 305 to alarm.
For convenience of explanation, the embodiment of the present specification mainly explains the present solution with a target installation area in a direction opposite to the taphole of the torpedo tank 401 when the torpedo tank 401 is tipped.

For example, if the preset molten iron weight threshold is 350t, the preset distance is 6m, and the preset remaining space threshold is 2L, the molten iron weight measured by the pressure sensor 301 is less than 350t, the distance between the sensor 302 and the iron outlet of the torpedo ladle 401 is less than 6m, and the remaining space of the ladle 402 is greater than 2L, the system 400 may operate normally. If one of the data items does not satisfy the preset value, the information analyzer 307 sends an alarm signal to the central controller 304.
Further, the apparatus 300 further comprises: the power source 309 and the power source 309 are connected with the pressure sensor 301, the distance sensor 302, the liquid level detector 303, the central controller 304 and the alarm 305 through cables to supply power to the device 300.
