Embodiment 1
[0028] figure 1 It is a schematic structural diagram of a liquid level detection device in an embodiment of the present invention, such as figure 1 Shown:
[0029] The liquid level detection device is used for liquid level detection at the nose of the slagging furnace and the zinc pot, wherein the zinc pot 1 has an accommodating space, and liquid zinc is placed in the accommodating space; the furnace nose 3 It is arranged in the accommodating space, and the bottom end of the furnace nose 3 protrudes below the liquid level of the zinc liquid, and the furnace nose 3 and the bottom surface of the zinc pot 1 have a preset angle.
[0030] Specifically, the zinc pot 1 is a structure for accommodating molten zinc in the device, and the zinc pot 1 is mainly used to contain and heat the molten zinc so as to keep the molten zinc in a molten state. The bottom of the furnace nose 3 is inserted obliquely downward into the bottom of the zinc pot 1 and is not in contact with the bottom of th...
Embodiment 2
[0041] figure 2 It is a schematic flow chart of a method for controlling the liquid level of the slagging furnace nose and the zinc pot in the embodiment of the present invention, such as figure 2 As shown, the method for controlling the slagging furnace nose and the liquid level of the zinc pot includes:
[0042] Step 1: Obtain the steel coil information of the production line, and calculate the consumption of the first zinc ingot per unit time according to the steel coil information.
[0043] Specifically, when controlling the liquid level of the zinc pot, firstly, obtain the specification information of the strip steel in the current production line, the specification information includes width, speed, coating, etc., and then calculate the zinc ingot per unit time based on the strip steel information consumption.
[0044] Step 2: Judging whether it is the slag removal mode, if so, adjusting the consumption of the first zinc ingot to the consumption of the second zinc in...
Embodiment 3
[0059] The embodiment of the present invention also provides a slagging furnace nose and zinc pot liquid level control system, including the aforementioned liquid level detection device, and the slagging furnace nose and zinc pot liquid level control system also includes:
[0060] A controller, the controller is respectively connected with the first liquid level gauge 9, the second liquid level gauge 5, and the zinc ash pump 7. A zinc adding device 8, the zinc adding device 8 receives a zinc adding instruction from the controller, and adds zinc ingots into the zinc pot 1 .
[0061] Specifically, the zinc adding device 8 is a device for adding zinc ingots into the zinc pot 1, and the zinc adding device 8 receives a zinc adding command from the controller, and regularly feeds zinc ingots into the zinc pot. Further, the control device is respectively connected with the first liquid level gauge 9, the second liquid level gauge 5, the zinc ash pump 7, and the zinc adding device 8, ...
