Embodiment Construction
[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0019] figure 1 Schematically shows the structure of a preferred embodiment of the present invention, as shown in the figure, this preferred embodiment includes a control device 1, a telescopic arm device 2, a vacuum device 3, a slag suction device 4, a slag iron detection device 5, Switch off device 6. in addition, figure 1 In the figure, the molten iron tank 7 and the liquid level 71 of the molten iron therein are also shown, so as to clearly describe the application of this preferred embodiment.
[0020] In this preferred embodiment, the slag suction device 4 is used to extend downwards below the liquid surface 71 of the molten iron, of course it can also be close to the liquid surface 71 at a short distance, so that the slag suction chamber 41 can efficiently absorb the high temperature on the molten iron. Sulfur residue is the...

A telescopic boom type slag sucking machine comprises a slag sucker, a vacuumizing device, a slag iron detector, a telescopic boom device, a control device and a turn-off device. The slag sucker comprises a slag sucking cavity, the slag sucking cavity comprises a first port and a second port which are communicated with the external, and the first port of the slag sucking cavity is positioned on the lower surface of the slag sucker; an extract opening of the vacuumizing device is connected with the second port of the slag sucking cavity to vacuumize the slag sucking cavity; the slag iron detector is used for identifying slag iron after slag is sucked into the slag sucking cavity, and transmits an identification signal when molten iron is detected; the telescopic boom device is used for driving the slag sucker to move up and down; the control device is connected with the slag iron detector and is used for transmitting a driving signal after the identification signal is received; and the turn-off device is connected with the control device, is positioned in the slag sucker, corresponds to a slag iron combining surface and is used for instantly separating the slag iron after the driving signal is received. The telescopic boom type slag sucking machine has the advantages of capabilities of reducing iron loss and improving slag-off efficiency, convenience in operation, long service life and low cost.
Description
technical field [0001] The invention relates to a slag suction machine used in the slag removal process in the field of iron and steel metallurgy, in particular to a retractable telescopic arm type slag suction machine. Background technique [0002] Hot metal pretreatment is an important means to improve the quality of molten steel, expand the variety and improve the operation of converter steelmaking. It has become the main part of the optimization process of iron and steel metallurgical enterprises. Commonly used by enterprises. Clean, thorough, fast and effective removal of high-sulfur molten iron slag is the key to stabilizing the final effect of desulfurization, and it also directly affects the tapping at the end of the converter. [0003] Desulfurization and slag removal are two independent and closely related molten iron pretreatment processes. The desulfurization process determines the sulfur level of the molten iron at the end of the treatment, while slag removal i...
