Alignment mechanism 47 may be used to align pull eye bar 42 or the oxygen delivery tube, and the present application is described with respect to alignment mechanism 47 being used to align pull eye bar 42. When the pulling eye trolley 41 feeds the pulling eye bar 42 into the furnace eye, and the pulling eye bar deforms at high temperature, the straightening mechanism 47 can be used for straightening the pulling eye bar 42, so that the pulling eye bar 42 can be ensured to perform the pulling eye operation stably.

Specifically, the alignment mechanism 47 may have two alignment portions that are rotationally aligned to form an alignment space when the pull eye bar is required to align the pull eye bar so that the pull eye bar 42 passes through the alignment space of the alignment mechanism 47, and the alignment mechanism 47 may align the pull eye bar 42 during the reciprocating movement of the pull eye bar. When the pulling operation is completed, the two alignment portions of the alignment mechanism 47 are reversely rotated to open the alignment space, so that the pull eye bar is removed from the alignment mechanism 47, the time for removing the pull eye bar 42 from the alignment mechanism 47 is reduced, and the working efficiency of the tapping apparatus 100 is improved.

In the process of pulling the hole, the pull eye bar 42 is melted at high temperature and consumed and shortened, at this time, the clamping mechanism 43 releases the pull eye bar 42, the feeding mechanism 44 carries the pull eye bar 42, and the length of the pull eye bar 42 is compensated enough to enable the hole pulling assembly 40 to continue to work, so that the frequency of replacing the pull eye bar 42 is reduced, the consumption speed of materials is further reduced, and the working cost of the tapping device 100 is reduced. After the pulling operation is completed, the pulling eye carriage 41 is retracted to the tail of the pulling eye rail 45 away from the furnace eye.

When oxygen blowing operation is performed, the pull-eye trolley 41 is connected with the oxygen conveying pipe, and the clamping mechanism 43 on the pull-eye trolley 41 clamps the oxygen conveying pipe, after the pull-eye trolley 41 walks to the end part of the walking track 10 close to the furnace hole, the pull-eye trolley 41 sends the oxygen conveying pipe into the furnace hole to perform oxygen blowing operation, it can be stated that during oxygen blowing operation, the clamping mechanism 43 can loosen the oxygen conveying pipe, and the feeding mechanism 44 continuously conveys the oxygen conveying pipe to ensure that the pull-eye assembly 40 completes oxygen blowing operation. The pulling hole assembly 40 completes two operations of pulling holes and blowing oxygen, the whole process is completed by workers in a central control room through controlling the handles of the operation tables, a large number of workers are prevented from working at high temperature near the furnace holes, the safety and the reliability of the tapping equipment 100 of the ferroalloy submerged arc furnace are further improved, the labor cost can be reduced, and the labor intensity of the workers is reduced.
