Abstract

The utility model discloses a safety protection device for preventing drop of an oxygen lance during a blowing process. The device comprises an oxygen lance lifting orbit, wherein two sides of the oxygen lance lifting orbit are respectively provided with a movable choke block; a driving device is used for controlling the choke blocks to extend into or retract out of an effective region, through which an oxygen lance lifting trolley passes, on the oxygen lance lifting orbit. In the device disclosed by the utility model, when the oxygen lance is in normal blowing, the choke blocks mounted on the orbit of the oxygen lifting trolley move to the inside of the orbit of the oxygen lifting trolley to mechanically stop moving of the oxygen lifting trolley so as to prevent the drop of the oxygen lance; during operation of a sputtering slag protecting furnace, the chock blocks are shrank outside the orbit of the oxygen lifting trolley so as to ensure that the oxygen lance can successfully fall to a lance position of the sputtering slag protecting furnace, thus safer and more reliable operation is realized.

Description

The safety guard that anti-block rifle falls in converting process
Technical field
The utility model relates to the safety guard that a kind of anti-block rifle falls in converting process.
Background technology
In converter production process, along with the continuous application of slag splashing technique, the slag blanket that spatters that spatters slag formation has reduced refractory wear speed, reduce gunning material consumption, alleviate labor strength simultaneously, improve furnace lining work-ing life, improve converter operating rate, reduce production costs.And in order to realize slag splashing technique, the oxygen lance position while requiring oxygen lance position lower than normal blowing.During i.e. normal blowing, oxygen lance position is positioned at molten steel face top, and when slag splashing operates, oxygen lance position is positioned at below Normal Steel liquid level.In existing oxygen lance position operating process, there is following defect: when Converter Oxigen Blowing is made steel, exist due to mechanical fault or electrical accident cause that oxygen rifle rifle head is strayed into molten bath may.If oxygen rifle rifle head is strayed into oxygen rifle molten bath, may cause oxygen rifle oxygen hole plug, can not open oxygen blowing; More severe patient oxygen rifle rifle head melts, leaks, and sets off an explosion, and causes major industrial accident.
Utility model content
For the problems referred to above, the safety guard that provides a kind of anti-block rifle to fall in converting process is provided the purpose of this utility model.
For achieving the above object; the safety guard that a kind of anti-block rifle described in the utility model falls in converting process; comprise oxygen lance lifting orbit; an active block stop is installed in both sides on described oxygen lance lifting orbit, described block by a drive unit control stretch into or the oxygen lance lifting orbit that contracts on the effective area passed through for oxygen lance lifting bogie.
Preferably, described block and drive unit are structure as a whole, and described drive unit is retractor device, and the expansion link of this retractor device is described block.
Preferably, described drive unit adopts motion electronic, pneumatic or hydraulic way driving expansion link.
The beneficial effects of the utility model are:
The utility model the utility model oxygen rifle with anti-falling safe protection device in converting process be by mechanical locking guarantee oxygen rifle when blowing rifle position not under molten steel face, be not by electric control system guarantee oxygen rifle in converting process rifle position not below molten steel face.And existing oxygen gun system is calculated oxygen lance position by calculating oxygen lance lifting bogie transmission system reel rotating cycle, but when wire cable rupture, electrical accident or other reasons cause that oxygen rifle falls, unavoidably exist oxygen rifle rifle head to fall in converter molten pool dangerous.And the utility model is when oxygen rifle normally blows, the block being arranged on oxygen lance lifting bogie orbit moves in oxygen lance lifting bogie orbit, the motion of mechanical tissue oxygen lance lifting bogie, and anti-block rifle falls; When slag splashing operates, block is contracted to outside oxygen lance lifting bogie orbit, guarantees that oxygen rifle drops to slag splashing rifle position smoothly.Compare safety and reliability with existing skill.
2, the utility model drives block to move by drive unit, and reaction is quick.Block motion can adopt the type of drive such as electric transmission, pneumatic drive or hydrostatic transmission.The reaction of above type of drive fast, is compared with traditional manual mode, reaction sooner, more reliable.
3, the utility model is transmitted with the operation of oxygen rifle and is formed synchronized relation by signal.By drive unit signal, transmit, can synchronize with existing oxygen rifle operating system,, when oxygen rifle starts to blow, block moves in oxygen lance lifting bogie orbit automatically, but during slag splashing, block contracts automatically.Simple to operate.
Accompanying drawing explanation
Fig. 1 is the structure diagram of safety guard described in the utility model embodiment.
Embodiment
Below in conjunction with Figure of description, the utility model is further described.
Be illustrated in figure 1 the safety guard that a kind of anti-block rifle falls in converting process; it is mainly the motion of having accomplished can stop oxygen lance lifting bogie in converting process that this safety guard can reach that protection oxygen rifle falls in converting process, and then has reached the object that anti-block rifle falls.Therefore; in order to realize this effect; described safety guard comprises oxygen lance lifting orbit 3; an active block stop 1 is installed in both sides on described oxygen lance lifting orbit, described block by a drive unit 2, stretch into or the oxygen lance lifting orbit that contracts on the effective area passed through for oxygen lance lifting bogie 4.
Further explain, described block and drive unit are structure as a whole, and described drive unit is retractor device, and the expansion link of this retractor device is described block.In practical implementation, described drive unit adopts motion electronic, pneumatic or hydraulic way driving expansion link.Need in addition explanation, described block and drive unit can not be also integrative-structures, and block is block, be fixed on oxygen rifle trolley travelling track, and drive unit or drive unit, the drive end of this drive unit connects block.So separately the object of design, is convenient to more shift block or drive unit, very convenient.
Further explain, the utility model, to the practicable automatization control of drive unit, is synchronizeed and is carried out in converting process and slag splashing process with oxygen rifle, in converting process, drive unit promotes block automatically, in slag splashing process, and drive unit the automatic recovery block.
Working process of the present utility model is, when oxygen rifle normally blows, the block being arranged on oxygen lance lifting bogie orbit moves in oxygen lance lifting bogie orbit, the motion of mechanical tissue oxygen lance lifting bogie, and anti-block rifle falls; When slag splashing operates, block is contracted to outside oxygen lance lifting bogie orbit, guarantees that oxygen rifle drops to slag splashing rifle position, safety and reliability smoothly.
Above; it is only preferred embodiment of the present utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim was defined.
