Embodiment
A kind of device of controlling molten steel jar headroom comprises fixed support, scale, sees Fig. 1, fixed support is made up of adapter sleeve 1, nut, bolt 3, adapter sleeve 1 is L shaped, and the steel plate of adapter sleeve 1 bottom and molten steel jar tank skin 8 shells is fixed, and adapter sleeve 1 sidepiece is provided with nut bore 2.See Fig. 2, scale comprises chi head 4, outer chi pawl 5, interior chi pawl 6, chi foot 7, and outer chi pawl 5 screws in nut bore 2 by bolt 3 and fixes between L shaped adapter sleeve 1 and molten steel jar tank skin 8.Chi head 4 contacts along upper surface with molten steel jar jar, and interior chi pawl 6 is positioned at molten steel jar inner pot below the plane with chi foot 7; Chi head 4 and outer chi pawl 5 vertical settings, interior chi pawl 6 is a plurality of with chi foot 7, and interior chi pawl 6 be arranged in parallel with outer chi pawl 5, and chi pawl is connected with chi head 4 in first; Interior chi pawl 6 is the right angle with chi 7 alternate layouts of foot and junction.Outer chi pawl, chi head, interior chi pawl and chi can be formed by a steel tube bending completely, or adopt many steel pipes to be welded.
When using this device to carry out headroom control, need insert the outer chi pawl 5 of scale in the L shaped long end of adapter sleeves 1 in advance, and interior chi pawl 6 need be placed on molten steel jar inner and upper, treat that chi head 4 touches the molten steel jar along upper surface, being about to bolt 3 screws in the adapter sleeve 1, outer chi pawl 5 is fixed between adapter sleeve 1 and the tank skin, thereby nonadjustable signal can be used for the control of molten steel jar headroom subsequently at tapping process.This device can accurately be controlled the headroom of molten steel jar, and error range is in ± 50mm scope.
Example: service condition is 180 tons of pneumatic steelmakings, and the headroom range of control of smelting steel grade requirement molten steel jar is 300mm～700mm scope, is that a unit controls with 100mm.
Wherein adapter sleeve 1 short end welds with molten steel jar tank skin 8 shell steel plates, and adapter sleeve 1 material is that internal diameter is the steel pipe of 25mm.Chi head 4 length of scale are 450mm, and outer chi pawl 5 length are 350mm, and chi pawl 6 length are 300mm in first that is connected with chi head 4, and all the other 4 interior chi pawl length are 100mm, and 5 chi foot 7 length are 100mm.
The making of scale is to adopt the steel pipe that external diameter is 20mm, length should be greater than 2000mm, set the size place at each, be heated to the flexible degree of steel pipe, be bent into scale shown in the 2 scale synoptic diagram with reference to the accompanying drawings then, after completing, the 1st the chi foot 7 brush red paints that will be connected with chi head 4, the 3rd chi foot 7 brush yellowly paint, the 5th the sufficient look paint of greenwashing of chi.
After the molten steel jar is normally reorganized and outfit end, the outer chi pawl 5 of scale is inserted the long end of adapter sleeve 1,6 chi foots 7 of interior chi pawl that should guarantee scale this moment are in the molten steel jar, when treating that chi head 4 touches the upper surface on molten steel jar jar edge, bolt 3 is screwed in the nut 2, the outer chi pawl 5 of scale is fixing, promptly finish installation exercise.
In the converter tapping process, carry out the control of molten steel jar headroom according to the requirement of the required headroom of steel grade, when required headroom is 300mm, tapping process is observed and has been reached default headroom when molten steel touches the 1st chi foot (redness), when required headroom is 400mm, molten steel has reached default headroom when touching the 2nd chi foot (red next), when required headroom is 500mm, molten steel has reached default headroom when touching the 3rd chi foot (yellow), when required headroom is 600mm, molten steel has reached default headroom when touching the 4th chi foot 7 (yellow next), when required headroom was 700mm, molten steel had reached default headroom when touching the 5th chi foot 7 (greens).Reach when presetting headroom, should in time lift stove, carry out the pushing off the slag operation simultaneously.
