Abstract
The utility model provides a steel outlet structure of converter convenient to be replaced, which includes the supporting tube (1) of a steel outlet, the outer end panel (2) of the supporting tube of the steel outlet and the root plate (3) of the steel outlet fixed on a converter body; two parallel snap rings (4) are welded on the root plate (3) of the steel outlet at the two sides of the root plate; an inclined wood wedge (5) is wedged between the snap rings (4) of the root plate of the steel outlet and the outer end panel of the supporting tube of the steel outlet, thereby fixing the supporting tube (1) of the steel outlet. The outer end panel (2) of the supporting tube of the steel outlet is a circular steel plate; and 1-2 asbestos washers (6) are arranged between the outer end panel (2) of the supporting tube of the steel outlet and the root plate (3) of the steel outlet. The steel outlet structure of converter convenient to be replaced realizes to quickly and firmly fix the replaced steel outlet of large converter, and guarantees the clearance between the panel of the steel outlet and the root plate, which not only meets the bearing demand of the tilting process of the converter during the replacing process, but also meets the demand that the filling materials during the ejecting process can fill in the gap between the steel outlet and the liner of the converter. Moreover, the steel outlet structure of converter convenient to be replaced can be sintered well and protect the cleanness of the root plate.
Description
Technical field
The utility model relates to a kind of converter tapping mouth structure of being convenient to change, and is applicable to converter steel tapping hole replacement in the converter less important work, directly applies to mammoth conveter steel-making less important work field.
Background technology
Mammoth conveter steel tapping hole replacement method is normally: adopt drilling machine to clear up old tap hole, new tap hole is put into, adopt the mode that is welded to connect iron plate to fix tap hole supporting tube collar extension panel, again converter is shaken to stove, mouth sprays into fire-resistant stopping composition in the slit of new tap hole and furnace lining in tap hole, makes it sintering.Mammoth conveter is changed tap hole, during fixing new tap hole, new tap hole is heavier, the method that adopts traditional external orifice of steel-tapping hole hand-stuff to be sintered to fix can not satisfy the requirement that fixedly secures tap hole, very easily cause the tap hole fixed difference, come off or be shifted, and increase labour intensity, length consuming time, need about 30 minutes, employing is welded on mode on the tap hole root plate with tap hole, tap hole is better fixing, but panel and root sheet separation can not be realized tightly, leak material easily, must between the gap, replenish the refractory mortar leak stopping, long palpus consuming time 15-20 minute, and descend tap hole to finish at every turn, all can be on the root plate residual overlap and the remaining iron plate that connects, use several stoves after, need to use the disassembling furnace machine tool to handle the panel of tap hole, cause the damage of tap hole pipe brick collar extension, influence the work-ing life of tap hole, when serious, steel stream is dispersed, burn out the root board device, cause the accident, during next steel tapping hole replacement, the space between panel and root plate increases, rosin joint in the time of can causing welding simultaneously, cause coming off of tap hole pipe brick, each clean for guaranteeing the root plate, the cleaning of must additionally arranging the time is welded the overlap of leaving over and is connected iron plate.
Summary of the invention
The purpose of this utility model is at the mammoth conveter tap hole; how change fast, firm a kind of converter tapping mouth structure of being convenient to change of fixed; guarantee gap between tap hole panel and root plate; replacing process converter inclining process load-bearing needs had both been satisfied; also satisfy the characteristics that material spray process stopping composition can fill up tap hole and furnace lining slit and sinter, protection root plate is clean.
The technical solution of the utility model: the converter tapping mouth structure of being convenient to change of the present utility model comprises tap hole supporting tube, tap hole supporting tube outer end panel, is fixed on the tap hole root plate on the body of heater, on tap hole root plate, be welded with two parallel snap rings and be positioned at root plate both sides, between inclined-plane timber wedge wedging tap hole root integrated circuit board ring and the tap hole supporting tube outer end panel, thus tap hole supporting tube 1 is fixing.
The described converter tapping mouth structure of being convenient to change, its tap hole supporting tube outer end panel is the annular steel plate, adds 1～2 asbestos washer between tap hole supporting tube outer end annular steel plate and tap hole root plate.
Advantage of the present utility model: the utility model has been cancelled the welding fixed form of new tap hole, adopt timber wedge expansion draw-in groove in inclined-plane to fix, shortened the activity duration, only needed to finish in 2-5 minute, and on tap hole root plate, can not stay any residue, need not handle, guarantee tight zero-clearance between tap hole panel and root plate, not need refractory mortar to fill.Alleviate operation labour intensity and activity duration, improved converter production efficiency.At tapping process, timber wedge be heated the burning nature come off, the tap hole panel comes off thereupon, to the no any damage influence of tap hole itself.
The utility model has been realized quick, firm the fixing of mammoth conveter replacing tap hole; and guaranteed gap between tap hole panel and root plate; replacing process converter inclining process load-bearing needs had both been satisfied; also having satisfied material spray process stopping composition can fill up tap hole and furnace lining slit and sinter, and protection root plate is clean.

Embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
Fig. 1, Fig. 2 are tap hole supporting tube and the outer face plate structure synoptic diagram before changing.The 1st, tap hole supporting tube, the 2nd, tap hole supporting tube outer end panel.Tap hole supporting tube outer end panel 2 is annular steel plates.
Fig. 3, Fig. 4 are overall structure synoptic diagram of the present utility model.
The 8th, body of heater, the 9th, fire door brick.On tap hole root plate 3, be welded with 4, two parallel snap rings 4 of two parallel snap rings and be positioned at tap hole root plate both sides, between inclined-plane timber wedge 5 wedging tap hole root integrated circuit board rings 4 and the tap hole supporting tube outer end panel 2, thus tap hole supporting tube 1 is fixing.Tap hole supporting tube outer end panel 2 is annular steel plates, adds 1～2 asbestos washer 6 between tap hole supporting tube outer end annular steel plate 2 and tap hole root plate 3.
Installation steps:
1) it is fixing with 2 welding of tap hole supporting tube outer end panel with tap hole supporting tube 1 that new tap hole is pressed accompanying drawing 1 mode, and supporting tube outer end panel 2 is annular steel plates;
