Abstract
The utility model provides a hot change converter tapping hole structure of ability accurate positioning, by tapping oral siphon brick layer, the molten steel passageway, the connecting plate that tapping oral siphon brick layer one end is connected, tapping hole brick cup layer, the furnace body flange of connecting on tapping hole brick cup layer, connect the annular steel sheet on one section stay tube of tapping hole collar extension, fire resistant infilling layer between tapping hole brick cup layer and the tapping oral siphon brick layer is formed, it is connected with two cardboards relatively on the neighbouring connecting plate of annular steel sheet, be equipped with the wedge groove on every cardboard, insert tangible form matched with wedge in the wedge groove, tapping side on the connecting plate of neighbouring annular steel sheet is equipped with two at least locating pins, be equipped with asbestos washer between connecting plate and annular steel sheet. The utility model discloses an enable the tapping hole and fix a position fast, firm in connection, the clearance sealing performance between panel and the connecting plate is good, can not make the tapping hole structure lead to the fact damage, low in labor strength when just changing.
Description
Technical field
The utility model relates to a kind of steel-making tap hole, specifically belongs to the pinpoint hot replacing steel outlet structure of converter of a kind of energy.
Background technology
All kinds of converter (especially mammoth conveter) conventional steel tapping hole replacement method is normally: in hot situation, first drilling machine is adopted to clean out old tap hole, new tap hole is put in bored furnace lining hole, the mode being welded to connect iron plate is adopted to fix external orifice of steel-tapping hole panel, again converter is shaken to stove, finally fill with from tap hole internal orifice and spray into fire-resistant stopping composition among new steel-tapping hole tube brick with the gap of furnace lining brick cup, make it to sinter.
When fixing new tap hole, because tap hole is heavier, the method that external orifice of steel-tapping hole hand-stuff is sintered to fix can not meet tap hole firmly and the requirement of accurate positioning, easily cause tap hole fixed effect poor, even produce and come off or be shifted, and also increase labour intensity, length consuming time, namely generally need about 30 minutes.Also the mode adopting and to be welded on by external orifice of steel-tapping hole panel on tap hole root plate is had, although tap hole can be fixed by preferably, but the gap between panel and web plate can not tight closure, easily cause and Lou expect, therefore refractory mortar leak stopping must be replenished in gap, consuming timely like this need 15-20 minute, and each steel tapping hole replacement is complete, all can remain overlap and remaining connection iron plate on tap hole web plate.When after a few stove of use, the panel of disassembling furnace machine tool process tap hole need be used, from and the damage of steel-tapping hole tube brick collar extension can be caused, affect the work-ing life of tap hole, steel stream time serious, also can be made to disperse, cause burning out tap hole root board device and cause the accident.
Utility model content
The deficiency that the utility model exists for prior art, a kind of tap hole energy quick position is provided, be connected firmly, the clearance seal performance between panel and web plate is good, and tapping mouth structure can not be made to cause the pinpoint hot replacing steel outlet structure of converter of the energy of damage.
Realize the technical measures of above-mentioned purpose:
The pinpoint hot replacing steel outlet structure of converter of a kind of energy, by steel-tapping hole tube brick layer, the molten steel channel formed by steel-tapping hole tube brick layer, the web plate that steel-tapping hole tube brick layer one end connects, the tap hole brick cup layer of steel-tapping hole tube brick layer overcoat dress, the body of heater flange that tap hole brick cup layer is connected with one end with the web plate in steel-tapping hole tube brick layer, be connected to the doughnut-shaped steel plate on external orifice of steel-tapping hole one section of supporting tube, fire resistant infilling layer between tap hole brick cup layer and steel-tapping hole tube brick layer forms, it is: on the web plate that doughnut-shaped steel plate is contiguous, be relatively connected with two clamps, each clamp is provided with webge slot, the wedge that tangible shape matches is inserted in webge slot, tapping side on the web plate of adjacent rings steel plate is provided with at least two steady braces, asbestos washer is provided with between web plate and doughnut-shaped steel plate.
Feature of the present utility model: tap hole energy quick position, is connected firmly, the clearance seal performance between panel and web plate is good, and tapping mouth structure can not be made to cause damage, and when changing, labour intensity is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the right TV structure schematic diagram of Fig. 1;
In figure: 1-steel-tapping hole tube brick layer, 2-molten steel channel, 3-web plate, 4-tap hole brick cup layer, 5-body of heater flange, 6-doughnut-shaped steel plate, 7-fire resistant infilling layer, 8-clamp, 9-webge slot, 10-wedge, 11-steady brace, 12-asbestos washer.
Embodiment
Be described further below in conjunction with accompanying drawing:
The pinpoint hot replacing steel outlet structure of converter of a kind of energy, by steel-tapping hole tube brick layer 1, the molten steel channel 2 formed by steel-tapping hole tube brick layer 1, the web plate 3 that steel-tapping hole tube brick layer 1 one end connects, the tap hole brick cup layer 4 of the outer suit of steel-tapping hole tube brick layer 1, the body of heater flange 5 that tap hole brick cup layer 4 is connected with one end with the web plate 3 in steel-tapping hole tube brick layer 1, be connected to the doughnut-shaped steel plate 6 on external orifice of steel-tapping hole one section of supporting tube, fire resistant infilling layer 7 between tap hole brick cup layer 4 and steel-tapping hole tube brick layer 1 forms, it adopts welding or bolt relatively to connect two clamps 8 on the web plate 3 that doughnut-shaped steel plate 6 is contiguous, each clamp 8 is processed with webge slot 9, the wedge 10 that tangible shape matches is inserted in webge slot 9, tapping side on the web plate 3 of adjacent rings steel plate 6 is provided with three or four steady braces 11, asbestos washer 12 is housed between web plate 3 and doughnut-shaped steel plate 6.
During replacing, first lay tap hole to direction in stove along propelling movement along furnace lining hole, and guarantee that the doughnut-shaped steel plate 6 of tap hole end rests on steady brace 11 completely, doughnut-shaped steel plate 6 and asbestos washer 12 is compressed after tap hole places, wedge 10 is wedged on clamp 8 again and be processed with webge slot 9 li, thus tap hole is fixed, fixing complete employing stopping composition is by stifled for the gap between doughnut-shaped steel plate 6 and web plate 3 good.
After tilting converter to stove, spray into fire-resistant stopping composition from the filling of tap hole internal orifice and form fire resistant infilling layer 7 between steel-tapping hole tube brick layer 1 and the gap of tap hole brick cup layer 4, and sinter.Under the dual function that asbestos washer 12 and fire resistant infilling layer 7 seal, the fire-resistant stopping composition poured into can not spill, and ensure that material spray effect.
This embodiment is only the best and exemplifies, the restricted enforcement not to technical solutions of the utility model.
