Abstract
The invention belongs to metallurgical technology fields, more particularly to a kind of mineral hot furnace furnace lining brick fuel and brickwork joint encapsulation process method, it is embedded at least one layer of annular groove on the brick fuel, is filled with carbon materials in the annular groove, the carbon materials are fixed on by strap in the annular groove.The present invention advantage be：Cured using the carbon materials in brick fuel annular groove, adjacent brick fuel is closely joined together, and then block leaked under molten iron completely；Namely significantly extend the service life of mineral hot furnace furnace lining by thoroughly eliminating the gap between tiling brick fuel.
Description
Technical field
The invention belongs to metallurgical technology fields, and in particular to a kind of mineral hot furnace furnace lining brick fuel and brickwork joint encapsulation process method.
Background technology
The capacity of current mineral hot furnace is increasing, and the capacity of normal stove all reaches 20MVA, 30MVA, and large-scale has
100MVA.And furnace lining involves great expense, the furnace lining price of high capacity oven is up on ten million yuan.But existing furnace lining brick-building art
There is serious defects, especially build horizontal inferior furnace lining by laying bricks or stones, can be scrapped within the extremely short time, caused by loss be
It is very huge.
The main reason for being found in long-term production practices, causing furnace lining premature breakdown be existing brick-building art not
Graphite brick fuel can be made to one and do not have apertured complete body, what the splicing gap between brick fuel was constantly present.And this can not disappear
The gap removed is to cause the fatal reason that furnace lining damage too early or service life are not grown in addition to because of brick fuel sole mass factor.Brick fuel
Between splicing gap Producing reason have at 2 points：First, the live knotting compactness for building vertical seam when carbon brick by laying bricks or stones can not possibly camera charcoal processing
The compactness of brick is high like that, and cellular shrinkage hole is necessarily led in sintering process, so gap is caused to generate；Second, due to
The expansion buffer gap of 50-60mm, furnace lining material are stayed when furnace lining is built by laying bricks or stones between furnace shell inner wall and fire proof material of furnace lining（Including charcoal
Brick）The alternating variation expanded with heat and contract with cold is generated with lifting repeatedly for fire box temperature, even in this way, founding seam when constructing between brick fuel
Knotting quality is very good or is built by laying bricks or stones using the very high seamless spliced brick fuel of machining accuracy, also can be cold with heat expansion
The increase of the contracting number of alternations and generate, increase gap between brick fuel.In fact, the damage of most of furnace linings be all due to molten iron from
Leakage is gone down and is caused in this gap because the proportion of molten iron is heavy more compared with brick fuel, when leak the molten iron that down by
When forming liquid levels layer cumulative, just brick fuel being floated up, the damage so as to cause entire furnace lining is scrapped, service life drop more
It is low.
Invention content
In order to solve the above technical problems, a kind of mineral hot furnace furnace lining brick fuel of present invention offer and brickwork joint encapsulation process method, lead to
The gap thoroughly eliminated between tiling brick fuel is crossed, the service life of mineral hot furnace furnace lining is increased substantially.
The technical scheme is that be accomplished by the following way：
A kind of mineral hot furnace furnace lining brick fuel, it is characterised in that：At least one layer of annular groove is embedded on the brick fuel, in the annular groove
Filled with carbon materials, the carbon materials are fixed on by strap in the annular groove.
Based on the above technical solution, can also increase following technical characteristic to be further limited：
Further, the annular groove is dovetail groove.
Further, shellring shape slot is provided on the brick fuel.
Further, the carbon materials are cold ramming pastes.
Further, the width of the strap is more than the width of annular groove.
Further, the carbon materials room temperature is solid, and colloid before this when high temperature eventually becomes solid.
Further, the strap is strap or winding film.
Further, a kind of mineral hot furnace furnace lining encapsulation process method, it is characterised in that：Using any institutes of claim 1-7
The mineral hot furnace furnace lining brick fuel stated builds corresponding dovetail groove alignment between furnace lining phase neighbour's brick fuel by laying bricks or stones, when mineral hot furnace is sent as furnace lining
When electricity production, the high temperature in burner hearth makes the fusing of the carbon materials in all dovetail grooves adjacent two-by-two be integrated, and adjacent brick fuel is connected
It is connected together, realizes sealing.
The present invention advantage be：Cured using the carbon materials in brick fuel annular groove, adjacent brick fuel is close-coupled at
Together, it and then blocks and is leaked under molten iron completely；Namely by thoroughly eliminating the gap between tiling brick fuel, significantly extend mine heat
The service life of stove furnace lining.

Fig. 2 is the A-A sectional views of Fig. 1
Fig. 3 is the brick fuel structural schematic diagram filled with carbon materials；
Fig. 4 is adjacent brick fuel connection figure；
Fig. 5 is brick fuel overall diagram.
It is brick fuel to be marked described in figure 1., is 2. carbon materials filler, is 3. strap.
Specific implementation mode
The present invention is specifically described below in conjunction with the accompanying drawings：
As shown in the drawings, a kind of mineral hot furnace furnace lining brick fuel embeds three layers of dovetail groove of processing on brick fuel（As shown in Figure 1, 2）,
Cold ramming paste is filled in dovetail groove（As shown in Figure 3）, cold ramming paste is consolidated by the strap with width more than dovetail groove width of rebate
It is scheduled in dovetail groove（As shown in Figure 5）, it is bundled together with brick fuel, for protecting cold ramming paste and identifying the position of dovetail groove.
Secondly, when building mineral hot furnace furnace lining by laying bricks or stones, corresponding dovetail groove between adjacent brick fuel is closely opposite（As shown in Figure 4）.
When specific works, when mineral hot furnace power transmission produces, made by the high temperature in mineral hot furnace burner hearth adjacent two-by-two in brick fuel
Cold ramming paste fusing roasting in dovetail groove is integral, and adjacent brick fuel is closely joined together, and promotes between brick fuel without gap, resistance
Sealing is leaked and realized under disconnected molten iron.
In conclusion the present invention is cured by the cold ramming paste filled in brick fuel, closely adjacent brick fuel is linked together,
Enhance the leakproofness between brick fuel, increases substantially the service life of mineral hot furnace furnace lining.
The present invention is not limited to above-mentioned specific implementation modes, in spirit, the premise of purposes and range for not departing from the present invention
Under, several changes and modification can be done to it.Protection scope of the present invention based on be subject to the present invention claim.
