Description
Technical field
This utility model is related to a kind of high temperature recessed slot type combined fireproof brick, belongs to brickwork field.
Background technology
Making of hot environment refractory brick such as existing metallurgy, chemical industry and built by laying bricks or stones multiple, are attributed to following three major types.
One class is that do not have good thermal insulation layer, and good insulating layer material heat conductivity will in 0.2w/ (m.k) below, mesh
Front have rock wool, fiber felt etc. using most this materials.As building by laying bricks or stones of rotary kiln does not just have heat conductivity in 0.2w/
(m.k) adiabator layer below, riveting component had both been contacted a little with cylinder and had had face to contact, and working lining refractory brick and riveting component connect
Touch.Lead to the high-temperature refractory steel that cylinder must be more than 20g, because cylinder runs for a long time at high temperature, antirust paint drops seriously,
Cylinder gets rusty, and oxidation is serious, and it is energy loss that internal heat is dispersed into cylinder, results in the need for consuming more fuel to maintain operating mode
Temperature.Traditional rotary kiln brick shape and building method cannot fix rock wool or fiber felt；Or there are rock wool layer or fibre felt layer
Afterwards, internal refractory brick cannot be fixed.
Two classes are cannot local replacing.As blast furnace, air stove, drying grate, rotary kiln refractory material cannot local replacing.
Because the weight that some are last layer bricks need to be supported by next layer of brick, some are that operational layer brick is built into an entirety, and some are bricks
Interlocking structure and brick between.Some brick energy local replacings, but operational layer brick does not enter hydraulic press shakes high extrusion mo(u)lding and go forward side by side stove
Kiln high temperature is roasted, operational layer brick short life.
Three classes are when top needs to build by laying bricks or stones refractory brick, and conventional technique is to set suspender member, or napex is designed balling-up
Shape or circle, this method need not need not expose the long suspender member of length outside and hanging beam top design globulate or circle.When
One rectangle truck top need to build by laying bricks or stones refractory brick heat-insulated when, hanging beam and the suspender member too side of occupation of land, the rectangle truck top side of being
Shape prevents from dropping it is impossible to set arch brick.
Utility model content
Utility model purpose：In order to overcome the deficiencies in the prior art, the utility model proposes a kind of high temperature is recessed
Slot type combined fireproof brick, by being externally provided with heat-insulation layer in pouring layer, plays good effect of heat insulation, protects steel plate, prolongation makes
Use the life-span.
Technical scheme：For solving above-mentioned technical problem, a kind of recessed slot type combined fireproof brick of high temperature of the present utility model,
Including heat-insulation layer, pouring layer and working lining, described heat-insulation layer is connected with pouring layer by attachment means, and pouring layer is with working lining even
Connect, attachment means sequentially pass through steel plate and heat-insulation layer；Described pouring layer is provided with dovetail boss, and it is recessed that described working lining is provided with dovetail
Groove, dovetail boss is inserted in dovetail groove, and working lining is fixed on pouring layer.
Preferably, described attachment means comprise screw rod and nut, screw rod is fixed in pouring layer, and screw rod sequentially passes through guarantor
Warm layer and pouring layer, by nut by Interal fixation on heat-insulation layer.
Preferably, described heat-insulation layer is rock wool or fiber felt.
Preferably, working lining away from pouring layer one side be arc, when building by laying bricks or stones for top, can save space, to top
Portion's furnace shell profile need not require to be spherical or dome-shaped.
Preferably, described nut outside weld is connected to the spherical seal closure of semicircle of parcel nut, so that working condition pressure exists
0.1Mpa～0.3Mpa, improves sealing grade.
In this utility model, pouring layer side is combined with working lining dovetail groove, and side is according to operating condition design Cheng Ping
Shape or arc, are provided with metal rod, as screw rod in the middle of pouring layer, the material of rod member selects according to operating mode, the trade mark have Q235A,
Q235C, Q345C, Q390A, 304 rustless steels etc..Rod member is used for fixing refractory brick, fixes rock wool or fiber felt.Castable exists
Ambient temperature curing have intensity, need not enter stove high temperature barbecue, internal metal rod also will not because high temperature barbecue deformation, oxidation and
Intensity decreases.
The brick of working lining selects high-alumina brick, diamond spar brick or SiC brick according to operating mode, performance be wear-resistant, pressure, impact resistance,
High temperature resistant, liquid phase in operational layer brick local when high temperature is roasted, and after cooling, liquid phase is connecting to obtain more close and firm between granule.
, in more than 80Mpa, in more than 5.0W/ (m k), fixed beam can not be with operational layer brick for heat conductivity for operational layer brick compressive resistance
When together, stove is fired, because stove kiln temperature is more than 1000 DEG C.Fixed beam nor with operational layer brick contact because meeting
High temperature is imported to and wants on rod member and furnace shell.After treatment, refractory brick compressive resistance at this moment can reach more than 30Mpa, leads
Hot coefficient in 1.0W/ (m k) below, meets the requirement of most operating modes, supporting fixed beam material have Q235A,
, below 150 DEG C of temperature, Q345C steel can be steady for a long time for Q345C or 304 rustless steels, wherein Q235A steel energy long-term stable operation
Surely it is operated in below 400 DEG C of temperature, 304 rustless steels can operate in less than 800 DEG C steadily in the long term.So castable is solid at 110 DEG C
Fixed beam material degeneration is not resulted in while change.
First bake good berth layer brick in stove by design requirement, carry out fixed beam in machine shop, then by setting
Meter requirement makes castable mould, operational layer brick, fixed beam is poured into a mould curing molding in mould, such modular tile completes
?.Scene nut fastens modular tile.So it is layered solve problem.
Screw rod and 2 layers of fixing plate weld, surface is poured into a mould after will removing the impurity such as ash disposal, oil again.Castable and the connection of fixture
Connect and will ensure that certain contact area guarantee fixture and castable consolidate and couple, this is intended to be set according to working condition requirement process
Count and test the data of acquirement.
Beneficial effect：The recessed slot type combined fireproof brick of high temperature of the present utility model, heat-insulated by being externally provided with pouring layer
Layer, by good isolation, steel plate does not run in high temperature the temperature leading to working lining for a long time, and antirust paint will not fall off, and extends
The service life of steel plate；Because polylith refractory brick is coupled together by steel plate, need change when it is only necessary to turn on bolt so that it may
To change refractory brick, it is convenient to change；It is only necessary to the one side of working lining is done camber when needing to build by laying bricks or stones arc top when top,
Connected by steel plate, without suspender member, greatly saved place, improve installation effectiveness.
