Description
Technical field
Blast-furnace equipment technical field is the utility model is related to, in specially a kind of iron tap channel operculum colpi of compound castable
Lining.
Background technology
Iron tap channel operculum colpi is one of capital equipment before State of Blast Furnace, above iron tap channel, be to ensure that cast house efficiently, peace
Entirely, the important step of low consumption, environmental protection, smoke stratification, reduction heat radiation when being tapped a blast furnace beneficial to reduction near iron runner, while can also be effectively
Prevent molten iron splash from damaging accident, nowadays operculum colpi is mainly made up of cover board body and castable refractory, and individual layer is heat-insulated, every
Thermal effect is poor, and the temperature change of iron makes operculum colpi deformation big, causes unbalanced stress to weigh, easily castable is come off, when castable comes off
Afterwards, heat is directly radiated on trench cover, causes operculum colpi plate temperature to raise so that operculum colpi short life, but also exist seriously
Potential safety hazard.
Utility model content
The purpose of this utility model is the iron tap channel operculum colpi liner for providing a kind of compound castable, to solve the above-mentioned back of the body
The problem of being proposed in scape technology, possessed beneficial effect are：The new higher flushing resistance, anti-oxidant, anti-slag ability
By force, there is excellent thermal shock resistance, be not easy to peel off, service life length.
To achieve the above object, the utility model provides following technical scheme：A kind of iron tap channel ditch of compound castable
Lid liner, including thermal insulation layer, fixed anchor, working lining, annular lining bar and deep floor, the thermal insulation layer are arranged in shell body
Portion, the thermal insulation layer are internally provided with working lining, and annular lining bar, the annular are provided with inside the thermal insulation layer and working lining
Deep floor is fixed between lining bar and annular lining bar, fixed anchor, the thermal insulation layer and work are fixed with the annular lining bar
The fixation on annular lining bar that layer passes through inside is anchored on shell body.
Preferably, the thickness of the thermal insulation layer is 70-90mm.
Preferably, the thickness of the working lining is 120-160mm.
Preferably, the annular lining bar and deep floor outer surface are set fluted.
Preferably, it is provided with gap between the thermal insulation layer and shell body.
Compared with prior art, the beneficial effects of the utility model are：It is heat-insulated that the equipment sets double-layer composite to protect, every
Thermal effect is good, and thermal insulation layer and working lining are cast on annular lining bar and deep floor so that the new structure is stable, is not easy because outer
Portion's temperature change is fallen off, and is anchored on using fixation on shell body, stable connection, between being left between shell body and thermal insulation layer
Gap, heat insulating function can be given full play to, while reserved gap can effectively eliminate working lining and thermal insulation layer in heated thermal expansion
Shearing force, prevent stress concentration from causing cracking to come off situation, the carbon and silica flour of the working lining addition of cast can prevent slag
Infiltration inside phase material, the corrosion resistance of material is improved, while the thermal shock resistance of material can be improved, avoid the knot of material
Structure peels off and cracking, and the organic fiber of addition can prevent from bursting in baking process in working lining.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Refer to Fig. 1-5, a kind of embodiment provided by the utility model：In a kind of iron tap channel operculum colpi of compound castable
Lining, including thermal insulation layer 2, fixed anchor 3, working lining 4, annular lining bar 5 and deep floor 6, thermal insulation layer 2 are arranged on inside shell body 1,
Thermal insulation layer 2 is internally provided with working lining 4, and annular lining bar 5, annular lining bar 5 and ring are provided with inside thermal insulation layer 2 and working lining 4
Deep floor 6 is fixed between shape lining bar 5, is fixed with fixed anchor 3 on annular lining bar 5, thermal insulation layer 2 and working lining 4 pass through inside
Annular lining bar 5 on fixation anchor 3 be fixed on shell body 1, the thickness of thermal insulation layer 2 is 70-90mm, and the thickness of working lining 4 is
