Abstract
The utility model discloses a working lining repairing layer of a blast furnace swinging chute. The blast furnace swinging chute comprises a housing, a brick layer, a permanent lining layer and a working lining layer, wherein the brick layer is packaged by the housing; the permanent lining layer is packaged by the brick layer; and the working lining layer is packaged by the permanent lining layer; the blast furnace swinging chute is characterized by further comprising a repairing layer, wherein the repairing layer is packaged by the working lining layer. Compared with the prior art, the blast furnace swinging chute has the following advantages and beneficial effects of changing the original four-layer structure into five-layer structure, additionally arranging the repairing layer on the innermost layer and avoiding the problem that the repairing layer and the working layer are not combined closely after the repairing, so that the service life of the repaired blast furnace swinging chute is prolonged.
Description
Technical field
The utility model relates to fire resisting material field, particularly a kind of blast furnace oscillating chute working lining repair layer.
Background technology
When damage appears in blast furnace oscillating chute working lining, need overlap and water repairing, repairing is carried out change chute after having gone out iron after, at first iron and slag remaining in the chute are cleaned out, manually smear repairing then, through the oscillating chute working lining after repairing, working lining increases work-ing life, the consumption of ton iron reduces, and chute work liner repairing can prolong the life-span of chute.Under the prior art, it mainly is to exempt to toast ramming mass and low cement deposit material that big-and-middle-sized blast furnace oscillating chute working lining is repaired anti-material, but these patching materials all can not reach its desirable service requirements.There is too short problem in work-ing life in ramming mass, and closely knit relatively because the ditch lining refractories of ramming generally is ditch basal surface one deck, poor with following position, top layer associativity, abrasion resistance is poor.Low cement deposit material is owing to need maintenance after the construction, and the construction period time lengthening can not rapid drying and baking, the problem that influence is used.These materials are shorter work-ing life in addition, after the repairing, hang the iron dry slag owing to remain in the mould material surface on working lining top layer, make and repair that one of formation is difficult to bonding closely knit interface between the bed of material and the former working lining, in use, molten iron can be penetrated into wherein gradually, after acquiring a certain degree, repair material can be peeled off by washing away of molten iron integral body, about ten thousand tons of general iron influx 4-5.It is too frequent that patching material weak point in work-ing life causes the wobble groove working lining to repair.The reparation construction labor strength is big, and the environment of high heat causes multiple unsafe factor again, and frequent maintenance is repaired the oscillating chute working lining and caused quality more to be difficult to guarantee.Along with iron-smelting blast furnace to large scale development, also more and more higher with the requirement of refractory materials use properties to the oscillating chute working lining, present big-and-middle-sized oscillating chute working lining patching material generally uses the low cement deposit material of the Al2O3-SiC-C matter of high-quality, one time iron influx develops into ten thousand tons of 6-8 by ten thousand tons of initial 4-5, according to the influence of its processing parameter in the anti-material use of oscillating chute working lining is thought: repair the erosion that mould material not only will stand high temperature sludge iron, the crackle of pour mass under the rapid heat cycle environment, bear the abrasion resistance of slag flowing molten iron, the also rapid construction of necessary raising work lining repair material, quick baking, requirement such as come into operation fast.
Summary of the invention
Problem to be solved in the utility model is:
1, solves blast furnace oscillating chute working lining and repair short problem of life-span;
2, solve existing blast furnace oscillating chute working lining reparation construction problem long in time limit.
As follows for addressing the above problem scheme of the present utility model:
The utility model also proposes a kind of blast furnace oscillating chute, comprises shell, shell hanger, brick layer, permanent lining, work lining, repair layer, and shell coated brick layer, brick layer wrap up permanent lining, permanent lining parcel work lining, work lining parcel repair layer.Repair bed thickness 15-30cm, made by refractory materials.
The utility model compared with prior art has the following advantages and beneficial effect: the utility model makes 5 layers into by 4 layers of original structure, and increased repair layer at innermost layer, occur repair layer after having avoided repairing and be combined closely knit inadequately problem with working lining, thereby prolonged repairing back work-ing life of blast furnace oscillating chute.
Description of drawings
Fig. 1 is the structural representation of the utility model oscillating chute.
Embodiment
Below in conjunction with Figure of description the utility model is described in further details.
A kind of blast furnace oscillating chute as shown in Figure 1, comprises shell 1, shell hanger 2, brick layer 3, permanent lining 4, work lining 5 and repair layer 6.Shell 1 coated brick layer 3, the permanent lining 4 of brick layer 3 parcel, permanent lining 4 parcel work linings 5, work lining 5 parcel repair layer 6.Repair layer 6 thickness are 15cm-30cm, and repair layer is made by refractory materials.
Claims (3)
1. blast furnace oscillating chute, comprise shell, shell hanger, brick layer, permanent lining, work lining, shell coated brick layer, brick layer wrap up permanent lining, permanent lining parcel work lining, it is characterized in that, also be included as repair layer, work lining parcel repair layer.
2. blast furnace oscillating chute as claimed in claim 1 is characterized in that, described repair layer thickness is 15cm-30cm.
3. blast furnace oscillating chute as claimed in claim 1 is characterized in that, described repair layer is made by refractory materials.
