Abstract
The utility model discloses a novel composite working layer of main iron runner of blast furnace, which comprises an Al2O3-SiC-C matrix piece and a Si3N4-SiC or Sialon-SiC composite piece. The composite piece is positioned at an easy-to-damage site inside the matrix piece. The utility model has the advantages of good resistance to the corrosion of blast furnace slag, strong resistance to the erosion of molten iron, and high iron throughput. The utility model is particularly used as working layer of runner wall at the iron-settling site in the anterior half section of the iron-storage main iron runner, to solve the problem of serious damage of the working layer at this site. With the novel composite working layer, the iron throughput is increased while the consumptions of fireproofing material and cost are reduced.
Description
Technical field
The utility model relates to a kind of blast-melted effusive device that is used in metallurgy industry, relate in particular to the casting house tap drain working lining of the composite structure that a kind of high temperature resistance washes away, corrosion resistance is strong.
Background technology
The molten iron and the slag that come out from blast furnace iron notch at first enter tap drain, and high temperature liquid iron and slag fall into behind the tap drain and form an impact zone around the iron spot that falls, and tap drain both sides furrow bank is washed away by molten iron and the erosion of slag in the impact zone scope, and its damage speed is very fast.Present many tap drain working linings all are to use cast-in-site to form, and its material is Al
2O
3-SiC-C matter mould material, this material at high temperature intensity is not high, high temperature liquid iron wash away and the erosion of slag under damage very fast, so too early damage of tap drain impact zone, the work-ing life of seriously having reduced tap drain.
Summary of the invention
In order to solve the problem of above-mentioned existence, the purpose of this utility model provides the casting house tap drain working lining that a kind of high temperature resistance, anti-molten iron scouring capability reach the strong composite structure of slag corrosion resistance ability by force.
The technical solution of the utility model is as follows: a kind of casting house tap drain working lining of composite structure, comprise matrix part, and the serious position of damage is inlaid with the anti-erosion-resistant complex component that washes away in matrix part.
Described complex component is embedded on the two side of matrix part.
Described complex component adopts the anti-material of washing away, and as silicon nitride combined silicon carbide brick or Sailong and silicon carbide combined brick, still adopts Al at other matrix position
2O
3The cast of-SiC-C matter mould material forms.
Compared with prior art the beneficial effects of the utility model are: adopted Si at the serious position of damage
3N
4In conjunction with the SiC brick, utilize Si in conjunction with SiC brick or Sialon
3N
4In conjunction with SiC brick or Sialon in conjunction with SiC brick good high-temperature intensity, good anti-molten iron scouring capability and slag corrosion resistance ability, the local weak part of strengthening the tap drain working lining, thus improve the iron influx of tap drain greatly; Al is still used at other position
2O
3The cast of-SiC-C matter mould material forms, and cost was relatively low thereby the life-span of whole working lining was both grown.
Description of drawings
Fig. 1 is the utility model structural representation
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of casting house tap drain working lining of composite structure comprises matrix part 2, and the serious position of damage is inlaid with complex component 1 in matrix part 2.Preferred complex parts 1 are embedded on the two side of matrix part 2.
Damage serious position complex component 1 and adopted Si
3N
4In conjunction with SiC or Sialon based on silicon carbide brick, adopt Al at matrix part 2
2O
3The cast of-SiC-C matter forms.
Composite component 1 is the raw material with the silicon carbide of SiC 〉=97%, through mechanical pressing, places the nitrogenize kiln, and made Si is burnt till in nitrogenize under 1450～1500 ℃ of high temperature nitrogen atmosphere
3N
4In conjunction with SiC brick (Si
3N
4〉=20%, SiC 〉=70%) or Sialon in conjunction with SiC brick (N 〉=5%, SiC 〉=70%).Matrix part 2 is to make raw material through mixing the refractory castable that forms, Al in the matrix part 2 with electric smelting compact alumina, fused white corundum, brown corundum, silicon carbide, carbon, alumina powder, refractory cements
2O
3Content be 60～80%, the content of SiC is 15～35%, the content of C is 1～3%.
Install mould during construction earlier, parts 1 are in place and fix, again with matrix part 2 cast, the injection body sclerosis demoulding to be poured can be come into operation after 1000 ℃ of bakings.
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all embodiments.And these belong to conspicuous variation or the change that spirit of the present utility model extended out and still are among the protection domain of the present utility model.
Claims (2)
1. the casting house tap drain working lining of a composite structure comprises the basic element of character, it is characterized in that the position is inlaid with the anti-erosion-resistant complex component that washes away in matrix part.
2. the casting house tap drain working lining of a kind of composite structure according to claim 1 is characterized by on the two side that described complex component is embedded in the basic element of character.
