Abstract
The invention discloses a blast furnace molten iron runner flow nozzle. The blast furnace molten iron runner flow nozzle comprises an iron runner shell and a protection brick layer arranged at the outer portion of the iron runner shell. Work layers made of iron runner castable are laid in the iron runner shell. A protection lining is arranged on the outer surfaces of the work layers. Anchoring hanging rings are arranged on the protection brick layer. The blast furnace molten iron runner flow nozzle has the beneficial effects that the protection lining is low in cost and capable of being directly used; after tapping, if molten iron overflows out of an iron runner, residual iron is removed easily, the outermost work layer can be effectively protected, and the service life of the iron runner can be prolonged; manufacturing is easy and convenient, the labor intensity is greatly lowered, and rapid replacement, installation and production tapping can be achieved on the molten iron runner field; erosion resistance, scouring resistance, stripping resistance and thermal shock stability of an molten iron runner flow nozzle prefabricate part to the molten iron are sufficiently improved, and the bursting preventing performance is excellent. The iron passing amount of the work layers of the molten iron runner flow nozzle can be greatly increased, and the service life of the work layers of the molten iron runner flow nozzle can be greatly prolonged.
Description
Technical field
The present invention relates to a kind of blast-melted channel nozzle, belong to refractory material manufacture field.
Background technology
At present, newly-built blast furnace or the blast furnace after blowing-out maintenance, unstable in the initial stage working of a furnace that comes into operation, molten iron viscous flow is bad, flowing velocity in iron runner is low, and when the flow that taps a blast furnace of blast furnace exceeds molten iron flow in iron runner, molten iron can diffuse out cleek after quickly depositing in iron runner.Tap a blast furnace normal after residual ferrum on cleaning iron runner time, residual ferrum with the working lining strong bonded of iron runner, outmost working lining can be uncovered while clearing up residual ferrum, serious can reach 50~80mm, the serious working lining destroying iron runner, shortens the service life of iron runner.
Summary of the invention
(1) to solve the technical problem that
For solving the problems referred to above, the present invention proposes the blast-melted channel nozzle of a kind of function admirable.
(2) technical scheme
The blast-melted channel nozzle of the present invention, including iron runner shell, and is arranged on the protection brick layer of iron runner housing exterior；It is equipped with, in described iron runner shell, the working lining that iron runner castable is made；Described working lining outer surface is provided with protective liners；Described protection brick layer is provided with anchoring suspension ring.
Further, described working lining is made up of magnesia carbon brick material.
Further, described protection brick layer is made up of three grades of high-alumina brick materials.
Further, described protective liners is made up of the material of silicon nitride combined silicon carbide, and its thickness is 100mm.
Further, described anchoring suspension ring are provided with two.
(3) beneficial effect
Compared with prior art, it has the advantages that the blast-melted channel nozzle of the present invention to the present invention, and this protective liners is with low cost, can directly use；If molten iron diffuses out iron runner after tapping a blast furnace; easily clear up when clearing up residual ferrum; outmost working lining can be effectively protected; the service life extending iron tap channel makes simplicity; labor intensity is substantially reduced; the quick-replaceable installation of trough scene can be realized and production is tapped a blast furnace; substantially improve molten iron channel nozzle prefabricated component to the corrosion resistance of molten iron, scour resistance, resistance to flaking, thermal shock resistance; the features such as explosion-proof function admirable, can increase substantially and extend iron and the service life of molten iron channel nozzle working lining.
Accompanying drawing explanation

1-iron runner shell；2-protects brick layer；3-working lining；4-protective liners；5-anchors suspension ring.
Detailed description of the invention
Embodiment 1: the blast-melted channel nozzle of one as shown in Figure 1, including iron runner shell 1, and is arranged on the protection brick layer 2 outside iron runner shell 1；The working lining 3 that iron runner castable is made it is equipped with in described iron runner shell 1；Described working lining 3 outer surface is provided with protective liners 4；Described protection brick layer 2 is provided with anchoring suspension ring 5.
Wherein, described working lining 3 is made up of magnesia carbon brick material；Described protection brick layer 2 is made up of three grades of high-alumina brick materials；Described protective liners 4 is made up of the material of silicon nitride combined silicon carbide, and its thickness is 100mm；Described anchoring suspension ring 5 are provided with two.
The blast-melted channel nozzle of the present invention, this protective liners is with low cost, can directly use；If molten iron diffuses out iron runner after tapping a blast furnace; easily clear up when clearing up residual ferrum; outmost working lining can be effectively protected; the service life extending iron tap channel makes simplicity; labor intensity is substantially reduced; the quick-replaceable installation of trough scene can be realized and production is tapped a blast furnace; substantially improve molten iron channel nozzle prefabricated component to the corrosion resistance of molten iron, scour resistance, resistance to flaking, thermal shock resistance; the features such as explosion-proof function admirable, can increase substantially and extend iron and the service life of molten iron channel nozzle working lining.
