Description
Technical field
The present invention relates to desulfurizing iron pretreating process technical field, more particularly to a kind of steel in category iron and steel metallurgical industry
Metallurgy is desulfurization rifle castable refractory with refractory material.
Background technology
Stirring desulphurization method is that the literary field iron of nippon began one's study in 1963, and nineteen sixty-five is applied to industrial production
A kind of External Desulfurization Technique From Melten Iron.The sulfur method has desulfuration efficiency high, and sorbent consumption is few, and the activity duration is short, metal
Consume the low feature of low and refractory consumption rate.The seventies in last century, China's Wuhan Iron and Steel Plant introduces stirring desulphurization from nippon
Technology, the stirring desulphurization production line that other domestic enterprises also introduce in succession or prepared by designed, designed, has opened up China's desulfurizing iron
The new frame of technology development.
Rifle is stirred for one of capital equipment needed for desulfurizing iron pretreatment in smelting iron and steel technique, stirring rifle is because using bar
Part is more harsh.It is agitator steel construction inside agitator, several longevity may be reused in outside pouring fireproof material, steel construction
The life cycle, and refractory material outside then needs a life cycle once to be poured into a mould again；With desulfurized effect and the need of degree
The need for asking raising, stirrer life used and can not meeting current production, the life-span is shorter, have impact on being smoothed out for production, city
It is badly in need of a kind of long-life stirring desulphurization rifle castable on.
The content of the invention
It is desulfurization rifle refractory material that the present invention, which provides a kind of Ferrous Metallurgy with refractory material, more particularly to desulfuring spray gun makes
Castable refractory, mainly solves existing agitator i.e. desulfuring spray gun because corrosion resistance is poor, and molten iron corrodes serious, anti-thermal shock
Property difference causes structure spalling, the problem of thermal spalling etc. causes the life-span shorter.
In order to solve the above technical problems, the technical scheme is that：The parts by weight of sillimanite 10~20；Ti3AlC31-3 weights
Measure part；The parts by weight of calcium hexaluminate 10~20；White fused alumina 10-20 parts by weight；Pink fused alumina 5-15 parts by weight；Sillimanite micro mist 5-10 weights
Measure part；Copper and iron Spinel micropowder 3-5 parts by weight；Aluminium riched spinel powder 3-8 parts by weight；The parts by weight of nickel oxide powder 3~5, fine aluminium acid
The parts by weight of calcium cement 2~5, alumina gel powder 2-4 weight powder；The outer parts by weight of doping 0.35；Above-mentioned raw materials are carried out according to proportioning
Mixing, you can obtain a kind of desulfurization stirring rifle castable（Content of material refers to that weight contains to the present invention unless otherwise specified
Amount）.
Wherein it is preferred to, sillimanite aluminium content >=60%.
Wherein it is preferred to, calcium hexaluminate aluminium content >=70%.
Wherein it is preferred to, white fused alumina aluminium content >=90%.
Wherein it is preferred to, aluminium riched spinel aluminium content >=78%.
Wherein it is preferred to, alumina gel powder purity >=99%；Ti3AlC3Purity >=99%.
Wherein it is preferred to, the additive is sodium tripolyphosphate, explosion-proof fiber, three kinds of metallic aluminium powder are combined.
Beneficial effects of the present invention：Refractory material of the invention is according to the technical process and agitator of molten iron stirring desulphurization
The design feature of itself, it is primary raw material to select the refractory raw material used in the present invention, and it is good to obtain a kind of corrosion resistance, resistive connection structure
Peel off and Spalling resistance can be good, a kind of long-life desulfurization stirring rifle castable.
The present invention desulfurization rifle castable under the use condition of molten iron stirring desulphurization, using sillimanite aggregate,
Ti3AlC3And fine powder, pink fused alumina, improve desulfurization stirring rifle volume stability and anti-slag ferrum property, it is to avoid stirring rifle, which shrinks, to be opened
Split and hang the defect of scum.
Present invention addition aluminium riched spinel, copper and iron spinelle effectively improves the bonding state between aggregate and powder, carried
The high matrix bond strength of castable refractory, the slag-resistant penetrating power of matrix, and then improve the entirety that rifle is stirred in desulfurization
Performance.
The pure calcium aluminate cement that the present invention is added, alumina gel powder, nickel oxide powder can progressively occur during applied at elevated temperature
Reaction, the superior nickel aluminate of production performance enhances overall performance.Using alumina gel powder and cement collectively as composite junction
Mixture, can improve overall performance, reduce the calcium content introduced.The addition of additive, obtains preferable product workability
With part thermal shock resistance.
It is average under same application conditions using the desulfurization stirring rifle castable function admirable of the present invention, with low cost
Service life reaches 1500 times or so, is 3 times conventional at present of agitator refractory material service life.
