Domain.
Background technique:
In the entire material system of refractory material, other than oxide-based refractory material, carbon containing refractory is with steel
The high-performance Non oxide refractories that iron smelting technique progress is got up are the important composition portions in refractory material classification
Point, the yield and reduction that good resistance to slag corrosion and thermal shock resistance can be significantly increased metallurgical furnace life, increase steel
Refractory material unit consumption, economic benefit and social benefit are significant.Exploitation novel low carbon non-oxidized substance multiple phase refractory material has become generation
The generally acknowledged important development direction of boundary colleague.The raw materials used nitride or carbon for Si system and Al system of non-oxidized substance multiple phase refractory material
Compound, research shows that Non oxide refractories have to the permeability resistance and anti-erosion of high-temperature slag and metal bath preferably,
The advantage that linear expansion coefficient is low, thermal conductivity and heat-resistant knocking stability are good.Its research system is from Si3N4- SiC, SiAlON-SiC development
To SiAlON/Si3N4-Al2O3/ Spinel and SiAlON/Si3N4-Al2O3/ Spinel-SiC and containing AlN, AlON, MgAlON,
The systems such as TiNC and corresponding composite diphase material, it is primarily used for blast furnace ontology, cast house and molten iron accumulating tank, clean steel
The positions such as ladle, continuous casting are smelted, are played an important role for the safety in production and technological progress of metallurgical industry.
But high cost of material and twice firing high energy consumption cost restrict answering extensively for non-oxidized substance complex phase high-temperature resistant material
With.In recent years, with aluminium silicon systems mineral and it is some be rich in Al2O3The Industrial Solid Waste of component and MgO component is raw material, also by carbon heat
The research that the preparation processes such as original nitridation obtain inexpensive nitride composite fire powder material has become hot spot.Turn in silicate mineral
Type has more experimental study work report in terms of preparing oxide-non-oxidized substance multiple phase refractory material powder, especially containing
SiO2And Al2O3The aluminium silicate mineral of component prepares grinding for SiAlON or SiAlON composite diphase material through carbothermal reduction-nitridation technique
Study carefully aspect and has been achieved with more research achievement.However, containing ZrO with more excellent performance2, the complex phase high-temperature resistants such as ZrN, ZrC
It is expensive for material, is applied only to thermal extremes harshness use condition such as space flight and aviation, hot industry critical component etc..?
ZrO only is used in the site portions such as slide hole and sizing nozzle in refractory material2Material, related ZrN, ZrC etc. are in high-performance
Application in Refractory not yet finds more report, and the mainly difficult reason of price height and preparation is difficult to expanded application.
In addition, the non-oxidized substances such as ZrN, SiAlON object mutually needs just be prepared under the conditions of very high temperature and protective atmosphere
To corresponding high temperature resistant product, it is difficult to which (being usually no more than 1780 DEG C) is sintered under the conditions of usual refractory industry high temperature sintering
At the block refractory material with high intensity.Therefore, it is difficult to be utilized using the technique of the super high sintering temperature of traditional refractory material
ZrN, SiAlON complex phase non-oxidized substance refractory raw material prepare high-performance heat-resisting material product, will also cause high energy consumption and it is high at
This.
The present inventor proposes to prepare ZrN-SiAlON by carbothermal reduction-nitridation using zircon and middle-low grade bauxite
Complex phase non-oxidized substance refractory raw material has the advantage of high-performance and low-cost.It is again combination by aggregate and sucrose solution of SiC particulate
Agent forms carbon combination at high temperature using sucrose to obtain ZrN-SiAlON-SiC-C complex phase fire material.The preparation process
It will be a cost effective way of effective high-tech of preparation high-performance ZrN-SiAlON-SiC-C multiple phase refractory material product
Diameter.
