Description
REFRACTORY MATERIAL FOR SMELTING TITANIUM-ALUMINUM
ALLOY AND METHOD OF PREPARING SAME
FIELD OF THE INVENTION
The disclosure relates to the technical field of titanium-aluminum alloy smelting. in particular to a refractory material for smelting titanium-aluminum alloy and method of preparing same.
BACKGROUND
As a preferred material for ultra-high speed aircraft and next-generation advanced aero-engines, titanium-aluminum alloys has excellent performances like low density, high specific strength, high specific rigidity, good heat resistance, excellent high temperature creep resistance and good oxidation resistance. The melting titanium-aluminum alloy has high chemical activity under high temperature and is easy to react with refractory materials, resulting a pollution of all the melting body. Therefore, the development of refractory materials for smelting titanium-aluminum alloy has become one of the most important problems in this field.
Currently, alumina oxide, calcium oxide, zirconium oxide, yttrium oxide and perovskite materials are commonly used as refractory material for smelting titanium-aluminum alloy.
For alumina oxide materials, Fan et al disclosed (Fan J, Guo I, Wang 5, et al. microstnictural evolution and interfacial reaction of TiAl-Si alloy consolidated in aluminous acceptable [J]. Materials Science and Technology, 2015, 31 (14): 1727-1734.) and Liu et al (Liu D, Li X. Su Y, et al. microstructure evolution in directionally consolidated Ti -(50,52)at% Al alloys [J]. 2011,19 (2): 175-181.) a method for smelting the titanium-aluminum alloy by using alumina oxide material. However, the chemical stability of the alumina oxide materials is poor, which was closely related to the reaction behavior of the titanium-aluminum alloy and the composition of the titanium-aluminum alloy. There are certain limitations on the types of alloy that can be used.
Description
For calcium oxide materials, a patented technology entitled "Preparation method of CaO refractory material and crucible for titanium alloy smelting" (CN101830715A) disclosed that 82-92mo1% calcium oxide micro-powder, 5-15mol% zirconium oxide micro-powder and 1-5mot% titanium oxide micro-powder are used as raw materials for preparing CaO refractory material and crucibles for smelting titanium alloys; Li et al. (Li CH, He J, Zhang Z, et al. Preparation of TiFe based alloys melted by CaO crucible and its hydrogen storage properties [J]. Journal of Alloys and Compounds, 2015, 618: 679-684.) disclosed that a calcium oxide with 97wt% CaO content is prepared by isostatic cold pressing. However, the hydration resistance of the calcium oxide was poor, which easily leads to the increase of oxygen in the alloy and the contamination of the titanium alloy.
For zirconium oxide materials, a patented technology entitled "Zirconium oxide crucible for precision casting and heat treatment method thereof' (CN109516802 A) discloses that the zirconium oxide crucible are prepared by using zircon powder with different particle diameters as raw materials. Chang et al. (Chang YW, Lin CC. Composite dependence of phase formation mechanisms at their interface between titanium and calcia-stabilized zirconi a at 1550 °C[J]. Journal of the American Ceramic Society, 2010, 93 (11): 3893-3901.) use 95moN zirconium oxide and 5moi% calcium oxide as raw materials for obtaining the calcium oxide material for smelting the titanium-aluminum alloy. However, the zirconium oxide material has poor chemical stability and would react with titanium to produce a solid solution, thereby causing contamination of the alloy.
For yttrium oxide material, a patented technology of "Method for preparing crucible for smelting titanium and titanium alloys" (CN101381242A) uses yttrium oxide and an appropriate amount of additive as main raw materials, and adopts isostatic pressing method or pouring process method to prepare yttrium oxide crucibles for smelting titanium and titanium alloy. The patented technology of "Electric melting yttrium trioxide ceramic crucible for titanium alloy melting casting and preparation method thereof' (CN106116578B) uses yttrium oxide and zirconium as main raw materials for preparing the electric melting yttrium trioxide ceramic
Description
crucible for titanium alloy melting casting by the electric melting method. However, the thermal shock resistance of the yttrium oxide material is poor and the service life is short.
As for perovskite materials, a patent entitled "BaZr03 refractory material for smelting titanium alloy and preparation method of crucibles" (CN102503489A) and the patent of -17203 doped BaZr03 refractory material" (CN105777162A) disclosed that BaZr03 refractory material for melting titanium alloys is prepared by using barium carbonate and zircnium oxide as raw materials However, the chemical stability of perovskite materials is still defective, and the smelting results in contamination of titanium aluminum alloys and high oxygen content.
SUMMA RY
In order to overcome that drawbacks of the prior arts, the aim of the disclosure is to provide a low cost and simple preparation method of refractory material for smelting titanium aluminum alloy. The refractory material for smelting titanium aluminum alloy by the method has good chemical stability at high temperature, good thermal shock resistance, strong melt resistance to the titanium aluminum alloy and little pollution to the titanium aluminum alloy.
In order to achieve the aim, the technical scheme adopted by the disclosure is as follows.
A method for preparing a refractory material for smelting a titanium-aluminum alloy is disclosed. The method includes uniformly mixing a matrix material of 25-40 wt% titanium-containing calcium hexaluminate fine powder, adding the uniformly mixed matrix material into an aggregate of 60-75 wt% titanium-containing calcium hexaluminate particles, and mixing uniformly, adding a binder having 0.5-2 wt% of a total amount of the aggregate and the matrix material, mixing and milling and pressing molding under 100-200 MPa, conducting heat preservation for 20-36 hours under 110-200 °C to obtain the refractory material for smelting the titanium-aluminum alloy.
