本文研究了Ni基高温合金电渣重熔CaF_2-MgO-Al_2O_3-CaO-0.5mol％TiO_2渣系成分对合金中Mg,Al,Ti含量的影响规律。当渣池温度为1690±10℃时,在0.10≤N_(MgO)≤0.25,0.05≤N_(Al_2O_3)≤0.21,0.05≤N_(CaO)≤0.15范围,建立了以下函数关系。 [Mg]=0.881[Al]_0~(0.641)N_(MgO)~(4.114-2.835N_(CaO)+1.077InN_(Al_2O_3))N_(Al_2O_3)~(1.282),wt-％ [Al]=[Al]_0-(0.19+0.804N_(CaO)~(0.454)-1.70N_(Al_2O_3))vA/45.36V,wt-％ [Ti]与N_(MgO),N_(Al_2O_3)变化无关,它随N_(CaO)增加而略增。
The effect of the composition of slag system CaF_2-MgO-Al_2O_3-CaO-0.5 mol % TiO_2 on the contents of Mg, Al and Ti in Ni-base superalloy during ESR has been investigated. In the mole concentration range of the slag: 0.10≤N_(MgO)≤0.25, 0.05≤N_(Al_2O_3)≤0.21 and 0.05≤N_(CaO)≤0.15, and at temperature of the slag pool about 1690±10℃, the wt-% elementary content in the superalloy after ESR may satisfy the following functions: [Mg]=0.881[Al]_0~(0.641)N_(MgO)~(4.114-2.835N_(CaO)+1.077lnN_(Al_2O_3))N_(Al_2O_3)~(1.282) [Al]=[Al]_0-(0.19+0.804N_(CaO)~(0.454)-1.70N_(Al_2O_3))vA/45.36V v=0.148+0.479N_(Al_2O_3)+0.348N_(MgO)-0.378N_(CaO) where [Al]_0 is the Al content in the electrode; A is the area in cm~2 of the metal pool/slag interface and v or V is the mett rate in kg/min of this study or others respectively. [Ti] increases slightly with the increase of N_(CaO) and without relevance to the variation of N_(MgO) or N_(Al_2O_3).
