Application of refining flux
Along with technology advancing, we found that refining fluxes used for purifying and processing aluminum or aluminum alloy melt and their using method. The invention is characterized in that the raw material method of the refining flux is a powder aggregate composed of the subsequent components by way of mass: 25 to 35% of NaCl, 25 to 35 percentage of KCl, 15 to twenty-five percent of Na3AlF6, and/or K3AlF6, 4 to 10 percent of Na2SO4 and/or K2SO4, 3 to ten% of CaCO3 and/or Na2CO3, 3 to six percent of REF3 and/or RECl3; in which, a mass ratio of NaCl to KCl is 1:1; RE is Ce or la. The refining flux can be completely diffused after entering the melt without adsorption agglomeration and pore plugging, and has the excessive efficient capability for generating dry slag without viscous aluminum melt; even supposing the refining flux has a slight response with aluminum melt, the response merchandise can be removed with slag; the refining flux supplied within the invention has high efficiency of gasoline and slag removing.
The aluminum or aluminum alloy purifying molten is using refining flux and processing method thereof technical discipline
The existing invention relates to the purifying remedy of aluminum or aluminum alloy soften, especially relate to aluminum or aluminum alloy cleansing molten processing refining flux; This refining flux is applicable to that rare gas detail is as the pouring-in aluminum or aluminum alloy cleaning molten processing of the winding-up of the provider.
The great of aluminum or aluminum alloy foundry goods is by the diploma of purification selection of soften. The purpose of filtrating molten is degassing and the nonmetal inclusion of removing as a whole lot as viable within the melt thereby reduces loose, pore in the foundry items, diverse metallurgical imperfections which include being mingled with, and improves the mechanical belongings of foundry items, possibly creates situations for the subsequent method of the strand. The traditional filtrating molten is treated degassing manner and slag removal is well-separated, and the detergent strength of this approach is constrained. more than one cleansing molten generation compound can improve the detergent power of aluminum alloy melt greatly.
