Problems solved by technology

[0005] At present, the existing fine powder titanium agent for producing aluminum alloys still has some deficiencies, for example; the existing fine powder titanium agent for producing aluminum alloys does not have obvious synergistic effect of each component in smelting, It cannot play the role of lowering the melting point in the aluminum alloy production process, and cannot change the viscosity of the material, so that the fluidity of the material is weakened, the metal and the slag phase are separated more easily, and the waste of raw materials and energy in the aluminum alloy production process is increased. and the cost of aluminum alloy production, the existing fine powder titanium agent cannot spread on the surface of the aluminum melt, break and adsorb the oxides on the surface of the melt at the melting temperature, the adsorption capacity of the solvent is relatively weak, and it does not have the ability to remove hydrogen , the impurity removal effect is not obvious, which reduces the utilization rate of fine powder titanium
