We smelt AlMnSiTi alloy in intermediate frequency induction furnace with orthogonal experiment. During the experiment, smelting parameters such as smelting temperature, smelting time, material particle size, slag basicity and manganese-rich slag ratio were adjusted to lead to electricity decrease. The conclusion are follow,①During remolding melting with Mn-Si alloy as main material, we got the optional process technology parameters: smelting temperature adopts 1600℃, smelting time is 8min, covering agent accounts to 10%, Si-Mn alloy particle size is between 10 ~ 20mm, aluminum block size is between 30 ~ 35mm, titanium-iron particle size is between 5 ~ 10mm. adopting this program, smelting unit power consumption can be reduced to 5056kW ? h / t and energy saving is up to 9.4%.②With the carbothermal reduction process with manganese ore and manganese-rich slag as main material, The optional parameters were obtaind following: smelting temperature adopts 1600℃, smelting time is 12min, Mn-rich slag accounts to 20% ratio, slag basicity adoppts 0.7. Adopting this program, smelting unit power consumption can be reduced to 7132kW ? h / t and energy saving is up to 4.9%.③AlMnSiTi alloy got by the test had dense structure, good qualitiy, whith was reaching to the requirement of"863 National supporting Project". The alloy contains aluminium accounting to 12-18% and titanium accounting to 3~8%.④When AlMnSiTi alloy production line is designed, it is suggested that DC Electricity submerged arc furnace and hollow electrode technology to be adoptd. Thus, power consumption could be decrease more.
