摘　　要：针对铝合金钛添加剂实收率波动的问题,研究了合金钛粉的粒度、种类、钛剂压制工艺及钛剂熔化工艺对钛添加剂的熔解速度和实收率的影响,选取了以合金钛粉为主,氢化脱氢钛粉+海绵钛粉+助熔剂为辅的配方,通过试验在合金钛粉粒度0.42~0.59 mm,液压机压强18~24 MPa,钛剂压块密度2.9~3.1 g/cm^(3)的条件下,钛元素的实收率为95%。The actual yield of titanium additives for aluminum alloy has a fluctuation problem,for the problem,it studied the particle size,types of titanium alloy powder,the effect of titanium additives pressing process and titanium additives melting process on melting temperature and actual yield of titanium additives,then it selected the formula that taking titanium alloy powder as the main material,taking hydrogenated dehydrogenated titanium powder+titanium sponge powder+flux as the accessories,it realized the actual yield of titanium is 95%with the following conditions,the particle size of titanium alloy powder is 0.42~0.59 mm,the pressure of hydraulic press is 18~24 MPa,compaction density of titanium additive is 2.9~3.1 g/cm^(3).
