Because the proportion of light and titanium special titanium alloy rod cooling solidification, titanium rod casting is casting is particularly important. According to our experience, the sprue setting must take the rough sprue, plural sprue form, sprue diameter should be not less than 4mm wax line to form. Titanium bar quantity casting sprue in 3-4 is appropriate.
钛棒铸造熔模铸道的安插方法既可以采取平行插法，亦可采取侧插法。铸道与熔模相连接处呈扁平状，数根铸道应集中在一起，以利于液态金属的铸入。由于铸造时是采用低温铸造，因而可以不考虑热中心对铸件的影响，但铸道不能有直角出现，且不宜过长。
Titanium rod casting sprue design method can take parallel interpolation method, may be used for lateral extrapolation method. The casting and mould connection is flat, a plurality of sprue should be together, to facilitate the liquid metal casting. The casting is the low temperature casting, thus can not consider the influence of heat center on the casting, but the sprue cannot have right angle, and should not be too long.
