由钛或钛合金构成的铸块的连续铸造方法
Abstract:
通过控制铸模(2)和铸块(11)的接触区域(16)的铸块(11)的表面部(11a)的温度Ts、和接触区域(16)的从铸块(11)的表面部(11a)向铸模(2)的通过热通量q中的至少一个，将熔液(12)凝固的凝固壳(13)的接触区域(16)的厚度D纳入到规定的范围内。由此，能够铸造出铸造表皮的状态良好的铸块。
Abstract(English):

By controlling the temperature (TS) of a surface portion (11a) of an ingot (11) in a contact region (16) between a mold (2) and the ingot (11) and a passing heat flux (q) from the surface portion (11a) of the ingot (11) to the mold (2) in the contact region (16), the thickness (D) in the contact region (16) of a solidified shell (13) obtained by the solidification of molten metal (12) is brought into a predetermined range. Consequently, an ingot having a good casting surface state can be cast.
