摘要
随着钛工业技术的迅猛发展,海绵钛作为钛材加工领域的核心原材料,其结构特性已成为评估性能的关键指标。本文介绍了镁热法生产海绵钛的形成机理,通过对生产过程中钛坨高度的测量,研究了其在形成过程中结构特性的变化。研究结果发现:加料量为16 t和21 t时,钛坨收缩率分别为37%和55%;高料速(630 kg/h)比低料速(420 kg/h)形成的钛坨平均高7 cm;蒸馏时间50~60 h和60~70 h的钛坨收缩率为33%和41%,表明加料量越多、加料速度过低、蒸馏时间越长,不利于疏松海绵钛结构的形成。本文揭示了这些参数如何影响钛坨高度的内在机制,并针对性地提出了优化海绵钛结构的策略和方法。
With the rapid development of titanium industry technology,titanium sponge,as the core raw material in titanium material processing,its structural characteristics have become the key indicators for performance evaluation.The paper,based on the generation principle of titanium sponge,studies the changes in its structural characteristics during the formation process by measuring the height of titanium lumps in the production process.The research results show that when the feeding amount is 16 t and 21 t,the contraction rates of titanium lumps are 37%and 55%respectively;the average height of titanium lumps formed at high feeding speed(approximately 630 kg/h)is 7 cm higher than that at low feeding speed(approximately 420 kg/h);the contraction rates of titanium lumps formed in 50~60 h and 60~70 h of distillation are 33%and 41%respectively.It can be seen that too low feeding speed,too much feeding amount and too long distillation time are not conducive to the formation of loose titanium sponge structure.Through in-depth analysis,the paper reveals the internal mechanism of how these parameters affect the height of titanium lumps,and proposes strategies and methods for optimizing the structure of titanium sponge in a targeted manner.
