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 16t and 21t, the contraction rates of titanium lumps are 37% and 55% respectively; the average height of titanium lumps formed at high feeding speed (approximately 630kg/h) is 7cm higher than that at low feeding speed (approximately 420kg/h); the contraction rates of titanium lumps formed in 50~60h and 60~70h 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.
