The practice shows that smelting high grade ferrotitanium with rutile by thermite method is feasible.

实践证明，采用金红石热法生产高钛铁在技术上是完全可行。

Thermite is aluminum powder and a metal oxide which produces an aluminothermic reaction known as a thermite reaction.

热是，金属氧化剂，产生我们所热反应。

The pattern of fracture by impact penetration test and tensile fatigue test of thermite welding with stereoscan was observed,and the component of defect with energy spectrum was analyed.

微观缺陷主要包括微孔和夹杂,其中微孔由微气孔和微缩孔组成,夹杂物按形态和尺寸分为团簇状夹杂、锥状夹杂、粒状夹杂、积聚物夹杂、丝状夹杂和混合形夹杂。
