Effect of impurities in titanium sponge

The main impurities in titanium sponge are: iron, oxygen, chlorine, carbon, nitrogen, silicon, etc., their distribution in titanium sponge is mostly uneven, which is representative of sampling of sponge titanium products and product classification, mixed packaging It has a big impact.

The quality of titanium sponge depends on the content of impurities and the uniformity of its distribution, the amount of impurities and the uniformity of distribution, which ultimately affect the mechanical properties of the processed titanium products. From the distribution of sponge titanium impurities, the distribution of chlorine impurity elements is wide, and the distribution of oxygen, nitrogen and iron impurities is concentrated. With the continuous expansion of the capacity of single furnaces, chlorine impurity elements have become a major factor affecting product quality in production. Although the content of oxygen, nitrogen, and iron impurities does not directly cause degradation of the product, the increase in its content causes an increase in the Brinell hardness HB of the product's comprehensive impurity element index, thereby degrading the product.
