The growth rate of ring formation increased when titanium-containing powder had been added into Shougang grate-kiln to produce titanium-containing pellets, which had a strong impact on the production processes. In this article, the mechanism and influencing factors of the ring formation problem had been studied, based on sampling and analyzing samples from different parts of kiln. The result indicated that liquid phase of low-melting point and particles were the main reason of ring formation. The ring formation was difficult to clean up because its strength increased in the high-temperature oxidability atmosphere. The desiccation and preheat of green-ball were degraded when the titanium-containing fines had been added. A large amount of powder and particles were produced in kiln because of the lower compressive strength of dry-ball, which led to the rapid growth of rings. |
