Abstract
The ZrO2 ceramic filter in the steelmaking plant in Nanjing Iron and Steel United Co., Ltd. was studied. Samples were taken from the tundish that ceramic filter installed. The total oxygen content and the type, shape, size, and composition of the non-metallic inclusions in steel were analyzed. Then the inclusion-removing capability of the tundish ceramic filter was evaluated. The results indicate that the effect of the ceramic filter on the filtration of inclusions is striking. The inclusion removal rate was 41.6% when the diameter of inclusions was more than 30 μm. The tundish guaranteed the production of high-quality steel. However, the calcium treatment process should be reasonably controlled to decrease secondary oxidation and improve the cleanliness of molten steel.
