Surface functionalized carbon bonded foam filters have been evaluated with the aid of an industrial steel melt according to their performance to filtrate non‐metallic inclusions. Exogenous alumina based non‐metallic inclusions have been introduced in the steel melt in order to distinguish the influence of the filter surface chemistry on the deposition of non‐metallic inclusions. The used filters have been examined after casting according to the population and chemistry of the deposited inclusions. Based on the deposition results an alumina coating leads to the highest deposition of alumina inclusions.
