Functionalized feeders, hollowware, spider bricks and starter casting tubes for increasing the purity in steel casting processes – Carbon-containing functional coatings and flame-sprayed filter components – (T04*)

• Subject Area: Metallurgical, Thermal and Thermomechanical Treatment of Materials
• Term: from 2019 to 2022
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 169148856

In the transfer project with the company Deutsche Edelstahlwerke GmbH (DEW), novel filter systems for steel casting processes shall be investigated regarding the removal of non-metallic inclusions. The filter system for ingot casting comprises:a) pressure slip-casted feeders and hollowware based on coarse-grained alumina or chamotte castables functionalized with carbon-containing functional coatings andb) porous flame-sprayed filter components in the four distributor openings of a pressure slip-casted spider brick.Furthermore, the application of porous flame-sprayed starter casting tubes in the 6-strand continuous casting tundish shall be investigated. Subsequently, the steel purity will be investigated at the company DEW with the aid of an automated scanning electron microscope and the refractory components are examined post mortem at the IKGB.
