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.

在与Deutsche Edelstahlwerke GmbH（DEW）公司的转让项目中，应研究用于铸钢工艺的新型过滤系统，以去除非金属夹杂物。用于铸锭的过滤系统包括：a）基于粗粒氧化铝或耐火粘土浇注料的压力注浆喂料器和空心件，所述粗粒氧化铝或耐火粘土浇注料具有含碳功能涂层; b）在压力注浆蜘蛛砖的四个分配器开口中的多孔火焰喷涂过滤组件。此外，还将研究多孔火焰喷涂启动器浇注管在六流连铸机中的应用。随后，将在DEW公司借助自动扫描电子显微镜对钢的纯度进行调查，并在IKGB对耐火材料部件进行尸检。
