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*)

在与Deutsche Edelstahlwerke GmbH公司(Deutsche Edelstahlwerke GmbH，简称Deutsche Edelstahlwerke GmbH)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。钢锭铸造过滤系统包括：a)压力注浆浇注喂料器和空心器，由粗晶氧化铝或陶粒浇注料配以含碳功能涂料；b)在加压注浆蜘蛛砖的四个分配口中采用多孔式火焰喷雾过滤组件。此外，还将研究多孔式火焰喷涂起动机浇注管在六流连铸中间包中的应用。随后，将在Dew公司借助自动扫描电子显微镜调查钢的纯度，并在IKGB对耐火材料成分进行尸检。

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.
