摘要：

An integrated technology has been developed for obtaining continuous-cast slabs to be used in rolling plates for critical applications. Special filtration elements are installed in partitions inside the tundish to reduce the content of nonmetallic inclusions in the continuous-cast semifinished product. A channeled ceramic lance for injecting the steel with argon has been developed and installed in the bottom of tundishes to remove nonmetallic inclusions 20 μm or smaller. Metallographic studies confirm the effectiveness of the new technology for obtaining plates of high-strength steels.
