Use of Ladle Injection Treatment a Mini Steel Plant

Tahtinen, Kari and Vainola, Reima (1981) Use of Ladle Injection Treatment a Mini Steel Plant. In: Proceedings of International Symposium on Modern Developments in Steelmaking, 1981, NML, Jamshedpur.



During the last ten years ladle injection treatments have been developed at Ovako Oy-Ab. Part of this development has been carried out in co-operation with other Scandi-navian steel works but in many technical & metallurgical problems we have found special applications of our own. At the present time ladle injection is utilised both on billet continuous casting and conventional ingot casting route. The benefits of injection treatments on the process side are improved deoxidation and desulphurisation as well as better castability and surface quality. In addi-tion to these effects that have resulted in better yeild in the process, the ladle injection has many advantages on the properties of the final products. Inclusion cleanness and the control of the inclusion type results in better formability and improved machinability. A strict control of the analysis attained by ladle treatment means e.g. a very narrow Hominy band.
