Explosive splashing occurs during smelting, usually due to low process temperature, delayed C-O reaction, and slag Σ FeO content of over 20% can cause explosive splashing.
Furthermore, when operating at a high gun position for an extended period of time, when the gun position is high enough to weaken the stirring force of the oxygen stream, the oxygen transfer is carried out through slag diffusion, resulting in local slag Σ Excessive FeO can cause explosive splashing.
Once explosive splashing occurs, some lime or fluorite should be added for pressure thermal spraying, and the spray gun should be lowered immediately to solve the problem. Explosive splashing can cause a significant loss of heat in the converter, worsen the slag forming conditions during the smelting process, and increase consumption. Prevention should be taken in advance.
