Splashing is a phenomenon often seen in the top-blown converter blowing process. The hazards of splashing are as follows:
(1) Metal loss caused by splashing is 0.5% to 5%. Avoiding splashing is equivalent to increasing steel production.
(2) Splashing smoke pollutes the environment.
(3) The splashed ejecta accumulates and is difficult to remove. Severe splashing can cause accidents and endanger personal and equipment safety.
(4) Due to the large amount of spatter ejected, it not only affects the removal of P and S, increases heat loss, but also causes changes in the amount of molten steel, affecting the stability of smelting control. Limit the increase in oxygen supply intensity.
Preventing and reducing splashing is one of the important issues in top-blown converter stainless steel blower volute.
The density of molten steel in the furnace is about 7.0t/m3, and the density of slag is about 3.2t/m3. Without sufficient power, metal and slag will not be ejected from the furnace mouth.
Splashing is mainly caused by the unbalanced reaction of carbon and oxygen. A large amount of CO gas is generated instantly and escapes from the furnace mouth, pushing the metal and slag out of the furnace.
Explosive splash, foamy splash and sheet metal enclosure are common splashes in oxygen top blowing converter blowing.
