The translationThe summary summary invention patent: "method to suppress foaming of molten slag and method for manufacturing products of scum.It is provided a method for refining hot metal with the use of a refining furnace of the type converter by a step of discharging slag is interposed between two stages of refining oxidation in succession, can suppress effectively.The foaming of molten slag discharged in a vessel for receiving the molten slag from a blast furnace of refining the type converter in the stage of discharging slag intermediate and, in this way, the step of discharging slag is interposed in a short time.A water jet 8 is injected into the slag received in a vessel for receiving the molten slag and during unloading of the slag and / or after discharge the slag in the stage of discharge of slag is interposed so that a quantity of movement of the water jet 8 per unit ' MPO is 50 kg m / S2 or more and, thus,The flow of slag through which water droplets are involved in foam slag and the foaming of the slag is removed. The water droplets dispersed in the slag are dragged and evaporated and expanded fragmenting, thereby, bubbles in the slag in a state of foaming.As a result, a gas contained in a bath of slag 6 in a state of foaming is discharged to the outside of the bath of slag 6 in a state of foaming and, therefore, the foaming of the slag is removed.
