Due to the uneven flow of molten steel in the tundish, the slag retaining wall is fast in some places and slow in other places. Especially in the bottom area of the tundish, there is an inactive stagnant area of molten steel. It is difficult for inclusions to float in order to fully and effectively utilize the tundish volume to promote the floating of inclusions. The measure taken is to set up a slag retaining wall mold in the tundish. The functions of the slag retaining wall mold are as follows: The slag retaining wall mold eliminates the dead zone in the bottom area of the tundish. The slag retaining wall mold improves the flow trajectory of the molten steel so that the molten steel flows along the steel slag. The interface is shortened to shorten the floating distance of inclusions, which is beneficial to slag absorption
The slag retaining wall mold promotes reasonable heat flow distribution and minimizes the temperature difference of molten steel at each nozzle.
The slag retaining wall mold limits the strong eddy current caused by the impact of the ladle injection flow to a local area to prevent the turbulent diffusion from causing surface fluctuations and drawing the molten slag into the molten steel. Setting up a slag retaining wall is conducive to promoting the separation of steel slag, blocking the molten slag from entering the crystallizer, and the slag retaining wall mold is conducive to the reasonable distribution of the steel flow field in the tundish and the floating of inclusions in the molten steel, improving the purity of the molten steel. The slag retaining wall mold is conducive to improving the continuous casting billet. quality
