“…as mentioned earlier treating ladle shroud as a flow control device which has an effect on liquid steel behaviour is one of the subjects on which scientists' attention is focused. Finding the right ladle shroud is a complex task, which consists of, among others, determination of share of individual flows, liquid steel impact on slag layer, impact of pouring stream on tundish refractory lining, nonmetallic inclusions removal, temperature distribution in tundish or calculating of the transition zone and the mass of the slab with mixed chemical composition [14][15][16][17][18][19][20][22][23][24]35].…”

“…Intensive scientific research popularised the use of trumpet (TLS) [14][15], dissipative (DLS) [16][17][18] and swirling ladle shrouds (SLS) [19][20][21] as devices controlling the flow, but the basic feature of these ladle shrouds is that they begin and end with one hole. Several studies have presented an analysis of the impact of modifying the ladle shroud by including a larger number of holes in the shroud, but the obtained results were not sufficiently satisfactory [22][23][24]. The presented article offers a new design of a ladle shroud placed in a one-strand tundish with three holes placed in a special dome separating the steel flow and steeped in a metal bath.…”
