Conclusions
The “Krasnyi Oktyabr” refractories plant has produced SP-14 and SP-11 type conical chamotte plugs containing 39.77% Al2O3 + TiO2.
The SP-14 plugs were tested in the main ladles of the continuous steelcasting equipment of the Novo-Lipetsk metallurgical plant, the SP-11 type in pony ladles at the “Sarkanais Metallurgs” plant.
The tests demonstrated the superiority of these plugs, i.e., they reduced the proportion of unregulated castings from 23.2 to 3.4% in the main ladles and lowered wear in the pony ladles by 8–9%. These conical chamotte plugs can be recommended, therefore, for use in the main and pony ladles of continuous steelcasting equipment.
