Steel ladle is a critical equipment of steelmaking-continuous casting process, which is separated into ingot casting ladle and continuous casting ladle.

　　As the using conditions of steel ladle is different, the requirement for selection of steel ladle refractories is also not necessarily the same, and there also existe differences in service life of linings.

　　Hitech Material can customize a complete set of solutions for steel ladle in this connection.

　　1. Ingot casting ladle

　　(1) Ladle of EAF

　　Permanent layer: fireclay bricks, agalmatolite bricks;

　　Working layer: alumina-magnesia-carbon bricks;

　　Monolithic refractory materials: Al₂O₃-MgO-C well blocks for purging plug of ladle, silica-based stuffing sand, Al₂O₃-MgO refractory mortar.

　　(2) Ladle of converters

　　Permanent layer: calcium silicate boards, high-alumina refractory castables;

　　Working layer:Al₂O₃-MgO refractory castables;

　　Monolithic refractory materials: Al₂O₃-MgO-C well blocks for purging plug of ladle, silica-based stuffing sand.

　　2. Continuous casting ladle

　　(1) Ladle of EAF

　　Slag line: magnesia carbon bricks;

　　Ladle bottom: magnesia carbon bricks, alumina magnesia spinel bricks, magnesia dolomite carbon bricks, alumina-magnesia unburned bricks, unburned high-alumina bricks;

　　Barrel: magnesia carbon bricks, alumina-magnesia-carbon bricks, magnesia dolomite carbon bricks, alumina-magnesia unburned bricks, unburned high-alumina bricks.

　　(2) Ladle of converters

　　For small sized ladle, alumina-magnesia refractory castables are generally used as integral permanent linings.

　　With large and medium-sized ladle, Al₂O₃-MgO or alumina magnesia spinel castables is used as working linings for barrel and bottom.

　　Slag line is built by magnesia carbon bricks.
