Tundish and gunning mixes - TRIGUN
Tundish mixes are produced of magnesia, olivines, mineral and organic fibres and special additives on the advanced technological line. They are applied by slurry gunning in tundishes, where the mix is projected on the tundish walls and bottom creating working lining. They are dispatched as dry mixes packed in big bags.
Gunning mixes are manufactured of bauxite, andalusite, calcinated fireclay, plastifying agents and other additives. They are applied by gunning as repair materials to supply worn areas on refractory linings. They are packed in paper or big bags.
