proteem Covering Powders for Tundish and Ladle
mong Proteem product series its possible to select a suitable material according to operational parameters of each specific application. Generally for tundish application factors affecting product performance result to be steel grade, exposed steel surface to be covered, casting time, and sequence index.
On the other side, regarding ladle applications, critical factors are chiefly the amount and the characteristics of the refining slag.
Increasing demand of better quality steel and subsequent use of high performance basic tundish lining material boosted researching and developing of active basic tundish powders assuring high covering and insulating properties and low corrosion activity.
Moreover effective NMI absorption capability is provided by specific viscosity and surface tension of molten slag layer in direct contact with molten steel.
Plant experience in using these active basic tundish powders gave improved steel cleanness.
