Sliding Plate

Slide gate plates in alumina–carbon and alumina–zirconia–carbon materials, with high refractoriness, good chemical stability, resistance to slag and molten metal, and good oxidation and spalling resistance.

Grades / types: 7 grades, HBLT80 to HBMLT80
Specification tables: 2: Alumina carbon sliding plate; Alumina zirconia carbon sliding plate

Product overview

The mainstream sliding plate materials are alumina–carbon and alumina–zirconia–carbon; the requirements of special steel grades have driven a diversified range. Sliding plate brick has high refractoriness, good chemical stability, resistance to slag and molten metal corrosion, and good oxidation and spalling resistance.

Values are given for non-impregnated and impregnated plates.
