SILICA REFRACTORIES FOR OPEN-HEARTH GLASS FURNACE TOP STRUCTURE LAYING
SPECIFICATION OF UKRAINE 26.2-00191738-002:2005 (WITH AMENDMENTS NO.1,2)

DSK

DSK

Products are intended for open-hearth glass furnace top structure laying.

DSK grade products are recommended for laying in the most critical sections of top structure with maximal temperature 1600°С. The products have high fire resistance and good resistance to corrosion due to volatile components of glass mix furnace-charge.

Arch refractories are of the highest accuracy dimensions (±1mm) that ensure minimal uniform laying joints reducing laying joints corrosion failure.

The products are supplied on wooden pallets interlaid with cardboard, with protected corners, wrapped with stretch film and bundled with plastic strip.
