SILICA REFRACTORIES FOR LINING OF OPEN-HEARTH GLASS FURNACE ACCORDING TO SPECIFICATION OF UKRAINE 23.2-00191738-011:2018

DSU

DSU

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

DSU grade is recommended for laying of the most critical sections of top structure open-hearth glass furnace in the areas of melting and maximal temperatures. The products have high fire resistance and good resistance to corrosion due to volatile components of glass mix furnace-charge.

Interconnected porosity for products with weight up to 35kg is not more than 20%, and for products with weight more than 35kg - not more than 21%.

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