SILICA REFRACTORIES ACCORDING TO SPECIFICATION OF UKRAINE 23.2-00191738-010:2018

DN

DN

Silica refractories of DIN grade are used mainly for heat-treatment furnace laying.
In addition, the DIN grade products are applied in glass industry for laying of walls and arch of open-hearth glass furnace regenerators.

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