SILICA REFRACTORIES FOR LINING OF OPEN-HEARTH GLASS FURNACE ACCORDING TO SPECIFICATION OF UKRAINE 23.2-00191738-011:2018
DS
Products are intended for open-hearth glass furnace top structure laying.DS grade is recommended for laying of less critical sections of open-hearth glass furnace with maximal operating temperature up to 1530°С.
The products have high fire resistance and good resistance to corrosion due to volatile components of glass mix furnace-charge.
The products are also applied 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.
