ALUMINA AND HIGH-ALUMINOUS REFRACTORIES ACCORDING TO GOST 24704-94

MKS-72

MKS-72

Mullite-corundum refractories are predominantly used at construction and repair of open-hearth furnaces, for laying of blast-furnace bottom, for laying of shafts, cones of blast furnaces, open-hearth glass furnace, furnaces for various metals melting.

The products are laid on wooden pallet, laid with cardboard sheets, protected with cardboard angles along the perimeter, wrapped with stretch-film and wrapped with polypropylene strip.
