PERICLASE REFRACTORIES ACCORDING TO GOST 4689-94

P-89

Burnt periclase products, made of sintered periclase powders are used for laying of bottoms, slopes and walls of open-hearth furnaces predominantly above slag belt, as well as for axis - laying of other high temperature furnaces.

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.
