PERICLASE REFRACTORIES ACCORDING TO GOST 4689-94
P-91
Burnt periclase products, made of sintered periclase powders are used for laying of bottoms, slopes and walls of open-hearth and electric-steelmaking furnaces, lining of bottoms and walls of ferroalloy 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.
