STOPPER REFRACTORIES FOR STEEL TEEMING FROM LADLE ACCORDING TO DSTU GOST 5500:2006

SHSP-35

Chamotte stopper oven refractories are used for steel teeming from ladle.

The products (except SHSP-35 No.1) herringbone laid on wooden pallet, the layers are laid with cardboard sheets and wrapped with stretch-film. Bag top is fixed with wooden angles, and then the bag is bundled with polypropylene (or polyester) strip.

SHSP-35 No.1 grade product are wrapped into cardboard or paper, wrapped with stretch-film and laid into wooden case with laid along the perimeter cardboard. The layers are laid with cardboard or liner, and the gaps between the products, from case walls and under the cover are filled with wood chips or flakes.
