STOPPER REFRACTORIES FOR STEEL TEEMING FROM LADLE ACCORDING TO DSTU GOST 5500:2006
SHGSP
Chamotte-graphite stopper oven refractories are used for steel teeming from ladle.The difference between the maximal and minimal values of open porosity in one lot of the SHGSP products shall not exceed 5%.
The products 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.
