CHAMOTTE AND SEMIACID REFRACTORY PRODUCTS OF GENERAL PURPOSE ACCORDING TO GOST 390-96
PL
According to physical and chemical parameters the products meet the requirements for the grade SHA-1 (Al2O3 content, fire resistance and interconnected porosity).PL grade refractory products are shaped and extra complex.
They are applied in metallurgy for uphill steel teeming.
The products are produced in accordance with the customer drawing.
The products are laid on wooden pallet, laid with cardboard sheets, wrapped with stretch-film and wrapped with polypropylene strip.
