PERICLASE-CHROME HIGH REFRACTORY PRODUCTS FOR LAYING OF ARCHES OF STEELMAKING FURNACES ACCORDING TO ACCORDING TO DSTU 2573-94 (GOST 10888-93)

PHSUT

Periclase-chrome arch sealed heat resistant products are used for melting space arch of double open-hearth furnaces with the capacity of 850-900 t, operating with increased relative intensity of bath lancing (8-12m3/(t·h)), with moderate relative intensity of bath lancing (5-7m3/(t·h)), and electric-steelmaking furnaces with the capacity of less than 50 t and more.

The products are laid on wooden pallet, laid with cardboard sheets, protected with cardboard angles along the perimeter, wrapped with stretch-film and bundled with polypropylene strip.
