Abstract

1494950 Composition SOC EUROPEENNE DES PRODUITS REFRACTAIRES24 Dec 1975 [26 Dec 1974] 52898/75 Heading C1M A lining part for a pusher oven, for reheating steel slabs or billets, comprises at least one alkali metal oxide 0À3-1À5% with optional additions of up to 5% in total of CaO, Fe 2 O 3 , MgO and/or TiO 2 and has a weight ratio SiO 2 /Na 2 O (or molar equivalent of other alkali metal oxide) of not more than 16. The composition has a crystallographic composition, by weight, of and the weight of the zirconia phase plus 2À5 times the weight of the vitreous phase is in the range 33-57À5%.
