- produit antiretassure n. m.
Substance used to delay freezing of molten steel in the feeder head.
The chemical compositions of the different proprietary brands vary considerably, but, in general, they consist essentially of mixtures of carbonaceous matter and irreducible oxides. When placed on the surface of the molten steel, the carbon and any other elements present slowly oxidize, thus generating heat, whilst the non-metallic matter in the powder remains as a residue which serves to insulate the molten metal beneath.
