Prevention of Red Scale Formation during Hot Rolling of
It was found that surface part of the scale (mainly FeO) was broken to powder by hot rolling at the temperature below 900°C. The red scale of Fe 2 O 3 was formed by the oxidation of powdered scale during cooling. Thick scale formed during slab soaking was completely removed by hydraulic descaling before rolling in low Si steel, whereas that
