Remains in play. The flames that spring up around the Sorcerer contain scenes from the future, warning him of what is to come. The Sorcerer can re-roll all failed rolls to hit, to wound and all saves (Armour, Ward, etc). Note that the rolls of the caster's mount are not affected by the spell. Once it is cast, Orange Fire remains in play until the Sorcerer chooses to end it (which he can do at any time), it is dispelled, he attempts to cast another spell, or he is slain.
