    Abstract: A method of relining a vessel that is used to carry out a direct smelting process that produces molten metal under conditions requiring molten bath temperatures of at least 1000 DEG C is disclosed. The vessel is of the type that has a floor (3) that is refractory lined, a side wall (5) that is at least partially refractory lined, and a top wall (7), and at least two access openings to the interior of the vessel. The relining method included the steps of cooling down the vessel, gaining access to the interior of the vessel via the access openings, relining the vessel, and re-starting operation of the process in a period of time of 21 or less days.
