    Abstract: A method of sealing a slag drain in a direct smelting vessel is disclosed. Also disclosed are a method of maintaining a slag drain channel and a direct smelting vessel with a slag drain channel that extends through a sleeve of refractory material installed in the direct smelting vessel. The method for sealing the slag drain includes locating a pre-formed refractory material at an inlet end of the slag drain channel so that it is exposed to a molten bath contained within the direct smelting vessel and sealing the slag drain channel with sealing material downstream of the pre-formed refractory material.

    Abstract: Disclosed is a method of starting a molten-bath based melting process for smelting a metalliferous feed material to form a molten metal in a smelting apparatus, with the apparatus including a smelting vessel that includes a main chamber that contains a bath of molten metal that includes establishing a sufficiently large and stable “hot zone” for ignition of oxygen and coal in a main chamber of a smelting vessel by independent means, i.e. independently of and before supplying cold oxygen and coal into the main chamber. The method includes the steps of inserting an external ignition source into the main chamber of the smelting vessel to form a hot zone in the main chamber and commencing supplying a cold oxygen-containing gas into the main chamber and igniting combustible material in the main chamber. The following step commences supplying a carbonaceous material into the main chamber and increasing the temperature in the main chamber and melting frozen materials in the main chamber, and then commences supplying metalliferous material into the main chamber and smelting the metalliferous material and producing molten metal in the main chamber. The method includes supplying a combustible material to the main chamber prior to the first step of inserting the external ignition source into the main chamber. The combustible material is supplied into the main chamber by manually inserting the combustible material through an opening in the main chamber. A combustible material is supplied to the main chamber after inserting the external ignition source into the main chamber and prior to commencing supplying the cold oxygen-containing gas into the main chamber and igniting the combustible material in the main chamber.

    Abstract: Molten iron, slag and feed material for the sulphate process are disclosed. All are products of a 5 direct smelter. Also disclosed is a molten bath-based direct smelting process comprises controlling the process conditions in a direct smelting vessel so that molten slag in a molten bath of metal and slag in the vessel has a viscosity in a range of 0.5-5 poise when the slag 10 temperature is in a range of 1400-1550 C in the molten bath in the vessel.

    Abstract: A direct smelting plant for producing molten metal from a metalliferous feed material is disclosed. The plant includes a fixed smelting vessel to hold a molten bath of metal and slag and a gas space above the bath. The plant also includes means for supplying solids and gas feed materials to the vessel and for tapping molten material from the vessel. The plant also includes at least two platforms for supporting plant operators at different heights of the vessel. The metal tapping means and the slag tapping means are located so as to be accessible by plant operators on a cast house platform and the end metal tapping means and the end slag tapping means are located to be accessible by plant operators on an end tap platform that is at a lower height than the cast house platform.
