Abstract: A dart has a metal bar (1) passing through a ceramic, shaped, dart head (2) and then through a cylindrical ceramic dart stem (3). A sleeve (4) of a carbonaceous or reactive material is provided about the stem (3) or a layer of that material can be fed on the lower face (5) of the dart head (2) (at the interface of the steel and slag). A block or sleeve (6) of suitable reactive material could be positioned on the top face (7) of the dart. The reactive material could be cardboard or paper, or a reactive metal, such as aluminum or magnesium. In each case a chemical reaction with the molten steel will result in an updraft in the steel which clears slag from the area of the tap hole.

Abstract: An apparatus and method for controlling the flow of molten material from a melt container. The apparatus includes a tubular insert sized for insertion into a tap hole formed in a sidewall of the melt container and a rod receivable within the insert. A cooling device is provided to cool the rod to a temperature below the temperature of the molten material. The rod is axially movable within the insert between a first position wherein the rod is positioned within the tubular insert for cooling a portion of the molten material located at the first end of the insert to form a plug and stop the flow of molten material through the passageway, and a second position wherein the rod is spaced from the first end of the insert to allow the plug to melt and start the flow of molten material through the passageway. A method for trapping gases emitted during the melt and tapping processes is also disclosed.

Abstract: The invention is directed to a dynamic control system that maintains an inert gas feed at a constant target gas flow rate sufficient to prevent or reduce alumina or alloy plugging within a slide gate discharge opening. The dynamic control system includes a gas feed line extending between an inert gas supply and the slide gate discharge passageway, a gas flow regulator, a pressure gauge; and a gas feed flow control that detects an amount of incoming inert gas lost through leaks in the system and adjusts the gas flow regulator in response to the detected amount of incoming gas flow loss so that the adjusted incoming gas feed continues to deliver the target inert gas flow rate to the discharge passageway.

Abstract: A movement sensor comprising an elongate object, comprising a piezoelectric material, having an anchored end that is anchored to a base, and an unanchored end which is free to move in at least two degrees of freedom and to which a force is applied, the unanchored end of the elongated object being configured to move in response to the applied force. A plurality of electrodes are disposed on the elongate object and are configured to cooperate with the elongate object in producing signals usable to determine the magnitude and direction of the movement of the unanchored end due to the applied force. Sensing circuitry is electrically coupled to the electrodes and is configured for processing the signals from the electrodes so as to determine a magnitude and a direction of movement and produce a signal indicative of said magnitude and direction.

Abstract: The invention relates to taphole closures for furnaces and more particularly to an automated means of presenting the taphole closure means to a furnace. Taphole closures in the form of darts with elongate tails are known, and given their weight are difficult to present to a transport arm. The object of the invention is to overcome this difficulty, an objective met by a means of loading a taphole closure means into a steelmaking vessel comprising a holder for at least one taphole closure means to hold the or each taphole closure means with an uppermost rod substantially vertical, lifting means able to engage the uppermost rod and lift the taphole closure means, control means to bring the lifting means to the taphole closure means in the holder and to cause further movement of the lifting means to bring the taphole closure means to the location of and into contact with a releaseable clamp means at the end of a transport arm, means to cause the lifting means to disengage from the uppermost rod and activate the releaseable clamp, and a means of moving the transport arm from a position of rest where it receives the taphole closure means to a position where it can be inserted into a steelmaking vessel to load the taphole closure means into the vessel.
