Latest Patents

Bolger holds a patent for a "Slag Detecting Device and Method." This device is designed to detect slag in molten metal. It comprises a ladle shroud with a hollow passage that connects a ladle containing molten metal to a tundish. The device features an electrically conductive element positioned in the wall of the hollow passage, which is in electrical contact with the molten metal. The design ensures that if the ladle shroud is electrically conductive, the conductive element is isolated by an insulating sleeve. The electrically conductive element is typically a steel pin, which has a flanged end in contact with the molten metal. This pin is connected to a voltmeter to compare the electrical potential of the molten metal to a ground potential. The electrical potential changes dramatically as slag approaches the conductive element, allowing for effective detection.
