摘要: Systems and methods for measuring the thermal crown of rolls in-situ (e.g., at high temperature) either inside or outside the rolling mill can include sensors that measure propagation times of mechanical waves through the rolls. In some embodiments, one or more sensors are used to measure the propagation times of ultrasonic waves traveling inside the roll and normal to the roll's axis. These measurements can be taken when the roll is still hot and can be used to determine in real-time the thermal expansion at various points along the roll.

摘要: Disclosed are adjustable kiln flights for rotary kilns and associated methods. The kiln flight includes a base configured to be secured to a rotary kiln surface of a rotary kiln. In some aspects, the kiln flight includes a flight body rotatably supported on the base such that an angular orientation of the flight body is adjustable. In various examples, the kiln flight includes a height adjuster movably supported relative to the base such that a height of the kiln flight is adjustable. A method of controlling a rotary kiln with the adjustable kiln flight includes supporting a kiln flight on a base that is secured to an inner kiln surface of a rotary kiln, and adjusting at least one of the angular orientation of the kiln flight or the height of the kiln flight.

摘要: Systems and methods are disclosed for using magnetic fields (e.g., changing magnetic fields) to control metal flow conditions during casting (e.g., casting of an ingot, billet, or slab). The magnetic fields can be introduced using rotating permanent magnets or electromagnets. The magnetic fields can be used to induce movement of the molten metal in a desired direction, such as in a rotating pattern around the surface of the molten sump. The magnetic fields can be used to induce metal flow conditions in the molten sump to increase homogeneity in the molten sump and resultant ingot.

摘要: Provided herein are systems and methods for containing a viscous material, such as a coolant, on a roll and/or a roll processed engineering material (e.g., a metal strip). In particular, a viscous material containment system can include a movable seal and a gas delivery device. A method for cooling a roll can include applying a viscous material, such as a coolant, to the roll and containing the viscous material on the roll using the viscous material containment system. In some cases, the viscous material containment system can be used to facilitate removal of the viscous material from the roll and/or the roll processed engineering material.
