A permanent magnet may include a Fe.sub.16N.sub.2 phase constitution. In some examples, the permanent magnet may be formed by a technique that includes straining an iron wire or sheet comprising at least one iron crystal in a direction substantially parallel to a <001> crystal axis of the iron crystal; nitridizing the iron wire or sheet to form a nitridized iron wire or sheet; annealing the nitridized iron wire or sheet to form a Fe.sub.16N.sub.2 phase constitution in at least a portion of the nitridized iron wire or sheet; and pressing the nitridized iron wires and sheets to form bulk permanent magnet.

A casting roller or belt for a revolving chill mould of a strip casting system for the manufacture of an aluminium alloy strip and a strip casting system for manufacturing an aluminium alloy strip comprising at least one revolving chill mould with a casting gap. A method for manufacturing an aluminium alloy strip by means of a strip casting system. The object of providing a casting roller or belt or a strip casting system, by means of which, adhesion to the casting roller or belt is avoided during strip casting and a low-segregation and crack-free aluminium alloy strip can be produced, in particular under industrial conditions, is achieved by a specific surface structure, in that the surface of the casting roller or belt has a roughness value Sa of more than 5 μm and an average peak count RPc(0.5 μm) of less than 42 cm.sup.−1.

A control system is a control system of casting and rolling equipment having a twin roll-type continuous casting machine, a rolling mill, and a conveyor. The control system includes a rolling mill control unit that controls the rolling mill by any one of controls including a rolling control and an open control, a conveyor control unit that controls the conveyor by any one of controls including a tension control and a speed control, a first control unit that controls to perform the rolling control and the tension control, a second control unit that controls to perform the open control and the speed control, and a third control unit that controls to resume the tension control and the rolling control.

A machine and process for making a composite battery electrode with a conductive lead cast ribbon extending along and attached to a portion of a carbon fiber material. A lead ribbon may be continuously cast along a longitudinally elongate strip of carbon fiber material. The ribbon may be cast along an edge or edges of a longitudinally elongate strip of carbon fiber material.

A support unit for a roll shaft of a continuous casting guide roll includes a housing having first axial end face, a second axial end face and a through-opening extending from the first axial end face to the second axial end face, a first cover connected to the first axial end face, a first primary isolator arranged radially between the first cover and the roll shaft, and a bearing in the through opening. On a first side of the bearing, a first closed space is partially defined by the bearing, the first cover and the first primary isolator, and the first closed space is pre-filled with a lubricant.

A device for the production of a metallic strip using a rapid solidification technology is provided. The device includes a movable heat sink with an external surface onto which a melt is poured and on which the melt solidifies to produce the strip, and which device includes a rolling device which can be pressed against the external surface of the movable heat sink while the heat sink is in motion.

In this cast strip manufacturing method, in a first step, one end side and another end side in a rotation axis direction of a pair of cooling drums are pressed with a first pressure in a direction in which the cooling drums come close to each other, in a second step, the one end side and the another end side in the rotation axis direction of the cooling drums are pressed with a second pressure, which is higher than the first pressure, in the direction in which the cooling drums come close to each other, and in a third step, pressure control is performed so that a total value of reaction forces on the one end side and the another end side in the rotation axis direction of the cooling drums is set to a predetermined value, and rotation axes of the cooling drums are held in parallel.
