DEVICE AND METHOD FOR THE PRODUCTION OF A METALLIC STRIP
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.
Control system, control method, control device, and program
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.

Cast strip manufacturing method
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.
Roll line unit and continuous casting apparatus
A roll line unit for a continuous casting apparatus includes a roll mantle having two ends and a non-rotatable shaft including a coolant line. The roll mantle is rotatably mounted on the non-rotatable shaft by means of a first bearing located in a first end region of the roll mantle and a second bearing located in a second end region of the roll mantle. The roll mantle includes at least one coolant channel having at least one fluid inlet that is arranged to be in fluid communication with the coolant line. The roll line unit includes two outer seals located on an axially outward side of each of the first and second bearings, whereby the outer seals and the first and second bearings are located axially inwards of the ends of the roll mantle.
PRODUCTION APPARATUS AND METHOD FOR PREPARING METAL CLAD PLATE IN SHORT PROCESS
A production apparatus for short-process metal composite plate manufacturing, comprising a metal supply device including an uncoiler (1), pinch roll (2), shot blasting machine (3), welding device (4), welding pinch roll (5), induction heating apparatus (6), metal delivery machine (7), two crystallization cooling rolls (8), secondary cooling leveling roll (9), rolling mill pinch roll (10), rolling mill (11), on-line cooling apparatus (12), straightener (13), and at least one of a dividing shear (14) and a recoiling machine (15). Also disclosed is a production method for short-process metal composite plate manufacturing. The apparatus and method combine continuous casting, rolling, and heat-treating means for single material production with continuous and large-scale production of composite plate strips, and production efficiency of composite plates is sharply improved. Single-sided or double-sided composite plate production having different thickness specifications can be performed, the optional range of a base layer or cladding material is wide.
Slinger ring
A slinger, or slinger ring, for a melt spinning apparatus has a cylindrical, mechanically shaped main element that is composed of a refractory metal or a refractory metal-based alloy and has a circumferential surface running in a tangential direction. The circumferential surface is delimited in the axial direction by two end faces. A degree of deformation in the radial direction is greater than the degree of deformation in the axial direction.
Continuous caster roll having a spiral fluted axle
A roll for continuous casting comprises a cylindrical roll rotatably mounted on a fixed axle and said axle comprising a coolant inlet system and a coolant outlet system. A cooling chamber receives a flow of coolant. The coolant chamber is defined by the space between the interior of the cylindrical roll and the axle. Two overlapping spirals are formed onto the axle that creates a helical flow path from the coolant inlet system to the coolant outlet system.
