Title: Method for upward-casting metallic wire, bar and pipe and casting apparatus
Inventor: KOIVISTO MARKKU
IPC: B22D11/124
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To simply and easily control a process at a low cost by casting a non-ferrous metallic wire, bar or pipe to be cast in the direction having a specific angle to the vertical axis of a furnace and executing directly secondary cooling to the cast material by water spouting. SOLUTION: The casting is executed upward at 20-85 deg. angle to the vertical axis. A primary cooling device 4 and a casting nozzle 3 partially inserted into the device are dipped into the molten metal contained in the furnace at about 45 deg.C. Since the molten metal is solidified in the casting nozzle, the formed wire and bar 5 can be drawn out on a bending drum 7 through a transferring drum 6. The secondary cooling part of the cast product contains a water spouting hole 8 and a chute 9, and the chute 9 recovers the spouted water from the spouting hole by positioning below the cast product and the bending drum. It is desirable to enclose the product with protecting gas in the range between the primary cooling zone and the secondary cooling zone in the casting nozzle.

Abstract: PROBLEM TO BE SOLVED: To provide constant winding force against changes of various conditions by arranging a loading means applying winding resistance to the paper at the front stage of a paper winding section winding the exposed paper into a roll shape, and making the magnitude of the winding resistance of the loading means variable. SOLUTION: The first torque generating device 65 invariably applies winding resistance to the rotation of a feed roller 37, and the second torque generating device 66 applies winding resistance to the rotation of the feed roller 37 when the first electromagnetic clutch 67 is turned on. The first electromagnetic clutch 67 is operated by the control signal from a controller. The increase/decrease switching characteristic of the winding resistance is changed depending on the margin torque of a winding motor. Increase/decrease switching directions are determined against various conditions, and increase/decrease characteristics are set to obtain fixed winding force and secure a stopping system based on the inertia of a wound roll. The paper can be wound with nearly fixed winding force.
