Abstract: The instant invention is an improvement on a method of making wire coils comprising the steps of rolling a length of wire having a leading end and a trailing end and displacing the wire in a longitudinal travel direction and coiling the wire into succeeding overlapping loops and depositing same onto an upstream conveyor. The loops are transferred from the upstream conveyor to a downstream conveyor and are deposited from the downstream conveyor onto a centering device to form a coil thereon. The downstream conveyor is driven to move the loops at a generally constant slow transport speed but the upstream conveyor is driven to move the loops at a substantially faster transport speed when loops of a portion of the wire having one of the ends are being deposited on the upstream conveyor. Otherwise the upstream conveyor is driven at the same slow speed as the downstream conveyor so that the loops of the end portion will be spaced more in the travel direction than the other loops of the wire.

Abstract: A cooling conveyor arrangement for rolled wire or wire rod which has left a water cooler has a loop-forming device which deposits the wire in overlapping loops on an air-cooling conveyor. To obtain a shorter cooling path, which is desirable for high-grade steels to reduce the rate of cooling, the loops fall onto a conveyor portion and are carried by a conveyor portion to a coil-forming station where the loops are collected. To obtain a longer cooling path a removable conveyor portion is switched into place so that the loops are carried along a conveyor portion to an opening where they fall onto a conveyor portion. A conveyor portion is swung into alignment with the portion carrying the loops to feed the loops to the coil-forming station.

Abstract: Apparatus for guiding and coiling one or more metallic strands that are continuously advancing along their length from a casting apparatus. A coiling apparatus has an open-top coil-collecting basket with concentric, generally cylindrical inner and outer walls. A rotating cone is disposed over the inner wall. At least one boom and a set of opposed rolls and associated fairing assemblies mounted on the boom guide the strand from the casting apparatus to the coiling apparatus.

The boom exit end mounts a straightener that includes a pair of hydraulically-actuated slide bars that are orthogonal to each other and to the strand. The slide bars produce a cyclic deflection of the strand about the center of the cone to form a uniform, non-tangled coil.

Abstract: Cooling by a gas coolant of carbon steel wire coils which have been heated to above the austenizing temperature of the wire is controlled to rapidly quench cool the wire coils to within a selected critical range of temperatures which results in a desired fine pearlitic crystalline structure of the steel wire, by controlling the impingement pattern and velocity of the coolant gas on the wire.

The distance between the discharge slots of each box and the wire coils may be selectively adjusted by raising or lowering individual ones of the plenum boxes relative to the level of the wire coils on the conveyor device.
