A material to be shaped is reduced and formed by bringing dies with convex forming surfaces, when viewed from the side of the transfer line of the material close to the transfer line from above and below the material in synchronism with each other, while giving the dies a swinging motion in such a manner that the portions of the forming surfaces of the dies, in contact with the material are transferred from the upstream to the downstream side in the direction of the transfer line.

Plate reduction press apparatus and methods

A take-up equipment and a take-up method for a finish rolling mill for dividing a strip into a plurality of coiled products when taking up the strip on the exit side of the finish rolling mill are provided. A plurality of take-up machines (,K,, K,) are disposed at the downstream side of a hot finish rolling mill; a shearing machine (,) is provided on the upstream side of a pinch roll (,) of the take-up machines (,K,) at the uppermost stream end; and a strip passing device (,) is provided between the shearing machine and the pinch roll at the uppermost stream to prevent a strip from rising. The strip passing devices are guiding devices for restricting the height of the rise of the strip or the airflow suction type strip passing devices for drawing in a strip under suction using airflow. The plurality of take-up machines are down coilers or carousel type reels having two winding drums (,).

Hot rolled material take-up equipment and take-up method

Upper and lower drums each with a blade are separated from each other by a hydraulic cylinder until a rotating velocity of the drums are accelerated to a predetermined level. Then, the drums are relatively approached by the cylinder so that gears each fitted to a shaft of the corresponding drum are engaged with each other to keep constant a gap between the blades. The blades are approached to a feed line of a strip to cut off the strip.

Shear

A side dam block disposed along the widthwise end portion of a block mold is supported by springs such that the side dam block is pressed against the casting flat surface of the opposing block mold so that gap between the opposing block molds can be suitably adjusted.

Endless track type continuous casting machine

A dummy nozzle is used for alignment of a pouring nozzle upon insertion of the pouring nozzle in communication with a tundish into a mold cavity of an endless track type moving-block mold continuous casting machine.

Downward force resulting from the block mold and its carrier of the upper mold assembly which move downwardly toward the upstream end of the mold cavity defined by the vertically spaced-apart upper and lower mold assemblies is transmitted to the block mold and its carrier of the upper mold assembly passing the upward path extending upwardly from the downstream end of the mold cavity so that the distortions of the cross-sectional configuration and size of the mold cavity due to the weight of the block molds and their carriers are prevented.

In a mold cavity and/or in horizontal cooling zones, upstream- and downstream-side gears are drivingly coupled to each other through an endless-track-like member to which the tensile force is exerted by a tensioner, so that gaps between the adjacent block molds can be eliminated and therefore intrusion and leakage of a cooling liquid and melt are prevented.

A tundish nozzle is independent from a tundish so that thermal deformations of the tundish are not transmitted to the tundish nozzle.
