摘要:
A material 1 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 1, close to the transfer line from above and below the material 1, 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 1, are transferred from the upstream to the downstream side in the direction of the transfer line.

摘要:
According to an apparatus and a method for manufacturing a hot-rolled steel plate, a roughing process for reducing a thickness of a continuously cast slab is performed to obtain a sheet bar, and a finishing rolling process for rolling the sheet bar is effected to produce a hot-rolled steel plate having a predetermined plate thickness. After cooling down, the hot-rolled steel plate is then wound. A pair of dies 6 each of which has a tapered portion 6b on an input side and a parallel portion 6b on an output side are used in at least part of the roughing process. Further, before performing plate thickness pressing to a material in a plate thickness direction by using the dies 6, at least one of a front end and a rear end of the material is pressed in a widthwise direction to be pre-formed.

Each of a pair of opposing slides which is equipped with a die and is connected through a connecting rod to an eccentric portion of a crankshaft is displaced by a width setting device in the direction of width of a slab so as to set the width of a slab to be forged between the pair of dies. After the setting of the width of a slab to be forged, the crankshaft is rotated to cause each of the slider-pair to reciprocate not only in the direction of width of the slab but also in the direction in parallel with the slab transportation line, whereby a slab is forged.

摘要:
According to one embodiment, a method can include dry etching an interlayer insulating layer provided on a foundation layer by using a mask having a plurality of first openings and a plurality of second openings arranged more closely than the first openings to form simultaneously a first hole reaching the foundation layer under each of the first openings and a second hole reaching the foundation layer under the second openings. The first hole reaches the foundation layer without contacting any other first holes. After starting of the dry etching, a plurality of holes are formed under each of the plurality of second openings, and with the progress of the dry etching, the plurality of holes are connected with each other at least at their upper parts including their open ends to form the second hole having an opening area larger than an opening area of the first hole.
