摘要： PURPOSE:To provide a uniform fine transformed structure to a wire rod of a carbon steel bar by heating the rod to a specified temp., rapidly cooling it to a temp. just above the transformation point while applying a pressure with dies, and carrying out transformation. CONSTITUTION:A wire rod of a carbon steel bar is heated to the Ac3 transformation point or above and held under pressure with dies which move continuously in synchronism with a wire rod feeding speed. At the same time, the rod is cooled to the transformation starting temp. and transformed by relieving the pressure. For example, the temp. of dies 1, 1' is adjusted to about 500-550 deg.C, and about 100kg/ mm. pressure is applied to wire rod M of a steel bar with pressing rolls 2, 2' at a predetermined speed. After supercooling rod M to the temp., dies 1, 1' are removed. Thus, a uniform fine pearlite structure is obtd.

摘要： PURPOSE:To make possible the production of the wire material free from variations in the strength in the coils and between the coils by air-cooling the coils of hot rolled steel wire material from above while transferring the same at the specific angle and spacing by means of conveyors. CONSTITUTION:The hot rolled steel wire material W is wound to spiral coils C by a loop former 2 and is held on a moving and placement conveyor 5 in such a manner that the angle alpha that the coil loop face assumes to the conveying direction H (nearly horizontal direction) of the coils C becomes 30-60 deg. and that the pitch P between the loops becomes more than about 4 times the wire diameter d of the wire material W. While the conveyor 5 is being moved, the air A being a cooling medium is fed from below to above to cool the wire material coils C. By cooling, the structure of the wire material after the transformation substantially becomes fine pearlite structure. The wire material coils assume an even strength in any portion; in addition, there are no variations in the strength between the respective wire material coils, thus the wire material of an even strength is obtainable.

摘要： PURPOSE:To perform titled heat treatment and produce a wire rod of high hardness and high strength by feeding a heated metallic wire rod into the gas of the corresponding hole grooves of a grooved roll and segmental dies and pressing the dies while revolving the roll simultaneously. CONSTITUTION:A grooved roll 1 is revolved in an arrow direction at the speed synchronized with the feed speed of a metallic wire rod 7, and the heated wire rod 7 is inserted into the hole grooves 2, 3 of the roll 1 and segmental dies 4, 4' at the point X. High pressure is loaded upon the wire rod 6 by pressing the dies 4, 4' in the axial center direction of the roll 1, and is released by detaching the dies from the grooves 2, 3 at the point Y to remove pressure. The wire rod 7 loaded with high pressure is quickly cooled by the dies 4, 4' preheated to around a pearlite transformation temp., but since it is loaded with the high pressure, its pearlite transformation is retarded. Thence, at the point of the time when the high pressure is released, the core part and surface layer part of the wire rod 7 cause the transformation almast simutaneously, thereby forming the fine pearlite structure.
