摘要： Disclosed herein are a hot coil of an advanced high strength steel (AHSS), a cold rolling method and a heat treatment apparatus using the same. A heat treatment method of a hot coil of an advanced high strength steel (AHSS)includes performing a hot rolling on a rolled material, cooling and winding the rolled material, forming the hot coil, performing a first cooling on the hot coil to a temperature at which a phase transformation is completed such that a hard phase is generated at an edge portion of the hot coil, heating only the edge portion of the hot coil and increasing a temperature of the edge portion of the hot coil to a tempering temperature, maintaining the tempering temperature for a predetermined time, weakening a strength of the edge portion of the hot coil such that the edge portion of the hot coil which was processed in the performing of the first cooling has a strength similar to that of a central portion of the hot coil and performing a second cooling of the hot coil which was processed in the weakening of the strength of the hot coil edge.

摘要： Provided are a continuous annealing system and a continuous annealing method with which it is possible to achieve an annealing atmosphere having a low dew point which is suitable for annealing a steel strip containing easily oxidizable metals such as Si and Mn at low cost and with stability by preventing easily oxidizable metals such as Si and Mn in steel from being concentrated in a surface portion of a steel strip and the formation of oxides of easily oxidizable metals such as Si and Mn. The continuous annealing system includes a vertical annealing furnace having upper rolls and lower rolls on which a steel strip is wound, a heating zone, and a soaking zone, gas suction ports through which a part of a gas inside the vertical annealing furnace is suctioned, a refiner in which water and oxygen are removed from the gas suctioned through the gas suction ports, and gas delivery ports through which the gas treated in the refiner is returned to the vertical annealing furnace, in which the gas delivery ports are provided at positions where the gas is blown to a steel strip descending in a temperature range of 300°C or higher and 700°C or lower in the vertical annealing furnace.
