另外，本发明的热轧钢材的方法用于制造基于氮化物的包装钢具有从400的碳含量1200ppm范围内，轧制由扁钢产品，退火，特别是在连续退火冷冷却钢产品 为了增加的量引入或未结合的氮成对应于由特征的轧钢产品的该序列的人决定退火的扁钢产品在上述100ppm的浓度的量，和所述非粘结氮对应于超过100ppm的浓度 含氮气体引入炉中，并将退火朝上表面扁条，扁条被部分在再结晶退火后立即的至少100K / s的冷却速度冷却。 使用该方法，冷轧扁平产品可以为了包装目的而制造，其抗拉强度为至少650MPa，特别是700-850MPa。

The present invention is hot rolled as steel to a method for manufacturing a nitride-based packaging steel having a carbon content of from 400 to 1200ppm range from, rolling cooling the steel product by flat bars products, annealing, especially the cold in a continuous annealing in order to increase the amount of the introduction or unbound nitrogen into the flat bars products corresponding to the sequential recrystallization annealing of the rolled steel product made of a feature, and the non-bonded nitrogen in the above 100ppm concentration in an amount corresponding to more than 100ppm concentration nitrogen-containing gas is introduced into the furnace and the annealing facing up the surface flat bars, flat bars is part is cooled at a cooling rate of at least 100K / s immediately after the recrystallization annealing. Using this method, while having a tensile strength of the cold-rolled flat bars the product is more than 650MPa, especially 700 to 850MPa can be prepared by packaging purposes.
