金属管材的快速均匀加热方法
摘要：
金属管材的快速均匀加热方法，它涉及一种金属管材的加热方法，具体涉及一种金属管材的快速均匀加热方法，以解决现有金属管材感应加热方式存在金属管材周向温度和轴向温度分布不均匀，以及影响金属管材成形的问题，加热方法的具体步骤为：步骤一、将待加热的金属管材放置到感应加热线圈中；步骤二、感应加热线圈通电，金属管材开始加热；步骤三、金属管材加热中，金属管材和感应加热线圈作相对运动；步骤四、待金属管材的受热温度达到300℃~1100℃后，停止加热，并将金属管材从感应加热线圈中移出。本发明用于金属管材的加热。
摘要（英）：

The invention relates to a heating method for a metal tube, in particular to a rapid uniform heating method for the metal tube. The heating method comprises the steps that firstly, the metal tube to be heated is placed into an induction heating coil; secondly, the induction heating coil is energized, and the metal tube is heated; thirdly, the metal tube and the induction heating coil are moved relatively when the metal tube is heated; and fourthly, the heating is stopped when the heated temperature of the metal tube reaches 300 DEG C to 1100 DEG C, and the metal tube is taken out of the induction heating coil. The rapid uniform heating method is applicable to heating metal tubes and capable of solving the problems that the circumference temperature and the axial temperature of metal tubes are unevenly distributed and the forming of the metal tubes are influenced by the uneven distributed temperatures in prior induction heating methods of the metal tubes.
