[0002] I I前，一些 S要行业如铝合金、铜合金、镁合金、钛合金等有色金 Ji 型材挤压行业、 配套模具制造行业和锻 tk行业需要对金 阆体材料进行梯度加热，以提高型材挤压的稳定 性，提《产品的品质、特殊性能和成材率。
[0003] 但是常规的燃煤气、煤焦炭、感应线圈加热、电阻加热等方式均很难实现对同体材 料的梯度加热，即使 前存在的感应线圈加热方式来实现金属固体材料的梯度加热，其温 度控制方式极为复杂和不稳定，成本也相当高昂；也有通过改变电流大小的方式来对棒料 分级加热来进行梯度加热，但是这种方式效率很低，控制系统相当复杂，成本也很高，很难 适应大批 *、高标准的产业需求。 发明内容
[0004] 针对上述技术问题，本发明提供了一种简单装置，通过改变永磁转筒轴向磁场强 度分布（磁力线密度 )，即可使固体金 材料在不同的径向截面上存在相同或不相同的温 度。
[0005] 一种针对金属材料的筒形磁式加热装置，包括动力装置、传动装置、永磁转筒、轴 承装置、永磁体，动力装置通过传动狻置与永磁转筒相连接，永磁转筒安装在轴承装置上， 动力装置驱动永磁转筒绕 Γ1身轴线旋转，永磁体安装在永磁转筒的内壁上，永磁体沿轴向 方向上在径向截面上产生的磁场强度存在不同，金 a材料位于永磁转筒的中间 J1与永磁转 筒的内壁上的永磁体不接触、金属材料可以沿轴向移动。传动装置可以是皮带传递、 轮传 动、链轮传动、蜗轮蜗杆传动，可以是刚性或者柔性传递，其作用是带动永磁转筒绕！ ^身轴 线旋转。轴承装置可以是安装在基座上的滚动轴承、滑动轴承或轴瓦，其作用是使永磁转筒 可以绕 身轴线旋转；可以在永磁转筒的巾部安装轴承' ¾置，也可以在永磁转筒的：：侧安 装轴承装置。 传动装 fi "Γ以与永磁转简的巾部相连接 ,也 nj以分别与永磁转筒的 ：侧相连 接，其作用是使永磁转筒平稳旋转。山于永磁转筒二侧是 ¾的，阇体金属材料可以沿轴向移 动使得金属材料得以连续加热，当然也 以使 ^体金 ¾材料在永磁转筒内加热到 -定的温 度后再取出。 由于永磁体沿轴向方向上在径向截面上产生的磁场密度存在不同， H于该磁 场巾的固体金厲材料切割磁力线时，在阁体表面产生的热 也不同，从而造成阀体金 材 料沿轴向方向上在径向截而上的温度不问。
[0006] 优选地：永磁体沿轴向分为多个 K域，各个 K域内的永磁体所产生的磁场强度不 同且沿轴向梯度分布。 山于采用了分 K的形式，在毎个 K域内可以使用与其他 域不同的 永磁体，从而使各个 K域内的磁场强度不相同。
10007] 优选地：各个 !χ:域内永磁体的厚度不同 J1沿轴向梯度分布。 采用相同材料的永磁 体，但是各个 域内永磁体的厚度不同，从而使各个 K域内的磁场强度不扣同。
[0008] 优选地：各个 Κ域内的永磁体分別山不同数量的永磁体部件组成 [1永磁体部件的 数量沿轴 1 梯度分布。釆用相同材料的永磁体，各个 域内的永磁体部件数量都不相同，从 而使各个 Κ域内的磁场强度不相同。
C0009] 优选地：永磁体部件为可拆卸式的。 这样足为了方便更换永磁体以及凋节固体金 屈材料加热所需的时间及温度。
[0010] 优选地：永磁体部件的形状为条形、 Τ形、瓦片形、梯形、矩形、 ¾:形。
toon ] 优选地：动力装 a为可调速的电机。如果加热温度不变的话， ¾用调速装置改变电 机的输出转速来调节固体金^材料加热所需的吋间，如果时间不变的话，采用调速装 S改 变电机的输出转速是为了改变固体金 M材料加热的温度。如果固体金属材料连续通过永磁 转筒，可以通过改变电机的输出转速，使固体金^材料不同的截面上加热的温度不同，也就 是说可以对固体金屈材料 ¾施梯度加热。
[0012] 优选地：永磁转筒材质为金 ¾材料、 ¾强度的 ¾分 材料、塑料和碳纤维材料,永 磁转筒的内腔形状为圆形、方形、菱形、三角形、矩形。
