一种高效节能全纤维台车式真空退火炉A high-efficiency and energy-saving full-fiber trolley-type vacuum annealing furnace

技术领域technical field

背景技术Background technique

退火是变压器铁芯加工过程中的一个常见工艺,为了达到某种特性,如消除硅钢的应力,变压器铁芯需要经过加热后,保持一段时间,然后缓慢降温以获得该种性能。退火炉是退火加工中不可或缺的加工设备,现有的退火炉均由退火炉炉体和内胆组成,且炉体和内胆之间设有间隙,这样炉体内的炉胆被多次加热之后就会发生严重的变形,导致炉体内的空间变小,影响进料台车的进出,易发生进料台车的刮蹭,同时炉体内炉胆的加热变形往往会导致炉胆壁断裂,炉胆壁上安装的加热元件也会出现脱落;现有的退火炉的炉门是采用侧开机械式的锁扣装置进行封闭的,这样在炉门关闭以后炉门与炉体之间存在较大的缝隙,这样在退火炉加热的过程中将有大量的热量散失掉,造成资源浪费。Annealing is a common process in the process of transformer core processing. In order to achieve certain characteristics, such as eliminating the stress of silicon steel, the transformer core needs to be heated for a period of time, and then slowly cooled to obtain this performance. The annealing furnace is an indispensable processing equipment in the annealing process. The existing annealing furnace is composed of an annealing furnace body and an inner container, and there is a gap between the furnace body and the inner container, so that the furnace body in the furnace is repeatedly Severe deformation will occur after heating, resulting in a smaller space in the furnace body, which affects the entry and exit of the feeding trolley, and is prone to scratches by the feeding trolley. At the same time, the heating deformation of the furnace inside the furnace often leads to the breakage of the furnace wall , the heating element installed on the furnace wall will also fall off; the furnace door of the existing annealing furnace is closed by a side-opening mechanical lock device, so that there is a gap between the furnace door and the furnace body after the furnace door is closed. If the gap is large, a large amount of heat will be lost during the heating process of the annealing furnace, resulting in waste of resources.
