本发明叙述在真空下运行的热处理炉。现有的真空炉可分为两大类,即周期作业式的和半连续作业式的真空炉。本发明主要叙述半连续作业式的真空热处理炉,但也适用于作周期作业的真空热处理炉。一、附图的简单说明图一表示真空热处理炉具体装置的透视图,局部剖开,以显示内部结构。图二表示通过图一所示炉子加热室之横断面。图三表示另一种加热室之横断面。
The present invention describes a heat treatment furnace operating under vacuum. The existing vacuum furnace can be divided into two categories, namely, cycle-type and semi-continuous operation of the vacuum furnace. The present invention mainly describes a semi-continuous operation type vacuum heat treatment furnace, but is also applicable to a vacuum heat treatment furnace for periodic operation. Brief Description of the Drawings Figure 1 shows a perspective view of a specific apparatus of a vacuum heat treatment furnace, partially broken away to show the internal structure. Figure 2 shows the cross section through the furnace heating chamber shown in Figure 1. Figure 3 shows a cross-section of another heating chamber.
