Purpose-directed hot zone and cooling-gas stream design of vacuum furnaces

The heat-treatment processes of various components and loads have most different requirements reg. uniform components cooling as well as for high quenching speed. Rectangular hot zone design with large scale gas through-streaming is still and again for many standards and also for special loads recommendable. In this way gas through-streaming, which corresponds to load plain, can even take place from various directions and with flow reversal. Round hot zones design with nozzle cooling can offer, however, advantages through higher cooling capacity for hardening processes of large size components.
