国产的 RJJ—36—6井式回火电炉,由于它能强制循环,使炉温均匀,是一台很好的回火电炉。鉴于铝合金淬火温度要求范围狭窄。温度高,合金元素的溶解速度就越快和越完全,同时合金元素在合金中的分布也越均匀,这就使淬火后的成品或半成品具有更高的机械性 Domestic RJJ-36-6 pit type tempering furnace, because it can be forced to cycle, so that uniform temperature, is a good tempering furnace. In view of the narrow range of aluminum alloy quenching temperature requirements. The higher the temperature, the faster and more complete the dissolution of the alloying elements, and the more uniform the alloying elements are in the alloy, which results in a higher mechanical or mechanical properties of the quenched finished or semi-finished product
