Rotary type solid solution heat treatment furnace, mainly used for all kinds ofstainless steel pipe of continuous solid solution heat treatment. The devicehas the characteristics of mass production, stable quality, low energy consumption, high degree of automation, convenient operation, safety, etc..Through the rotating device drives, the required solution treatment of thestainless steel pipe in and out of heating furnace, steel pipe itself is always in the rotation state, thus solving the stainless steel pipe in the solid solutionexists uneven heating, easy to produce deformation problem.
