This roller hearth solution and aging production line is supplied for heat treatment large scale aluminum alloy. it is supplied by natural gas as energy source, combined with electrical control system, working process of the complete line is automatically regulated. Mechanical movement has interlock function with each other, inner atmosphere is stirred by circulating fan, temperature uniformity can achieve as ≤±3℃.
2. Designing Principle and Working Process Requirement
Temperature in solution furnace: 548±5℃; Temperature in aging furnace: 168±5℃.
Quenching Transfer time in solution furnace: ≤15S. （It starts timing when the door totally open）
After aging process, aluminum castings will be cooled by force air , and castings temperature will be cooled to 60-80℃.
Working Cycle: ～45min/ stacker（ adjustable）
Stackersize: 1800×1600×1600㎜, load capacity per basket: ～200 pcs.
