1.2   Equipment Functional Requirement

1.2         
  1.2.1        Process requirement: meet the Al. wheel T6 heat treatment process requests
  1.2.2        solution furnace:
50min +230min =280min(200min~360min)
50min heating + 230min holding= 280min inside furnace (200min ~360min, adjustable )
  1.2.3        Aging Furnace
30min heating + 170min holding = 200min inside furnace (120min ~ 270min adjustable )
  1.2.4        production capacity of each line
1.3 
Production rate: 1,000,000pcs/year,(24h/day, 300workding days/year, specific wheel size: 17×10 inch, φ476mm)
Hourly production rate: 1000000÷300÷24=138.89pcs /h
Each cycle loaded wheels number:
one layer loaded with 5 wheels, 3 layers,
5×3=15pcs
Hourly working cycles: 138.89÷15 =9.266 cycle /h
Cycle time : 60÷9.266=6.48min
