Chapter II Production Capacity

Calculate original parameters:

*4-section acid tank (11.75 × 4=47m);

*Maximum linear speed of the unit 100m/min

*Minimum chemical reaction time: 25.8 seconds

*The threading speed of the unit is 30 meters/minute

*Average specification: 2.25 × 1000 Average coil weight 16 tons (outer diameter 1800mm)

*Annual production capacity: 300000 tons/year

Annual production working hours

1. Calendar time: 365 × 24 hours/day=8760 hours/year

2. Non-production time of the unit

Annual maintenance downtime

10 days × 24 hours/day × 1=240 hours/year

Scheduled maintenance shutdown

23 times/year × 8 hours/time=184 hours/year

3. Production utilization time

A-B=8336 hours/year

4. Production efficiency η= 0.8

Including: equipment failure shutdown, production accident handling such as arch belt, roll change, production plan change, etc.

Estimated net production time is 8336 × 0.8=6668.8 ≈ 6670 hours.
