Finishing Hot Roll Mill One DC Drives Two 75×75×2000mm Billets
HOT ROLL MILL PROCESS EQUIPMENT
1 Raw material spec: 60×60×2000mm
2 Final products spec: Φ8~Φ12mm hot-rolled deformed bar,
3 Hourly output: 8-10t/h
Rolling type and rolling mill configuration
1 Rolling mill layout type adopts semi-continuous.
2 To roll min. Section Φ10mm deformed bar based on 75×75mm
billets, rolling passes is of 15.
3 Adopt “one stand of service ” type to reduce rolling passes gradually.
4 There are total 11 stands of rolling mill in the whole production line,
including Φ400×1 rough rolling mill, Φ300×6 intermediate rolling mill
and Φ300×2×2 finishing rolling mill.
5 Rolling mill drive: Φ400×1 rough rolling mill is AC motor. Φ300×6
intermediate rolling mill is “one AC motor drives six”.
finishing rolling mill is “one DC drives two”
6 The highest rolling speed of final products stands to roll Φ10mm
deformed bar is 8m/s.
1. Rolling mill stand adopts pre-stressed type. This type is high
stiffness and easy to change roller.
2. The rolling mill’s driving applies reducer and the duplex adopt
two-grade reduction united gearbox. This type has following advantage:
low weight, small volume, economical space occupation, low cost and etc.
Gear-shaft material: 42CrMo forged, Wheel gear material ZG35CrMo,
the box is of structural parts.
3. Cooling bed entering adopts free of roller table pneumatic
entering type, which has the advantage of light equipment, simple, low
cost and easy maintenance compared with apron plate type entering
4. End-cropping and multiple-length flying shear adopt
pneumatic clutch frequency controls speed, rotatory type. This type of
flying shear has the advantage of low motor power, simple electric
control and low investment compared with start-stop flying shear.
5. The bundling adopts mechanical pneumatic combined type
automatic machine, and the material for bundling is Φ6.5mm wire rod.
