2 Final products spec: Φ8~Φ20mm hot-rolled deformed bar,
3 Hourly output: 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
4 There are total 11 stands of rolling mill in the whole production
including Φ400×1 rough rolling mill, Φ300×6 intermediate rolling
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
low weight, small volume, economical space occupation, low cost and
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,
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
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

Our company is very professional in designing and producing the
whole production line of hot rolling mill and continuous casting
machine .We aim to offer the products with high quality and
competitive price.The cooling bed is used to cool the bar from the
finishing rolling mill.It is of step-by-step type.
The step-by-step cooling bed is just one kine of our cooling bed.
Our cooling bed type: step-by-step bed, reciprocating type;
notch-bar hot bed; swinging cooling bed; etc.
Electric Control Equipment
Production line of annual output of100,000tons hot rolling deformed bar
1.Outline of process:
The hot billet is directly sent to the hot rolling mechanism by hot
charging roller table through induction heater.The hot charging line is of that cold billet lifted to charging
roller table by the crane and sent to the reheating furnace end.
Then pushed into the reheating furnace by billet pusher and after
the temperature reaches 1150~1250℃,pushed the hot billet out of the
furnace by billet out machine. It enters the two-roller reversible
rough rolling mill of Φ480×1×2 through furnace out roller table and roller table before machine and rolled for 6passes. After
cutting the irregular parts in the head, it enters intermediate
rolling mill of Φ380×2×3 for continuous casting. Set a repeater among the Φ380×2 intermediate rolling mill groups, make the rolling line shift
to the next bay.
The products from Φ380×2×3intermediate rolling mill enter the
finish rolling mill groups of Φ300×1×6 for continuous rolling after
cutting the irregular parts by 2#end-cropping flying shear. In order to improve products' quality and adjust easily,a set of
vertical loop is set among the Φ300 finish rolling mill.
The final products from finish rolling mill cut to multiple length by multiple length flying
shear, and enter the cooling bed entering device through speed-up roller
table and cooling bed entering roller table , and sent to cooling
bed by the cooling bed entering device for cooling. The after-cooling products transferred to cooling bed output roller table from cooling bed exit device and sent to final products cut-to-length flying shear for cut-to-length.
This is our customer's plan, we will according your specific
requirements to design and manufacture the hot rolling mill.
