Four Roller 4 Hi Reversible Cold Rolling Mill For Steel Sheet

Four Roller 4 Hi Reversible Cold Rolling Mill

Automatic Reversible Cold Rolling Mill is different from tandem continuous rolling mill,the metal strip forward or reverse run through rolling mill to reduce strip thickness by number of rolling passes, to-and-fro passes can be up to 5 or 6 until the metal thickness reaches up to finished gauge.

We supply 450, 500, 650, 750 reversible cold rolling mills to Jordan, USA, Nigeria, in domestic market, customer cases of different models for reference.

Characters of Reverse Cold Mill:

1. Metal coil strip materials can be carbon steel, stainless steel, copper, bronze, aluminum, nickle, silver, titanium alloy, etc.
2. The reversible rolling mill can be 2 high, 4 high, 6 high, 8 high, 12 high, 18hi, 20 high
3. Reversible cold rolling requires to and fro rolling in stable, uniform and precise status, the manufacturing precison of rolling mill must be good.
4. Thickness reducing control of reversible mill can be mechanic screw down or hydraulic AGC screw down, required by application, speed and precision of cold rolled metal
5. Two coilers sit each side of the reversible rolling mill while reducing thickness of metal coil strip, to provide coiling tension and wind metal strip up.
6. The drive motor of reversible mill rotate FWD or REV, automatically controlled by motor controller and PLC
7. Rolling Mill model can be 450, 550, 650, 750..., 1150, 1450, valuable metal strip reversing rolling mill model usually is small, steel strip reversible rolling mill popular in over 1m rolling mill.

Features of 4Hi cold mill:

1. suitable for rolling carbon steel, stainless steel, special steel, copper, aluminum strips, etc
2. two work rollers and two backup rollers, drive on work roller or on backup roller
3. press-down type: normal double grades worm gear & screw rod press down or hydraulic AGC
4. Hydrualic work roller bending: can adjust roller convex degree and contact between rollers easily, thus output good flatness of CR strips.
5. Simple structure of less components, easy to be adjusted and maintained.
6. Hydraulic AGC 4Hi mill is high precision
7. DC motors are controlled by 6RA80 series digital DC driver,the mill line is controlled by PLC
