1. Description of goods
2 Hi Cold Rolling Mill controlled by hydraulic roller bending
device with One stand and two frames
2. Introduction:
The 2-Hi cold rolling mill, one of metal coil cold rolling mill, is
made from good quality raw material. At the same time, we are
upgrading with the latest technological equipments when producing
this cold rolling mill. Due to different numbers of rollers, the
metal coil cold rolling mill is divided into 2 Hi, 4 Hi, 6 Hi, and
12 Hi AGC.
3. Features:
1. The 2-Hi cold rolling mill is a kind of portable type.
2. One stand and two frames are made from fabricated steel plates.
3. The number 2 Rolls on this cold rolling mill are made of chilled
material.
4. It is equipped with heavy duty reduction gear.
5. The screw down system is manual.
6. We adopt one number C.I. casting flywheels.
