Cold Rolling Mills
 |
| we are the manufacturer who engegd in produce various models of Cold Rolling Mills. Don't hesitate to contact with us if any questions you have. |

| Application of Cold Rolling Mill: |
HONGJI GROUP is a manufacturer and supplier of Cold Rolling Mill Equipment for rolling ferrous and non-ferrous products as per design & specification of the customer.
Rolled sheet metal is an important material in modern manufacturing, rolled products are found everywhere in our daily lives.
We design and engineer cold rolling mills comprise of mill stand, gear boxes, drive systems, coil loading device with uncoilers, coilers, entry & exit tables, measuring and control devices, coil removal system, coolant supply systems, centralized lubrication systems, hydraulic system and complete electrical equipment.
The mills can be fitted with AGC systems, Zonal coolant control systems, Flatness measurement & control systems, Hydraulic Roll Gap adjustment system etc. to ensure close thickness tolerance, flatness and surface finish.
The mills are custom designed depending on the material being rolled, thickness and width requirements, production capacity, mode of operation (reversing or non-reversing) and other inputs.
Our range of Cold Rolling Mills include:
- Cold Rolling Mills
- Cup Down Mills
- Skin Pass/ Temper Pass Mills:
These mills are designed for making sheet / strip of medium hardness or to give finish pass. The Rolls are made of alloy steel having very high hardness (generally 65 HRC +).
We also design and manufacture HI Cold Reduction Mills for Sheet & Strip |

The high external roll forces cause a permanent plastic deformation of the strip, decreasing it¡¯s thickness and producing a corresponding increase in length. The strip may be either hot or cold rolled. For example steel plate (typically > 1.5mm) is hot rolled and steel sheet (typically < 0.1mm) or aluminium foil are cold rolled.
Rolled sheet metal is an important material in modern manufacturing, rolled products are found everywhere in our daily lives. Consider rolled aluminium products:
- Foil less than 0.2mm thick is used in packaging such as foil containers and wrapping, in electrical applications, building insulation and in printing industries.
- 0.2mm to 6mm thick has a wide variety of uses in construction industries such as sidings and roofing. Sheets also used in transport for automotive body panels, airframes and boat hulls.
- Plate over 6mm thick airframes, military vehicles, construction components for buildings and bridges.

In the year 2000 alone, 3.44 million tonnes of aluminium rolled products were consumed in western Europe. Rolling mills have been in use since the fifteenth century, however increasing performance demands have recently lead to greater sophistication in rolling mill technology.
Forces can be of the order of 2,000 tonnes, strip speeds up to 120 km/hour and (in the aluminium industry) thickness as low at 0.05mm and tolerances of 5 micrometers. (This represents a tolerance of 0.1% which is ¡°high tech¡± by any standard.) The mechanical systems, materials, sensors, actuators and control systems required to achieve this have undergone substantial improvement over time. |
