Rolling Mill

Henan Hongji Mine Machinery Co., Ltd. is a specialized rolling mill manufacturer in China. The company is mainly involved in the production of various models of rolling mills by using advanced technologies.

Application of Rolling Mill:
A metal strip is produced by passing a metal plate/sheet through a pair of parallel cylindrical rolls of the rolling mill. Its thickness is reduced and the metallurgical property is changed.
Rolled metal sheets are extensively used in modern manufacturing industries.

The high external roll forces cause the metal strip to deform permanently. The deformed strip is thinner and longer than the original one.
In accordance with the metallurgical property, the hot or cold rolling method can be used. For example, a steel plate (typically > 1.5mm) is hot rolled; a steel sheet (typically < 0.1mm) and aluminum foil are cold rolled.
Nowadays, rolled steel metal plays an important role in modern manufacturing processes and we can see rolled products everywhere in our daily life.

Foil, the thickness of which is less than 0.2mm, can be used for building insulation, electrical applications and in printing industries for packaging (e.g. to foil containers and wrapping purposes).

If the rolled products have a thickness of 0.2-6mm, they are applicable in the construction industry (e.g. sidings and roofing) and in the transport industry for automotive body panels, airframes and boat hulls.
If rolled aluminum plate is of a thickness higher than 6mm, it can be used for airframes, military vehicles, and as construction components for buildings and bridges.

There is a large demand for aluminum rolled products in Western Europe and 3.44 million tones were consumed there in the year 2000 alone. Since rolling mills were put into use in fifteenth century, there has been continuous integration of new and sophisticated technologies into the manufacturing techniques.

Up to now, the forces can reach 2,000 tones and the speed can be up to 120km/ hour. If the material to be processed is aluminum, the thickness of the rolled aluminum can be to 0.05mm with a tolerance of 5 micrometers (the 0.1% tolerance is in accordance with any "high tech" standard).

For this to be achieved, the mechanical systems, materials, sensors, actuators and control systems have all been upgraded over time.

As a rolling mill manufacturer in China, Henan Hongji makes continual efforts to improve its technologies and upgrade various systems. We strive to provide the best rolling mills as well as cement equipment, fertilizer equipment, mining equipment, crushing equipment for our customers. Our products have received ISO9001:2000 certification and SGS certification.

Presently, we have established a good, cooperative relationship with many users in Vietnam, Bengal, Myanmar, Laos, Peru, Philippines, Iran, India and other countries. We sincerely hope that we can provide our services to more users all over the world.
