Two High Rolling Machine

GRM Two High Rolling Machine is a compact and versatile metal forming machine designed for reducing thickness, adjusting cross-sectional dimensions, and shaping various metal wires, strips, and profiles.
The machine consists of two horizontally arranged work rolls. During operation, the material passes through the roll gap and undergoes controlled plastic deformation under rolling pressure, achieving the required thickness reduction, width adjustment, or profile forming.
The Two High Rolling Mill can be used as a standalone rolling unit for material development and small-batch production, or integrated into GRM continuous rolling lines according to specific production requirements.

Product Description

Working Principle

A Two High Rolling Mill performs material reduction through the rotation of two opposing work rolls.

The upper and lower rolls rotate in opposite directions, drawing the material into the roll gap and applying compressive force to achieve plastic deformation.

By precisely adjusting the roll gap, the reduction amount and final product dimensions can be controlled.

Key Features

Simple and robust structure with easy operation and maintenance.
Flexible application for wire, strip, and profile rolling processes.
Suitable for single-pass rolling, material trials, and small-batch production.
Can be used as an independent rolling machine or integrated into GRM continuous production lines.

Frequently Asked Questions

1. What is a Two High Rolling Mill used for?

A Two High Rolling Mill is mainly used for wire flattening, strip reduction, and simple profile forming. It is suitable for material trials, small-batch production, and single-pass rolling applications.

2. What is the difference between a Two High Rolling Mill and a Four High Rolling Mill?

A Two High Rolling Mill has a simple structure and is suitable for general rolling and forming processes. A Four High Rolling Mill provides higher rigidity and precision, making it suitable for thin strip rolling and applications with higher accuracy requirements.

3. What materials can be rolled?

The mill can be designed for various metals, including copper, aluminum, stainless steel, and other alloys. The final configuration depends on material properties and product requirements.

4. What is the typical process flow?

A typical process includes:

Pay-off → Guiding → Two High Rolling → Inspection → Take-up

The process can be customized according to production requirements.

5. Can the rolling rolls be customized?

Yes. GRM provides customized roll designs based on product shape, material characteristics, surface requirements, and production capacity.
