Manufacturing Process
The steel roughing mill stand is used to reduce the thickness of the steel while extending the overall length. The rack of the rough rolling mill is an important part of the steel frame. The rack is equipped with a roll chock and a roll adjustment device. The rolling mill stand must have sufficient strength and rigidity to withstand the rolling force.
Melting & Casting & Rolling Process
Steel Iron metal
Scrap iron and steel are usually used as raw materials for production lines.
Melting furnace
Steel and iron metals and other scrap metal materials are mixed and melted into molten steel at high temperatures to form components in the required proportions.
Continuous casting machine
The molten steel made by the steelmaking furnace is cast by the continuous casting machine to obtain the continuous casting billet.
Rolling mill
The rolling mill is mainly composed of several sets of rolls. The rolls are a pair of rolls that rotate in opposite directions. A gap or hole of a certain shape is formed between the two rolls. The steel billet passes through the roll to become a steel of a certain shape.
Final product
After hot rolling, water is penetrated immediately, the surface is controlled to cool, and then the core residual heat is used to complete the tempering treatment of the finished steel bar.
Product Details
We can manufacture and provide complete rolling mills for rolling rebar/wire rod/structural steel (such as angle steel, I-beam, channel steel, steel plate, etc.).

Frequently Asked Questions
Q
What is the main function of the steel roughing mill stand?
The steel roughing mill stand is designed to reduce the thickness of the steel while extending its overall length. It serves as an essential part of the steel frame structure, engineered with sufficient strength and stiffness to withstand rolling forces.
Q
What materials are used as raw materials in the production line?
Scrap iron and steel metals are typically used as the primary raw materials. They are mixed and melted under high temperatures inside the melting furnace to form the required steel components.
Q
What are the core technical specifications for the φ550, φ450, and φ350 models?
The models differ in diameter/length of barrel, roller neck sizes, and maximum rolling force. They all feature a ±3mm rollaxial adjustment capability and utilize a hydraulic roll gap adjustment method for precision control.
Q
What special design features make this mill stand durable?
It features high strength and stiffness suitable for enduring heavy loads. The complete stand is stress-relieved and fully machined, offering quick roll changes to minimize downtime along with long bearing life and fully automatic operation.
Q
Do you provide custom design and engineering layout support?
Yes. We offer design, manufacturing, installation, and commissioning with a "turn-key" service. We can provide foundation layout and arrangement diagrams, as well as customize or revamp other non-standard equipment based on user requests.
