Product introduction

The rough rolling mill (also called billets rolling mill) is mainly used for reciprocating the rolling of the steel billet heated by the heating furnace, and rolling it into a certain size of the intermediate billet for the continuous rolling mill. The rough rolling mill stand is an important part of the working stand. The rolling mill stand bears the rolling force and must have sufficient strength and rigidity. Luoyang Judian Metal Thermal Processing Equipment Co., Ltd. is mainly engaged in the production of steel rolling equipment. ferrous metal rolling equipment such as profile rolling mills, small rolling mills, rolling machinery, waste steel bar transformation equipment, etc.

Product Features

Multiple Stands

The roughing rolling mill typically consists of several stands, each containing two rolls. The metal passes through each stand, reducing its thickness progressively. We offer different types of rough rolling mill stands.

Large Size

Rough rolling mills are usually large machines, capable of handling metal bars or sheets of considerable size and weight. The diameter of the roll is Ø200~Ø650. However, thanks to the advanced design, it is very convenient to maintain or replace the roll.

High Speed

Roughing rolling mills operate at high speeds, typically 30 to 50 meters per second, to ensure efficient reduction of the metal thickness.

Heavy-duty Construction

Roughing rolling mills are built to withstand the high stresses and strains involved in the hot rolling process. They are typically made of high-grade steel and other durable materials.


Judian roughing rolling mills are highly automated, with computerized controls that allow precise adjustment of the rolls and other parameters to ensure consistent quality of the final product.

Long Service Life

The entire stand of roughing rolling mill is made of steel castings, stress-relieved, and fully machined. The roller has a long life and can roll about 3,000-4,000 tons.
