Pearlitic and Pearlitic / Sorbitic Nodular Iron Rolls

Pearlitic and Pearlitic / Sorbitic Nodular Iron are nodular grades alloyed with Cr, Ni, and Mo with Ni ranging between 1.*0 % in the softer grades and 4 % in the harder grades. The right balance of Si and Cr will help to develop the adequate hardness level.

The rolls can be cast static or spun cast depending of the size of the working layer and the mill conditions.

Application

Roughing stands of bar, wire rod and medium section mills.
Intermediate stands of bar mills.
Sleeves of Universal stands.

Compared to pearlitic irons, acicular irons show higher strength, toughness and wear resistance.

The rolls can be cast static or spun cast depending of the size of the working layer and the mill conditions.

Application

• Intermediate and finishing stands of bar, wire rod and medium section mills.
• Forming, sizing, reducing and straightening rolls for pipe and tube mills.
• Sleeves for Universal finishing stands (Horizontal & Vertical).

• 2 Units **0 mm

Plus a complete set of chills, chillers and moulding tackle to cast all kind of rolls including big section rolls with the barrel shaped with grooves and collars in as-cast condition.

*-HEAT TREATMENT

During the manufacturing process of rolls, many materials need to pass one or more heat treatment to further achieve the most appropriate mechanical properties and good microstructure. The resistance furnace of TS ROLL can achieve multi-point precise temperature control to ensure uniformity of the furnace temperature. Between different furnaces, we use a unified computer control to achieve the furnace heating and cooling consistency in order to ensure the rolls from different furnaces with same microstructure and performance.
