Spheroidal Graphite Iron (Pearlitic) Rolls
Spheroidal Graphite Iron Pearlitic Rolls are distinguished by their nodular graphite structure, which provides a significant advantage over traditional Cast Iron Rolls that contain flake graphite. This nodular form enhances strength and improves resistance to thermal and mechanical stress, making these rolls ideal for high-temperature and heavy-duty applications.
The microstructure of these rolls consists of nodular graphite and various carbides embedded within a pearlitic matrix. This composition ensures excellent strength, stable hardness across the working layer, and strong anti-accident properties, even under challenging operating conditions. Engineered for consistent performance and longer service life, Vimco’s SGI Pearlitic Rolls are the ideal choice for mills seeking dependable quality and efficiency. When precision and toughness matter, choose Vimco Rolls – the best Spheroidal Graphite Iron (Pearlitic) Rolls manufacturer in India
