Steel rolling mills have played a pivotal role in the industrialization of the world. Rolling steel was invented in the late 17th century in England and quickly became the preferred method for shaping and forming metal. The first rolling mills were small and crude, but they laid the foundation for the massive, automated mills we see today.
