Introduction

Over the past twenty-five years there have been many changes in the technology of steelmaking, so that mills today are in many instances radically different from those of the 1970's. The 1970's is the beginning of the period of the refocusing of the steel minimill industry. By refocusing, expected and unexpected changes ensued. This book will demonstrate how every facet and every phase of ironmaking and steelmaking were revolutionized: from the preparation of raw materials to the delivery of finished products.
