Modern blast furnace ironmaking : an introduction

Modern blast furnace ironmaking : an introduction / Maarten Geerdes, Hisko Toxopeus, Cor van der Vliet.

This book describes the principles of the blast furnace process and especially the control of the process. As a starting point, the blast furnace is seen as a simple iron ore smelter, while gradually the physical, chemical and metallurgical background of the blast furnace process is clarified. The b...
