Introduction to Refractories

 

INTRODUCTION TO REFRACTORIES - 

Live On line.   Eight 3-hour lectures

COURSE DESCRIPTION: 

This course addresses most of the significant topics in the field of refractories, both theoretically and experimentally.  The lectures follow the natural evolution of refractories from their mineral and synthetic origins, to their chemical, mineralogical, and microstructural constitution, and their application, installation and degradation in service.  The sesions are also designed to give the participants knowledge of common refractory testing techniques.  

WHO SHOULD ATTEND:

Engineers, managers, contractors, purchasing agents, furnace operators, maintenance supervisors, and technicians who are involved in the manufacturing, marketing, research and development, or consumption of refractory materials will find this course beneficial. Refractory installers and maintenance personnel may particularly benefit from better installation and maintenance techniques. A high level technical or engineering background is not essential to take this course, although technical professionals will find the subject matter informative and useful.

COURSE OBJECTIVES:

The objectives of this course are to introduce the participants to the ceramic engineering fundamentals of all of the classes of refractories, their constitution, their application, and some of their degradation and failure processes. 

INSTRUCTOR:

Dr. Joseph Homeny is Technical Director of the Edward Orton Jr. Ceramic Foundation, Columbus, Ohio. He holds a Ph.D. degree in Ceramic Engineering from the Pennsylvania State University and M.S. and B.S. degrees from Rutgers University. He has industrial refractories experience in the research laboratories of the J.E. Baker Co. and North American Refractories Co. Prior to joining Orton in 1992 he taught refractories as a professor in the Ceramic Engineering Department of the University of Illinois. Dr. Homeny is active in the refractories and advanced ceramic committees of ASTM.
