TECHNICAL RESEARCH ON REDUCED EXPANSION OF PELLETS OF BAOTOU STEEL BY ADDING BENTONITE

摘要

This text which based on the existing conditions of raw material and technological of pellet production of Baotou Steel research on reduced expansion of pellets. The result proves that raise the proportion of bentonite is notable impact on reduce expansion of pellets, meanwhile the basicity of pellets could not change. Because of the difference of proportion of locally produced iron ore in pellet iron materials, the bentonite adding in pellets is different.
