內容簡介

Corundum-spinel based purging plugs are widely utilized in refining steel ladles, however, they were usually fired at high temperature, which required high energy consumption. More importantly, their dense structure and higher strength easily resulted in fracture or thermal spalling, which greatly limited their improvement of service life. Recently, unfired purging plug have been tried out by some manufacturers, unfortunately, there are some shortcomings including low strength at medium temperatu...
