Product details
Its principle is to use the density of retaining the ball between steel and slag ,whose bulk density generally is 4.2~4.5g/cm3. At the end of steel-making the stopping ball will get to the tap hole to block the inflow of ladle slag. Its shape is approximately spherical.

 1. High slag resistance, high hardness and high temperature resistance.
 2. Can efficiently reduce the content of slag with good temperature stability when tapping.  
 3. Meet the requirement of blocking slag during tapping .
