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.Features 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 .SpecificationFe%Al2O3％Cold crushing strength Refractorinessspecific gravity g/cm3Moisture80-8515-20≥60mpa≥1750℃3.8-4.5≤0.1％Note: The chemical composition can be adjusted as per your requirements.Our serviceOur company produce a wide range of slag stopper, cone slag stopper, stopping rod with different specifications and types, mainly include magnesia polyhedron stopper, cone stopping plug,etc. Also they keep a competitive price in the line of market. They have such advantages as great performance on slag(block more than 95% slag), high temperature resistance(more than 1780℃), erosion resistance, easy operation and can be chosen within 4.0-4.5(g/cm3) product density according to the slag viscosity.Images
