The silicon dioxide content in the light burned magnesium ball should be controlled at a certain percentage. If the silicon content exceeds the standard, the plasticity and toughness of the steel will be significantly reduced. Silicon can reduce the density, thermal conductivity and electrical conductivity of steel. It can promote ferrite grain coarsening and reduce coercivity. Light burned magnesium ball supply, silicon can promote columnar crystal growth in cast steel, reduce plasticity. Silicon can reduce the weldability of steel. Because of the junction with oxygen
