Clinker particles in the kiln are formed under the action of liquid phase (some data call melt), and the liquid phase forms capillary bridge outside the crystal. The liquid phase capillary bridge plays two roles in light burning of magnesium powder: one is to bind the particles together, the other is to act as an intermediate medium to make CaO and C2S diffuse in the molten state to generate C3S. The strength of the particles depends on the strength of the capillary bridge

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

Light burned magnesia is an alkaline refractory raw material. The raw material for producing magnesia is magnesium carbonate, commonly known as magnesite. Magnesia can be roughly divided into heavy burned magnesia, medium grade magnesia, high-purity magnesia, fused magnesia, large crystal fused magnesia. The main component of these magnesia is Mgo magnesia. Our factory recommends that the refractory coating should choose over 90% of heavy burned magnesia or 95% of heavy burned magnesia

Light burned magnesia powder also contains three substances (as the saying goes): undercooked products, overburned products and active magnesium oxide 1: The so-called undercooked products are some magnesium carbonate that does not form magnesium oxide. (The control of the setting speed of magnesite products mainly depends on the number of undercooked products.) If there are more undercooked products, the burning vector will be high, and the setting speed of the produced magnesite products will be particularly fast, which will lead to the bursting of magnesite products,
