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

Strictly speaking, magnesia beyond its shelf life will generally affect the activity of the calcined magnesia itself. However, if the stock is large, discard it and worry about waste. Now we tell you that you can check whether it can be used again from the following aspects. The production of desulfurized magnesium oxide shall be initially inspected. Normally, magnesium oxide should be white powder. If oxidized

Light burned magnesium ball refractories refer to inorganic non-metallic materials with refractoriness over 1580 ℃. The refractoriness refers to the centigrade temperature at which the refractory cone specimen can resist high temperature without softening and melting down under no load. Refractory materials have a long history. Refractory materials combined with high temperature technology appeared in the middle of the Bronze Age; During the Eastern Han Dynasty in China, clay fire resistance appeared

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

What is the relationship between the operating temperature of the calcined magnesia component and the insulation resistance? For almost all insulating materials, the higher the temperature is, the smaller the insulation resistance value will be. The insulation performance of magnesium oxide powder conforms to this rule. What effect does the minimum insulation resistance value have on the overall design? During product design, we should make clear the minimum value of insulation resistance of components at the highest operating temperature, and whether it can meet
