Four kinds of common materials of ladle purging plug
Sintered magnesia purging plug : the sintered magnesia material refers to the refractory material with more than 80% MgO content, which belongs to alkaline refractory material. It has the advantages of high refractoriness, strong resistance to alkaline slag erosion, free from Ca and Cao erosion, and no pollution of molten steel. Magnesia chrome purging plug: magnesia chrome material is a refractory material with MgO and Cr2O3 as the main components and periclase and spinel as the main mineral components. Chrome ore is not inert to steelmaking slag and has compatibility with other refractories, so the appearance of magnesia chrome material can improve the thermal shock resistance of magnesia material. High alumina purging plug : high alumina material refers to the refractory material with more than 48% alumina content, which has the characteristics of high cold and hot strength, good wear resistance, heat shock resistance, spalling resistance and good volume stability at high temp...
