  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 temperat

  According to production process, fire clay brick is divided into machine made brick and handmade brick. According to structures, fire clay brick is divided into solid brick and hollow brick, and hollow brick can be divided into load-bearing brick and nonbearing brick. Fire clay brick is made at different shapes according to different using requirements. Advantages of fire clay brick： 1. Fire clay brick is environmentally friendly and belongs to resource recycling bricks, so we can rest assured use fire clay brick. Fire clay bricks won’t be harmful to our health. 2.Fire clay brick has advantages of fireproof and heat insulation. Used clay brick can be used as concrete so that to save a lot of resources. 3.The price of fire clay brick is not as expensive as that of other fire bricks. Light weight brick is more expensive than fire clay brick. Besides, fire clay brick is very cheap and very durable 4. Fire clay brick has good moisture-proof function, it also has the a
