Brick Brief IntrodutionMgO-C brick was firstly developed by Japanese in 1970s, and became one popular refractory type which is made from magnesite, graphite as raw material, resin as binder, with high pressure moulding and low temperature treatment. It was introduced to China in1980s and mushroomed. China has became the Mg-C brick producing base due to the superior natual resource (magnesite and graphite resource ) , and attracted the big of world refractory to invest in factories, including RHI, Mayerton and etc. As one compound refractory, it make magnesite good slag erosion risistance and graphite high thermal conductivity and low dilatability mixed together. Thus Mg-C brick has features of high refractoriness, good thermal shock resistance,erosion resistance, and has good performance in I&S industry, including BOF, EAF, LF.
