Therefore, what determines steel production and cost are refractory products. However, magnesia carbon brick as a kind of high-quality refractory materials, with its excellent alkaline slag erosion resistance and good thermal shock resistance, is widely used in electric furnace, converter, refining furnace , ladle lining, and other important parts. This design is for yearly producing 35000 tons of converter magnesia carbon brick MT - 14 b and MT - 18 c production workshop design, fused magnesia and flake graphite as the main raw materials, phenolic resin as binder, metallic Al powder as antioxidants. This design introduces the development history, classification, composition, performance, damage mechanism and the future development of magnesia carbon brick. Then, it describes in detail the technological process of the product design and equipment selection, and it also expounds the process flow arrangement and argument. Moreover, for the quantity of the materials needed by stages and mechanical equipment, material balance calculation and equipment selection calculation are conducted. The main characteristics of this design are the process flow, reasonable layout and small environment pollution. In addition, its characteristics also include recycling and reuse of waste bricks body to reduce cost, a high degree of automation , improving the safety protection measures and so on.Key words: Magnesia carbon, process design, workshop design1 绪论1.1 镁碳砖的发展历史及其应用1.1.1镁碳砖的发展历史MgO-C砖是20世
