Abstract
Magnesia-carbon bricks plays an important role in refractory material, and used in various applications,such as steel ladles、electric furnace、convertor 、bakie、steel mouth, high-power electric furnace hot parts of the wall,and the furnace,refining furnace lining.Magnesia and graphite is main raw materials of Magnesia-carbon bricks. Magnesia- carbon bricks possesses excellent anti-erosion of slag,slag permeability,thermal shock stability.The main products designed for the ladle Magnesia-carbon bricks,brand is MT14B, MT18C.The design study magnesia-carbon brick through the development and nature of production processes,a detailed description of this process of product design,equipment selection and layout.Calculated to select the necessary equipment and materials in volume.The main features of this design is a rational layout,low cost production,process smooth.
Keywords: Steel ladles;Magnesia-carbon bricks; Production technology; Calculation of equilibrium
