Cracking in magnesium oxide briquettes

Abstract

The paper considers the geometry of cracks in the volume of briquettes made of a slag-forming material widely used in ferrous metallurgy – magnesium oxide MgO. The authors present the results of measuring the geometry and location of cracks in the volume of briquettes obtained by roller briquetting. The possibility of cracks in the volume of briquettes is a technological feature of roll briquetting. This defect affects the strength of the briquettes, as well as the yield (and productivity) in the process of briquetting on roller briquetting machines. The number and angle of inclination of cracks relative to the direction of briquetting are determined from photographs of the briquette side surface using graphic programs.
