Examination of mixer body was performed to detect areas with increased stress zones by the magnitude of coercive force Hc. The paper presents the results on Hc of mixer body. A method to lower stresses on inner surface of mixer body is proposed. 4 References, 2 Tables, 6 Figures.
Keywords: coercimetric testing method, blast-furnace production, mixer body, stress zones
