Title Environmental stresses and strains in an extreme situation - The repair of electrometallurgy furnaces
Bibliographic information 1993, Vol.65, No.4, p.253-258. Illus. 24 ref.
Abstract During the replacement of an electrode element from a 20MW continuous casting furnace, excessive temperatures and CO levels were found. The wet bulb globe temperature in the furnace centre was 55░C. In the furnace periphery the WBGT measured 34░C. These temperatures did not change significantly during the 6h of replacement work. The mean CO levels of 110 to 145ppm in the furnace centre exceeded the exposure limit. The average pulse rate was measured at 150/min. It reached 65 to 83% of the maximum theoretical rate. The protective clothing worn by the workers was found to provide no protection against radiant heat and did not allow evaporation. It is recommended that this kind of repair work be limited to 2h and that an insulated floor be used to limit thermal radiation. Recommendations for periodical medical examinations are presented.
