AbstractThe effect of B2O3 on slag-metal reaction between CaO-Al2O3-based mold flux and high aluminum steel was investigated. The results showed that the addition of 5 % B2O3, the slag-metal reaction hardly occurred. When the content of B2O3 was increased, the reaction rate increased rapidly. This indicated if only considering the slag-metal reaction, it’s better for high aluminum steel casting if the addition content of B2O3 is less than 5%. The chemical reaction was greatly influenced by the reaction time. With higher content of aluminum ([Al]=0.1 %), the early stage of reaction was greatly affected by the reaction time, and furtherly, the influence was decreased. When the aluminum content was increased, the effect of [Al] on the slag-metal reaction was comparatively small in the initial 10 min, and the content of [B] was increased slightly. But when the reaction time increased to 1 hour, the slag-metal reaction acutely occurred, and the content of [B] increased rapidly.

The present work aimed to evaluate the health risks of occupational exposure to heavy metals in a steel casting unit of a steel plant. To determine occupational exposure to heavy metals, personal air samples were taken from the workers’ breathing zones using the National Institute for Occupational Safety and Health method. Noncancer and cancer risks due to the measured metals were calculated according to the United States Environmental Protection Agency procedures. The results indicated that the noncancer risks owing to occupational exposure to lead (Pb) and manganese were higher than the recommended value in most of the workstations. The estimated cancer risk of Pb was also higher than the allowable value. Moreover, the results of sensitivity analysis indicated that the concentration, inhalation rate, and exposure duration were the most influencing variables contributing to the calculated risks. It was thus concluded that the present control measures were not adequate and further improvements were required for reducing the exposure levels.
