对242名男性工人，12个炼铁、炼钢及其辅助作业岗位，进行高温作业分级和体力劳动强度状况分析，Ⅱ、Ⅲ级高温作业所占比例为16．7％和58．3％，Ⅱ、Ⅲ级体力劳动强度所占比例为35．5％和23．6％。提示高温作业分级与体力劳动强度状况综合评价更为重要。
242 workers, 12 steelmaking, steel making and auxiliary work positions were analyzed. The classification of high temperature work and the analysis of manual labor intensity were analyzed. The proportion of high temperature work in grade Ⅱ and Ⅲ was 16.7% and 58.3% respectively, Ⅱ, Ⅲ level of physical labor intensity accounted for 35.5% and 23.6%. Suggesting that the classification of high-temperature operation and physical labor intensity comprehensive evaluation of more important.
