特殊高温作业中的热修工,担任定期维修及临时抢修炽热炉体(如炼钢平炉、玻璃熔窑等)的任务,往往在极度高温(45～50℃)强烈热辐射(黑球温度90～100℃、单向热辐射强度15卡/厘米~2·分)的条件下进行作业(劳动强度中等——消耗能量3.1千卡/米~2·分),虽穿着防热用的白帆布厚棉衣和佩戴兰色防护眼镜,但作业时生理变化高度紧张(体温高达39℃。皮温高达38.4℃、脉搏174次/分),短时间大量出汗(平均53.5
Special hot work in the hot mechanic, as a regular repair and temporary repairing the hot furnace (such as flat steel furnace, glass furnace, etc.) task, often in the extremely hot (45 ~ 50 ℃) intense heat radiation (black ball temperature 90 ~ 100 ℃, unidirectional heat radiation intensity of 15 cal / cm ~ 2 · min) (moderate labor intensity - energy consumption of 3.1 kcal / m ~ 2 · min), although wearing a white canvas with heat Thick coat and blue protective glasses, the physical changes during the exercise are highly stressful (body temperature as high as 39 ° C, skin temperature as high as 38.4 ° C and pulse rate 174 beats / min) and a large amount of sweating in a short period of time
