炎夏,冶金行业的炼铁、炼焦、轧钢等生产场所,在艳阳,高炉烈焰及熔化的金属和灼热的钢锭等内外热源夹攻下,温度常可高达40～50℃,工人在这样的高温下进行长时间强体力劳动,难以维持正常的体温调节,就易发生中暑。 In the summer of summer, iron and steelmaking and metallurgical production sites in the metallurgical industry often have temperatures as high as 40 to 50 ° C under the heat and heat sources such as the sun, the flames of the blast furnace, the molten metal and the hot steel ingot. Workers are exposed to such high temperatures Long time hard labor, it is difficult to maintain normal body temperature regulation, prone to heat stroke.
