通过对苏联几乎所有镁厂的调查,弄清了污染镁电解车间的介质因素和主要危害。对劳动条件的最大危害是氯含量超过允许值(达3.1～10.1毫克/米~3),热辐射太高(平均为8～25焦耳/厘米~2,最高达11～46焦耳/厘米~2),辐射温度达70℃;空气运动速度为0.6～6.0米/秒;各工作地点的磁场强度为50～400奥斯特,从生态学角度看,对人体有一定影响。按能耗计算,最繁重的工种是:人工出渣(每个电解槽每月出渣3次以上);更换阳极(阳极浸渍保护结果使更换阳极的时间间隔延长到12～16个月)和更换阴极;加料(每昼夜3～4次);出镁(每昼夜2次)。无隔板电解槽能保障提供较优越的劳动条件,这种电解槽的劳动消耗率是140人-分/吨镁(当使用
Through the investigation of almost all magnesian factories in the Soviet Union, the media factors and major hazards of the contaminated magnesium electrolysis workshop were clarified. The greatest hazard to working conditions is that the chlorine content exceeds the allowable value (up to 3.1 to 10.1 mg / m3) and that the heat radiation is too high (on average 8-25 joules / cm2, up to 11-46 Joules / cm2 ), The radiation temperature of 70 ℃; air velocity of 0.6 to 6.0 m / s; the magnetic field strength of the workplace at 50 ~ 400 Oersted, from an ecological point of view, have a certain impact on the human body. Calculated according to energy consumption, the heaviest types of workmanship are: manual slag discharge (more than 3 times a month for each cell); replace the anode (the anode immersion protection results in the replacement of the anode time interval extended to 12 to 16 months) and Replace the cathode; feeding (every day and night 3 to 4 times); out of magnesium (2 times a day and night). No separator electrolyzer can provide better protection of labor conditions, the electrolyzer labor consumption rate is 140 people - minutes / ton of magnesium (when used
