概况我们于1975年7月至9月对遵义铁合金厂某冶炼车间进行了劳动卫生调查和工人的体检。该车间冶炼硅锰、高硅锰、富锰渣及碳素锰铁,其设备及生产条件属该厂较差者,其主要生产工艺过程是:原料破碎→配料→炉边铺料,加料→电炉冶炼→出铁→浇铸车间职工人数为437人(男372人、女65人),其中生产工人为371人(男311人、女60人)。职工平均年龄为34.3岁,生产工人平均年龄为33.9岁,年龄分布情况参见表3。
Overview We conducted a labor hygiene survey and a worker’s physical examination of a smelter in Zunyi Ferroalloy Factory from July to September 1975. The workshop smelting silicomanganese, high silicon manganese, manganese-rich slag and carbon ferromanganese, the equipment and production conditions are poor factory, the main production process is: raw materials crushing → ingredients → Furnace paving, feeding → Electric furnace smelting → → → cast iron casting plant the number of workers 437 (372 men and 65 women), of which 371 were manufacturing workers (311 men and 60 women). The average worker age is 34.3 years old, the average age of production workers is 33.9 years old, and the age distribution is shown in Table 3.
