在金属冶炼过程中,除存在冶炼金属自身的职业病危害外,还存在伴生金属、非伴生金属矿脉粉尘、冶炼药剂以及生产过程中产生的无机或有机毒物、高温、噪声等职业病危害因素。炼钢作业是金属冶炼行业中的典型代表,其中,电弧炉炼钢是利用电能通过石墨制的电极与金属原料之间产生电弧(电弧温度可达4 000℃)作为热源来进行冶炼。下面就电弧炉炼钢过程中产生的职业病危害因素进行识别,并提出控制措施和职业病
In the metal smelting process, in addition to the occupational disease hazards of smelting metal itself, there are also occupational disease hazards associated with associated metals, non-associated metallic veins dust, smelting agents and inorganic or organic toxicants, high temperature and noise generated in the production process. Steelmaking is a typical example in the metal smelting industry, where electric arc furnace steelmaking utilizes electric energy to generate electric arc (arc temperature up to 4,000 ° C) between electrodes made of graphite and metal raw materials as a heat source for smelting. The following EAF steelmaking process in the hazards of occupational hazards identified and proposed control measures and occupational diseases
