引言 (一) 冰见工厂的溶化设备和集尘方式冰见工厂没有二台15T电弧炉,分别作为铸钢用和铸铁、球墨铸铁的溶化用。并设有一台集尘装置,采用间接吸入式来处理两炉的排尘。目前,集尘方式一般采用直接吸入方式。这种直接吸入式在氧化期中不能完全吸入排尘以及在还原期为了保证炉内还原性气氛的存在,而不得停止吸入排尘,因而存在着 Introduction (a) See the melting plant ice melting equipment and dust collection method See the factory does not have two 15T arc furnace, respectively, as cast steel and cast iron, ductile iron melting use. There is also a dust collection device that uses indirect suction to treat the two furnaces. Currently, dust collection methods generally use direct inhalation. This direct inhalation in the oxidation period can not be completely inhaled dust and reducing the furnace in order to ensure the existence of reducing atmosphere, but not to stop inhalation of dust, so there is
