叙述了瑞士沃尔芬斯伯哥铸造厂以漏斗包盖用于球墨铸铁的浇包处理的经验。为了适应球铁件和合金铸铁件增长的需求,于1980年完成了铸造厂的较大的扩建。在规划期间,顾问们考虑到为处理经镁处理产生的烟尘问题需要安装管道和抽风装置,并估计要化费15万美元左右。由于采用了漏斗包盖,铸造厂当即发现上述处置是不必要的,同时,发现它能满足保护 Describes the experience of pouring funnel-covered ladle for ductile iron in the Wolfensohnburg Foundry in Switzerland. In order to meet the growing demand for ductile iron and alloy castings, a major expansion of the foundry was completed in 1980. During the planning period, consultants took into account the need to install plumbing and ductwork to deal with the soot generated by magnesium treatment and estimated to cost about $ 150,000. As a result of the funnel cover, the foundry immediately found the above disposal is unnecessary, at the same time, found that it can meet the protection
