一、前言现在铸造界对在铸铁中使用锑有比较一致的认识:只要控制好加入量,一般会得到较好的效果。如在大断面球铁中加入微量锑可防止中心石墨衰退;蠕铁中如采用稀土——锑复合蠕化剂,可大大增加稀土或硫的允许波动范围,从而稳定了蠕铁的生产。但是,到目前为 First, the preamble Casting industry now in the use of antimony have a more consistent understanding: as long as the control of the amount added, generally get better results. Such as the large section of nodular iron with trace antimony can prevent the center of graphite decay; vermicular iron, such as the use of rare earth - antimony compound vermiculite, can greatly increase the allowable range of fluctuation of rare earth or sulfur, thus stabilizing the production of vermicular iron. But so far
