目前中小企业特别是乡镇企业炉前都缺少检测仪器,如何及时、准确地判断铁水质量尤为重要。观察炉渣、三角试片、表面氧化膜(花纹)、火花、火苗等方法都是大炉师傅、铸造工作者长期实践的总结。这些检验方法中,我们认为观察铁水表面氧化膜乃是最简单、迅速、可靠的方法。

At present, small and medium-sized enterprises, especially township enterprises, lack testing instruments in front of furnaces. It is particularly important to judge the quality of hot metal timely and accurately. Observing the slag, triangular test strips, surface oxide film (pattern), sparks, flames and other methods are the master of the furnace, foundry workers long-term practice summary. Among these test methods, we think that the simplest, swift and reliable method for observing the oxide film on the hot metal surface is the best.
