Abstract The distribution and types of non-metallic inclusions in rimming steel ingotsobtained by four different teeming practices have been investigated microscopically.The different teeming practices were: (1) ordinary, (2) slag covering, (3) coveredtop of ingot mould during teeming, and (4) same as in (3), but immediately afterthe completion of teeming, a heavy steel plate was placed on top of the moltenmetal. Quantitative results indicate that the types and distribution of non-metallicinclusions in these ingots are basically similar, except that oxide networks alonggrain boundaries were observed in ingots obtained by using the last three teemingpractices. Several interesting phenomena are revealed and discussed. Suggestionsto improve the teeming practice are given.
