Effects of tellurium addition on the removal of alumina clusters from molten steel were investigated. The results obtained are summerized as follows:
(1) Experiments were performed on 0.5kg melt, and it was observed that telluerium had a remarkable effect of ejecting alumina clusters from molten steel.
(2) A small amount of tellurium (about 0.002%) was sufficient to obtain this effect.
(3) The ejection of alumina clusters by tellurium was considerably rapid.
(4) Sulfur and selenium also showed similar effects; nevertheless tellurium showed the most remarkable effect among them.
This phenomenon was also observed in the case of 50kg and 500kg ingots
