FIELD: metallurgy. ^ SUBSTANCE: mould cavity accommodates branch pipe made from highly resistant refractory material and is filled with liquid metal via branch pipe to metal level on feeding slag-forming mix onto metal mirror. In filling the mould, distance between branch pipe outlet and mould bottom is increased by upping the ladle. ^ EFFECT: higher quality of ingot due to ruling out metal contamination by oxides. ^ 1 dwg, 1 ex |
