Why should copper mould tube have taper

[vc_row][vc_column][vc_column_text]As the molten steel is cooled in the mould, the blank shell of a certain shape is formed. With the continuous downward movement of the casting blank, the temperature also decreases and contracts, and a gap is formed between the mould and the blank shell, which is called an air gap.The existence of air gap reduces the cooling effect. At the same time, because the blank shell is separated from the inner wall of the mould too early, the blank shell will be deformed under the action of molten steel static pressure. Therefore, the inner cavity should have a taper, which is generally large at the top and small at the bottom, to reduce the air gap.
