摘要:
For the procedure a gas, heated to at least 1000 degrees Celsius, preferably even beyond the liquid temperature of the melt, is blown into the discharge opening (26). In this manner freezing problems and deposits in the discharge opening can be largely prevented. The pouring sleeve (20) according to the invention has a gas supply line (21), leading into a gas permeable insert (23) surrounding the opening (26), which is led for a certain length along the upper range of the sleeve (20) which is in contact with the melt, for the purpose of heating the gas.
