Abstract (en)

[origin: DE19746728C1] The invention relates to a method and a casting nozzle for casting-on a metal strip which is close to final dimensions. According to said method, the melt, especially steel, is guided via a melt feed vessel in a pour-in chamber of a skimmer-type vessel and then from said pour-in chamber via a main chamber which is subjected to negative pressure, and finally onto a cooled transportation belt by means of a casting nozzle. The invention is characterised by the following steps: a) the pour-in chamber and the main chamber are filled to the top of the skimmer; b) the negative pressure device connected to the main chamber is activated before the melt flows over the skimmer top; c) after the melt has flowed over the skimmer top, the melt flow is guided through the casting nozzle in such a way that its cross-section closes in the manner of a plug; d) the negative pressure is increased according to the position of the plug in the cast nozzle until a hydraulic connection has been established in the melt flow between the inflow and the outflow, and adjusted so that melt flows out at the mouth of the casting nozzle; e) the melt level in the pour-in chamber is then kept at a value at which the inflowing melt flow is equal to the outflowing melt flow. The invention also relates to a casting nozzle for casting a metal strip close to final dimensions which is directly connected to a main chamber.
