Stopper for reliable gas injection |
摘要 |
<p>The present invention concerns a mono-block stopper adapted to deliver gas during pouring of molten metal comprising a stopper body having an internal chamber ( 1 ) and a gas discharge port ( 2 ), a bore ( 3 ) connecting the internal chamber ( 1 ) to the gas discharge port ( 2 ), calibrating means ( 4 ) being provided in the bore ( 3 ) to provide a restricted path. This stopper is characterised by the fact that the calibrating means comprise a rod ( 4 ) having at least one axially-extending gas passages therealong, the gas passage(s) having a section such as to offer a predetermined resistance to flow. The stopper of the invention is far more reliable and can be easily adapted to various operational parameters.</p> |
