Description

The sliding nozzle being used currently is consisted of refractory plates and a nozzle bore for controling steel teeming process here in Japan and the said nozzle is being used all over the world with faster tempo.<br>The refactory parts are required to have, in their degree. more precise dimensions than those of conventional ones.<br>Particularly, each sliding glassy surface of the slide plates needs to be polished.<br>This sliding nozzle has been applied in degassing process, vacuum casting, continuous casting etc. and its excellency is duly confirmed under each operation.<br>Generally, in ingot teeming, 2 or 3 heats have been made without changing refractory parts.<br>After the experiment using 2 ton ladles we obtained the result of continuous usage of 14 charges as the maximum.<br>Application of this sliding nozzle is supposed to be important in future for improving automation of steel making process.
