Use of graphite-containing nozzles for vacuum casting of ingots

Abstract

The quality of the gunited coating makes it possible to continuously cast up to five heats in a single series and the specific consumption of the guniting compound is 1.5-1.6 kg/tonne of steel. The hardened residues of metal and slag are removed from the tundish without difficulties. No increase in nonmetallic inclusion content of the steel in comparison with the period of use of imported compounds was noted. CONCLUSIONSUnder the conditions of the Electric Melt Shop of Belorussian Metallurgical Plant a guniting compound composition has been developed and a production method has been intnoduced for guniting of the lining of tundishes for casting of cord, cable, and alloy steels. i. 2.3.
