Abstract
Ramming compounds based on Latnensk clay-containing quartz sand and intended for the monolithic lining of steelcasting ladles were developed and tested and are now in production. The average durability of the lining of the 180-ton steelcasting ladles of converter section No. 1 of the Novolipetsk Metallurgical Plant is 9–10 melts when it consists of a ramming compound produced from Latnensk quartz sand. The lining becomes unserviceable owing to the low durability of the working layer of the bottom. When using a ramming compound based on Chasov-Yar semifatty sand, the lining of the lateral parts of the ladle bottom and that of the slag zone are severely eroded after 7–8 melts.
