EFFECTIVE STEEL-TEEMING LADLES’ LINING

Abstract

The  reasons of steel teeming ladles’  lining’s  weak  resis- tance and  the bottom-pouring guide’s disturbances are  an- alyzed  in the article. The high-temperature glue was devel- oped  and  the  most  chemical stable refractories were se- lected. The  operational conditions of steel teeming ladles for open-hearth furnace’s shop  at the  Revdinskii hardware metallurgical plant (Revda)  are  regarded. According to the results  of   the   investigations  the   refractory  materials MKRAP were applied instead of the chamotte ware and the brick  mortar developed by the  authors was used, all of this increased the  ladles’   brickwork’s strength  by  30–50 %. The   application  of  highly-resistance,  high   temperature glue in the bottom-pouring guide reduced the metal losses. Ref. 3.
