METHOD OF TORCH GUNITING OF LINING OF CONVERTER WITH PRELIMINARY SCRAP HEATING Russian patent published in 1995 - IPC

Abstract SU 1632050 A1

FIELD: ferrous metallurgy. SUBSTANCE: method provides for creation of conditions of effective use of fuel both fuel component of gunite-mass during guniting and fed in converter fuel. For the purpose after carbon-containing fuel feeding on cold scrap they exercise torch guniting of lining with ratio of gunite-mass feeding intensity and oxygen as 1 : 1.2 - 2.0. EFFECT: method provides decrease of pig-iron consumption by 36 kg per ton of steel in following after torch-guniting smelting. 1 tbl
