METHOD OF HEATING OF CASTING LADLES AND DEVICE FOR ITS EMBODIMENT Russian patent published in 1997 - IPC

Abstract RU 2092277 C1

FIELD: metallurgy. SUBSTANCE: method includes supply of combustible gases together with oxidizer to working vessel of casting ladle through its cover, burning of gas mixture and also additional supply at pressure from the side walls of ladle to under cover of oxygen at flow rate of 0.8-1.2 n cu. m/h per ton of ladle capacity. The device for embodiment of the offered method has refractory lining with axial hole, burner, incoming into working hollow of casting ladle, and stand. Made over perimeter of cover are side holes with stationary branch pipes with pipelines installed opposite to the side holes. EFFECT: improved ecological conditions in zone of ladle heating. 2 cl, 1 dwg, 1 tbl
