POURING LADLE HEATING METHOD AND APPARATUS

摘要

FIELD: metallurgy. SUBSTANCE: method involves supplying hot gas mixed with oxidizer into working cavity of pouring ladle through its cover; burning gaseous mixture; heating and supplying oxygen jets under pressure below cover at flow rate of 0.8-1.2 n cu m/hour per 1 t of ladle volume. Apparatus has lined cover with axial opening, burner extending into working cavity of pouring ladle and stand. Side openings are positioned along cover perimeter. Stationary branch pipes with pipelines are positioned in opposed relation with respect to side openings. EFFECT: increased efficiency, improved ecological conditions at places adjacent to pouring ladle and increased safety in workshop.
