FIELD: metallurgy.
SUBSTANCE: proposed method comprises fitting of detachable insert in retort with clearance between return wall and insert. Lining material is filled in clearance between insert and return wall to make return lining. Insert is withdrawn to fit return in place with made lining into furnace. Note here that liquid slag of previous smelting is used as retort lining tapped from the furnace via tap hole into the other, specially prepared retort outside the furnace. Retort with discharged slag is withdrawn from the furnace and lined with application of liquid slag of previous melting for next melting in the furnace for metal-thermal reducing fusion. Insert can be composed of several parts.
EFFECT: shortened melting cycle, controlled lining wall quality.
