In a method for melting and treating metals and metal alloys, especially steels, solid charge material is melted in a ladle. Then while passing a gas through the melt at least part of the time, at least one of the treatments of decarburization, dephosphorization, deoxidation, desulfurization, alloying and removing nonmetallic inclusions is performed in the same ladle. An apparatus for the practice of the method has two tracks (W1, W2) for the ladle (5), which are aligned in an approximate T-shape to one another, a preheating station (9) and a slag removal station (14) being arranged in the top part of the T and, at the intersection between the top part and the stem between the preheating station (9) and the slag removal station (14), the first treatment station (10) with a heating system is disposed, and at the free end of the stem of the T a second treatment station (16) for the vacuum treatment is disposed.
