摘要： A process by which molten solder is purified in-situ, making the soldering process more efficient and yielding better results, particularly for lead-free soldering. Lead-free solder becomes practical for use since the temperature for reliable soldering is reduced. A layer of active additive is maintained on the surface of molten solder for scavenging metal oxide from the solder and assimilating metal oxide into a liquid layer. The active additive is an organic liquid having nucleophilic and/or electrophilic groups. As an example, a layer of dimer acid maintained on a wave soldering apparatus scavenges metal oxide from the bath, and assimilates dross that may form on the surface. Scavenging metal oxide cleanses the bath and lowers viscosity of the solder, and PC boards or the like soldered on the wave have reliable solder joints.

摘要： The invention relates to a preparation method for stainless steel slags and modified steelworks slags for recovery of metal. In order to create a dry preparation method which guarantees a low wear and energy efficient comminution and de-agglomeration of stainless steel slags and modified steelworks slags as well as a selective separation of a metal fraction and a silicate fraction and which can be variable in relation to the different slag compositions and different requirements upon the quality of the metal fraction and the at least one silicate fraction, a roller mill is used at least for the comminution. The slags are supplied with a feed grain size of up to approximately 150 mm. The use of an air swept roller mill is advantageous, in which the comminution and de-agglomeration, if necessary drying, and at the same time a separation into an extensively mineral-free metal fraction and a virtually metal-free silicate fraction are brought together. When using an overflow roller mill the separation of the metal fraction and the silicate fraction takes place in an external classifier.
