FIELD: metallurgy.
SUBSTANCE: invention refers to special electrometallurgy, particularly to crystallisers of vacuum arc and plasma-arc furnaces. The crystalliser consists of a solenoid made in form of successively connected windings and is equipped with a distributor-collector with movable electro-contacting brushes and with a mechanism of reciprocal motion of brushes along contact surfaces of collector's plates and removable ferromagnetic tools of cleaning interacting with working surface of a barrier under effect of magnetic field alternately created with windings of the solenoid.
EFFECT: facilitates using magnetic field of solenoid for cleaning working surface of barrier and bottom plate from sublimates of melting and also for removal of electro-insulating film from contact surface of barrier and bottom plate.
