The inventions solve the problem of melting a steel wire which is extremely thin, including but not limited to the wire from the cord of worn out tyres, which is metal scrap separated in the disposal process of motor vehicle worn out tyres. The said cord poses a gross ecological problem. The essence of the invention submitted is the method of the thermal processing of contaminated steel wire, including but not limited to the cord of worn out tyres, whose characteristic is that a thin wire with contamination is heated continuously and gradually until the stage of the wire tempering in the temperature of 600 - 1000 Centigrade, and then, through the temperature growth, a thin wire is brought to the stage of melting and separation of slag and steel in the temperature from 1450 to 1550 Centigrade, and afterwards it is advantageous to conduct the process of continuous casting or die-casting of cast iron or steel with the use of the heated steel. The object of the invention submitted is the device for the thermal processing of contaminated thin steel wire, including but not limited to the cord of worn out tyres, whose characteristic is that regardless of the arrangement: vertical, diagonal or angular one, this device is equipped with a hopper, feeder, induction heating chamber and heating and melting induction furnace, re-heating and slag and steel separating furnace; whereas, steel flows through the upper outlet or/and lower outlet to the container/furnace, and in the vertical arrangement, the extraction system for fumes and gases is settled at the top of the container, and in the angular arrangement, it is settled at the joint of the feeder and/or induction pass-through heater. The invention under consideration is illustrated in figure 1.
