    • The invention is used in the field of metallurgy, in particular, for smelting, reducing, alloying and treating steel. The method involves loading a feedstock and feeding pressurized natural gas and either air or oxygen from below to melt the feedstock using a gas and air or gas and oxygen torch. The natural gas and either air or oxygen are fed via a non-water-cooled gas and air or gas and oxygen injector in the form of two concentrically mounted pipes, which is situated in an opening in the nozzle of the ladle slide gate and is surrounded by dry refractory sand. The natural gas is fed through the outer pipe and the air or oxygen is fed through the inner pipe. The ladle furnace is covered with a lid that is provided with electrodes and the feedstock is additionally melted from the top by electric arcs. After the melting process, a primary slag is skimmed from the ladle furnace, fluxing reagents are added to produce a secondary slag and inert gases and slag-forming reagents are blown in from below, combining this process with boiling, reduction, alloying, deep desulphurization and dephosphorization and the homogenization of the chemical composition and temperature of the finished steel. The invention enhances the quality of the steel and lowers the production cost thereof.

    • A method and arrangement for removing solid particles and tar component from carbon monoxide gas. In the method, carbon monoxide gas is conducted from a ferroalloy smelting furnace to a gas scrubber, the carbon monoxide gas is scrubbed in the gas scrubber by a liquid medium for removing part of the solid particles, the carbon monoxide gas is conducted from the gas scrubber to a blower, the flow rate of the carbon monoxide gas is increased by the blower, and the carbon monoxide gas is conducted to a particulate filter and the remaining solid particles are essentially filtered in the particulate filter from the carbon monoxide gas. Prior to conducting the carbon monoxide gas to the particulate filter, it is conducted to a particle feeder (4), where finely divided adsorbent particles (A) are fed in the carbon monoxide gas for adhering the tar component on the surface of the adsorbent particles, and the carbon monoxide gas flow containing adsorbent particles is conducted to the particulate filter, in which case the tar component adhered on the adsorbent particles is discharged in the particulate filter.
