METHOD OF PROCESSING OF MOLTEN METAL IN LADLE AND UNIT FOR ITS IMPLEMENTATION (VERSIONS) Russian patent published in 2015 - IPC C21C7/00 

FIELD: metallurgy.

SUBSTANCE: in the method the coil is based on the surface of initial winding of wire, the respective internal surface of the coil, unwinding is performed from its outer side in the sequence, reverse to initial winding of wire, with compulsory synchronization of speed of unwinding of wire with supply into liquid metal, and during the operation of the supply rollers in the reverse mode the return synchronous winding of coil wire is performed. Besides, the device of wire supply into a ladle can be implemented as the single strand tribe-device with multimode supply, including the possibility of supply in the reverse mode, or in the form of the multi-strand tribe-device with multimode supply, including the possibility of supply in the reverse mode.

EFFECT: invention allows to eliminate twisting and stretching tensions in the supplied wire, and also to improve the accuracy of positioning, dosing, efficiency of assimilation of additives and to lower requirements to physico-mechanical characteristics of the powder wire shell.
