One of the major achievements in the present-day steelmaking and foundry industries is the development of a cored wire injection method for modification of steels and irons in ladles and its industrial application.
Currently, NPP supplies cored wires with various filler materials 10, 13, 14 and 15 mm in diameter. The filler materials may be single- or multi-component, fused or blended.
The cored wires with the following filler materials are supplied by NPP on a commercial basis:
