Metallurgical Powder Wire
The most com prehensible variant of processing became a power wire at continuous casting its input in reception section tundish is,
allowing, not breaking a slag mode in tundish and crystallizers to adjust not only the maintenance of entered microalloying elements
(calcium, titanium, aluminium, boron), but also to provide their fuller effective action on structure and properties of steel during its crystallization and
thermomechanical processing.
Round wire, diameter 14 mm. Filler: powder with grain size of not more
than 3 mm. Filler materials: silicocalcium CK-25,
ferrotitanium Ôòè70,
nitrided ferrosilicon, elementary sulphur, graphite and others - by agreement.
Wire fill factor for various fillers: 40-70%.
