An effective method of refining outside the furnace is to treat the metal inside the ladle with a core wire. With the help of a gripper, the core wire adds chemicals, deoxidisers and alloying elements to the liquid metal, which reduces energy and material costs, improves the absorption of alloying elements in the melt and reduces their dispersion, and removes sulphur and non-metallic inclusions from the metal liquid.
Improve the quality of metal products. At this time, it can also improve the liquid steel flow and casting on the continuous casting device and in the steel mould, reduce the splash to the atmosphere, and can reduce equipment costs and production consumption. The steel cladding of the cored wire protects the active agent from atmospheric and moisture action during storage and transport, prevents its oxidation when passing through the slag layer, and ensures the required rigidity for insertion into the melt at a given depth.
The contact time between the agent and the melt, as well as the speed of their interaction, can be adjusted when changing the speed of the cored wire, its diameter, the thickness of the skin and the quantitative relationship between the components of the filler.
