When it comes to refining outside the furnace, we have to talk about the technology of cored wire. It is a technology specifically designed to improve refining efficiency. With years of development and application, the current technology has been very perfect and can be used for all kinds of smelting. It is used in Some equipment is required when feeding. So how does it improve smelting quality? Let's find out together below.
Core-covered wire can not only improve quality, but also improve the fluidity and castability of molten steel on the continuous casting device and in the steel mold, reduce splashing into the atmosphere, and reduce equipment costs and production consumption. The steel sheath of the cored wire protects the active agent from the atmosphere and moisture during storage and transportation, prevents its oxidation when passing through the slag layer, and ensures the required rigidity for insertion into the melt to a given depth.
When changing the speed, diameter, thickness of the cored wire and the quantitative relationship between each component of the filler, the contact time between the agent and the molten steel can be adjusted, as well as their interaction speed.
