What is the production as well as the use of core wire?
Metallurgical manufacturers are very detailed introduction of the core wire related content, for the core wire production process also let us have a little understanding, core wire production process includes raw material preparation, batching and mixing, core material preparation, cladding molding, cooling and curing, drawing and straightening, quality testing, and packaging and warehousing and so on many steps. Each step has a critical impact on the quality of the final product.
We also can supply other alloy core wire as following.

It also talks about some of the application areas of the core wire, in fact, in the steelmaking and foundry industry, the core wire is widely used in the liquid steel deoxidation, desulfurization, alloying and non-metallic inclusions denaturation treatment. Through the wire feeding equipment, the core wire can be inserted into the appropriate position of the molten steel, when the skin of the steel strip of the core wire is dissolved, the core of the wire in the appropriate position will be fully dissolved to produce a chemical reaction, which effectively avoids the reaction with the air and slag, so that it also greatly improves the absorption rate of the smelting material.
