محفور سلك مستعمل لصناعة الصلب

Alloys cored wire is a special form deoxidizer for the steelmaking industry. It is a core wire made of various specific alloying element powders or grains, physically mixed in a certain proportion, and then tightly wrapped with a thin iron sheet.Core-core wire can more effectively add smelting materials into molten steel or molten iron in the process of steel making or casting, and the core-core can be inserted into the ideal position through professional wire feeding equipment. When the core-skin melts, the core can be fully dissolved in the ideal position and produce chemical reaction, which effectively avoids the reaction with air and slag and improves the absorption rate of smelting materials. Widely used as deoxidizer, desulfurizer, alloy additive, can change the inclusion form of molten steel, effectively improve the quality of steel casting products.
