Cored Wire Features

Cored wire In the field of foundry industry, powder core wire is usually called cored wire, mainly in three aspects: breeding, refining outside the furnace, and special element alloying. Fixture performance testing, testing the overall performance and function of welding fixtures.

The cored wire technology is an external refining method developed on the basis of jet metallurgy technology in the 1980s. Cored wire is suitable for steelmaking and casting. Used in steelmaking to purify the shape of steel inclusions, improve the castability of molten steel, improve the performance of steel, and significantly increase the yield of alloys, reduce alloy consumption, reduce steelmaking costs, and have significant economic benefits.


1. It is beneficial to adjust and control the content of easily oxidizable elements and trace elements, which can greatly increase the yield of the alloy, reduce the smelting cost, shorten the smelting time, and accurately control the composition.

2. It plays the role of pure molten steel and partially changing the properties and morphology of inclusions, improving the quality of molten steel and improving the casting state.

3. The cored wire is divided into two types: inner draw type and outer draw type. The machinery and equipment required for feeding the wire are simple and reliable, and the floor area is small. Especially the inner draw type cored wire is more suitable for use in narrow places.
