Custom Sulphur Cored Wire

S Cored Wire Utilisation
Sulphur cored wire is made up of sulphur powder encased by a steel strip, hydrogen is produced when liquid steel is fed.

Hydrogen gas in the molten steel will cause bubbling and pinholes on the surface of the product, affect the texture of free-cutting steel.

When feeding into the sulfur cored wire, you have to blow argon at the bottom and deliver it mechanically, thus can reduce the cost.

Advantages of Sulphur Cored Wire
1. It is beneficial to adjust and control the sulphur content in liquid steel or iron, suitable steel or iron products with sulfur content can be obtained.
2. Add the sulfur to the molten steel, the sulfur recovery rate is more than 80%.
Add the sulphur to the stainless steel molten steel, it helps to improve the cutting performance of finished steel, change the morphology of vulcanized inclusion and improve the machinability.

FAQ of Sulphur Cored Wire
Is sulphur in sulphur cored wire harmful?
Any element has its advantages. As we often say, science always has two sides. In steelmaking, although desulphurization treatment is sometimes needed, people may not know that in the production of some special steel, sulphur cored wire is needed to be added to increase sulphur, so as to improve the cutting performance of steel.

What is the function of sulphur cored wire?
Sulphur cored wire is often used as a sulfur increasing agent in steel-making, which can effectively improve the cutting performance and toughness of steel. In casting process, sulphur cored wire can also play the role of inoculant, nodularizing agent, gray iron modifier and so on.

What are the applications of sulphur cored wire?
Sulphur cored wire is beneficial to adjust and control the sulphur content in molten steel or molten iron, and steel or iron products with appropriate sulphur content can be obtained. Adding sulphur into molten steel can be used to produce sulfur-containing free cutting steel, and the sulphur recovery rate can reach more than 80%. Adding sulphur into stainless steel liquid can improve the machinability of steel products, change the morphology of sulphide inclusions and improve the machinability.
