Detailed Introduction
Product name: Sulfur
Type: pure sulfur
Melting point: 119℃(300°F)
Boiling point: 444℃(832°F)
Density under 20℃(68°F): 2.05g/cm3
Application:
Sulfur is considered as a kind of harmful impurity and it is controlled as low as possible while steel-making.
Although sulfur has some negative effects, it is often used to improve the machinability of steel and it can also reduce the tool wear.
The solubility of sulfur in the steel is relatively low. The main purpose of sulfur in the liquid steel is the formation of a particular ingredient or complex inclusions to improve the steel machinability. Sulfur is usually added to the liquid steel in the form of pure sulfur, iron sulfur or pyrite. Because the density and boiling point of sulfur is pretty low, feeding sulfur wire is a kind of effective way to add the sulfur.
Specification
Dia 9mm cored wire is a kind of medium size wire, which is suitable for the ladle of capacity less than 20 MT and most of cast iron spheroidization

The above fill rates can be adjusted upon request. The thickness of steel strip is 0.35~0.50mm, which conforms to the stipulation of GB716、GB3526、GB1323. The weight allowance for each 200g is no more than 2.5%. The joints for each 1000 meters are no more than 3. The cored wires are widely used for calcium treatment and microalloying in the ladle metallurgy, which have the advantages of element precise control and easy use.
