CALCIUM SILICON CORED WIRE

Calcium Silicon alloy is widely used to improve the quality, castability and machinability of steel.

Calcium is a powerful modifier of oxides and sulfides, It transforms alumina inclusions into coplex Calcium aluminate compounds, improving the castability of the steel in a continuous casting process. Other benefits include reduction in deposits of solid inclusions inside of the tundish nozzles, preventing clogging. Calcium also improves steel’s machinability, increasing the life of cutting tools.

This product has been developed for the Calcium treatment of Al-killed, restricted-Silicon-content steels.

MANUFACTURING METHOD

Crushing the additives (CaSi alloys) into certain granulation (in the form of powder), then, using the equipment to fill the powder into the "U" shaped sheath, which is made of high quality cold rolled steel strip, lastly, tightly closing the wire, so a multiple material(cored wire) with certain length will be obtained.

CHEMICAL COMPOSITION

For a 13 mm wire, as per the requests of aghasteel, the Calcium Silicon linear density is shown in the table below:

  application technology.The implementation process of this technology is: on the core machine adopts steelskin belt to add to or mental break into a certain size of all kinds of additives (such as deoxidizer, desulfurizer, inoculant, alloy, etc.) with arbitrary length of bag wrapped into a conductor, and then by means of wire feed machine will pack conductor to a certain speed through the molten steel or on the surface of the molten slag layer to the bottom of the ladle or hot metal ladle.As the package of conductor skin constantly fusion, wrapped in its internal additives will slowly into the molten steel or hot metal, by additive and its surrounding or mental interaction to achieve the purpose of refining outside the furnace (deoxidization, desulphurization and metamorphism, ball, vermicular, alloying, etc.).
Along with the rapid development of the feed line technology in various fields, the increasing demand for various alloy core, manufacturing high molding speed, high degree of automation, automatic quantitative feeding core machine will be the development direction of future packet core production technology, in addition, the development of new type, high efficiency, environmental protection bag core powder and feed line technology development of one of the important link.

HOW TO USE

By using feeding machine to inject the Calcium Silicon cored wire with exact length reaching into the bottom area of Ladle at an reasonable speed, along with the melting of wire sheath, the included powder will be evenly dispersed & reacts with the liquid steel inside the ladle.

Calcium Silicon cored wire is more advantageous compared with use of powder spraying method and putting ferro alloy directly in.

1) Adjusting steel ingredients accurately. 

2) Improving alloy receiving 

3) Avoiding gas into steel liquids

4) To let Steel liquid reacts stably, and make it more purity.

5) Strong adaptability and wide application.

6) Convenient operation and maintaining environment without pollution

PACKING

For protction from moisture and damage during transportation and storage, coils are encased in a steel shelf and then wrapped with 2-ply transparent plastic film, 1-ply red polypropylene plastic woven outer. 10-20 coil can be shipped in a 20 ft container (up to size option). Other packing option are available upon request.
