Metallurgical Product Description

Seamless pure calcium cored wire is welded using special technology so that it is fed in at a suitable speed, melts at the bottom, adheres closely to the ladle, and is highly absorbed by the molten steel. The interior of the seamless metal pure calcium wire is metallic calcium with a composition of more than 97%, and the exterior is 08 aluminum steel strip, which is guaranteed to be able to calcify after feeding. Seamless metal pure calcium wire does not contain silicon and is more suitable for melting TF steel, SPHC, SPHD, etc.

Product Parameters

Product Advantages

Long storage time (can be stored for a long time, the calcium core will not oxidize for two years, and the seamed calcium thread will oxidize for half a year)

Reduce the splash of molten steel when feeding wire (the splash of ordinary Cal welding wire is very strong when feeding wire)

Calcium content is more accurate and stable (52g/m) with high yield (less calcium consumption in processing)

High reproducibility (little fluctuation in residual calcium value) and little adsorption of harmful gases (H, N, etc.)

Manufacture And Use

Calcium silicate cored wire can purify molten steel and partially change the nature and form of inclusions, improving the quality of molten steel and improving the casting state. After putting it into steel, it can improve its mechanical properties to a certain extent, making it convenient for people to use. It can reduce temperature loss and improve steel production efficiency.

Applications

Core-clad wire has been widely used in the ladle refining process. It is a linear material formed by wrapping a powdery additive package (deoxidizer, desulfurized, alloy) crushed into a certain particle size in a continuous narrow steel strip, and Wound into wire rolls, the functions and uses of core-spun wires vary depending on the core powder.

Because it is beneficial to adjust and control the content of easily oxidized elements and trace elements, it can greatly increase the alloy yield, reduce smelting costs, shorten smelting time, and control composition.

Calcium silicate cored wire is suitable for deoxidation and desulfurization in steelmaking. It can improve the properties of steel, and improve the plasticity, impact toughness, and fluidity of molten steel. It also has the characteristics of directly entering the molten steel for melting and uniform distribution.
