addition of ca cored wire in steel melt steel making
Welding - Wikipedia
This cored wire is more expensive than the standard solid wire and can generate fumes and/or slag, but it permits even higher welding speed and greater metal penetration.  Gas tungsten arc welding (GTAW), or tungsten inert gas (TIG) welding, is a manual welding process that uses a non-consumable tungsten electrode, an inert or semi-inert gas mixture, and a separate filler material.

Largest FCAW Wire for Out of Position Welding
In addition, a smaller diameter wire can be a little easier for the welder to handle. A 5/64" (2.0 mm) self-shielded flux-cored wire or a 1/16" (1.6 mm) gas-shielded flux-cored wire can be challenging to handle out of position, especially for less experienced welders.
Optimization of Aluminum Deoxidation Practice in the …
Samples from the steel melt and the slag were taken at the beginning of the process and after the first aluminum addition were made. The information obtained was analyzed in order to define the amount of aluminum required based on the initial oxidation conditions and measure the impact of the initial oxidation conditions on aluminum efficiency.
Influence of the chemical composition on steel casting …
2017/1/1· As known, carbon content directly influences the steel melting temperature, ranging from 1521 C in low-carbon steel (0.2%C) to 1486 C in high-carbon steel, as given in Table 1. The awareness of the liquidus temperature and steel temperature control in the refining and casting processes is essential to ensure the continuity of the productive process at melt shop  .

Desulfurization of steel [SubsTech]
2012/5/31· Sulfur (S) may dissolve in liquid iron (Fe) at any concentration.However solubility of sulfur in solid iron is limited: 0.002% in α-iron at room temperature and 0.013% in γ-iron at 1832 F (1000 C). When a liquid steel cools down and solidifies the solubility of sulfur drops and it is liberated from the solution in form of iron sulfide (FeS) forming an eutectic with the surrounding iron.

Ladle refining [SubsTech]
2012/5/31· In addition to deoxidation vacuum treatment helps to remove Hydrogen dissolved in liquid steel. Hydrogen diffuses into the CO bubbles and the gas is then evacuated by the vacuum pump. Movement of the molten steel caused by CO bubbles also results in refining the steel from non-metallic inclusions, which agglomerate, float up and are absorbed by the slag.
