A substance added to molten steel for the purpose of removing oxygen. The first requirement of a deoxidizer is that it have an affinity for oxygen in molten copper. Probably the second most important requirement is that it be relatively inexpensive compared to copper and any other additions.
- Deoxidizer Options Available:
1) Alumina Flux-
used by metallurgical companies as steel and slag deoxidizer.
2) Aluminum Metal-
is widely used as a deoxidizer. Aluminum can control austenite grain growth in reheated steels and is therefore added to control grain size. Aluminum is the most effective alloy in controlling grain growth prior to quenching. Titanium, zirconium, and vanadium are also valuable grain growth inhibitors, but there carbides are difficult to dissolve into solution in austenite.
3) Calcium Metal-
recent developments have found that carbon and alloy steels modified with small amounts of calcium might show improved machinability and longer tool life. Transverse ductility and toughness are also enhanced.
4) Calcium Silicate-
acts as a deoxidizer and degasifier when added to steel
5) Ferro Silicon-
the main use is as a deoxidizer of molten steel.
6) Hydrogen- is, of course, a strong deoxidizer, limited only by the amount of water vapor content.
7) Manganese Metal-
a mild deoxidizer and desulfurizer. It is generally beneficial to surface quality especially in resulfurized steels. Manganese contributes to strength and hardness, but less than carbon. The increase in strength is dependent upon the carbon content. Increasing the manganese content decreases ductility and weldability, but less than carbon. Manganese has a significant effect on the hardenability of steel.
8) Silicon Metal-
is one of the principal deoxidizers used in steelmaking. Silicon is less effective than manganese in increasing as-rolled strength and hardness. In low-carbon steels, silicon is generally detrimental to surface quality.
9) Silicon Carbide Grain-
is an effective slag deoxidizer, as well as an excellent source of silicon and carbon. It’s low aluminum, sulfur and nitrogen content make it a very cost effective material to replace Ferrosilicon or Silicomanganese.
10) Silicon Manganese-
it is essential as a deoxidizer and a desulphurizing agent.
11) Zinc Metal-
although zinc normally functions as a solid-solution strengthener, it is sometimes added in small amounts to function as a deoxidizer, because it has high affinity for oxygen and is relatively low in cost.
