Deoxidized steel - Wikipedia

Deoxidized steel (Also known as killed steel) is steel that has some or all of the oxygen removed from the melt during the steelmaking process. Liquid steels contain dissolved oxygen after their conversion from molten iron, but the solubility of oxygen in steel decreases with cooling. As steel cools, excess oxygen can … Visa mer There are four types, ranging from fully deoxidized to slightly deoxidized: killed, semi-killed, rimmed, and capped. Note that none of the various types are better than the other as each is useful in its own regard. Visa mer Rimmed steel, also known as drawing quality steel, has little to no deoxidizing agent added to it during casting which causes carbon monoxide to evolve rapidly from the ingot. This causes small blow holes in the surface that are later closed up in the Visa mer • Decarburized steel Visa mer Killed steel is steel that has been completely deoxidized by the addition of an agent before casting such that there is practically no … Visa mer Semi-killed steel is mostly deoxidized steel, but the carbon monoxide leaves blowhole type porosity distributed throughout the ingot. … Visa mer Capped steel starts as rimmed steel but part way through the solidification the ingot is capped. This can be done by literally covering the ingot mold or by adding a deoxidizing agent. The top of the ingot then forms into a solid layer of steel, but the rim of the … Visa mer WebbOxidizing agents: The corrosion process is conditional on an anodic reaction and a cathodic reaction taking place simultaneously.
