Flux (metallurgy) - Wikipedia

In metallurgy, a flux (derived from Latin fluxus meaning "flow") is a chemical cleaning agent, flowing agent, or purifying agent. Fluxes may have more than one function at a time. They are used in both extractive metallurgy and metal joining. Some of the earliest known fluxes were sodium carbonate, potash, charcoal, coke, borax, lime, lead sulfide and certain minerals containing phosphorus.

Effect of chemical elements on steel - Tubecon

3. Sulphur (S): Even though the effect of sulphur on steel is negative at certain stages, any sulphur content less than 0.05% has a positive effect on steel grades. Sulphur contains a few disadvantages when the content is higher than 0.05%. Brittleness is caused and the weldability decreases as the sulphur content increases to more than 0.05%.

Neutralisation of acid effluent from steel manufacturing ...

Nov 12, 2019· In this study, an integrated electric arc furnace (EAF) dust slag/lime (Ca(OH)2) treatment method was used to treat acid effluent generated by the same stainless steel producer. EAF slag alone was able to raise the pH to 8.7; thereafter, lime was added to increase the pH to the target pH of 12. The test proved that EAF dust slag, in conjunction with lime, can be used for neutralisation of acid ...
