contact usslag to reclaim it). However, if the SAW slag can be reused as flux merely after crushing it to the particle size of the original slag, without any new additions/further processing, the cost of reuse of the slag will be quite low. But the qual-ity of clad metal obtained using this reused slag needs to be analyzed before recommending/
contact us· Fig 4 Schematic diagram of a slag granulation plant. Granulation section – Here, the liquid BF slag is water quenched and solidified into small particles, eliminating the need for heavy crushing equipment. The liquid slag flows by runners from the BF to the granulation unit. From the runner, the liquid slag stream at around 1,500 deg C is poured into a high velocity water stream at the ...

contact us(2) Melted Flux (Crushed Slag). Melted flux or slag removed from a weld deposit may be crushed and used as a SAW flux again. However, it must be recognized that this crushed slag is likely to be a chemically and physically different flux from the unmelted flux. It shall therefore require separate certification testing for the particular dry mix or lot of crushed slag, according to the ...

contact us· The mixture of oxidized impurities and flux becomes slag, which is scraped away to reveal the pure gold at the bottom of the crucible. Because borax is so cheap and effective at extracting gold, borax-based refining techniques were very popular during the 19th century gold rushes. It still continues today among individual prospectors and small ...
contact usThe fused fluxes are acid, neutral or slightly basic and are manufactured by mixing the constituents together, melting them in an electric furnace and crushing the solidified slag that is produced to give a flux with a glassy appearance.

contact us· There are two kinds of slag formation in blast furnace. When smelting with ordinary acid ore, the flux is loaded into the blast furnace in the form of limestone, and the Cao in the flux can not be in close contact with the acid oxides in the ore. therefore, the slag initially formed is mainly fe2sio4 formed by SiO2, Al2O3 and a part of reduced FeO.
