WORD OF THE DAY
On its way from the blast furnace to the converter or open hearth furnace the pig iron is often passed through a great reservoir called a " mixer," which acts also as an equalizer, to lessen the variation in composition of the cast iron, and as a purifier, removing part of the sulphur and silicon.
This " mixer " is a great reservoir into which successive lots of molten cast iron from all the blast-furnaces available are poured, forming a great molten mass of from 200 to 750 tons.
Should several furnaces simultaneously make iron too rich in silicon, this may be diluted by pouring into the mixer some low-silicon iron melted for this purpose in a cupola furnace.
In like manner, if the molten iron in the mixer contains manganese, this metal unites with the sulphur present, and the manganese sulphide, insoluble in the iron, slowly rises to the surface, and as it reaches the air, its sulphur oxidizes to sulphurous acid, which escapes.
As a middle shade for the mixer, try using something with an orange shade (that's right, I said orange...give it a try) mixed with a warm gold tone, maybe with a slight shimmer, it will give your eyes life and brighten them up.
Further, an important part of the silicon may be removed in the mixer by keeping it very hot and covering the metal with a rather basic slag.
Looking at the duplex process in another way, the preliminary desilicidizing in the Bessemer converter should certainly be an advantage; but whether it is more profitable to give this treatment in the converter than in the mixer remains to be seen.
It is true that the use of the " mixer " (§ 77) lessens these variations, and that there are convenient ways of mitigating their effects.
This rugged hand held mixer stands upright on a non-skid base and it can easily and effectively replace up to four different kitchen appliances, including a blender, a mixer, a food processor and a wand mixer.
Air lifts were pieces of ancillary equipment for lifting melted bitumen up to the mixer on top of the plant.
Mixing in GigaStudio GigaStudio 3.0 has a capable digital mixer built-in, with 128 channels and 32 fader groups.
Other feature refinements include added output busses, with up to 8 stereo outputs now available within the virtual mixer of the host application.
