what's "forge slag"? - Bloomers and Buttons - .

14.07.2009 · When you forge bloom or wrought iron in a side blast forge with charcoal, you get a puddle of black slag that looks pretty similar to bloomery slag, I think that's what he's referring to, rather than scale. He also is specific that the best slag for this purpose is the slag .

I was reading Ole Evenstad's treatise on steel-making in a forge hearth, and I have one question: what does he mean by "forge slag" or "smithy slag...Hmm. Not sure, seems like they're using the slag as flux, could possibly be slag from the bloomery process. Do you have a link to the text in it's...I'm afraid I don't have one. I tried Google Books, but I only came up with a few references to the Evenstad book.Some of the text is confusing to read without some background knowledge. This is because of translation errors or misinterpretation of terminology...Matt- When you forge bloom or wrought iron in a side blast forge with charcoal, you get a puddle of black slag that looks pretty similar to bloomer...Pardon me,gents,if this will only serve to confuse things,but here are a couple of shots of SOMETHING,a creature that i've inadvertently produced a...That would be coal-slag, the more coal you burn the bigger they get. I doubt that it's the forge-slag mentioned in the article because at the time...Ah!Thanks,Leif,that makes sense.Of course,the mineral coal has been used but late in history,shoulda thunk that up meself! All in all,thanks to eve...Thanks, Lee. I've just recently been building a side-blast charcoal forge, actually, so it sounds like I'm headed in the right direction.Get Price

Smelting - Wikipedia

Smelting is a process of applying heat to ore in order to extract a base metal.It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.

Blacksmith - Wikipedia

This slag content made the iron very tough, gave it considerable resistance to rusting, and allowed it to be more easily "forge welded," a process in which the blacksmith permanently joins two pieces of iron, or a piece of iron and a piece of steel, by heating them nearly to a white heat and hammering them together. Forge welding is more difficult with modern mild steel, because it welds in a ...

Japanese Style Blade Forging : 7 Steps (with .

Forging is the process of creating a knife where the steel is heated then moved by repeated hammering, until it is in the shape of a knife. So why forge when you can use stock removal? 1) Steel waste: Stock removal requires lots of cutting and grinding. All the steel that is removed ends up becoming waste material, and is thrown away. With forging, I can often make a blade using ~70% the steel ...

The process of extracting iron from ore produces great quantities of poisonous and corrosive gases. In practice, these gases are scrubbed and recycled. Inevitably, however, some small amounts of toxic gases escape to the atmosphere. A byproduct of iron purification is slag, which is produced in huge amounts. This material is largely inert, but ...

Electro Slag Remelting Furnace, वैक्यूम .

Process Technology and Process Characteristics: Whereas VAR needs vacuum for refining, in ESR the consumable electrode is dipped into a pool of slag in a water-cooled mold. An electric current (usually AC) passes through the slag, between the electrode and the ingot being formed and superheats the slag so that drops of metal are melted from the electrode.

Electroslag Remelting [SubsTech]

31.05.2012 · An electroslag remelting process (ESR) starts when the lower tip of a consumable electrode is immersed into a pool of molten slag. The premelted slag possessing electrical conductivity is located on the water-cooled mold base connected to a power supply. The electric current (commonly AC) passing through the the slag keeps it at high temperature, which is about 360ºF (200ºC) higher than .

Steelmaking Process - an overview | .

During the steelmaking process, fluxes that consist of lime (CaO) or dolomitic lime, with iron and scraps, are charged to the furnace.There is a certain amount of free lime (f-CaO) in steel slag. Free lime, with a specific gravity of 3.34, can react with water to produce Ca(OH) 2, with a specific gravity of 2.23, which results in volume increase (Fig. 9.1).

Metal Forging - Manufacturing Process

The forging process is very important in industrial metal manufacture, particularly in the extensive iron and steel manufacturing industry. A steel forge is often a source of great output and productivity. Work stock is input to the forge, it may be rolled, it may also come directly from cast ingots or continuous castings. The forge will then manufacture steel forgings of desired geometry and ...

WELDING THROUGH FORGING - ENGINEERING

Welding can be achieved through forging, by heating up both pieces to very high temperatures (white heat indicator colour) and then 'hammering' them together. Mild steel requires a slightly lower temperature, yellow heat approaching white heat. Getting the temperature right is very important. If the temperature is even slightly lower than it should be, hammering will not produced a welded ...
