Aug 11 2015 · Iron making evolved over a few thousand years Using the ancient bloomery method iron ore was converted directly into wrought iron by heating the ore while at the same time melting the ores impurities and squeezing them out with hand hammers This is also called the direct process

During the first stage of the process this iron is melted down to a fluid bath in the bottom of a reverberatory furnace Then the oxidation of the carbon contained in the iron commences and at the same time a fluid basic cinder or slag is produced which covers a portion of the surface of the metal bath and prevents too hasty oxidation

Direct reduction DR This is any process in which iron is extracted from ore at a temperature below the melting points of the materials involved Gangue remains in the spongelike product known as directreduced iron or DRI and must be removed in a subsequent steelmaking process Only highgrade ores and pellets made from superconcentrates 66 percent iron are therefore really suitable for DR iron

The sponge is removed from the furnace called a bloomery and repeatedly beaten with heavy hammers and folded over to remove the slag oxidize any carbon or carbide and weld the iron together This treatment usually create wrought iron with about three percent slag and a fraction of a percent of other impurities Further treatment may add controlled amounts of carbon allowing various kinds of heat

The process began with wrought iron produced by the direct reduction of iron oxide to metal as described above The bloom was broken into small pieces 0520 lb and placed in a clay crucible with pulverized charcoal 110 of the weight of the wrought iron

Despite the military demand for cast iron most civil applications required malleable iron which until then had been made directly in a bloomery The arrival of blast furnaces however opened up an alternative manufacturing route this involved converting cast iron to wrought iron by a process known as fining Pieces of cast iron were placed on a finery hearth on which charcoal was being burned with a

May 11 2019 · Coal was used in the indirect method of making wrought iron from ore instead of the Direct Bloomery method There was great trouble with it as even when coked the sulfur content tended to degrade the iron produced Charcoal is the gold standard for fuel and NOT briquettes Charcoal

Sep 06 2016 · The stratified process produced a blister steel Thin strips of highly refined wrought iron are layered stratified with charcoal mixed with bone leather and wood charcoal in a box that could be sealed to keep air out The box is heated to about 1500 degrees and kept hot for many hours

Wrought Iron Wrought iron is composed primarily of iron with 1 to 2 of added slag the byproduct of iron ore smeltinggenerally a mix of silicon sulfur phosphorous and aluminum oxides During
