Abstract
The present invention uses corundum slag and phosphate ore as raw material, addes fusing agent and adopts the metallurgical blast furnace and conventional method to smelt. Compared with the existent technologies, the advantages of said method are simple operation, easy control, low productive cost, and full utilizing the industrial waste slags. The productive cost is lowered by 20%-30% than that of the traditional Technologies and the practical value is very great.
Description
The invention belongs to a kind of method of producing kakoxene with iron slag.
Traditional ferrophosphorus production method is to adopt the melting and obtain ferrophosphorus in electric furnace or blast furnace of iron or iron ore and Rock Phosphate (72Min BPL), and this Technology difficulty is big, and the production cost height.And the corundum slag is generally all outwelled as waste residue as a kind of industrial residue.
The objective of the invention is to: a kind of method of utilizing industrial residue to produce the ferrophosphorus product is provided, thereby reduces product cost greatly, and made full use of industrial residue again, turn waste into wealth.
The present invention constitutes like this: it is to be raw material with corundum slag, Rock Phosphate (72Min BPL), adds flux, adopts the metallurgy high temperature stove to smelt with conventional smelting process.
The present invention compared with prior art, have simple to operate, be easy to control, production cost is low, has made full use of advantages such as industrial residue, its production cost reduces by 20%～30% than traditional technology, has great practical value.
Embodiments of the invention 1: adopt the melting of miniaturization iron furnace, main raw material composition (%): corundum slag Fe72.1, Si15.6, Al5.8, Ti4.2, Po7; Silica SiO298.6, when furnace temperature rises to more than 1400 ℃, begin to feed in raw material, its order and batch of material are: 10 kilograms in coke, 10 kilograms of phosphorus ores, 5 kilograms of corundum slags, 4 kilograms in silica, reinforced 10 batches altogether, 45.3 kilograms of output ferrophosphorus, ferrophosphorus composition (%): P22.8, Si2.3, C0.9, S0.2, Mn0.1, phosphorous recovery: 76.3%.
Embodiment 2: adopt crucible oven to handle, with corundum slag 200 grams, Rock Phosphate (72Min BPL) 400 grams, silica 120 grams, clay 80 grams, to expect to put into plumbago crucible behind the mixing, in 1450 ℃ of reactions 2 hours, come out of the stove after cooling, slag iron separate, get ferrophosphorus 168.6 grams, ferrophosphorus composition (%): P22.3, Si0.5, C1.0, S0.1, Mn0.05, phosphorous recovery: 88.06%.
Claims (1)
1, a kind of method with preparing ferro-phosphorus from corundum slag is characterized in that: it is to be raw material with corundum slag, Rock Phosphate (72Min BPL), adds flux, adopts the metallurgy high temperature stove to smelt with conventional smelting process.
