Abstract
A metallurgical furnace charge, steel grain briquetting, is prepared from the steel slag discharged from iron and steel plant through magnetic separation to obtain steel grains, mixing with raw iron grains (5-20 wt.%), stirring, and die pressing. The invention adopts normal temperature solidification, has simple production process and is suitable for forming iron steel particles, raw iron particles and cast iron particles.
Description
The present invention relates to a kind of furnace refractory, refer to a kind of production steel particles briquetting that from iron and steel slag small-particle, reclaims especially.
The iron and steel slag is to smelt the waste of discharging in the production, and only one day quantity discharged of Xinyu Iron and Steel Works can reach more than 200 tons.A large amount of iron and steel slag dischargings, land occupation, year in and year out, pile up like a mountain, and soil property is caused deterioration, pollutes surrounding enviroment.Changing waste into valuables how is not wasted the iron and steel small-particle in the waste residue of Steel Plant's discharging, and resource is fully used.What adopt usually on the general industry is sintering process, and weak point is that this technological process power consumption is high, and atmospheric pollution is serious, brings a large amount of impurity into to smelting, and grade of sinter is low, causes coke ratio to rise significantly.
In order to solve above-mentioned deficiency, purpose of the present invention provides a kind of and does not consume energy, pollution-free briquetting iron.Widen the furnace refractory source, and the iron and steel slags of a large amount of dischargings of energy industrial treatment Steel Plant, reduce resources loss, improve the business economic benefit.
The object of the present invention is achieved like this:
Adopt conventional magnetic separation process, the iron and steel grain that obtains will be reclaimed, the about 5-20% of pig iron grain through breaking and Dusting, under the effect of additive (adopting water to make solvent), mix through stirrer, pour mould into and suppress, solidify at normal temperatures, water spray, maintenance, obtain a kind of furnace refractory---steel particles briquetting iron finished product.The additive main ingredient that the present invention uses is made up of ferric ammonium citrate, hydrochloric acid, sodium chloride, iron trichloride etc.The used component dosage of additive is very little, accounts for the thousandth or about two of briquetting iron weight.
Effect of the present invention:
1, the present invention adopts ambient cure, the production technique simple possible, and raw material resources are plentiful, waste reclaimation, product cost is low.
2, widen the furnace refractory source, briquetting iron can be used for cupola furnace, large, medium and small blast furnace and converter.
3, briquetting iron grade is up to more than 70%, than agglomerate good permeability, and the intensity height, lumpiness is even, does not need reduction, and coke ratio is low.
4, used binder amount is little, and its component is to smelting no harm.
Embodiment:
The iron and steel slag of Steel Plant's discharging is sent into one-level magnetic separation in the belt-type magnetic separator, at this moment can obtain the iron and steel particle of content about about 40%, enter in the hammer mill broken apart, enter secondary magnetic separation again, reach obtain content at iron and steel grain more than 70%, take by weighing its 1000 kilograms, 150 kilograms of pig iron grains, the agent component is tied in adding of 1000 gram weight, send into uniform mixing in the stirrer, the mould of falling people is suppressed moulding, solidifies at normal temperatures 2-3 days, water spray, about 10 day time of maintenance, the briquetting finished product can be thrown stove and smelt.
The present invention also is applicable to the moulding of iron and steel end, iron and steel bits.
Claims (2)
1, a kind of furnace refractory---steel particles briquetting mainly is made up of steel grit, pig iron grain, additive, and it forms weight ratio is 1: 0.05-0.2: 0.001-0.002.
2, steel particles briquetting according to claim 1, wherein said additive main ingredient is: ferric ammonium citrate, hydrochloric acid, sodium-chlor, iron trichloride or mixture.
