Abstract
The invention discloses a method for recycling powdery ferrocolumbium. The method comprises the steps of: 1) collecting powdery ferrocolumbium which is sieved during the crushing of lump ferrocolumbium and has the particle size of less than 5mm; 2) preparing an inclusion, wherein the inclusion consists of a lower shell and an upper shell which are of hemispherical shapes or cylindrical shapes, and the lower shell and the upper shell are made of cold rolled sheet or hot rolled sheet with the thickness of between 0.3 and 0.5mm; and 3) filling 200 to 15,000g of the powdery ferrocolumbium into the inclusion consisting of the lower shell and the upper shell, and then pressing or welding the lower shell and the upper shell together to obtain a ferrocolumbium raw material in steel smelting. The method has the advantages that: firstly, by wrapping the powdery ferrocolumbium in the inclusion, the method can directly use the powdery ferrocolumbium for the steel smelting, does not need a processing procedure of circularly returning the powdery ferrocolumbium to a furnace to be smelted into groups, can greatly reduce production cost, and also avoid the pollution to the environment during the processing of smelting the powdery ferrocolumbium into groups; and secondly, production technology for smelting is optimized through uniform size and standard weight of the powdery ferrocolumbium wrapped by the inclusion, and the powdery ferrocolumbium can be directly charged from a bin through a conveyor belt during charging.
Description
Technical field
The present invention relates to a kind of utilization of powdery ferrocolumbium.
Background technology
Because the ferro-niobium finished product is into blocky, in shattering process, produce a large amount of powdery ferrocolumbiums, because powdery ferrocolumbium can not sink in the molten steel, fly at molten steel surface, cause the recovery rate of niobium element in molten steel low, influence steel product quality, therefore powdery ferrocolumbium can not be directly used in the steel smelting, the existing general practice is: it is agglomerating that powdery ferrocolumbium is gone into the stove melting again, in addition broken again, melting niobium powder need be allocated a certain proportion of auxiliary material in the existing processes, and power consumption reaches about 1500 degree/tons, the niobium powder produces a large amount of CO2 in the agglomerating process of melting, obnoxious flavour and waste residues such as SO2 are bigger to the pollution of environment.The technology that the niobium powder is gone into the stove melting is because of existing the scaling loss of 10-15%, and the content of niobium in the finished product is reduced significantly, and the cost that is recycled into the stove melting is too high.
Summary of the invention
The recoverying and utilizing method that the purpose of this invention is to provide a kind of powdery ferrocolumbium.
The present invention realizes in the following way: a kind of recoverying and utilizing method of powdery ferrocolumbium,
1), is collected in the powdery ferrocolumbium of granularity below 5mm that tails in the block ferro-niobium shattering process;
2), prepare a kind of inclusion, this inclusion is made up of the lower housing and the upper housing of hemispherical or column, the employing thickness of lower housing and upper housing is that cold-reduced sheet or the hot-rolled sheet of 0.3mm-0.5mm made;
3), powdery ferrocolumbium poured into by lower housing and upper housing forms in the inclusion, the amount that pours into powdery ferrocolumbium is 200g-15000g, then with lower housing and upper housing pressing or weld together, promptly becomes the ferro-niobium raw material of steel in smelting.
The present invention has following beneficial effect, the one, by powdery ferrocolumbium is wrapped in the inclusion, can directly powdery ferrocolumbium be used for steel smelts, do not need this manufacturing procedure of the group of being smelted into is melted down in the powdery ferrocolumbium circulation, can reduce production costs greatly, also avoid in the agglomerating course of processing of powdery ferrocolumbium melting staining that environment causes; The 2nd, the powdery ferrocolumbium volume size by inclusion parcel evenly, weight standard has been optimized the technology of the production of smelting, and can directly drop into from feed bin by travelling belt when feeding intake.

Embodiment
A kind of recoverying and utilizing method of powdery ferrocolumbium,
1), is collected in the powdery ferrocolumbium of granularity below 5mm that tails in the block ferro-niobium shattering process;
2), prepare a kind of inclusion, this inclusion is that hemispheric lower housing 1 and upper housing 2 are formed, the employing thickness of lower housing 1 and upper housing 2 is that the cold-reduced sheet or the hot-rolled sheet of 0.4mm thickness made, and parcel limit 3 is arranged on lower housing 1, and limit 4 is wrapped on upper housing 2;
3), powdery ferrocolumbium is poured into by lower housing 1 and upper housing 2 and form in the inclusion, the amount that pours into powdery ferrocolumbium 5 is 1300g, with impact style the parcel limit 3 on the lower housing 1 is superscribed the limit 4 that is wrapped on the housing 2,, promptly become the ferro-niobium raw material in the steel smelting as Fig. 1, Fig. 2, shown in Figure 3.
