Description

A kind of iron powder compound stalk forming method
Technical field
The present invention relates to technical field of ferrous metallurgy, be specifically related to a kind of iron powder compound stalk forming method.
Background technology
Steel are the metal materials being prepared from after the PROCESS FOR TREATMENT such as high-temperature heating, de-carbon for raw material with the pig iron. In pig iron steelmaking process, need that first iron powder is carried out briquetting and process the agglomerate making definite shape and intensity, send the most again Steel-making preparation is carried out in entering high temperature smelting furnace.Iron powder block transport during, iron powder agglomerate need to experience carrying, topple over, high temperature Heat, transport, the processing procedure such as cooling, the iron powder agglomerate therefore suppressed should have good shape and intensity.
At present, the method cycle length of iron powder briquetting technology of preparing of being correlated with in market employing, complex procedures, and cost is relatively Height, is unsuitable for large-scale industrial production.
Summary of the invention
It is an object of the invention to overcome the defect of prior art, it is provided that a kind of low cost, low technical require, the ferrum of high intensity Briquetting forming technique.
Specifically, the invention provides a kind of iron powder compound stalk forming method, said method comprising the steps of: take ferrum Powder, adds mix and blend after molasses, adds slaked lime powder mix and blend, compressing,.
Iron powder of the present invention is by refining gained in copper ashes.In order to improve molding effect, described iron powder should be at grinding Reason, it is preferably dimensioned to be 100~200 mesh.
The addition of described molasses is the 3~10% of iron powder quality.Described molasses be preferably 10~30% molasses water-soluble Liquid.
The addition of described slaked lime is the 2~5% of iron powder quality.
In order to improve the mixed effect of raw material, to guarantee to suppress the performance of gained molding iron block, described addition molasses prognosis The mix and blend time is 5~20 minutes;After described addition slaked lime, the mix and blend time is 5~20 minutes.
Described compressing preferably employing 400 tons of forcing presses and suppress, the press time is 7~20 seconds.
The present invention protects the product using described method compressing further.
The intensity of described product can use the conventional method of this area to carry out.Such as: ball block is fallen in water at 1 meter of height Mud ground face, record profile keeps the number of times that complete ball block can be dropped.
The iron powder compound stalk forming method that the present invention provides has the advantage that the method step is simple and convenient to operate, to setting Low for requiring;Raw material sources are extensive, cheap;Additive does not contains Si and compound thereof, controls the quantity of slag, fall in being conducive to smelting Low energy consumption;Preparation process environmental protection, nontoxic, environment is had friendly, is suitable to large-scale industrial production.
Detailed description of the invention
Following example are used for illustrating the present invention, but are not limited to the scope of the present invention.
Embodiment 1
Take the iron powder of a certain amount of a size of 100 mesh, be added thereto to the molasses solubles of iron powder quality 3%, wherein molasses The concentration of solution is 30%, subsequently iron powder and molasses solubles is sufficiently mixed stirring 5 minutes;After having stirred, to this mixture Material adds 2% slaked lime powder of iron powder quality, continues mix and blend 5 minutes;Take the material that above-mentioned mixing completes and put into 400 tons Lasting pressurize 7 seconds in forcing press, discharging,.
Being thrown at 1 meter of height by the present embodiment gained iron powder ball block, drop resistant intensity reaches more than twice.
Embodiment 2
Take the iron powder of a certain amount of a size of 200 mesh, be added thereto to account for the molasses solubles of iron powder quality 5%, wherein sugar The concentration of honey solution is 28%, subsequently iron powder and molasses solubles is sufficiently mixed stirring 7 minutes;After having stirred, to this mixing Material adds 4% slaked lime powder of iron powder quality, continues mix and blend 10 minutes;Take the material that above-mentioned mixing completes to put into Lasting pressurize 10 seconds in 400 tons of forcing presses, discharging,.
Being thrown at 1 meter of height by the present embodiment gained iron powder ball block, drop resistant intensity reaches more than twice.
Embodiment 3
Take the iron powder of a certain amount of a size of 100 mesh, be added thereto to the molasses solubles of iron powder quality 10%, wherein molasses The concentration of solution is 19%, subsequently iron powder and molasses solubles is sufficiently mixed stirring 10 minutes;After having stirred, to this mixture Material adds 3% slaked lime powder of iron powder quality, continues mix and blend 15 minutes;Take the material that above-mentioned mixing completes and put into 400 Lasting pressurize 15 seconds in ton forcing press, discharging,.
Being thrown at 1 meter of height by the present embodiment gained iron powder ball block, drop resistant intensity reaches more than twice.
Although, used general explanation, detailed description of the invention and test, the present invention made detailed retouching Stating, but on the basis of the present invention, can make some modifications or improvements it, this is apparent to those skilled in the art 's.Therefore, these modifications or improvements without departing from theon the basis of the spirit of the present invention, belong to claimed Scope.
