Abstract
The invention discloses a steelmaking refining agent bearing zirconium oxide and a preparation method thereof. The steelmaking refining agent is composed of the following materials, by weight, 35-37 parts of calcium oxide, 22-25 parts of river sand, 13-15 parts of iron ore tailings, 9-11 parts of the zirconium oxide, 12-14 parts of wollastonite powder, 9-11 parts of calcium sulfate, 7-9 parts of aluminum oxide, 10-12 parts of cullet and 15-17 parts of ceramsite. According to the steelmaking refining agent, the calcium oxide, the river sand and the iron ore tailings are the main raw materials, the zirconium oxide, the wollastonite powder, the calcium sulfate, the cullet and the ceramsite are added, the waste is turned into wealth, adsorptive properties of the refining agent are utilized fully, the refining agent is good in desulfuration and dephosphorization effect, the phenomenon of rephosphorization is reduced, at the same time, the content of the calcium oxide is high, and the production cost is reduced.
Description
Technical field
The present invention relates to steelmaking technical field, steel-making refining agent being specifically related to a kind of loaded zirconia and preparation method thereof.
Background technology
At present, more and more higher requirement is proposed to STEELMAKING PRODUCTION rate and cost and steel products quality, for being applicable to this requirement, external refining particularly ladle furnace refining becomes the important production process in modern refining flow process, be used widely at each smelter, a main metallurgical function of ladle furnace refining utilizes refining agent to carry out refining to molten steel, to reach the object reducing steel water oxygen, sulphur and inclusion content, improve the performance of steel, refining agent kind is a lot.
Summary of the invention
Steel-making refining agent that the object of the present invention is to provide a kind of loaded zirconia and preparation method thereof, zirconium white, wollastonite powder, aluminium sesquioxide and glass cullet and haydite is added in refining agent formula of the present invention, take full advantage of its absorption property, refining agent desulfurization, dephosphorization effect are good, and cost is low.
The present invention adopts following technical scheme to achieve these goals:
The steel-making refining agent of loaded zirconia, the weight part of its constitutive material is: calcium oxide 35-37, river sand 22-25, iron sand tailing 13-15, zirconium white 9-11, wollastonite powder 12-14, calcium sulfate 9-11, aluminium sesquioxide 7-9 and glass cullet 10-12 and haydite 15-17.
The steel-making refining agent of loaded zirconia, the weight part of its constitutive material is: calcium oxide 36, river sand 23, iron sand tailing 14, zirconium white 10, wollastonite powder 13, calcium sulfate 10, aluminium sesquioxide 8 and glass cullet 11 and haydite 16.
The preparation method of the steel-making refining agent of loaded zirconia, comprises the following steps:
(1) broken: the particle each raw material is broken into respectively with crusher;
(2) mix: each raw material good for fragmentation is pressed recipe requirements mixing, and mix with ball mill;
(3) sieve: with 120 eye mesh screens, the raw material mixed is sieved;
(4) dry: put by the raw material after sieving and toast in an oven, remove moisture, storing temperature is 80-100 DEG C, according to the volatilization extent control baking time of moisture.
Beneficial effect of the present invention:
The present invention with calcium oxide, river sand and iron sand tailing for main raw material, wherein with the addition of zirconium white, wollastonite powder, aluminium sesquioxide and glass cullet and haydite, turn waste into wealth, take full advantage of its absorption property, refining agent desulfurization, dephosphorization effect are good, decrease rephosphorization phenomenon, simultaneously, wherein calcium oxide content is high, reduces production cost.

Below in conjunction with the preparation embodiment of above-mentioned refining agent, specifically describe the using method of steel-making refining agent of the present invention:
Adopt the refining agent described in embodiment 1, addition method routinely, a point secondary adds, and test molten steel is surrounded by No. 1-5, and desulfurization, sulphur phosphorus effect are as following table:
No. 1: molten steel condition: S 0.033%, P 0.165%; Desulfurization degree 62%, dephosphorization rate 54%;
No. 2: molten steel condition: S 0.037%, P 0.167%; Desulfurization degree 59%, dephosphorization rate 52%;
No. 3: molten steel condition: S 0.039%, P 0.172%; Desulfurization degree 57%, dephosphorization rate 48%;
No. 4: molten steel condition: S 0.041%, P 0.169%; Desulfurization degree 55%, dephosphorization rate 51%;
No. 5: molten steel condition: S 0.043%, P 0.166%; Desulfurization degree 54%, dephosphorization rate 53%.
Illustrate that refining agent of the present invention has higher desulfurization, sulphur phosphorus rate, and good stability, cost is lower, can substantially meet steel mill's technical requirements.
