At present, STEELMAKING PRODUCTION rate and cost and steel products quality have been proposed to more and more higher requirement, 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 is to utilize refining agent to carry out refining to molten steel, to reach the object that reduces steel water oxygen, sulphur and inclusion content, the performance that improves steel, refining agent kind is a lot.
Summary of the invention
The object of the present invention is to provide a kind of steel-making refining agent that contains bamboo charcoal and preparation method thereof, bamboo charcoal, fluorite slag, neatly stone flour and modified Nano powder in refining agent formula of the present invention, are increased, 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 that contains bamboo charcoal, the weight part of its constitutive material is: Calcium Fluoride (Fluorspan) 28-32, ferric oxide 18-22, norbide 17-19, Iron-ore Slag 15-17, bamboo charcoal 10-15, fluorite slag 6-8, neatly stone flour 20-25 and modified Nano powder 3-5.
The steel-making refining agent that contains bamboo charcoal, the weight part of its constitutive material is: Calcium Fluoride (Fluorspan) 30, ferric oxide 20, norbide 18, Iron-ore Slag 16, bamboo charcoal 12, fluorite slag 7, neatly stone flour 22 and modified Nano powder 4.
The preparation method of the steel-making refining agent that contains bamboo charcoal, comprises the following steps:
(1) fragmentation: each raw material is broken respectively with crusher;
(2) mix: each raw material good fragmentation, by formula requirement mixing, and is mixed with ball mill;
(3) sieve: the raw material mixing is sieved with 150 eye mesh screens;
(4) dry: the raw material after sieving is placed in baking oven and is toasted, remove moisture, storing temperature is 90-120 DEG C, according to the volatilization extent control baking time of moisture.
The preparation method of described modified Nano powder is as follows: sepiolite powder is melted at temperature 1600-1700 DEG C, add the plant ash agitating of the iron powder, the 1-2% that are equivalent to its weight 2-4% even, pour in cold water, dry, be ground into powder.
Beneficial effect of the present invention:
The present invention is taking Calcium Fluoride (Fluorspan) and ferric oxide as main raw material, bamboo charcoal, fluorite slag, neatly stone flour and modified Nano powder are wherein added, turn waste into wealth, take full advantage of its absorption property, refining agent desulfurization, dephosphorization effect are good, have reduced rephosphorization phenomenon, simultaneously, wherein Calcium Fluoride Content is high, has reduced production cost.
Embodiment
Embodiment 1: the steel-making refining agent that contains bamboo charcoal, the weight part (kg) of its constitutive material is: Calcium Fluoride (Fluorspan) 30, ferric oxide 20, norbide 18, Iron-ore Slag 16, bamboo charcoal 12, fluorite slag 7, neatly stone flour 22 and modified Nano powder 4.
The preparation method of the steel-making refining agent that contains bamboo charcoal, comprises the following steps:
