Abstract
The present invention discloses an Al-Mn-Ti-Fe alloy used for deoxidization and alloying for steel making, which comprises 40 to 60 wt% of Al, 5 to 10 wt% of Mn, 0.5 to 8 wt% of Ti and Fe as the rest. When the alloy is used for smelting common titaniferous low-alloy steel or microalloy steel, the present invention has the advantages of proper manganese content and favorable effect of deoxidation and desulfurization.
Description
The present invention relates to the steely iron alloy, particularly a kind of aluminium-manganese-titanium-magnesium-iron alloy that is used for deoxidation in steel making and alloying.
Smelt low alloy steel and micro-alloyed steel, once finish for making deoxidation in steel making and alloying, in recent years, people made polynary iron alloy use with steel making deoxidant and alloying composition.A kind of aluminum-manganese-titanium-iron alloy of this purposes was once disclosed as the CN1198473A Chinese patent application.The chemical ingredients of this alloy (weight ratio) is Al5-40%, Mn20-70%, and Ti1-15%, surplus is Te.Find in actual use, this clock iron alloy, inapplicable to smelting ordinary low-alloy steel.Mainly be that wherein manganese content is too high, cause that the content of manganese transfinites in the steel, the mechanical property of steel is become fragile; In addition, the content height of manganese, must cause the content of aluminium to reduce, and the main component of a desoxydatoin is an aluminium, so its deoxidation effect descends.Another shortcoming of this iron alloy is that sweetening effectiveness is poor, and the content of sulphur is higher in the steel, and generally at 0.04-0.05%, and sulphur is harmful element in steel.
The objective of the invention is to be improved at above-mentioned prior art, provide a kind of manganese content suitable, deoxidation effect is good, has the aluminium-manganese-titanium-magnesium-iron alloy of sweetening effectiveness preferably simultaneously again.
Aluminium-manganese-titanium-magnesium-iron alloy provided by the invention, its chemical ingredients (weight ratio) is: Al40-60%, Mn5-10%, Ti0.5-8%, Mg1-8%, surplus is Fe.
The content of manganese is reduced to and is no more than 10% among the present invention, suits as smelting ordinary low-alloy steel, can not make that manganese transfinites in the steel.Because the content of aluminium has improved the also corresponding raising of its deoxidation effect.Titanium can increase the toughness of steel as the alloying constituent of steel.Owing to contain a certain amount of magnesium in this iron alloy, and magnesium is good sweetening agent, so its sweetening effectiveness is better.But Mg content should not surpass 8%, because of too much magnesium, can form bubble in molten steel, causes the molten steel boiling, and magnesium also can go out with bubble is contrary, and is ineffective.
Make to smelt the deoxidizing alloy of ordinary low-alloy steel with this iron alloy, oxygen content in steel can reach 30ppm, and sulphur content can reach below 0.04%.
Aluminium-manganese-titanium-magnesium-iron alloy of the present invention, can adopt two kinds of processing method preparations:
A kind of method is to be raw material with aluminium ingot, magnesium ingot, ferrotianium, ferromanganese and steel scrap, by calculating good proportion ingredient in advance, places in the main frequency furnace, makes the aluminium-manganese-titanium-magnesium-iron alloy that meets the composition requirement through fusing.
Another kind method is with raw materials such as bauxitic clay, manganese ore, magnesium ore, steel cuttings, feed intake by calculating good proportioning in advance, make reductive agent with coal or coke, be smelted into the liquid that contains aluminium manganese magnesium iron with the mining and metallurgy stove after, add a certain amount of ferrotianium again, be smelted into the aluminium-manganese-titanium-magnesium-iron alloy that meets the composition requirement.Though this method raw materials cost is lower, power consumption is big, and total cost of production and first method are equally matched.
Embodiment
Aluminium ingot, (height) ferromanganese, magnesium ingot, the ferrotianium that will meet GB are pressed 52% (weight percent respectively, down with), 11%, 6%, 7%, surplus is the ratio batching of steel scrap, place in the main frequency furnace, heat up, fusing fully was melt into liquid state through 60 minutes, came out of the stove, pour into piece, promptly make composition and be Al50%, Mn7%, Ti3%, Mg5%, surplus is the aluminium-manganese-titanium-magnesium-iron alloy of Te.
Claims (1)
1, a kind of aluminium-manganese-titanium-magnesium-iron alloy that is used for deoxidation in steel making and alloying is characterized in that: its chemical ingredients (weight ratio) is: Al40-60%, and Mn5-10%, Ti0.5-8%, Mg1-8%, surplus is Fe.
