Abstract
The invention discloses a micro-carbon Al-Mn-Ti-Fe killer alloy and preparing method, which comprises the following parts: 30-60% Al, 5-10% Mn, 1-10% Ti, not more than 0.08% C and Fe. The making method comprises the following steps: allocating metal aluminium, metal manganese and superior waste steel; adding in the frequent electric furnace; fusing; deslagging; stewing; casting.
Description
Technical field
The present invention relates to a kind of alloy.Be particularly useful for micro-carbon-aluminium-manganese, iron alloy of steel-deoxidizing and alloying and preparation method thereof.
Background technology
As far back as 20th century the eighties, Anshan iron and steel plant had once been developed " aluminum-manganese-iron alloy ", owing to be subjected to the common influence of carbon content in waste steel quality and the ferromanganese at that time, alloy product is efflorescence soon, has lost popularizing value.
The present invention is directed to this technical disadvantages,, found the true cause of alloy pulverization finally, and determined the limit value of carbon content, thereby just can obtain non-chalking micro-carbon-aluminium-manganese, iron alloy through exploring and repetition test.
Summary of the invention
The present invention is achieved in that its alloy composition (weight percent) is:
Aluminium: 30-60,
Manganese: 5-25,
Carbon :≤0.08,
Iron: surplus.
The effect of aluminium among the present invention: 1, the steel to general applications carries out deoxidation; 2, to the steel that requires sour molten aluminium as alloying constituent, for example automobile is defined as 0.02-0.07% with acid-soluble aluminum content GB in the 08 aluminum steel steel; 3, crystal grain thinning.Acting in the aluminum base alloy of carbon is most important, carbon content has determined its efflorescence and not efflorescence in the alloy, and atomizing speed issue, when carbon content in the alloy is limited≤0.08% value, the lattice of aluminium is not destroyed, and in this case, can obtain non-chalking alloy, when carbon content was higher than 0.08%, the high more efflorescence speed of content was fast more.Facts have proved the equal onrelevants of element such as alloy pulverization and institute's added elements manganese, silicon, titanium, barium, magnesium, calcium.The effect 1 of manganese in the alloy, increase alloy proportion make alloy with molten steel be arranged enough action time in adding ladle, thereby improve the recovery rate of aluminium; 2, during manganese content height (content＞10%), can play the effect of alloying.
Micro-carbon-aluminium-manganese, iron alloy its preparation method:
With feed metal aluminium, manganese metal (or low carbon ferromanganese or mid-carbon fe-mn) and high-quality steel scrap (low-carbon (LC), low-phosphorous, low silicon, low-sulfur), according to customer requirements by the calculation result batching, successively 2/3 aluminium-1/2 steel scrap-manganese metal-1/2 steel scrap-1/3 metallic aluminium is added in the line frequency furnace, after fusing, slagging-off, calmness, come out of the stove, cast blocky micro-carbon-aluminium-manganese, iron alloy.Above-mentioned raw materials used, guarantee carbon content in the finished product alloy≤0.08% in principle, in this case, can suitably select mid-carbon fe-mn, low carbon ferromanganese and manganese metal, purpose is to guarantee not efflorescence of alloy.
Embodiment:
With 59 kilograms of metallic aluminiums, 7.5 kilograms of manganese metals, 43 kilograms of steel scraps, after the batching, successively 2/3 metallic aluminium-1/2 steel scrap-manganese metal-1/2-steel scrap-1/3 metallic aluminium is added in the line frequency furnace, through fusing, come out of the stove after slagging-off, the calmness, cast blocky micro-carbon-aluminium-manganese, iron alloy.Its chemical ingredients for (weight percent) is:
Aluminium: 57,
Manganese: 7.0,
Carbon: 0.021,
Phosphorus: 0.010,
Sulphur: 0.004,
Silicon: 0.10,
Iron: surplus.
In converter, the test steel grade is SS400, demarcates deoxidation effect in the process of the test with this alloy, is 25%. to reach standard-required through the recovery rate of LF stove sampling Als 0.043% average aluminium.
The advantage of this alloy is:
1, the more little carbon ferroaluminium of proportion slightly up to (4.8～5.5g/cm3).
2, belong to the i.e. four low high cleanliness alloys of low-carbon (LC), low silicon, low-phosphorous, low-sulfur.This alloy is not only applicable to the deoxidation of ordinary steel, more is applicable to various elaboration steel, the deoxidation and the alloying of special-purpose steel and Ultra-low carbon Clean Steel.
Claims (2)
1, be used for the micro-carbon-aluminium-manganese, iron alloy and preparation method thereof of steel-deoxidizing and alloying, it is characterized in that: chemical ingredients (weight percent):
Aluminium: 30-60
Manganese: 5-25
Carbon :≤0.08,
Iron: surplus.
2, by the described micro-carbon-aluminium-manganese, alloy that is used for steel-deoxidizing and alloying of claim, its preparation method, be characterised in that: with feed metal aluminium, manganese metal (or low Carbon Manganese aluminium or mid-carbon fe-mn) and high-quality steel scrap (low-carbon (LC), low silicon, low-phosphorous, low-sulfur) are prepared burden by the mark result according to customer requirements, successively 2/3 metallic aluminium-1/2 steel scrap-manganese metal-1/2 steel scrap, 1/3 metallic aluminium is added in the main frequency furnace, after fusing, slagging-off, calmness, come out of the stove, cast blocky micro-carbon-aluminium-manganese, iron alloy.
