Abstract
The present invention discloses a composite manganese base deoxidized alloy. It is made up by using metal aluminium, magnesium, ferromanganese, silicon-calcium-barium and adhesive as raw material through the processes of pulverizing raw material, stirring, press-forming and drying, etc. Said invention overcomes the defects of smelting method which can produce non-uniform molten alloy and lots of slag spot, and can make its product have higher cleaness, and can ensure alloy density, and can raise steel material quality and reduce steel-smelting cost.
Description
Technical field
The present invention relates to a kind of alloy material, relate to a kind of compound manganese base deoxygenated alloy specifically.
Background technology
At present, relate to for smelting industry that to make steel the deoxygenated alloy of usefulness of a great variety, but these alloys are to be main deoxidation and so on aluminium mostly.This class deoxygenated alloy proportion is less, thereby has influenced the direct reaction with molten steel, deoxidation effect instability.Because its deoxidation products in participating in deoxidation process is to be present in the molten steel with floss, ascent rate is very slow, has influenced the cleanliness factor of steel on the one hand; On the other hand,, cause the tundish dross easily, cause and stop in the continuous casting to water, influence extraordinary production if add-on is excessive.Therefore, need this technology is further improved.
Summary of the invention
The purpose of this invention is to provide a kind of compound manganese base deoxygenated alloy, be with the bigger ferromanganese of density as matrix, make it have that density is big, lumpiness is even, molten speed is fast, cleaning molten steel, raising steel product quality, reduce the result of use of steel-making cost.
For achieving the above object, alloy raw material that technical scheme of the present invention adopted and content (is unit with the weight percent):
C:1-7%, Mn:20-55%, Si:3-12%, Al:5-20%, Ca+Ba+Mg: P 〉=5%: S≤0.20%: moisture content≤0.08% :≤0.50%, surplus is Fe.
Preferred feedstock ratio range of the present invention:
C:3-6%, Mn:35-45%, Si:5-10%, Al:12-16%, Ca+Ba+Mg: P 〉=5%: S≤0.20%: moisture content≤0.08% :≤0.50%, surplus is Fe.
Optimum material proportion scope of the present invention:
C:4.72%, Mn:41.3%, Si:7.49%, Al:14.71%, Ca+Ba+Mg:5.94%, P:0.153%, S: moisture content≤0.059% :≤0.41%, surplus is Fe.
Its processing step:
1, choosing high-quality ferromanganese, metallic aluminium, magnesium, silico-calcium barium in proportion is raw material for standby;
2, add binding agent after above-mentioned raw materials is crushed to the 10-50 order, it is standby fully to be mixed;
3, the material after above-mentioned being mixed is poured into compression moulding in the mould of pressing machine, drying to 180 ℃ is finished product again.
Characteristics of the present invention are: compound manganese base deoxygenated alloy is to adopt physics synthetic mode, has overcome shortcomings such as smelting process alloy melting inequality, slag inclusion are many, and the cleanliness factor that makes its product more.Its effect be with ferromanganese as matrix, guaranteed the density of alloy, alloy is directly contacted with molten steel, satisfied the requirement of molten steel degree of depth deoxidation greatly; Alkaline-earth metal Ca, Ba in this alloy, Mg are reductors, after these elements are added by a certain percentage, can improve inclusion morphology in the molten steel, help the floating upward quickly of inclusion, thereby have played the effect of strong deoxidation and cleaning molten steel; This alloy product substitutes aluminium base deoxygenated alloy in addition, can reduce steel-making cost.
