Abstract

The invention discloses a kind of spheroidal graphite cast-iron high-performance nodulizers, it includes containing following weight percents component: 6-12 parts of magnesia, 4-15 parts of calcium chloride, 3-5 parts of yttrium powder, 1-3 parts of nickel powder, 5-10 parts of pure magnesium ingot, 15-30 parts of nanometer silicon carbide, 5-10 parts of rare earth ferrosilicon alloy, 1-10 parts of iron powder, 6-9 parts of Si-Mg alloy and 2-5 parts of rare earth element, remaining is phenolic resin solvent.Nodulizing agent for nodular cast iron additional amount of the invention is related with the surplus of magnesium in iron liquid, and the anti-ageing ability of moving back is stronger than magnesium, is not in cementite when high-carbon breeds good.

Description

A kind of spheroidal graphite cast-iron high-performance nodulizer
Technical field
The present invention relates to a kind of spheroidal graphite cast-iron high-performance nodulizers.
Background technique
Spheroidal graphite cast-iron is a kind of grey cast-iron with excellent mechanical properties.Generally before casting, it is added in iron liquid A small amount of nodulizer and inovulant, form globular graphite after making molten steel solidification.The intensity and toughness of such cast iron are higher than other cast irons, Cast steel and malleable cast iron can be replaced to be widely applied in machine building industry sometimes.
The most important factor for influencing Nodular cast iron material performance is the control technology of spheroidising quality, and influences at nodularization Managing one of most important factor of quality again is the quality of nodulizer.
Current spheriodization process thereof mainly pours method, Gai Bao pours method and Feed aluminum wire, wherein pours Fa Hegai packet and pours Method accounts for 80% or so of magnesium iron total output.Pouring Fa Hegai packet and pouring method all is nodulizer to be placed in advance processing packet bottom, so It is poured in processing packet with the iron liquid that chemical component and temperature all meet technique requirement afterwards, brings it about metamorphic reaction, promote to be formed Spheroidal graphite cast-iron iron liquid.
Summary of the invention
The object of the invention is that providing a kind of high-performance nodulizer to solve the above-mentioned problems.
To achieve the goals above, the present invention is achieved by the following technical solutions: a kind of spheroidal graphite cast-iron high-performance Nodulizer comprising contain following weight percents component: 6-12 parts of magnesia, 4-15 parts of calcium chloride, 3-5 parts of yttrium powder, nickel powder 1-3 parts, 5-10 parts of pure magnesium ingot, 15-30 parts of nanometer silicon carbide, 5-10 parts of rare earth ferrosilicon alloy, 1-10 parts of iron powder, Si-Mg alloy 6-9 parts and 2-5 parts of rare earth element, remaining is phenolic resin solvent.
Further, a kind of spheroidal graphite cast-iron high-performance nodulizer comprising contain following weight percents component: oxidation 8-10 parts of magnesium, 8-13 parts of calcium chloride, 3-5 parts of yttrium powder, 1-3 parts of nickel powder, 6-8 parts of pure magnesium ingot, 20-28 parts of nanometer silicon carbide, rare earth 6-8 parts of Antaciron, 2-6 parts of iron powder, 7-8 parts of Si-Mg alloy and 3-4 parts of rare earth element, remaining is phenolic resin solvent.
Further, a kind of spheroidal graphite cast-iron high-performance nodulizer comprising contain following weight percents component: oxidation 9 parts of magnesium, 9 parts of calcium chloride, 4 parts of yttrium powder, 2 parts of nickel powder, 7 parts of pure magnesium ingot, 25 parts of nanometer silicon carbide, 7 parts of rare earth ferrosilicon alloy, iron powder 4 parts, 8 parts of Si-Mg alloy and 3 parts of rare earth element, remaining is phenolic resin solvent.
Particularly, the rare earth element is one of tungsten, antimony, tin, titanium, vanadium or a variety of mixing
In summary the invention has the following advantages: Nodulizing agent for nodular cast iron additional amount of the invention and magnesium in iron liquid Surplus is related, and the anti-ageing ability of moving back is stronger than magnesium, is not in cementite when high-carbon breeds good.
