Description
Technical field
The present invention relates to metal smelt technical field, particularly to a kind of liquid metal flows accelerator.
Background technology
The mobility of metal refers to the fluid ability of motlten metal, and the quality of metal fluidity, generally with " helical flow
Property sample " length weigh, metal liquid is poured in spiral type sample casting mold, under identical pouring condition, alloy
Mobility is the best, and the sample watered out is the longest.Different types of metal liquid, has different mobility, the stream of metal liquid
Dynamic property is good, and mold-filling capacity is the strongest, is readily available the foundry goods that size is accurate, profile is complete and clear-cut, if Liquid-metal flow
Property bad, will appear from following casting defect: (1) water less than with cold shut, water less than refer to foundry goods incomplete or may profile imperfect,
Or possibility foundry goods is complete, but corner is round and bright, and this defect often occurs at the position away from cast gate and thin-walled, and cold shut is
Referring to penetrate on foundry goods or do not penetrate through, a class defect in rounded shape gap, edge, cold shut occurs at thin-walled more, metal stream converges
At conjunction, Quench position etc.；(2) pore and field trash, the poor fluidity of metal liquid, then viscosity is big, the gas in motlten metal
Floating with field trash inconvenience and discharge, easily forming pore, field trash one class casting defect, pore refers to inner surface relatively light
Sliding, generally circular in cross section, oval hole, the most do not expose cast(ing) surface, field trash refers to exist in foundry goods or on surface
The particle class defect different from parent metal composition, common are sand, slag, oxide, sulfide etc..
As can be seen here, the quality of metal fluidity governs the yield rate of foundry enterprise, and wherein, chemical composition is impact gold
Belong to this quality factor of liquid fluidity, a kind of improve the accelerator of the mobility of liquid metal in melting accordingly, it would be desirable to develop.
Summary of the invention
For solving the problem of above-mentioned existence, it is an object of the invention to provide and plant containing a kind of liquid metal flows promotion
Agent.Described accelerator can be effectively improved the mobility of liquid metal in low smelting heat, reduce pore in production process, incompleteness,
The formation of the defect such as loose, is substantially improved the property indices of foundry goods, improves the yields that enterprise produces, the amount being simultaneously introduced
Few, service efficiency is high, and use cost is low, increases the economic well-being of workers and staff of enterprise.
For reaching above-mentioned purpose, the technical scheme is that
A kind of liquid metal flows accelerator, described accelerator is by ferrosilicon, ferromanganese, ferronickel, bismuth, silicon zirconium inovulant and rare earth

Ferrosilicon is with coke, steel cuttings, quartz or Silicon stone as raw material, and the ferro-silicium made with electric furnace smelting, ferrosilicon is at ferrum
Alloy industry is used as to produce the reducing agent of low carbon ferroalloy.Ferrosilicon adds the inovulant that can make spheroidal graphite cast-iron in cast iron, and energy
Stop carbide to be formed, promote precipitation and the nodularization of graphite, improve cast iron.Element silicon can promote carbon contained in the pig iron to divide
From for graphite-like, can deoxygenate, moreover it is possible to reduce the core of foundry goods, the mobility of molten pig iron can be improved, reduce the amount of contraction of foundry goods,
But siliceous too much, also can make that the pig iron is hardening to become fragile.
Ferromanganese can be used as deoxidizer and alloy addition in steel-making, can improve the casting character of the pig iron and cut performance,
Manganese can also form Manganese monosulfide. with objectionable impurities sulfur, enters slag.
Ferronickel as alloying element additive, can improve bending strength and the hardness of steel, in cast iron in steel industry
Can make its even structure, density improves.
Bismuth adds the Low temperature impact toughness that can improve iron and steel, the beneficially refinement of graphitization form with equal in steel industry
Homogenize, improve stability.
Silicon zirconium inovulant obtains tremendous development in recent years.As silicon system inovulant, silicon content height pregnant effect is good, and section is equal
Even property is good, and thickness case hardness difference is little.Another important element zirconium, reacts the nitride generated and reduces dissolved nitrogen, stop ferrum with nitrogen
Water reversible suction nitrogen, suppresses inoculation fade.Carbide that zirconium a small amount of in molten iron is formed, nitride, as graphite crystallization core, rise
To the most graphited effect.
