Description
Technical field
The present invention relates to a kind of zinc alloy casting technique, belong to Alloys Casting field.
Background technology
Cast zinc alloy is that ZnA1 mono-Cu-Mn is quaternary alloy, lower owing to thering is fusing point, the advantages such as good mechanical performance and easily plating, be widely used as all kinds of diecast parts, China's Delta of the Pearl River one reaches 2O ten thousand t/a～300,000 t/a with the consumption of zinc die casting alloys at present, mainly for the production of toy and the auto parts and components etc. of various class, although the quality standard of zinc die casting alloys is gradually unified, its composition requires roughly the same, but there is very big-difference in the effect that different types of diecasting alloys use, some alloy reflections are good, what have is just poor, this is relevant with production technology, pass through various influence factor comparisons herein, the production technology that exploration makes new advances, and prepare die case zinc product and compare.
Gas burner production technology is used high purity zinc liquid as alloy production raw material, has avoided melting because of mixer the increasing iron phenomenon occurring with gas burner.For in the focus on ± 0.3Kg scope of controlling alloy pig, adopt graphite cone to control flow techniques.This technological process is simple, production cost is low, but it is low that the defect of coal gas steam stove is direct yield, mechanical agitation makes the homogeneity of ingredients of aluminium alloy poor, electric furnace production technology, zinc is melted and remove slag with high-power power frequency cored stove, then zinc liquid is flowed out from stove tapping, person who lives in exile's coreless furnace again, by alloying element material melting and form aluminium alloy, utilize tipple that aluminium alloy is poured out, flow in holding furnace by chute, scoop out by machinery spoon again, then inject in zinc mould, the defect of this technique maximum is that the scum silica frost producing in the process of tumbling from coreless furnace to resistance furnace is more.And the form of quality of the vibration alloy ingot surface of creeping of linear ingot casting is unfavorable.Energy consumption is larger simultaneously.
