Abstract
The present invention discloses a non-magnetic alloy counterbalance for compressor. It is made up by using iron, carbon, manganese, aluminium and vanadium as raw material through casting process. Its raw material composition includes (by wt%) 16.00-30.00% of manganese, 0.06-0.30% of carbon, 0.50-2.50% of aluminium, 0.04-0.10% of vanadium and the rest is iron and unavoidable trace impurity.
Description
Technical field
The present invention relates to metallurgy, field of mechanical technique, specifically a kind of non-magnetic alloy balance block for compressor use.
Background technique
Equilibrium block is the vitals of compressor, and its effect is the balance that realizes motor, reduces vibrations and noise; The motor equilibrium block all is to process with copper and Cuprum alloy in the compressor at present, and its important reasons is that copper or Cuprum alloy have diamagnetic performance; In the face of intense market competition, because the copper valency goes up, cause huge cost pressure for compressor factory, reducing cost is the task of top priority of each compressor producer.
Summary of the invention
A kind of non-magnetic alloy balance block for compressor use of providing at the deficiencies in the prior art is provided, it can satisfy fast technology of compressor balance and technological requirement, good processability is the alternative kind of desirable copper and Cu alloy material, greatly reduces cost of production.
The concrete technological scheme that realizes the object of the invention is:
A kind of non-magnetic alloy balance block for compressor use, it is to be that raw material forms through casting processing with iron, carbon, manganese, aluminium, vanadium, and the mass percentage content of its various materials is: manganese: 16.00～30.00%, carbon: 0.06～0.30%, aluminium: 0.50～2.50%, vanadium: 0.04～0.10%, all the other are iron and inevitable microimpurity.
The casting processing of described equilibrium block comprises following operation:
(1), casting: comprise and make mould, system shell, melting, casting, cleaning and finishing; Its casting temperature is 1450-1480 ℃.
(2), molten admittedly heat treatment: under 1020-1050 ℃, be incubated 15-24 hour, foundry goods is carried out molten admittedly heat treatment.
(3), surface sand-blasting: utilize high pressure draught to carry the sand material casting surface is impacted cleaning, remove oxide on surface.
(4), machining: foundry goods is carried out machining by its shape need.
Copper that uses in the alternative prior art of the present invention and Cuprum alloy equilibrium block reduce the consumption of copper product, reduce the compressor cost of production, remarkable in economical benefits.
