Abstract
The present invention provides a non-magnetic metal alloy used for the balancing weight of a compressor, with a weight percentage of components as follows: Mn 5-20 percent, chromium 5-20 percent, sulfur 0.05-1.5 percent and the remainders are Fe and trace. The alloy can also contain Cu 0.4-3 percent and/or nickel less than or equal to 1.5 percent. The balancing weight used for a compressor can bemade by adopting the materials with a method of forging and pressing. Advantages of the method are that the working procedure is simplified, the pollution is lowered and the processing is flexible. Simultaneously, the adoption of forging and pressing rids the product of pores and slag inclusions, and improves the balancing capacity of the balancing weight.
Description
Technical field
The present invention relates to a kind of nonmagnetic steel ferroalloy materials, and use it to produce the method for compressor with counterbalance weight, and the counterbalance weight of producing with this method.
Background technology
Counterbalance weight is the vitals of compressor rotor, plays balance, noise reduction, damping effect.Compressor all is a copper alloy made with counterbalance weight at present, and owing to copper price height, starting material are in short supply, so production cost is higher at present.And the lead element that adds in the copper alloy is bigger to human body and environmental hazard, has been classified as one of six kinds of materials of forbidding by European Union.
Application number 200610116831 discloses a kind of metal alloy that is used for counterbalance weight in Chinese patent application, the carbon of the aluminium of its manganese, 0.50-2.50%, the vanadium of 0.04-0.10% and 0.06-0.30% by 16.00-30.00%, and the iron of surplus constitute.Yet the alloy material made from this prescription gets rusty easily because of no corrosion resistant element such as chromium, nickel, causes occurring in the compressor quality problems.In addition, by the alloy material that this prescription is made, workability is too desirable, can only make workpiece by casting.Casting need pass through molding, system shell, melting, casting, finishing, molten admittedly thermal treatment, surface sand-blasting and mechanical processing steps, production process is many, process-cycle is long, production efficiency is low, the shortcoming that cost is high, starting material will be poured in the mould by fusing, pollute greatly, also be difficult to be fit to cat and dog production needs in enormous quantities simultaneously.In addition, the product that goes out by casting processing is easy to generate defectives such as pore, slag inclusion, causes the counterbalance weight imbalance, influences the compressor use properties, so quality also is difficult to be improved.
Therefore the manufactured materials to counterbalance weight is improved, and not only helps worker spare to provide, but also can not cause the non-magnetic alloy material of waste of material to accord with the demands of the market.
Summary of the invention
The invention provides a kind of no magnetic metal alloy that is used for compressor with counterbalance weight, it comprises the manganese of weight ratio 5-20%, the chromium of 5-20%, the sulphur of 0.05-1.5% and the iron and the trace of surplus.It can also contain the copper of 0.4-3% and/or not be higher than 1.5% nickel.
Adopt above-mentioned materials to make the compressor counterbalance weight easily by the method for forging and pressing.This method has simplifies working process, and reduce to pollute, and processes advantage flexibly, simultaneously, owing to adopt forging and pressing, has eliminated the defectives such as pore, slag inclusion of product surface, has improved the balanced capacity of counterbalance weight.

Embodiment
The material that is used for the compressor balance piece should have nonmagnetic, corrosion resistant performance.For this reason, the alloy material that is used for the compressor balance piece provided by the invention mainly by manganese, chromium, sulphur, copper, and iron form.
Iron is as the basic ingredient of material of the present invention, because it is abundant and be easy to get at nature content, therefore, as cheap raw material, it always wishes that its consumption is The more the better under the prerequisite that the performance of material is protected, but for the consideration of performance, usually need to add some ancillary components, to improve its performance.
Manganese (Mn) and iron are the adjacent family elements with one-period, and character is very approaching, adds manganese in material, can play firm austenitic effect, makes material not have magnetic.Its erosion resistance far is better than iron simultaneously, is used for substituting the nickel in traditional stainless steel, can reach nonmagnetic, corrosion resistant effect.Also have other advantages with the manganese replacement nickel: the first, the fusing point of manganese (1244 ℃) is convenient to the melting of alloy far below the fusing point (1453 ℃) of nickel; The second, manganese is easy to get relatively, and its material cost is cheap relatively.In material according to the invention, the mass content of manganese suits between 5-20%.
In material of the present invention, comprise a certain amount of chromium, in order to the rust-proof effect of strongthener.Its suitable scope is between the 5-20%.
In order to regulate according to the present invention, can comprise an amount of sulphur and copper in the alloy material from the workability of alloy material.One of main purpose of the present invention is in order to produce workpiece by forging and pressing, therefore to require product to have certain plasticity.In material, add the machinability that sulphur can improve material.Through experiment, the contriver finds the scope of the 0.05-1.5% of sulphur content control is suited.In the present invention, the purpose that adds copper is to improve the machinability of material, and firm austenite improves forgeability and corrosion resistance nature, and its suitable consumption is between 0.4-3%, between the preferred 1.0-2.0%.If be lower than 0.4%, then do not reach it and improve effect, harmless if be higher than 3% to the performance of material itself, but cause cost to raise, make product not have the market competitiveness.
As preferably, in material of the present invention, can introduce an amount of nickel metal.As known, nichrome has good in oxidation resistance, intensity height, corrosion resistant characteristics, and therefore, the nickel of introducing may be brought into play synergy and improve above-mentioned character with chromium.The content of nickel generally is no more than 1.5% of material total mass.If be higher than 1.5%, harmless to the performance of material itself, but cause cost to raise, make product not have the market competitiveness.
Usually, because raw material in the final material of producing, usually contains a spot of carbon, silicon and phosphorus.Experiment shows, carbon is controlled at 0.15% below, silicon is controlled at below 1%, and phosphorus is controlled at below 0.05%, to the final material that is used for the object of the invention less than obstruction.
In material of the present invention, also may contain a spot of other impurity elements, it is to be introduced by raw material equally.
This material is made special-shaped bar by following technical process: melting-cast-blank moulding-hot rolling-cooling-straightening-thermal treatment-cold-drawn-straightening-check
