Problems solved by technology

However, the alloy material made with this formula is easy to rust due to the absence of corrosion-resistant elements such as chromium and nickel, resulting in quality problems in the compressor
In addition, the alloy material made of this formula has unsatisfactory machinability, and the workpiece can only be manufactured by casting, and the surface flatness and magnetic permeability of the manufactured balance weight product are relatively poor; and, the above-mentioned patent It also does not involve in order to produce a balance weight with better performance and lower cost, how to further reduce the magnetic permeability of the product alloy by improving the alloy composition or ratio, and improve the flatness, machinability and workability of the alloy balance weight product. productive technical content

Embodiment 1

[0032] In Example 1, on the basis of a certain amount of casting pig iron and steel scrap, weigh the electrolytic Mn 15%, Mo 0.3%, Cr 0.5%, Ni 0.3%, V 0.1% and Ti 0.2% by weight of the final total alloy material. % Carry out the smelting and post-treatment procedures according to the above method, and finally obtain the ferroalloy material. After testing, the main components of the ferrous alloy material are:

[0033] Mn: 16.5%, Mo: 0.3%, Cr: 0.6%, Ni: 0.4%, V: 0.1%, Ti: 0.2%, C: 2.0%, Si: 1%, S: 0.05%, P: 0.03; The amount is mainly iron and other unavoidable impurities.

[0034] The metallographic test was carried out on the balance block ferrous alloy product prepared above, and the test results were as follows: figure 1 As shown, it can be seen from the metallographic photographs that in the metallographic micrographs magnified by 50 times and 200 times, the entire metallographic structure is 100% austenite structure; after magnetic performance testing, its magnetic inducti...

Embodiment 2-5

[0036] The same method as in Example 1 was adopted, except that the ratio of each element in the final iron alloy material was adjusted. See Table 1 for the main components and various properties of the ferrous alloy material products prepared in Examples 2-5.

Abstract

The invention provides an iron alloy material, in particular to a multi-element iron alloy material for manufacturing a balance block of an air-conditioning compressor. The iron alloy material comprises a main component iron and further comprises the following components of manganese (Mn), molybdenum (Mo), chromium (Cr), vanadium (V), nickel (Ni) and titanium (Ti). When the iron multi-element alloy material is used for precisely casting flat thin products, the flatness is excellent, machining or a cold and heat treatment process is used for few times or not used, the product with the flatnessof less than or equal to 0.2 can be directly obtained according to the normal process treatment, the cost advantage is large, no magnetic rate exists, and the qualified ratio of the product is high.

Description

technical field [0001] The invention relates to an iron alloy material, in particular to an iron multi-element alloy material used in the balance weight of an air-conditioning compressor, and a compressor balance weight produced with the material. Background technique [0002] Because the motor of the air-conditioning compressor drives the eccentric crankshaft to rotate at high speed, it is generally necessary to install a balance weight on its rotor to obtain dynamic balance. For the balance weight, in addition to requiring higher density, more accurate dimensional accuracy and higher weight accuracy Generally, it is also required to be non-magnetic and non-magnetized. The magnetic balance weight will affect the magnetic circuit distribution when the motor is working, and then affect the operating efficiency of the motor; the existing balance weights are generally made of brass, stainless steel or high manganese steel. However, in recent years, the price of copper has risen...
