Abstract
The invention discloses a high chromium wear-resistant iron casting for compressors. The high chromium wear-resistant iron casting for compressors consists of the following components by mass: 3.5%-3.8% of C, 13.5%-16.0% of Cr, 0.5%-0.8% of Si, 0.1%-0.3% of Mn, 1.5%-2.0% of Ni, less than or equal to 0.02% of Mg, 0.02%-0.04% of Sb, 0.5%-0.6% of Cu, less than or equal to 0.025% of P, 0.02%-0.05% of S, and the balance Fe and unavoidable impurities. By the means, the high chromium wear-resistant iron casting for compressors involved in the invention can improve its wear resistance, oxidation resistance and toughness under the premise of reducing iron casting hardness, so that during cutting machining, wearing of cutting tools can be reduced greatly, and cutter sharpening frequency is reduced, thereby improving the cutting machining efficiency.
Description
Technical field
The present invention relates to ironcasting field, particularly relate to a kind of compressor Abrasion Resistant High Chromium Cast Iron part.
Background technology
Ironcasting, is mainly used in automobile, lathe, air compressor and hydraulic part etc.In recent years, compressor of air conditioner cylinder iron part all adopts high-quality spheroidal graphite casting, and its over-all properties, close to steel, has excellent intensity, toughness and wear resistance.But because its sulphur content is higher, be generally 2.2%-2.8%, the sulfide of generation not only consumes nodulizing agent, cause nodularization unstable, but also inclusion is increased, cause the casting flaw such as slag inclusion, pore.
High-chromium cast iron piece, because it has higher chromium content, good hardness, wear resistance and oxidation-resistance, is usually used in the operating mode of various abrasive wear, high temperature wear and corrosive wear.But the chromium too high levels in existing high-chromium cast iron piece, is generally 23.0%-28.0%, the actual hardness of foundry goods is usually up to more than HRC50, causes that spray hardness is high, cutting tool loss is fast, working (machining) efficiency is low and aperture such as cannot to process at the problem.
Summary of the invention
The technical problem that the present invention mainly solves is: for the deficiencies in the prior art, a kind of compressor Abrasion Resistant High Chromium Cast Iron part is provided, its wear resistance, oxidation-resistance and toughness can be improved under the prerequisite reducing ironcasting hardness, it is made greatly to reduce the wearing and tearing of cutter when machining, reduce the sharpening frequency, thus improve machining efficiency.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of compressor Abrasion Resistant High Chromium Cast Iron part, described compressor Abrasion Resistant High Chromium Cast Iron part comprises the following ingredients formed by mass percentage: C:3.5%-3.8%, Cr:13.5%-16.0%, Si:0.5%-0.8%, Mn:0.1%-0.3%, Ni:1.5%-2.0%, Mg :≤0.02%, Sb:0.02%-0.04%, Cu:0.5%-0.6%, P :≤0.025%, S:0.02%-0.05%, all the other are Fe and inevitable impurity.
