Abstract

A kind of alloy steel material for brake drum, including following raw material: Cr3C2- 25%NiCr composite granule, nanometer tungsten carbide cobalt composite powder, copper zirconium intermediate alloy, rare earth ferrosilicon alloy, molybdenum, manganese, niobium, surplus are iron and its inevitable impurity.Alloy steel material for brake drum of the invention, using iron as matrix, add high temperature resistant, the ceramic composite powder of wear-resisting erosion resistance, several functions intermediate alloy and high duty metal are compounded again, so that obtained brake drum has intensity high, thermal stability is good, wear-resisting erosion resistance and high-temperature behavior are good etc., and the rare earth composition and intermediate alloy of compounding, the good hybrid alloys of compactness can be formed, simultaneously these ingredients addition help to effectively reduce the intercrystalline in alloy away from, neutralize objectionable impurities, purify alloy and further refinement crystal grain, make to be evenly distributed inside alloy and tiny, to alloy material dense structure, intensity is good.

Description

A kind of alloy steel material for brake drum
Technical field
The invention belongs to brake drum technical fields, and in particular to a kind of alloy steel material for brake drum.
Background technique
Brake is in braking system to generate the component for hindering vehicle movement or movement tendency brake force.Automobile brake Device is nearly all to generate braking moment using the friction of fixing element and rotating element working surface in addition to various retarding devices Friction brake.Currently, the friction brake that is widely used of all kinds of automobiles according to the difference of rotating element can be divided into drum-type and Disc type two major classes.Its difference is: the rotating element in drum type brake friction pair is brake drum, using its internal surface of column as work Make surface；Rotating element in disk brake friction pair is discoid brake disc, using its both ends of the surface as working surface.Braking Drum is the fricting couple piece of drum brake, in addition to should have as strength and stiffness required for component, should also be had as high as possible And stable coefficient of friction and abrasion resistance, heat resistance appropriate, thermal diffusivity etc..
Summary of the invention
In view of the foregoing, it is an object to provide a kind of alloy steel material for brake drum, is prepared Brake drum is wear-resisting, heat-resisting and thermal diffusivity is good, be suitable for automobile more.
To achieve the goals above, the technical solution adopted by the present invention are as follows: a kind of alloy steel material for brake drum, by The raw material of following mass percent forms: Cr3C2- 25%NiCr composite granule 4.2-5.8%, nanometer tungsten carbide cobalt composite powder 0.8-1.3%, copper zirconium intermediate alloy 0.6-0.8%, rare earth ferrosilicon alloy 0.6-0.9%, molybdenum 0.8-1.1%, manganese 0.54- 0.7%, niobium 0.05-0.08%, surplus are iron and its inevitable impurity.
Wherein, Cr3C2Preparation method reference papers document " the spherical sintered state Cr of -25%NiCr composite granule3C2- 25% NiCr composite powder preparation research " (Second China National equipment remanufacturing engineering academic conference, 2016.10, Jinan).
The partial size of the nanometer tungsten carbide cobalt composite powder is 50-150nm.
The mass fraction of zirconium is 45% in the copper zirconium intermediate alloy.
Beneficial effects of the present invention: the alloy steel material for brake drum of the invention adds resistance to height using iron as matrix The ceramic composite powder of temperature, wear-resisting erosion resistance, then several functions intermediate alloy and high duty metal are compounded, so that obtained braking Drum has intensity is high, thermal stability is good, wear-resisting erosion resistance and high-temperature behavior are good etc., and the rare earth composition and intermediate alloy compounded, Can form the good hybrid alloys of compactness, at the same the addition of these ingredients help to effectively reduce the intercrystalline in alloy away from, Objectionable impurities is neutralized, purification alloy and further refinement crystal grain make to be evenly distributed inside alloy and tiny, thus alloy material group Densification is knitted, intensity is good.
