Abstract
The invention relates to a cast iron alloy with high tenacity. The cast iron alloy comprises the following components by weight percent: 2.1-2.3% of carbon, 2.8-3.0% of silicon, 0.1-0.3% of magnesium, 0.02-0.04% of chromium, 0.003-0.005% of boron, 0.1-0.12% of copper, 0.1-0.3% of tungsten, 0.01-0.03% of titanium, 0.001-0.003% of lanthanide rare earth and the balance of iron. The ductile cast iron alloy is suitable for shaft parts and chassis parts of lorries and saloon cars, such as tie rods, wheel carriers and slewing bearings and endures high mechanical and dynamic stresses.
Description
Technical field
The invention belongs to metal material field, refer to there is high mechanical strength, high-wearing feature and the cast iron alloy simultaneously with high tenacity.
Background technology
In automobile making, apply cast iron alloy and prepare the foundry goods must with high tenacity, retarding disc for example, it needs automobile kinetic energy to be transformed into heat energy in braking procedure.At this moment this retarding disc can reach approximately 850 ℃.In braking procedure, not only coating is braked in wearing and tearing, and retarding disc also weares and teares.Retarding disc has irregular wearing and tearing, and is conventionally still under warranty and needs manufacturer to replace with expensive.For making to occur as far as possible equably in the lip-deep wearing and tearing of retarding disc, this structure has been proposed to high crystalline structure and uniformity requirement.By suitable castmethod, can improve homogeneity.
Summary of the invention
The object of this invention is to provide a kind of cast iron alloy that there is high mechanical strength, high-wearing feature and there is high tenacity simultaneously.
The present invention is achieved by the following technical solutions:
A kind of have a ductile castiron alloy, its composition is that the carbon of 2.1-2.3%, the silicon of 2.8-3.0%, the magnesium of 0.1-0.3%, the boron of the chromium of 0.02-0.04%, 0.003-0.005%, the tungsten of the copper of 0.1-0.12%, 0.1-0.3%, the lanthanide rare of the titanium of 0.01-0.03%, 0.001-0.003% and surplus are iron by weight percentage.
Further, described nodular cast iron alloy, its composition also includes the manganese of 0.1-0.12% by weight percentage.
The invention has the beneficial effects as follows:
Nodular cast iron alloy of the present invention is suitable for the spindle unit of cargo truck and car and vehicle chassis component as drag link, wheel carrier and turntable bearing, and it stands high machinery and dynamic stress.
Embodiment
A kind of have a ductile castiron alloy, its composition is that the carbon of 2.1-2.3%, the silicon of 2.8-3.0%, the magnesium of 0.1-0.3%, the boron of the chromium of 0.02-0.04%, 0.003-0.005%, the tungsten of the copper of 0.1-0.12%, 0.1-0.3%, the lanthanide rare of the titanium of 0.01-0.03%, 0.001-0.003% and surplus are iron by weight percentage.
Cast iron alloy of the present invention, its Brinell hardness is greater than 220, and when applying as retarding disc, is wearing and tearing as far as possible uniformly.Graphite in this cast iron alloy can be spherical or vermiform, but non-stratiform or sheet.Although the retarding disc price containing lamellar graphite is low, its resistance to temperature alternating is poor.Therefore after the short period of time is used, can produce the so-called thermal crack that is subject to, this rapid crack also causes surface irregularity.Uneven surface causes inhomogeneous temperature load, inhomogeneous wearing and tearing again and causes so-called squeal sound.

Embodiment 2
A kind of have a ductile castiron alloy, its composition is that 2.1% carbon, 2.8% silicon, 0.1% magnesium, 0.1% tungsten, 0.01% titanium, 0.02% chromium, 0.001% boron, 0.1% copper, 0.001% lanthanide rare, 0.1% manganese and surplus are iron by weight percentage.
Embodiment 3
A kind of have a ductile castiron alloy, its composition is that 2.2% carbon, 2.85% silicon, 0.15% magnesium, 0.03% chromium, 0.2% tungsten, 0.015% titanium, 0.0015% boron, 0.11% copper, 0.0015% lanthanide rare, 0.11% manganese and surplus are iron by weight percentage.
Claims (2)
