Abstract
The invention provides a kind of wearable cast steel.It is manganese 11.0～14.0% that this steel is formed, carbon 0.9～1.35%, silicon 0.05～0.8%, chromium 1.5～3.5%, owing to add an amount of chromium, improved the hardness and the wear resisting property of cast steel, it is applicable to the various equipment unit that the effect of impact contact load is arranged of processing, and improve 3～4 times than existing Mn13 cast steel work-ing life.
Description
The present invention relates to a kind of wear resistant alloy material, specifically a kind of wearable cast steel.
We know that high mangaenese steel has good wear resistance when the impact contact load is arranged, thereby is widely used on the mining machinery.March nineteen eighty-two, in " the mechanical fascicle " of " mechanical design handbook " that Chemical Industry Press publishes the 415th page, announced a kind of alloy composition of High Manganese Cast Steel, wherein contain manganese 11～14%, carbon 0.9～1.3%, P, the S of silicon 0.3～0.8% and trace, this cast steel does not contain chromium, the wear resistance of alloy is bad, influences its work-ing life; Patent 87108055.9 has been announced a kind of wear-resistant steel alloy, and wherein manganese 11.0～15.0%, carbon 1.6～3.0%, silicon 1.2～1.6%, chromium 9.0～10.8%, cerium 0.001～0.2%, vanadium 0.15～0.3%, titanium 0.05～0.3%, lead 0.05～0.15%, boron 0.005～0.015%, surplus is an iron, this cast steel alloying element is many, is difficult for processing, the cost height.
Purpose of the present invention is exactly in order to overcome the deficiency of existing High Manganese Cast Steel alloy, to provide a kind of prescription simple, handling ease, hardness height, the wear-resistant steel alloy material that wear resisting property is good.
For achieving the above object, a kind of wearable cast steel is characterized in that by manganese 11.0～14.0%, carbon 0.9～1.35%, and silicon 0.05～0.8%, chromium 1.5～3.5%, surplus is that iron is formed.The above-mentioned each component of the present invention is pressed the specified rate allotment, and through smelting, corresponding thermal treatment process casting such as quenching forms, and has wherein added 1.5～3.5% chromium.The adding refinement of an amount of chromium remaining carbide particle in the steel, and make it to be evenly distributed, increased the hardening capacity and the austenitic stability of steel, improve the hardness and the wear resistance of steel.Through evidence, less than 1.5%, then the hardness raising is not obvious as if the amount that adds chromium, and greater than 3.5%, then this cast steel workpiece fragility is big as if the chromium amount that adds, and is easy to be broken.The content of other component in the alloy is identical as carbon, silicon and prior art with effect, and this does not give unnecessary details.
The present invention fills a prescription simply, and it is easier greatly than polynary High Manganese Cast Steel to process, and it has good hardness and wear resisting property, washes away toughness and doubles than existing Hn13.The present invention can be used for processing the various equipment unit that the impact contact load is arranged.The jaw test of tup through being used for hammer mill and liner plate and jaw crusher, improve 3～4 times than existing Hn13 work-ing life.
Embodiment:
A kind of wearable cast steel, wherein contain manganese 13%, carbon 1.2%, silicon 0.6%, chromium 2.0%, surplus is an iron, this kind cast steel alloying element is few, handling ease, and hardness and impelling strength are enhanced about more than once than existing Hn13, the tup and the liner plate that are used for the casting hammer type crusher improve 4 times than existing Hn13 through test work-ing life.
