Abstract
The present invention relates to a cast iron alloy with characteristics of high wear resistance and high temperature stability, wherein the components comprise, by weight, 11-13% of chromium, 2.1-2.3% of carbon, 1.5-2.0% of manganese, 1.5-1.8% of silicon, 5.0-7.5% of nickel, 0.001-0.003% of boron, 0.03-0.05% of tungsten, 0.3-0.5% of molybdenum, 0.3-0.5% of vanadium, and the balance of iron and unavoidable impurities. The cast iron alloy of the present invention has the significantly-improved wear characteristic.
Description
Technical field
The invention belongs to ferroalloy materials, specifically refer to a kind of cast iron alloy of high-temperature stable of high-wearing feature.
Background technology
Many industries use such machine, and this machine contains the machine part that noticeable wear occurs at the relatively high temperature more than 500 DEG C.Such as, in cement manufacturing industry, so-called grog (clinker) water cooler is incorporated into the cement clinker this clinker cooler for the preceding kiln that to cool from temperature be 1300 ~ 1450 DEG C.Described cement clinker is carried through this clinker cooler by suitable transmission of facility, described transmission of facility usually by to-and-fro movement in the direction of motion of cement clinker and the element therefore standing certain form of noticeable wear at the temperature of 500 ~ 900 DEG C form.
Summary of the invention
There is under the object of this invention is to provide high temperature the cast iron alloy of higher wear resistance.
The present invention is achieved by the following technical solutions:
A kind of cast iron alloy of high-temperature stable of high-wearing feature, its composition includes by weight percentage, the nickel of the manganese of the chromium of 11-13%, the carbon of 2.1-2.3%, 1.5-2.0%, the silicon of 1.5-1.8%, 5.0-7.5%, the boron of 0.001-0.003%, the tungsten of 0.03-0.05%, the molybdenum of 0.3-0.5%, the vanadium of 0.3-0.5%, surplus is iron and inevitable impurity.
In described inevitable impurity, the total amount of nitrogen, p and s should not be greater than 0.1% of cast iron alloy by weight percentage.
The invention has the beneficial effects as follows;
The wearing character that alloy tool according to the present invention is significantly improved.
