Abstract
The invention relates to cast iron alloy with high wear resistance and high-temperature stability. The cast iron alloy contains the following ingredients in percentage 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 alloy disclosed by the invention has remarkably-improved wear characteristics.
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 are used such machine, and this machine contains the machine part that noticeable wear occurs at the relatively high temperature that exceedes 500 ℃.For example, in cement process industry, so-called grog (clinker) water cooler is incorporated into the cement clinker of this clinker cooler for the cooling preceding kiln that is 1300～1450 ℃ from temperature.Described cement clinker is carried through this clinker cooler by suitable transmission of facility, and described transmission of facility consists of to-and-fro movement in the direction of motion of cement clinker and the element that therefore stands certain form of noticeable wear at the temperature of 500～900 ℃ conventionally.
Summary of the invention
The object of this invention is to provide the cast iron alloy at high temperature with 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.
