Description

A kind of power station desulfurization ball mill alloy lining
Technical field:
The present invention relates to ball mill technical field, specifically a kind of power station desulfurization ball mill alloy lining.
Background technology:
Power station desulphurization system ground the ball mill of Wingdale processed, in the use procedure of original design rubber liner, system maintenance difficulty occurs, grind defects such as making that power is little, rubber liner work-ing life is low. After rubber liner is improved to metal backing, although can the operation factor of lift technique to a certain extent and efficiency, but still to have work-ing life low for common metal sheet, the problem of wear resistance difference. High-vanadium high-speed steel not only has very high hardness and suitable toughness, and has excellent wear resistance, and therefore as wear-resisting material of new generation, high-vanadium high-speed steel receives much concern. Research shows, the wear resistance of high-vanadium high-speed steel is more than 3 times of rich chromium cast iron, is more than 10 times of high mangaenese steel, has been used to the multiple wearing pieces such as roll, tup, ball grinding machine lining board and rotor body. Therefore both alloy phases are combined form the alloy with two kinds of common advantages of alloy and be applied to the production of tup very necessary.
Summary of the invention:
Technical problem to be solved by this invention is to provide a kind of wear resisting property good, it may also be useful to the life-span is long, the operation factor of lift technique and the power station desulfurization ball mill alloy lining of efficiency.
The technical problem solved is adopted following technical scheme:
A kind of power station desulfurization ball mill alloy lining, it is characterized in that: described alloy is by following, materials in percentage by mass forms, carbon C:1.8��3.0%, silicon Si:0.3��1.2%, manganese Mn:0.3��3.0%, chromium Cr:2.0��4.0%, molybdenum Mo:0.1��3.0%, vanadium V:0.2��0.5%, titanium Ti:0.05��1.0%, bismuth Bi:0.002��0.008%, antimony Sb:0.01��0.08%, rhenium Re:0.01��0.02%, all the other are iron, the mass percent of element A is defined as X (A), above-mentioned raw materials then exists following relation, X (C)+4X (Si)=10X (V)+100X (Bi)+100X (Re).
Described alloy carries out hot composite molding by high-vanadium high-speed steel and low-carbon alloy steel rich chromium cast iron when pouring into a mould.
Described low-carbon alloy steel high chromium cast iron material is made up of following materials in percentage by mass, carbon C:2.6��3.0%, silicon Si:0.3��1.2%, manganese Mn:0.3��3.0%, chromium Cr:2.0��3.0%, and all the other are iron; Or being made up of following materials in percentage by mass, carbon C:0.1��0.6%, silicon Si:0.3��1.2%, manganese Mn:0.3��3.0%, chromium Cr:0.0��2.0%, all the other are iron.
The present invention utilizes high-vanadium high-speed steel antiwear characteristic, organizes crystallization property and physicals thereof, carries out hot composite molding with low-carbon alloy steel when pouring into a mould. Product life improves 2��6 times on the basis of rich chromium cast iron tup.
The add-on of the raw material of the considered critical in the present invention and proportionlity so that form good stability fine granular structure in alloy, considerably increase its wear resistance.
The invention has the beneficial effects as follows: material of the present invention can improve 2��6 times relative to wear resistance of high-chromium iron, greatly improving its work-ing life, metallographic structure is fine granular structure, is conducive to operation factor and the efficiency of lift technique.
Embodiment:
