Abstract
The present invention relates to a wear and corrosion resistant non-magnetic steel which is suitable for a ball mill lining plate and other occasions requiring wear resistance, corrosion resistance and no magnetic conduction. The steel uses P as a key element added into the steel, and a certain amount of Mn, Cr, Al and the like are simultaneously added to the steel. The steel can be smelted in a converter, an electric furnace and an open-hearth by using a cast moulding process. The steel can realize single austenite metallographic structures after thermal treatment, and the magnetic conductivity mu is only about 1.0020 Gs/Oe. The steel can prolong the service life of an inner liner of a ball mill to 5 to 7 years when the steel is used on the inner liner of a ball mill, and the service life of the inner liner is 5 to 7 times of that of the commonly used heavy rail steel lining plate.
Description
The present invention relates to a kind of wear and corrosion-resistant non-magnetic steel, belong to the metallic substance technical field.Be applicable to that ball mill and other require wear resistant corrosion resistant and non-magnetic occasion.
Before the present invention makes, impact, wearing and tearing, corrosion and not the magnetic conduction occasion still do not have ripe steel grade with steel.Steel for ball mill lining Working environment and performance requriements are very harsh, use the heavy rail steel bar to substitute because of can not find suitable material over a long time, extremely lack work-ing life (generally at 7～16 months).Japanese Patent clear 58-197256 proposes a kind of atmospheric corrosion resistance and the good high Mn steel of high tenacity of resistance to rust, and its one-tenth is grouped into and is, C:0.10～1.00%; Mn:16～35%; Si:0.20～3.00%; Cr:0.50～18.00%; Al:0.01～7.00%; Cu:0.01～2.00%; N :≤0.3%.This steel carries out strictness control to P as impurity, so its obdurability solidity to corrosion can not show fully that still range of application also is restricted.
Purpose of the present invention proposes the anti-corrosion nonmagnetic steel of a kind of corrosion resistant exactly, to solve in impact, wearing and tearing, corrosion and to need the not steel problem of magnetic conduction occasion.
Wear and corrosion-resistant non-magnetic steel of the present invention, its composition weight percent composition is C:0.35～1.50%; Mn:13～35%; Cr:5～11%; Al:0.5～9%; P:0.1～1.5%; Si:0.1～2%, all the other are Fe and unavoidable impurities.C wherein is the effective element that improves steel intensity and wear resistance, and can enlarge γ-phase region and improve hardening capacity.Mn is the effective element of formation and stable austenite, and it also can improve the obdurability of steel simultaneously.Cr can make steel produce passivation phenomenon, obviously improves the resistance of oxidation of steel, strengthens corrosion stability, also is the effective element that improves physical strength and wear resistance.Al can reduce the coercive force of steel, and a certain amount of Al also can make steel produce passivation phenomenon, improves the corrosion stability of steel in oxidizing acid, to increase the anti-corrosion capability of steel.P is the key element in the steel grade of the present invention, and it can not only improve the corrosion stability of steel effectively, and can strengthen molten steel flow, is suitable for molten steel agglomeration moulding.Si can improve the acid corrosion-resistant performance of steel and improve the competency of steel.
Wear and corrosion-resistant non-magnetic steel of the present invention can be smelted in converter, electric furnace and open hearth, and adopts the casting moulding, teeming temperature t 〉=1580 ℃, need after the moulding to heat-treat in 1050～1150 ℃ of temperature, the steel perlite after the processing disappears, and becomes not magnetic conduction tissue of single austenite.
Erosion resistant nonmagnetic steel embodiment composition weight percent composition of the present invention is C:0.62%; Mn:18.79%; Cr:4.67%; Al:0.89%; P:0.69%; Si:0.24%, casting and after heat treatment, its metallographic of microscopic examination becomes single austenite structure, magnetic permeability mu=1.0020Gs/Oe.This casting sheet material is used on China's certain mine ball mill liner of the north, in weak acidic medium, overwhelm and collide and friction, check that after the use in 2.5 years the amount of deteriorating is extremely slight, estimation can be used more than 5～7 years, was 5～7 times of heavy rail bar steel (former ball mill liner with heavy rail bar steel) work-ing life.
