Abstract
The invention discloses a manufacture technology for compositing a high-chromium alloy ceramic grain composite on the surface of a wear-proof machine part, which comprises the following steps of: preparing a high-chromium alloy ceramic grain composite grid; fixing the high-chromium alloy ceramic grain composite grid on the shaped surface; and casting the machine part, so that the high-chromium alloy ceramic grain composite grid is fixed on the surface of the machine part. The manufacture technology organically combines the wear-proof resistance of the ceramic grain material with the mechanical performance of the high chromium alloy, can manufacture the composite material with good rigidity, impact resistance and wear resistance, can manufacture the composite material with the shape of grid, can manufacture the composite with various shapes and sizes such as taper, arc, arc and the like, secondly casts the super-hard netty composite to form into the wear-proof product as required, and can effectively meet the requirement of the work condition of crushing resistance and wearing resistance of the equipment.
Description
Technical field:
The present invention relates to a kind of production technology of compositing high-chromium alloy ceramic grain composite on surface of wear-proof machine part.
Background technology:
Present surface at a lot of wear-resistant equipment components, adopt the mechanical bond pattern, inlay the high-chromium alloy liner plate, have then directly at surface of the work built-up welding high-chromium alloy, reaching the friction durability of elongated component, but because production status is very abominable, the existing anti-fracture reliability of requirement equipment, must have wear-resistant wearability again, service life is generally at 8000～12000 hours, and abrasion-proof backing block grinding roller, the mill of experience wear must be repaired or change.
Summary of the invention:
The object of the present invention is to provide a kind of production technology that can effectively reach the compositing high-chromium alloy ceramic grain composite on surface of wear-proof machine part of the anti-fragmentation of equipment, the working condition requirement that resistance to wears.
Technical solution of the present invention is:
A kind of production technology of compositing high-chromium alloy ceramic grain composite on surface of wear-proof machine part is characterized in that: comprise the following steps: successively
(1) preparation high-chromium alloy ceramic particle composite grids:
The high-chromium alloy fusing is placed in the steel ladle, the particle diameter that adds through sintering crushing in steel ladle is 80～100 purpose aluminium oxide and/or zirconia particles, after mixing mixed liquor is injected the grid sand mold, cool off then and take out, obtain high-chromium alloy ceramic particle composite grids;
(2) high-chromium alloy ceramic particle composite grids is fixed on the moulding surface, parts are cast, make high-chromium alloy ceramic particle composite grids be fixed on surface of the work.
The addition of described aluminium oxide and/or zirconia particles by volume percentage counts 30%～40%.
Described aluminium oxide, zirconia particles are that content is 95% or 99% particle.
The specification of grid sand mold is that to make the composite gridding thickness that makes be 15～20mm.
Described wear-resisting parts are abrasion-proof backing block, coal pulverizer grinding roller cover or mill.
The present invention organically combines the anti-wear performance of ceramic particle material and the mechanical performance of high-chromium alloy, composite hardness, the shock resistance, wear-resistant of producing, be shaped as latticed, can be made into various appearance and sizes such as taper, arc, circle etc., this superhard netted compound is cast by secondary, form required wear resistant products, the equipment that can effectively reach is anti-broken, working condition requirement resistance to wears.
The material hardness that the present invention produces can reach 3～4 times of high-chromium material, can improve or prolong more than the service life several times of equipment attrition parts, it is long that thereby the equipment use reaches the cycle, produce stable, reliable, can be widely used in industries such as electric power, cement, iron and steel, building materials, be all kinds of wear-resisting parts such as all kinds of abrasion-proof backing blocks, vertical mill roller shell, mill, grinder hammerhead, ball mill charging aperture.
