Abstract
The invention discloses a heat-resistant wear-resisting rare earth sieve plate which is provided with a sieve mesh, wherein the sieve mesh and the heat-resistant wear-resisting rare earth sieve plate are shaped once by sand mold casting. The heat-resistant wear-resisting rare earth sieve plate disclosed by the invention is characterized in that the sieve mesh on the sieve plate and the heat-resistant wear-resisting rare earth sieve plate are shaped once by sand mold casting, the process of drilling or punching processing is omitted after the sieve plate is cast and shaped, and the mechanical property of the shaped sieve plate is not damaged; meanwhile, the sieve plate comprises the following chemical components of Cr, Mo, Ni, Mn and Nb elements and has better heat and wear resistance; and the service life of the sieve plate is greatly prolonged.
Description
Technical field
The present invention relates to a kind of sieve plate, belong to the forming materials technical field.
Background technology
Sieve plate is the vitals that uses in the screening process, the structure of sieve plate, material to sieving capacity, efficient, race is rough and careless and the life-span produces material impact.Therefore, sieve plate must have enough intensity, higher percent opening and be difficult for performances such as plug-hole.That the principal element that influences at present the sieve plate life-span is is heat-resisting, anti-wear performance is not high.And the sieve aperture on the present sieve plate is normally holed behind the sieve plate casting again or punching processing forms, and this sieve aperture molding mode has changed the mechanical property of sieve plate, thereby has influenced the service life of sieve plate.
Summary of the invention
Technical problem to be solved by this invention provides a kind of rare earth heat-resistant antifriction sieve plate, has the better heat-resisting wearability, has improved the service life of sieve plate greatly.
For solving the problems of the technologies described above, the invention provides a kind of rare earth heat-resistant antifriction sieve plate, have sieve aperture, it is characterized in that described sieve aperture and rare earth heat-resistant antifriction sieve plate adopt the sand casting one-shot forming.
Comprise Cr, Mo, Ni, Mn, Nb, V element in molten steel during casting.
Described constituent content is respectively: Mn:3%, Cr:20%, Ni:4%, Mo:0.3%, Nb:0.1%.，V：0.3%。
The beneficial effect that the present invention reached:
Rare earth heat-resistant antifriction sieve plate of the present invention, sieve aperture on it and rare earth heat-resistant antifriction sieve plate adopt the sand casting one-shot forming, need behind the sieve plate casting, not hole again or punching processing, reduce the operation of punching, and not destroy the mechanical property of molded sieve plate; Simultaneously in the chemical composition of sieve plate, comprise Cr, Mo, Ni, Mn, Nb element, had better heat-resistant antifriction, improved the service life of sieve plate greatly.
The specific embodiment
Below the present invention is further described.Following examples only are used for technical scheme of the present invention more clearly is described, and can not limit protection scope of the present invention with this.
Rare earth heat-resistant antifriction sieve plate of the present invention, have sieve aperture, sieve aperture and rare earth heat-resistant antifriction sieve plate adopt the sand casting one-shot forming, need not hole or punching processing behind the sieve plate casting again, reduce the operation of punching, and do not destroyed the mechanical property of molded sieve plate.
Comprise Cr, Mo, Ni, Mn, Nb, V element in molten steel during casting.Constituent content is respectively: Mn:3%, Cr:20%, Ni:4%, Mo:0.3%, Nb:0.1%, V:0.3%.Make sieve plate have better heat-resisting, anti-wear performance.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the technology of the present invention principle; can also make some improvement and distortion, these improvement and distortion also should be considered as protection scope of the present invention.
Claims (3)
