Description
Technical field
The present invention relates to a kind of ultra-high manganese steel that adopts and make sieve plate and manufacture method thereof that stone classification is used, belong to sieve plate and make the field.
Background technology
All Granted publications of the applicant number are CN1214372C, title " sieve plate for sorting stone material and manufacture method thereof ", and this comprises the high mangaenese steel substrate of some sieve apertures to sieve plate.During the sieve plate casting, earlier in the nowel molding sand, mould out the die cavity that meets the sieve plate specification with mould, the core hole that meets each sieve aperture position, insert the cylindrical compound grease sand loam core of unified size in each core hole, the height that the loam core exceeds nowel molding sand face is slightly larger than plate thickness, cover top part and inject 1350～1600 ℃ high mangaenese steel molten steel, insert process furnace after the cooling deburring, be warming up to 650 ℃ of insulations 1～2 hour with the amplitude that per hour heats 50 ℃, 950～1100 ℃ of insulations 1～2 hour again heat up, foundry goods gets sieve plate of the present invention with blowing atomized water spray cooling by force after pressing is proofreaied and correct after coming out of the stove.Though changing the number of times of sieve plate, the said products significantly reduces, reduce maintenance load, guaranteed the screening quality of building stones, reduced cost, the sieve plate that changes can also melt down again as raw material produces new sieve plate, reduce pollution, obtained good economic benefits and environmental benefit, still, in the application of reality, since the material difference of building stones, the hardness difference, and the screening effect that is produced is different fully.Particularly for the higher relatively mechanically resistant material of building stones material hardness level, the quantity not sufficient that contains owing to manganese in the high mangaenese steel sieve plate, formed high mangaenese steel sieve plate is under high-frequency vibration, impact and the wearing and tearing of building stones that are not enough to contend with of its surface hardness to it, cause high mangaenese steel sieve plate not only quick abrasion, life-span weak point, and easily damaged, caused the high mangaenese steel sieve plate frequently to change by the building stones of high-frequency vibration, directly have influence on the screening efficiency of building stones, and cause increasing substantially of the product cost of screening.
Summary of the invention
Purpose of design: the weak point of avoiding background technology to exist, provide that a kind of can either to be suitable for stone matter hardness harder, improve screening efficiency, can prolong the sieve plate ultra-high manganese steel sieve plate for sorting stone material and the manufacture method thereof in work-ing life again.
Design: in order to realize above-mentioned purpose of design.Selecting the component of ultra-high manganese steel material and the content of weight percent scientifically and rationally, is major technique feature of the present invention.The purpose of doing like this is: the one, because ultra-high manganese steel does not occur in present market as yet, more be not specifically designed to the ultra-high manganese steel sieve plate that the stone flour classification is used, therefore the component of ultra-high manganese steel constitute and the design of weight percent content whether scientific and reasonable, can the ultra-high manganese steel that directly has influence on the application and developed be used for the sizing screening of required stone material; The 2nd, because the high mangaenese steel manganese content is low, the as-cast structure of steel is austenite and carbonization tissue, after heating Water Quenching (being commonly referred to the tough processing of water) about through 1000 ℃, the carbide of a part is solid-solubilized in the austenite, a part can't be solid-solubilized in the austenite, though have good plasticity and toughness, under the effect of bigger impact load or contact stress, upper layer can produce work hardening, and there is martensite and the ε crystal-plane slip that hands down to form, surface hardness sharply raises, inner then still keep good toughness, but its surface hardness still can't be born impact and the wearing and tearing that the hard stone material is brought under high-frequency vibration, the breakage rate of its sieve plate and wear rate are high, directly cause waste of material, environmental pollution and inefficiency.In order to solve under greater impact load or contact stress high mangaenese steel surface hardness deficiency, problem that abrasion loss is big, the application is when improving high mangaenese steel content, amount according to getting manganese, develop the ultra-high manganese steel stone classification sieve plate that is specifically designed to the hard stone screening by testing rationally definite carbon and silicon addition, the building stones that both can bear under the high-frequency vibration impact, have good wear resistance again, prolonged the work-ing life of sieve plate simultaneously, improved screening efficiency.Through test, the application's product sieve plate is in the screening that is used for gradient hardness's building stones, the building stones higher for screening hardness, and the efficient of its screening has reached 98%, and sieve plate reaches 6～8 months work-ing life, has obtained beyond thought economic benefit and technique effect.
Technical scheme 1: ultra-high manganese steel sieve plate for sorting stone material, it comprises the substrate 2 of some sieve apertures 1, and the material of described substrate 2 is a ultra-high manganese steel, and the component of ultra-high manganese steel material and weight percent content scope are:
Iron 73.8～84.5%,
Manganese 14.01～25%,
