Description
Technical field
The present invention relates to a kind of Medium Manganese Steel component and weight percent content and constitute, and make sieve plate and the manufacture method thereof that stone classification is used, belong to sieve plate and make the field with Medium Manganese Steel.
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 relatively low soft material of building stones material hardness level, because the high mangaenese steel sieve plate is under high-frequency vibration, its hardness is very high, the collision that building stones and high mangaenese steel sieve plate produce, be not only effect, but also played the side effect of secondary vibration fragmentation, the screening yield rate of building stones is reduced greatly the building stones screening, the secondary breakage rate of building stones then improves greatly, has directly caused the increasing substantially of waste, environmental pollution and the product cost of screening of material.
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 lower, improve screening yield rate and efficient, can reduce the Medium Manganese Steel sieve plate for sorting stone material and the manufacture method thereof of sieve plate manufacturing cost again.
Design: in order to realize above-mentioned purpose of design.Selecting the component of Medium 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 Medium Manganese Steel does not occur in present market as yet, more be not specifically designed to the Medium Manganese Steel sieve plate that the stone flour classification is used, therefore the component of Medium Manganese Steel constitute and the design of weight percent content whether scientific and reasonable, can the Medium Manganese Steel that directly has influence on the application and developed be used for the sizing screening of required stone material; The 2nd, because high mangaenese steel manganese content height, 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 the overwhelming majority is solid-solubilized in the austenite, steel be organized as single-phase austenite or austenite adds minor amount of carbide, therefore has good plasticity and toughness, and crack growth rate is very low, particularly under the effect of bigger impact load or contact stress, upper layer produces work hardening rapidly, and there is martensite and the ε crystal-plane slip that hands down to form, its surface hardness sharply raises, inner then still keep good toughness, therefore have good wear resistance, and can withstand shocks load and unlikely breaking.In order to solve the too high problem of sclerosis that high mangaenese steel is produced under greater impact load or contact stress, the application is when reducing Medium Manganese Steel content, amount according to getting manganese, rationally determine carbon and silicon addition by testing, the fragmentation that both can avoid the high mangaenese steel sieve plate surface hardness soft building stones secondary vibration that causes really up to the mark to be caused, guaranteed the yield rate of building stones screenings again, improved screening efficiency, because the Medium Manganese Steel sieve plate has good wear resistance and toughness, improved significantly its work-ing life again simultaneously.Through test, the application is in the screening that is used for gradient hardness's building stones, and the secondary destructive rate of screening building stones has been reduced more than 95%, and the qualification rate of screening has reached 98%, sieve plate reaches more than 6 months work-ing life, has obtained beyond thought economic benefit and technique effect.
Technical scheme 1: the Medium 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 Medium Manganese Steel, and the component of Medium Manganese Steel material and weight percent content scope are:
