Definitions
- the invention relates to a method for producing abrasive grains from stainless steel casting, in which a melt is first hardenable iron-chromium-carbon alloy a granulate is produced which then undergoes a heat treatment at> 900 ° Celsius for hardening and then broken into sharp-edged grains.
- Two categories of blasting media made of stainless steel casting are known. These are, on the one hand, granules from spherical grains, which consist of steel materials of medium hardness ( ⁇ 45HR C ). As disclosed in JP 61 257 775, sharp-edged grains made of hardened chrome cast iron (> 60HR C ) are also used because they can achieve improved abrasive properties.
- the Production of the sharp-edged, hardened granules Compared to the abrasive grains of the first category, the Production of the sharp-edged, hardened granules a much higher Manufacturing effort with additional process steps required.
- the Production is according to JP 61 257 775 from a melt to a curable Chromium cast iron alloy starting from a granulate in essential round grains. This is hardened by following it a heat treatment is quenched in water at 1000 ° C to 1100 ° C. After that, the grains are broken, leaving a sharp-edged material arises.
- the present invention is based on the object To provide processes for the production of stainless abrasive, at oxidation during and after the final heat treatment of the granules can be excluded and in which the by Hardening reached brittleness of the material is so high that breaking the Blasting grain to sharp-edged granules is possible with simple means.
- this task solved in that the heat treatment in a reducing atmosphere follows and that only for the subsequent cooling reducing gas or gas mixture is used.
- the reducing atmosphere is expediently a Gas mixture containing hydrogen and nitrogen.
- Gas mixture is suitable, the 60% to 80% hydrogen and 20% to 40% nitrogen contains. The best results were achieved with 70% hydrogen and 30% Nitrogen.
- a vibrating tube mill is particularly suitable, order the desired sharp-edged from the hardened starting material To produce granules.
- the abrasive is classified according to the grain size.
- a further process step for grain fractionation with which the setting of the desired grain mixture is achieved, can be connected downstream of the production method according to the invention.
- the drawing shows a flow diagram of the manufacturing process, the the upper part comprises the process steps for producing the starting granulate, while the lower part shows hardening, breaking and classifying.
- the starting material for the abrasive is steel scrap, which is the manufacturing process is fed from a scrap warehouse 1.
- the desired Alloy is shaped into carbon from suitable storage containers of graphite 2 and chrome 3 added.
- the raw material mixture is then in one Melting furnace 4 melted into an alloy. This contains 2.0% carbon and 30% to 32% chromium.
- the melt passes through at a temperature of more than 1420 ° Celsius Spraying device 5, wherein a granulate with a wide range of Grain diameter arises.
- the atomized droplets of the molten metal become quenched in a water bath so that solid granules settle to the bottom a granulation basin 6 accumulates.
- Cooling 10 is the starting material for the rust-resistant Chrome cast alloy before.
- the starting granulate is now fed to a furnace 11, in which it is annealed at more than 900 ° C. in an atmosphere of hydrogen and nitrogen 13 at low pressure and then cooled, after which it is conveyed into a storage container 12.
- a furnace 11 By annealing the granulate at> 900 ° C, secondary carbides are separated from the alloy-rich matrix, which changes the composition of the matrix.
- a martensite conversion is only possible through the separation of the secondary carbides, which then leads to an increase in hardness to> 60 HR C when the granules cool down from temperatures> 900 ° C.
- the granulate is removed from the container 12 by means of a bucket elevator 14 Crushers 15 fed.
- the crusher 15 is preferably a vibrating tube mill trained and crushed the hardened, brittle granules to sharp edges Failure bodies. The use of such pulse mills makes it possible especially good, the material under strong internal tension disassemble sharp-edged fragments. The one created when breaking Grain mix has a wide size distribution.
- Now for classification pass through a screening plant 16.
- the crusher becomes too coarse oversize 17 fed again.
- the too fine undersize 18 becomes the process at this point removed and melted in the melting furnace 4.
- Gutkom 19 with one Diameters between 0.1 and 0.8 mm are either stored in a silo 20 or abandoned for fine classification of another screening plant 21. Blasting media with different grain sizes are used in silos 22, 23 and 24 stocked until removed for shipment to the end user become.
