Definitions
- the invention relates to a method for producing abrasive grains from rustproof stainless steel casting, in which a granulate is first produced from the melt of a hardenable iron-chromium-carbon alloy, which then undergoes a heat treatment for hardening and is subsequently broken down into sharp-edged grains.
- rusting blasting media such as steel shot or steel gravel
- rusting blasting media such as steel shot or steel gravel
- iron-containing residues on the workpiece surface. Due to the oxidation of the adhering iron residues, rust spots appear undesirably within a very short time.
- mineral abrasives such as. B. electrical corundum, silicon carbide or glass
- rust-free metallic abrasives are known. Mention should be made of cast stainless steel shot from rust-resistant steel alloys. This material has a number of advantages over mineral abrasives.
- a granulate consisting of essentially round grains is first produced from a melt of a hardenable chromium cast iron alloy. This is hardened by being quenched in water after a heat treatment at 1000 ° C to 1100 ° C. Then the grains are broken so that a sharp-edged material is formed.
- a disadvantage of this method is that the undesired oxidation of the material is promoted by quenching the steel, which is hotter than 1000 ° C., in water. Furthermore, the achievable cooling rate is severely limited when using water (vapor phase). However, effective quenching is absolutely necessary in order to obtain a material that is as brittle as possible. This is the prerequisite that the grains can later be broken so that the desired sharp-edged granules are produced.
- the object of the present invention is to provide a process for the production of rustproof abrasive in which oxidation of the granules is excluded during the hardening and breaking process steps and in which the brittleness of the material achieved by the hardening is so high that breaking of the blasting grain to sharp-edged granules is possible with simple means.
- this object is achieved in that the heat treatment at> 900 ° Celsius in reducing atmosphere follows and that a reducing gas or gas mixture is also used for the subsequent cooling.
- the reducing atmosphere is expediently a gas mixture which contains hydrogen and nitrogen.
- a gas mixture which contains 60% to 80% hydrogen and 20% to 40% nitrogen is particularly suitable for the process according to the invention. The best results were achieved with 70% hydrogen and 30% nitrogen.
- a vibrating tube mill is particularly well suited to producing the desired sharp-edged granulate from the hardened starting material.
- the blasting agent For use in the surface treatment of metallic workpieces, it is advisable for the blasting agent to be 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 follow the production process according to the invention. The method according to the invention is explained in more detail below with reference to the drawing.
- the drawing shows a flow diagram of the production process, the upper part comprising 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 fed to the manufacturing process from a scrap store 1.
- carbon in the form of graphite 2 and chromium 3 is added to it from suitable storage containers.
- the raw material mixture is then melted into an alloy in a melting furnace 4. This contains 2.0% carbon and 30% to 32% chromium.
- the melt passes through a atomizing device 5 at a temperature of more than 1420 ° Celsius, whereby granules with a wide range of grain diameters are formed.
- the atomized droplets of the molten metal are quenched in a water bath, so that solid granulate collects on the bottom of a granulation basin 6.
- the granulate is removed from the basin from a fume cupboard 7 and goes through the process steps of draining 8 and drying 9. After passing through cooling 10, the starting material for the rust-resistant chrome cast alloy is available.
- the starting granulate is now fed to a furnace 11, in which it is annealed at more than 900 ° Celsius in an atmosphere of hydrogen and nitrogen 13 at low pressure, 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 elimination of the secondary carbides, which then leads to an increase in hardness to> 60 HRC when the granules cool down from temperatures> 900 ° C.
- the granulate is fed from the container 12 to the crusher 15 by means of a bucket elevator 14.
- the crusher 15 is preferably designed as a vibrating tube mill and comminutes the hardened, brittle granulate into sharp-edged fragments. By using such pulse mills, it is particularly easy to break down the material under strong internal stresses into sharp-edged fragments.
- the grain mixture formed during crushing has a wide size distribution.
- a screening assembly 16 is now run through for classification. Oversize 17 that is too coarse is fed back to the crusher. The undersize 18, which is too fine, is removed from the process at this point and melted in the melting furnace 4.
- Gutkorn 19 with a diameter between 0.1 and 0.8 mm is either stored in a silo 20 or added to the fine classification of a further screening plant 21. Blasting media with different grain sizes are stored in silos 22, 23 and 24 until they are removed for dispatch to the end user.
