Definitions
- the present invention relates to the use of iron mica for the production of casting molds, in particular lost casting molds, and cores for the casting of castings from non-ferrous, cast iron and cast steel alloys and mixtures of iron mica containing molding materials.
- iron mica can also be used as an additive for coatings for molds and cores, used in the entire field of the foundry industry, and as an additive for exothermic food aids.
- a lost mold is a sand mold, solidified by organic or inorganic binders (e.g. clays, resins) which can only be used once and must be destroyed after casting to empty the castings.
- organic or inorganic binders e.g. clays, resins
- Cores have the task of forming cavities or undercut external contours in the cast part. According to their usability, a distinction is made between cores for single use (lost cores, sand cores) and permanent cores (metal cores), which are used repeatedly. Sand cores are separately manufactured inner mold parts. They are inserted, inserted or hung into the outer mold parts when assembling the mold. A large percentage of both lost molds and lost cores are used in the foundry industry today mainly because they can be manufactured relatively inexpensively and the mold material can be reprocessed after the molds have been destroyed and reused to produce new molds.
- Finishing or blackening are refractory materials that are used in liquid or pasty form to produce a thin coating on the mold walls or cores (sand cores, metal cores) and have heat-insulating, heat-conducting, smoothing, separating or blocking effects.
- mold material coatings are refractory materials that are used in liquid or pasty form to produce a thin coating on the mold walls or cores (sand cores, metal cores) and have heat-insulating, heat-conducting, smoothing, separating or blocking effects.
- Suitable and suitable additives are mixed with these coatings.
- the molds required for the production of cast products in the casting process are made with molding materials that consist of binder (organic or inorganic), molding material, water and molding material additives. These terms are explained in more detail below:
- a mold is to be understood as all molds for the production of cast products, such as Sand mold, mold, die casting mold, ceramic investment mold or shell mold. Only as examples are outer and inner mold parts, box molds, boxless molds, core molds and mask molds.
- Molding material is the collective name for all dry, moist, pasty or liquid substances for the production of casting molds that are compacted, solidified or bound by chemical processes, e.g. Mold and core sands, flow sands, form slips and ceramic molding compounds.
- Mold base materials are natural mineral or synthetic granules or sands, which are used for the production of molds for single use.
- Binder is understood to mean components of molding material which, under certain conditions (.wetting, swelling, silicate formation, polymerization, etc.), create the bond between the individual grains of sand.
- swelling binders e.g. bentonites, which swell when adding a mixing liquid
- ceramic binders e.g. alumina, which solidify through drying or sinter in the heat
- hydraulic binders e.g. gypsum or cement, which react with a harden
- chemically hardening binders e.g. water glass, ethyl silicate or synthetic resins
- molding material means an addition to binder-containing molding or core sand mixtures, which - 3 -
- Improve shafts and / or affects the interaction between molding material and casting metal examples include glossy carbon formers, starches, calcined soda, boric acid, and wood and peat flour.
- Defects occurring in castings can be caused by the molding material (molding defects caused by the molding material), or also metallurgically (microporosity, inclusion of slag, perspiration pearls, shrinkage and stress cracks, segregations etc.) or technologically (offset, cold casting, dimensional inaccuracy etc.).
- Iron mica mentioned here is described in ISO 10601 (first edition 1993-08-15), the sieve residue of max. However, 0.1% on the 105 ⁇ m sieve is expressly excluded.
- Iron mica - CAS No. 1317-60-8 - also means iron oxide (alpha-haematite), which has a higher sieve residue.
- iron oxide (according to ISO / DIS 1248.2) - mostly as iron oxide red - as a molding material additive is known and is considered "state of the art". These are powdery, mostly amorphous, iron oxides of high fineness. The usual additional quantities are approx. 0.5-1%.
- Iron mica is dark gray in color with a metallic sheen. Mica shows a platelet-shaped, lamellar structure and is therefore different from natural and synthetic iron oxides. For both products, the chemical composition with Fe 2 0 3 applies in pure form.
- iron oxide iron oxide red
- expansion errors of the sand structure in the casting heat are partially suppressed and the casting quality is improved.
- These additives especially with higher additions, have a negative impact on the strength properties of the molds and cores to such an extent that sufficient shape stability is no longer guaranteed and the casting or the handling of the molded parts or cores is no longer possible.
- the molding material mixture used to produce the molds and cores being 4 to 90% by mass, preferably 4 contains up to 50% by mass, in particular 4-20% by mass, of iron mica as a molding additive.
- mica is intended for the production of coatings (finishing / blackening), the proportion of mica being 0.1 to 10% by mass in the solid mass of the coating.
- Molded material coating is liquid or pasty and, depending on the carrier used, contains less iron mica.
- the iron mica used according to the invention does not have the negative properties of iron oxide red.
- the main cause of this effect is its platelet-shaped, lamellar structure, which also makes it possible to increase the percentage in the respective molding material mixture compared to iron oxide (iron oxide red) without negative effects on the strength properties of the mold / core.
- Typical casting defects such as leaf ribs, mineralization, pinholes etc. are significantly reduced, the surface quality is improved and the microstructure, especially with AlSiMg alloys, taking into account a high packing density of the molding material / iron mica mixture is greatly refined. As a result, better mechanical properties, savings in subsequent heat treatment and lower cleaning costs can be expected.
- GT quartz sand
- 10 GT iron mica based on 6% bentonite and 3.5% water
- GT glass transition temperature
- the wet tensile strength was 0.22 or 0.20 N / cm 2 , the compressive strength - 6 - strength 16.9 or 19.2 N / cm 2 . Since the higher compressive strength of the mixture with a higher proportion of iron mica is due to the higher bentonite content, a higher bentonite content is also recommended for iron mica contents> 20%. Basically, the properties of the molding material mixtures are not negatively influenced by the addition of iron mica from a casting technology point of view, but the rate of heat removal is significantly improved, i.e. faster additions of iron mica in connection with a dense packing can be expected to cool down / solidify more quickly.
- iron mica as an additive for exothermic food aids is provided according to the invention. Because of the surprising, highly insulating effect of iron mica as a pure, binder-free substance, such use of iron mica is particularly advantageous. Suitable addition amounts are about 0.1 to 20% by mass of iron mica.
- Fig. 7 Cooling curves of G-AlSi7Mg when using molding material mixtures with 10 or 20% mass of iron mica additive with normal compression (M10N or M20N); as a comparison quartz sand mixture without additives (Q1N),
- thermocouples used (they consist of two wires of different metals which are welded at the ends) generate electricity by heating the welding point of the "thermocouple". This thermal voltage is a measure of the temperature at the measuring point. Depending on the time, there are cooling or heating curves.
- the thermocouple pairs used consisted of platinum-platinum-rhodium with a temperature range from 0 to 1300 ° C and a thermal voltage of 10.5 ⁇ V / K. - 8th -
- the basic form 1 consisted of water glass / C0 2 hardened quartz sand, in which a copper tube 2 (diameter 30 mm, wall thickness 1.5 mm) was placed exactly in the middle. This copper tube serves as the actual shape for the cast material 3; The substance to be measured was then either poured into the area around the copper pipe or compacted in a defined manner as a mixture of molding materials. Thermocouples 5 were used at suitable locations.
- Copper was used because this material has a very good thermal conductivity, which means that the casting heat is well transferred to the granular substances or molding material mixtures to be examined. At the same time, however, the thermal stability should be so great that the copper form does not melt and, especially when measuring the loose, pure granular substances, a form stability is guaranteed until the end of solidification.
- the size ratios are selected so that both a constant mold compression (e.g. only by the bulk density of the pure substances) and a sufficiently sensitive measurement of the temperature gradients is possible.
- thermophysical parameters of the materials used are an absolute prerequisite for the computer simulation, which are not available for iron mica and With these investigations, data from zircon, chromite and quartz sand were used.
- Quartz sand 138 sec. - 9 - show the necessary sensitivity of the test facility used.
- Shorter solidification times are synonymous with good heat removal properties of the molding material and thus with good structural and casting properties.
- thermocouples 5 are located in the thermal center of the casting material (GG, G-AlSi7Mg) and in the granular material or in the molding material mixture 20 mm from the metal / mold interface and are constant in all tests. All measurements were taken at a rate of one value per second until the end of the test.
- the properties of bentonite-bonded molding material are not adversely affected by iron mica additives. A significant increase in the amount of binder is not necessary.
- the heating curves of the molding material mixtures during solidification shown in Fig. 8 show the same tendency as in Fig. 6, but the curve is different due to binder components and water addition.
- the solidification times of the light metal alloy G-AlSi7Mg measured here are as follows:
- Quartz sand mixture - Q1N 102 sec.
- G-AlSi7Mg The solidification time of G-AlSi7Mg is the lowest with 20% iron mica addition and highly compressed forms (Fig. 11).
- - 13 - Mix I high density (MIOH) was compared to mixture II high density (M20H) and the normal quartz sand mixture (QIN) and the solidification rates were measured. They are in G-AlSi7Mg for:
