Definitions
- the invention relates to a method for reducing in particular in the form of pyrolysis products released pollutant emissions from foundries used in foundries Metal casting.
- the invention further relates to metal casting boxes for carrying out the method.
- metal molds or mold boxes become a variety of mostly organic substances released in the form of pyrolysis products. This arise primarily from thermal decomposition of the core molding material and that from metal casting additives used in molding sand. The decomposed and evaporated compounds escape as unburned hydrocarbons, gases, aerosols, smoke or dust.
- the pollutant emissions occurring in metal casting are largely due to the The casting line itself and the cooling line and unpacking point are released, i.e. directly the filling process of the hot liquid metal. Escape when using metal casting boxes the pollutants, for example, through the neck of the two mold halves. A further release of a larger amount of emissions takes place when the hot is removed Shaped goods from the metal mold instead (unpacking point).
- the invention is therefore based on the object, the method mentioned above further train that an effective reduction in pollutant emissions at low Effort is achieved.
- the process should be applicable to all metal molds be independent of the composition and the amount of emissions.
- the invention is therefore based on the idea by adding an additional flammable substance to ensure that then also burn the pollutants.
- the joint combustion of pollutants and the flammable substance is therefore almost independent of the amount and the calorific value of pollutants instead.
- Metal molds generally consist of at least two parts, preferably of two mold halves. At least one of these mold halves, preferably two mold halves, enclose the molding sand, for example one using additives and pressure may be porous sand material.
- the shape of the molding sand determines the outer contour of the later cast material.
- the casting room or several mold cores are added, which then the inner contour and cavities of the Determine castings.
- an organic substance used according to the invention is to be understood as an organic substance, which is preferably a wax or an oil, particularly preferably contains a ketone, an aldehyde, ether, alkane or alcohol.
- This substance is therefore a chemical compound caused by self-ignition or with the help of an ignition flame in the event of gaseous discharge from the molding box and Contact with the outside air burns.
- This substance is added to the metal casting box added to the additives common in metal casting.
- Preferably one has flammable substance has a high calorific value.
- Process flammable substances preferred that only in the presence of Burn ambient air, or it is highly flammable or ignite itself.
- Especially flammable substances are preferred which are first under the conditions of a metal casting when emerging from the metal mold under auto-ignition or with the help of an ignition flame burn.
- a flammable gas can also be used as a flammable substance Find. This can be pressed into the molding sand with the help of injection pipes and is controllable as required. The use of gas is especially with stationary, so not Molds made on the belt - without transporting the container - cheap.
- the combustible substance added to the metal mold mixes in gaseous form with the Pollutants in the metal mold and escapes together with them.
- the pollutants by the heat of combustion according to the invention added additional flammable substance burned with.
- the additional substance is preferably the metal casting boxes in the outer molding sand - added to the pressed molding sand in the area of the attachment edges of the mold halves.
- the additional combustible substance can namely the metal mold evenly or added locally concentrated.
- the place of addition should depend on the design of the metal mold be chosen so that a good mixing with the pollutants in the Gas phase succeeds, for example along gaps or channels provided for this purpose can flow in the molding sand or the outer mold itself.
- Direct contact with the additional flammable substance with the liquid, hot cast goods must be avoided, because this would generate a strong spontaneous pressure wave.
- Process no influence on existing, optimized molding techniques and / or Materials are taken.
- the addition of the additional has therefore proven to be particularly advantageous Proven fuel only after pouring the liquid metal into the mold. Even a small spread of the additional fuel - gaseous or liquid - This makes the contact area of the cast goods impossible. Always one in the cooling process given gas movement - directed away from the casting - prevents influence the additional substance.
- an advantageous optimal dosage of the additional substance take place.
- the quantity / type the substance and its local positioning as well as the time of addition can be a for optimized pollutant combustion throughout the emission period.
- At least one additional flammable substance in front of the attachment edge of the mold and / or in front of at least one outlet opening of the mold is positioned.
- the amount of flammable substance to be added depends on the dimensions, the structure and composition of the respective metal mold. In addition to positioning in the metal casting box also determines the amount of substance and the composition the substance the extent of combustion of the released pollutants.
- At least such an amount of additional combustible substance is in the mold added that a combustion of the pollutants at least during one Part of the cooling phase of the casting process, preferably until the mold opens, especially is preferably guaranteed until the cast goods are detached.
- An additional addition of fuel which is by means of a penetration, is particularly preferred of the entire molding material - when the casting box is broken open to remove it the cast goods - a complete combustion of all stored pollutants in the Molding sand guaranteed.
- the entire molding sand burns openly with a large Surface.
- a second or repeated addition / injection can also be carried out of fuel can be carried into the mold.
- Any compound or a mixture of compounds can be used as a combustible substance are used which are combustible and flammable under the conditions of a metal casting process is.
- a large number of such compounds or mixtures are known to the person skilled in the art known that at the higher temperatures and environmental conditions in the metal casting box and / or at the edge of the neck during escape and contact with atmospheric oxygen have the required properties.
- the additional flammable substances used in the process preferably contain Substances at least one organic substance, preferably a wax or an oil, particularly preferably a ketone, an aldehyde, ether, alkanes or alcohol.
- Flammable substances with a boiling point between 20 ° C are preferably used and 200 ° C, particularly preferably substances with a boiling point between 50 ° C and 100 ° C.
- substances which have low odor are of course preferred and burn connections that are harmless to health. Most preferably these are gas mixtures that burn to carbon dioxide and water.
- the added substances can be, for example, as a solid, but preferably as Liquid is present when added to the metal mold. It is particularly favorable if the Substances are present as a liquid when added to the metal casting mold and evaporate / boil, when the hot metal or hot exhaust emissions convey heat.
- the conversion of the combustible substances into the gas phase is preferably carried out by Thermal bridges on the part of the hot cast goods are conveyed via the molding sand.
- the substance evaporates due to the hot pollutants that are formed during the casting process and burns preferably only when mixed with the pollutants at the exit the mold and contact with air.
- the combustion of the substance / pollutant mixture can also only take place upon contact with a pilot flame.
- the invention further relates to a metal casting box which is used to carry out the invention Procedure is modified. It has proven particularly favorable if the metal casting box consists of at least two mold parts, in which at least one of the halves in the attachment edge has a groove as an outlet opening for gases. Also channels and holes in the molding sand that facilitate the removal of the gases, can be provided in an advantageous manner.
- gas guides are provided within the molding sand are, which open into an outlet opening.
- At least one of the two mold halves has a recess in the molding sand for receiving flammable substances.
- the dashed line shows the course of the total mass of hydrocarbons in the Exhaust air, after a short mixing with the outside air and its partial (Fig. 1) or complete Combustion (Fig. 2).
- An exemplary measuring point is indicated in FIG. 3 at point 8.
- the Y axis shows the mass of the pollutant quantity.
- time t0 becomes liquid Put metal in the metal mold and ignite the pollutants at time t1 triggered.
- time t2 the combustion has ended because of the relatively low emission of pollutants further combustion is no longer possible.
- the integral of the area below the dashed line is a measure of the still large one Amount of pollutants emitted.
- adding a combustible substance increases the level the hydrocarbon emission on the Y axis.
- liquid iron is placed in the metal mold and one occurs Autoignition of the pollutant / substance mixture at time t1.
- the burning process is ended late, at time t2. Then the amount used is additional combustible substance almost completely consumed.
- a part of a molding box 1 is shown.
- the cast goods 3 lie in the molding sand 2.
- the increasing blackening in the area of the cast goods is intended to indicate the temperature profile.
- the additional combustible substance 4 is in the vicinity of one Gas outlet opening (e.g. in the area of the attachment edge of the two halves of the molding box 1.
- the flow lines 5 shown show that a mixing of the gasified fuel takes place with the harmful gases of the cast goods 3. This gas mixture escapes in the area the attachment edges of the two halves of the molding box 1 in the direction of arrow 6 to the outside and reaches the point at which the total emission shown in FIGS. 1 and 2 is present.
- Fig. 4 shows an example of various addition options for combustible Substance 4 in the casting box 1.
- the additional one is Substance 4 is stored in partial areas of the molding sand 2, namely by injection or storage before assembly of the halves of the molding box 1 on both sides of the Dividing line 9 or by injection after casting.
- the combustible substance 4 can be poured in in only one half or storage in partial areas of the molding sand 2 before the assembly of the box halves be stored.
- 4C illustrates a further possibility, according to which the combustible substance 4 is embedded in partial areas of the molding sand 2, namely after casting by means of injection in the molding sand.
- the additional combustible substance is 4 always stored separately from the cast goods 3, in such a way that they do not have their surface reached. Regardless of which of the three storage options is chosen, it acts is always a storage that ensures that the substance without causing decomposition only by heating with the resulting evaporation / boiling from the Form is pushed out without pyrolysis taking place.
- the substance can be stored in the molding box so that it is heated distributed in gaseous or vaporous form with the aim of opening the Casting the mold together with the pollutants and burning it (unpacking point).
