Definitions
- the invention relates to a pig casting machine according to the characteristics of the Preamble of Claim 1.
- the invention relates to the use of a such a casting machine.
- Liquid pig iron is known to be either after tapping in the Blast furnace fed to the steelworks by means of pans or, if not immediately can be further processed in the form of ingots, so-called ingots Shed storage or for further transport.
- ingots Shed storage or for further transport Have pig iron pigs different weights, usually depending on the intended use a pig weighs about 6 kilograms.
- Pig casting machines are used to produce pig iron. These traditionally consist of a casting station, at least an endless conveyor belt and an emptying station at the first Deflection point of the endless belt. On this endless conveyor belt are mostly a variety of thick-walled molds arranged. The respective mold is filled with molten pig iron at the casting station. The conveyor line of the ingot casting machine must then extend so far that the liquid Iron in the respective ingot mold before reaching the first deflection point of the endless conveyor belt is solidified and the shrinkage is loosening from the Mold favored. As they pass through the deflection point, they empty Casting molds automatically, or the pigs are made using an appropriate Device released from the molds. The ingot molds or molds are more well known Pig casting machines are made of cast iron. About the process of solidification To accelerate the liquid iron, the molds become sideways and additionally cooled with splash water from above.
- FR-A-1 053 147 describes a ingot casting machine for casting Light metals or their alloys, especially aluminum.
- the single ones Pig casting molds are formed from sheets or plates of rolled steel, two sheets forming the long sides of the mold and another sheet forms the bottom of the mold, which can also be wavy can. No baskets are disclosed.
- DE 114 428 C discloses a casting plant with an endless mold chain, which is used for the production of pig iron.
- the ingot forms exist completely Made of fireproof material, a metal for attachment to the link chain Have coat. It is therefore the combination of pig iron as something to be cast Metal and refractory (ceramic) ingot molds disclosed.
- the Mess form is completely absorbed by the coat in close contact.
- German patent DE 809 948 is a pig casting machine for Casting light metals and their alloys with correspondingly low Melting points known, the ingot casting molds as an endless belt are arranged. It is suggested to use the ingot shapes instead of cast iron form from a forged metallic material, for example made of copper or aluminum or steel. It is described that it is based on this Is possible to get by with relatively thin-walled pig shapes, as they are directly cooled with water before, during and after watering can be, for example, by spraying from below.
- the invention is based on the object to provide a pig casting machine with thin-walled Ingot casting molds, which are excellent with good shape stability have cooling effect.
- the invention is based on the knowledge confirmed by tests that it The cooling of the ingot molds makes it possible, completely different from the decades retained casting of only light metals with a low melting point for casting heavy metals with Melting points above 1,000 ° C to use such casting molds, which are made of a heat-resistant material whose melting point even lower or not significantly higher than the respective melting point of the metal to be shed.
- the known capacitive cooling is the case; rather prevents areal Cooling their melting.
- the metal melts to be cast it is particularly heavy metals, such as pig iron, the is usually cast at temperatures between 1450 and 1520 ° C.
- the ingot molds are preferably made of copper, whose melting point is at 1083 ° C. But they are also materials with significantly lower thermal conductivity conceivable, for example heat-resistant steel, whose melting point - depending on its carbon content - around 1520 ° C lies.
- the criteria for the material of the ingot shape can be based on other essentials Properties are placed, in particular on the cold or Hot formability properties that determine the suitability for Rolling and preferred subsequent deep drawing, which is an inexpensive Manufacturing allowed, as well as the mechanical properties at elevated temperature, those for the shape stability of the casting mold in use and its insensitivity against cracks.
- a preferred proposal of the invention therefore provides that the thin-walled primary material for the ingot casting molds manufactured by rolling and then, for example, deep-drawn or is formed by die pressing.
- the Support baskets are designed so that they are only partially in support contact with the casting molds are.
- the inner contour of the support baskets is approximately adapted to the outer contour of the ingot casting molds, and also the inner surface the support baskets with support pins for selective support of the thin-walled casting molds, preferably the diameter of the support pins on Carrier basket should not be larger than the wall thickness of the ingot shape. It will thus both the requirements in ensuring adequate Dimensional stability of the thin-walled pig shape as well as due to the only selective support of the still unimpeded cooling is sufficient done.
- the carrier basket can also be designed as a lattice basket, which is the respective ingot mold supports like a net.
- the execution and the material for the support means are chosen so that they have a low elastic deformation do not counteract the shape of the pig because of the weight of the pig. Due to this elastic deformation and thus little expansion the form supports the removal of the ingot at the emptying station.
- the carrier basket itself can have rollers that run along guide rails to run.
- the basket is over corresponding Holding means suspended in two parallel chains.
- the support basket With the support basket it is possible to cover the wall of the respective casting mold train very thin. Have molds with thin walls the advantage that the risk of cracking due to thermal stress is minimized. With decreasing wall thickness, the form stability decreases, whereby this disadvantage is compensated for by the supporting effect of the carrier basket. Due to the partial support by means of the support pins or the grid is a cooling of the ingot molds and thus the casting Spraying or immersing in a bath is not significantly hindered. at Carrying basket with support pins should be the diameter of the Support pins on the carrier basket correspond at most to the wall thickness of the ingot shape, so that the cooling at the points of application of the support pins is not impaired becomes. Overall, a stable ingot mold with cheap Cooling properties provided. The melt solidifies faster, the circulating speed of the endless belt can be increased and thus the amount of melt spilled per time interval.
- the belt can be shorter and at an unchanged rotational speed then run cheaper.
- the overlap area of the To provide the edges of adjacent casting molds with refractory material preferably the hot-mold edge area in the overlap area is molded in such a way that a recess for receiving the refractory material arises. Starting from this recess are anchoring means intended for the refractory material.
- the ingot molds are made of one Composite layer material made, with a material for the hot-side layer is chosen whose melting point is higher than that of copper, in particular a heat-resistant steel, and for the cooling-side layer the highly conductive and crack-resistant copper is chosen.
- the composite material is preferred produced by roll or explosive plating with subsequent forming, for example, by deep drawing, die pressing or the like.
- the wall thicknesses of the ingot casting molds should range between 3 to 20 mm and the ratio of the weight of the pig shape to the weight of the pig are in the range between 0.5 and 2.
- Conventional cast iron pots where only the heat dissipation through the metal wall (so-called capacitive Cooling) is used, in contrast, have a weight ratio Cheating form / cheating from much larger than 1 to typically 6.
- a pig casting mold comprises a plurality of individual tundishes or mold troughs.
- the ingot casting molds can also have a cuboid floor surface or cuboidal tundishes, which is a great advantage in production which means molds.
- the ingot molds are short before, during and after the casting process until the solidified pig is ejected cooled from below, preferably by spraying cooling water on the surface or a water-air mixture.
- the spray nozzles can vary depending on the location required cooling capacity must be arranged densely or less densely.
- In the Spray cooling evaporates most of the sprayed water on the underside the slang forms.
- Unevaporated dripping water is in a gutter captured and reused.
- the gutter also forms part of one Enclosure for suction and, if necessary, condensation of the resulting water vapor.
- An additional cooling device between the emptying station and the casting station is possible, but because of the low storage heat Thin-walled pig shapes are not absolutely necessary.
- the endless belt should not be like known in conventional designs, with an upper and lower run, but be arranged horizontally in the manner of a carousel.
- a cooling device in the form of spray nozzles and / or a cooling water sump are arranged so that they are just before start the pouring station and extend to the emptying station.
- the diving tank may also come with the water collecting tank for the dripping water or the condensed water in question. Overall, when using this Design reduced the number of ingot casting molds used, and the Optimized time utilization.
- the ingot molds are proposed as a preferred embodiment to be double-walled and to be cooled by means of continuous water cooling.
- a ring distribution line is proposed in the carousel arrangement, according to the ingot molds in a horizontal carousel arrangement rotates and from a rotating pipe in the center of the Carousels is fed, the ring manifold having hoses that in turn feed cooling sections that are in the spaces of the double wall trained ingot molds.
