Definitions
- the invention relates to a method for casting a steel having a chromium content of more than 15 percent by weight, in particular more than 33 percent by weight.
- High-temperature-resistant and wear-resistant steels with a high chromium content and carbon-containing alloys have hitherto been produced as individual parts in a discontinuous sand casting process.
- the cast product is then mechanically processed directly without additional thermomechanical treatment.
- liquid steel is fed by means of a feed system with a correspondingly formed nozzle onto a circulating transport belt cooled from below with water.
- the conveyor belt is driven and guided by two pulleys.
- the melt applied to the conveyor belt solidifies completely in the area of the primary cooling. After solidification, the strip enters inline rolling in rolling stands. After inline rolling and another cooling process, the tape is rewound.
- Such a casting method for strip casting is known from DE 198 52 275 A1.
- WO 02/064288 A1 also discloses a method and a device for casting and solidifying liquid metal and its division, which is intended in particular for ferroalloys or non-ferrous metals and for their division.
- endless strips of predeterminable thickness are produced from the liquid phase by the use of a strip casting plant.
- a crushing plant divides these into pieces, wherein in the surface of the bands during casting and solidification, a pattern of predetermined breaking points is impressed, which determines the predefined, optimal size of the product pieces when breaking the tape.
- selected components for example bearing sleeves for turbochargers
- this object is achieved in a method of the type mentioned in that the steel is poured in a horizontal strip caster.
- the invention is particularly suitable for casting a steel which additionally has a carbon content of more than 1 percent by weight.
- the strip casting method is advantageously used if the steel additionally has a silicon content of more than 2 percent by weight. It can be provided that the cast steel strip or casting plates produced by casting are cut, milled, drilled or annealed.
- the invention also relates to a horizontal strip casting plant for carrying out the method explained above.
- the strip casting plant is characterized in that it comprises a melting furnace, a ladle and a conveyor belt for receiving and cooling a flowing out of the ladle liquid steel.
- the invention thus aims at the use of a horizontal Bandgit- device for the production of building or insert parts from, for example, high-alloy tool steels from whose dimensions match the cast strip thickness in horizontal strip casting, so that a hot rolling with the goal of recrystallization or thickness reduction is not necessary is.
- the blanks can be cast continuously, and the creation of single-shot molds, as in sand casting, is eliminated.
- the conveyor belt is equipped with recesses for the formation of cast iron plates within the steel strip or with transverse projections for the formation of predetermined breaking points within the steel strip.
- the strip caster may be associated with other equipment for the mechanical aftertreatment of cast by the conveyor belt casting plates. These are, for example, cutting devices for the exact definition of the width and the length of the cast blanks which already have dimensions close to their final dimensions during the casting process. Alternatively, the cast semi-finished product is processed by various mechanical methods to obtain the desired final dimensions.
- a separating or cutting device for severing the cast product is arranged downstream of the conveyor belt in the conveying direction.
- 1a, b is a schematic side view and a plan view of a plant for strip casting according to a first embodiment
- FIGS. 2a, b show a side sectional view of a conveyor belt for pouring cast platelets and a plan view of the conveyor belt, with which cast platens of different dimensions are cast side by side, and
- the outlet nozzle 4 has a width which corresponds to the width of a casting plate 7 to be cast on the revolving conveyor belt 5.
- the conveyor belt 5 is driven and guided by two deflection rollers 10, 11 each equipped with its own drive 8, 9.
- the conveyor belt 5 passes through the container 13 of the cooling device 6, which may also comprise further devices for cooling the circuit board 7.
- the two deflection rollers 10, 11 can each flow through a cooling liquid.
- a spray cooling device 14 which sprays the conveyor belt 5 from the bottom with a cooling liquid.
- a board 7 pour, the length of which corresponds approximately to the length of the system 1 or beyond its length.
- the casting board 7 either already has the desired length resulting from a determination of the amount of liquid steel in the tundish, or it is separated by means of a cutting or crushing device 15 after leaving the conveyor belt 5 and fed to a semi-finished stock 16. From there, it is forwarded for further treatment, for example milling, drilling, annealing or further cutting or other machining processes, to the corresponding devices and devices. Since the board 7 already having the desired thickness, it does not need to undergo a rolling process as a thermomechanical treatment process. However, depending on the desired material properties, a rolling process may also be provided as a treatment step to the casting process, either immediately after this or after the castings have cooled.
- a conveyor belt 17 (FIGS. 2 a, b) has a plurality of depressions 19 in a further strip casting installation 18 whose dimensions are close to the final dimensions of the castings to be cast in them.
- the recesses 19 are either only one after the other or depending on the width of the conveyor belt 17 additionally arranged side by side. The dimensions of the adjacent recesses 19 may have different dimensions.
- a plurality of outlet nozzles 20 Corresponding to the number of rows of depressions 19 mounted next to one another on the conveyor belt 17, a plurality of outlet nozzles 20 having a width adapted thereto are also provided.
- Casting can be used to produce castings of various thicknesses; Usually, the casting thickness is between 8 and 25 mm, preferably 15 mm.
- Typical applications of the high-alloy material are bearing sleeves, for example, the dimensions of 13 mm (thickness) x 120 mm (length) and are made by machining of castings, for example, with the thickness 15 mm and the same width on a lathe, wherein the hollow cylindrical Form is produced by drilling out of the core. All other forms are obtained by machining superficial material of the castings.
- the casting geometry is 15 mm (width) x 125 mm (length); this results from mechanical, in particular Machining, machining a component geometry of 12.7 mm (width) x 120 mm (length).
- this preferably also contains carbon of more than 1 percent by weight and / or silicon of more than 2 percent by weight.
- the property profile of the castings to be cast with the strip caster 1 or 18 includes good high temperature resistance combined with good wear resistance.
- the Rockwell hardness (HRC) is 33 to 38 at a tensile strength of about 1000 MPa.
- HRC Rockwell hardness
- the process-typical rapid cooling has positive effects on the microstructure of the castings. Grain size is reduced and precipitates, such as carbides, are finely dispersed in the matrix due to the impeded diffusion. This results in advantageous mechanical properties.
- various possibilities of temperature control for cooling the castings (Fig. 3a - d).
- a first procedure (FIG. 3 a)
- the temperature of the cast products is initially held for a predetermined time and then cooled off at a defined cooling rate (curve 21).
- a heating phase may also follow (curve 22).
- the castings are not cooled until later.
- the cast products are heated to a defined temperature immediately after casting (FIG. 3b) and only then cooled for a predetermined period of time at a predetermined cooling rate.
- the castings are directly through Quenching rapidly cooled ( Figure 3c) and then subjected to a controlled temperature control over time, as far as they have not yet assumed the ambient temperature by the quenching process.
