Definitions
- the invention relates to a metallurgical vessel, in particular a converter for the treatment of liquid metal melts, consisting of a refractory lining and a supporting metal jacket surrounding it, according to the preamble of claim 1.
- Metallurgical vessels such as B. Converters or steelworks pans are exposed to the static load from the weight of the lining and the filled molten metal also to a thermal load due to the high temperatures.
- the supporting metal jacket of these vessels must therefore be made of a material that has a certain creep rupture strength, for. B. for 100 000 h based on a predetermined temperature.
- the maximum temperature that can be tolerated is 400 ° C.
- the increasing secondary metallurgical treatment e.g. B. vacuum treatment
- a higher melting temperature to compensate for this temperature loss.
- the aim is a tolerable temperature of 500 ° C., preferably 550 ° C.
- heat-resistant steels are known that are suitable for this temperature range, for example 15 Mo 3, 13 CrMo 44 or 10 CrMo 9.10.
- all these steels have the major disadvantage that after welding, the component has to be stress relieved at a temperature of around 700 ° C.
- the object of the invention is to provide a metallurgical vessel of the generic type, the load-bearing metal jacket of a sufficient creep resistance up to max. 550 ° C and which requires no stress relief annealing after welding.
- Wall thicknesses are sometimes required for the intended use. Usually, the known fine grain steel for sheet thicknesses up to max. 50 mm.
- the metallurgical vessel designed according to the invention is explained in more detail using the manufacturing method. Show it:
- Figure 2 is an external view of Figure 1
- FIG. 1 shows a longitudinal section of a converter 1 produced according to the invention.
- This has a metal jacket 2 composed of a plurality of sections 6, 7 and dome parts 8, a foot ring 3 arranged on the bottom and a muzzle ring 4 arranged on the upper edge.
- Refractory material 5 is arranged within the metal shell 2, the thickness of which decreases with the travel time of the converter 1 as a result of burning and washing out. The decreasing insulating thickness of the refractory material leads to higher temperatures in the metal jacket, which must be endured in the long run.
- FIG. 2 shows an external view of the converter 1 shown in FIG. 1.
- a steel melt is treated with calcium and vacuum before pouring and then shows the following actual analysis in percent by weight.
- This molten steel is cast in a continuous casting process to form a slab with a thickness of 260 mm and a width of 2300 mm. After cooling and
- the slab is rolled out in several passes from a sheet with a thickness of 80 mm and a width of 2900 mm and a length of 6000 mm.
- the individual shape change 8 h in the individual stitches is greater than 0.1.
- the heavy plate produced in this way is subjected to tempering, consisting of heating to an austenite temperature of 920 ° C with subsequent water quenching. This heat treatment can be repeated depending on the requirements for fine grain. Finally, it is tempered at 700 ° C with subsequent cooling in air. After tempering, the heavy plates are cut to the required bending dimensions. This is followed by bending into shells
- the otherwise required stress relief annealing after welding can be omitted according to the invention.
