Fremgangsmåte for fremstilling av ferrornangan. Procedure for the production of ferrornangan.
Foreliggende oppfinnelse vedrører en fremgangsmåte for fremstilling av karbonfattig ferromangan og ferromangan med middels karboninnhold. Særlig vedrører oppfinnelsen en fremgangsmåte for fremstilling av karbonfattig ferromangan og ferromangan med mid- The present invention relates to a method for producing low-carbon ferromanganese and ferromanganese with medium carbon content. In particular, the invention relates to a method for producing low-carbon ferromanganese and ferromanganese with mid-

Ferromangan fremstilles vanligvis i en elektrisk bue-smelteovn ved en fremgangsmåte som omfatter chargering av mangan- Ferromanganese is usually produced in an electric arc melting furnace by a process which includes charging manganese
malm, fast mangansilicid og brent kalk til smelteovnen hvoretter smeltning og reaksjon av chargen for fremstilling av ferromangan og slagg finner sted. Denne fremgangsmåté kan utføres enten som en éntrinns-forslagningsprosess, hvorved hele chargen blir til- ore, solid manganese silicide and quicklime to the smelting furnace, after which melting and reaction of the charge for the production of ferromanganese and slag takes place. This procedure can be carried out either as a one-step proposal process, whereby the entire batch is

ved først bare en del av manganmalmen og det faste ,ansilicid tilsettes, og den dannede slagg tappes deretter og ^erpå tilsettes resten av chargen. Denne fremgangsmåte lider av den ulempe at den er tidskrevende, den krever omkring 4 timer før den er fullført, og følgelig er slitasjen på den ildfaste .aelteovnsut-foringen meget høy. at first only part of the manganese ore and the solid ansilicide are added, and the slag formed is then drained off and then the rest of the charge is added. This method suffers from the disadvantage that it is time-consuming, requiring about 4 hours to complete, and consequently wear on the refractory lining is very high.
Hensikten med den foreliggende oppfinnelse er å bringe tilveie en fremgangsmåte for fremstilling av ferromangan som kan utføres i løpet av relativt kort tid og som derved i betraktelig grad reduserer slitasjen på den ildfaste smelteovnsforing og med herav følgende besparelse av omkostninger for å erstatte foringen. The purpose of the present invention is to provide a method for the production of ferromanganese which can be carried out within a relatively short time and which thereby considerably reduces the wear and tear on the refractory furnace lining and with the consequent saving of costs for replacing the lining.
I henhold til den foreliggende oppfinnelse går fremgangsmåten ut på fremstilling av ferromangan med lavt eller middels karboninnhold av den art hvor manganmalm, mangansilicid og et kalkholdig materiale bringes til å reagere i en smelteovn, og det karakteristiske ved fremgangsmåten er at kalkstenen eller brent kalk, manganmalm og stålskrap fylles i en oljefyrt roterende ovn, ovnen og innholdet i den forvarmes til en temperatur på fra 1300 til 1600°C, smeltet mangansilicid tilsettes til den forvarmede ovn, ovnen roteres med en hastighet i området av fra 2 til 50 omdreininger pr. minutt under reaksjonsperioden i en viss tid, tilstrekkelig til å muliggjøre fullstendiggjørelse av reaksjonen, og at ferromanganet fremstilt på denne måte tappes deretter fra smelteovnen. According to the present invention, the method involves the production of ferromanganese with a low or medium carbon content of the kind where manganese ore, manganese silicide and a calcareous material are brought to react in a smelting furnace, and the characteristic feature of the method is that the limestone or burnt lime, manganese ore and steel scrap are filled into an oil-fired rotary furnace, the furnace and its contents are preheated to a temperature of from 1300 to 1600°C, molten manganese silicide is added to the preheated furnace, the furnace is rotated at a speed in the range of from 2 to 50 revolutions per minute. minute during the reaction period for a certain time, sufficient to enable the reaction to be completed, and that the ferromanganese produced in this way is then drained from the smelting furnace.
Chargen bør fortrinnsvis være avbalansert på en slik måte at forholdet av manganvekt i malmen og vekten av silicium i silicidet er større enn 2,9. The charge should preferably be balanced in such a way that the ratio of the weight of manganese in the ore and the weight of silicon in the silicide is greater than 2.9.
Malmen bør inneholde minst 47 % mangan. Kalkstenschårgen bør være av en slik vekt at det resul-CaO o terende slagg som tappes fortrinnsvis har et s-forhold på mellom 1,4 og 1,7. The ore should contain at least 47% manganese. The limestone slag should be of such a weight that the resulting CaO slag that is drained preferably has an s-ratio of between 1.4 and 1.7.
Ståltilsetningen bør være tilnærmet 10 % eller mindre av vekten av mangansilicidchargen, den nøyaktige mengde stål til-? satt avhenger av manganinnholdet i mangansilicidet og det ønskede manganinnhold i legeringen man ønsker fremstilt. The steel addition should be approximately 10% or less of the weight of the manganese silicide charge, the exact amount of steel to-? set depends on the manganese content in the manganese silicide and the desired manganese content in the alloy one wishes to produce.
Den tid som er nødvendig for fullstendig reaksjon kan variere fra 2 minutter til 50 minutter, en tid fra 5 til 20 minutter er i alminnelighet tilstrekkelig for å sikre en tilfredsstillende fullstendig reaksjon. Mens reaksjonen finner sted, må smelteovnen roteres med en hastighet som er tilstrekkelig til å sikre tilfredsstillende blanding av chargen, hastigheter i området av 2 til 50 omdreininger pr. min. er i alminnelighet tilfredsstillende for dette formål. The time required for complete reaction may vary from 2 minutes to 50 minutes, a time of 5 to 20 minutes being generally sufficient to ensure a satisfactory complete reaction. While the reaction is taking place, the furnace must be rotated at a speed sufficient to ensure satisfactory mixing of the charge, speeds in the range of 2 to 50 revolutions per minute. my. is generally satisfactory for this purpose.
I løpet av den tid smelteovnen roteres kan fast mangansilicid, manganmalm eller stål tilsettes chargen hvis ønskelig. During the time the furnace is rotated, solid manganese silicide, manganese ore or steel can be added to the charge if desired.
Mangansilicidet som benyttes i prosessen bør fortrinnsvis inneholde fra 17 til 25 vektprosent silicium og mer enn 60 vektprosent mangan. Hvis ønskelig kan en del av kalkstenen eller den brente kalk i den opprinnelige charge erstattes med rå eller brent dolomittsten. - The manganese silicide used in the process should preferably contain from 17 to 25 weight percent silicon and more than 60 weight percent manganese. If desired, part of the limestone or burnt lime in the original charge can be replaced with raw or burnt dolomite stone. -
Karboninnholdet i det fremstilte ferromangan avhenger først og fremst av siliciuminnholdet i mangansilicidet. Mangan-silicider som har et siliciuminnhold på fra 17 til 18 vektprosent resulterer i fremstilling av et middels karbonferromangan, dvs. ett som har mindre enn 1,5 vektprosent karbon, mindre enn 1,5 vektprosent silicium og mer enn 75 vektprosent mangan, mens man-gansilicider som har et siliciuminnhold på fra 18 til 25 vektprosent resulterer i fremstilling av et karbonfattig ferromangan, dvs. ett med mindre enn 1,0 vektprosent karbon, mindre enn 1,5 vektprosent silicium og mer enn 75 vektprosent mangan. The carbon content of the produced ferromanganese depends primarily on the silicon content of the manganese silicide. Manganese silicides having a silicon content of from 17 to 18 weight percent result in the production of a medium carbon ferromanganese, i.e. one having less than 1.5 weight percent carbon, less than 1.5 weight percent silicon and more than 75 weight percent manganese, while -gansilicides having a silicon content of from 18 to 25 weight percent result in the production of a carbon-poor ferromanganese, i.e. one with less than 1.0 weight percent carbon, less than 1.5 weight percent silicon and more than 75 weight percent manganese.
Den foreliggende fremgangsmåte muliggjør.at reaksjonen mellom mangansilicid og de andre komponenter i chargen kan fullfø-res i løpet av relativt kort tid hvilket i høy grad reduserer ned-brytningen av den ildfaste smelteovnsforing og derved muliggjøres betraktelige besparelser i omkostningene ved erstatning av foringen. The present method makes it possible for the reaction between manganese silicide and the other components in the charge to be completed within a relatively short time, which greatly reduces the breakdown of the refractory furnace lining and thereby enables considerable savings in the costs of replacing the lining.

EKSEMPEL 1. EXAMPLE 1.
Malmen og kalkstenen og 11 kg stålskrap ble forvarmet over en periode på l*s time i en roterende smelteovn til en temperatur på 1500°C til 1550°C (optisk pyrometeravlesning). Smelteovnen rotertes ved 3/4 omdr. pr. min. under forvarmningsperioden. Etter at smelteovnen og innholdet var blitt forvarmet, tilsattes 114,4 kg smeltet mangansilicid med en temperatur på 1400°C og smelteovnen rotertes derpå i 7 minutter ved 18 omdr. pr. minutt. Rotasjon av smelteovnen ble så stoppet og produkt og slagg ble tappet fra smelteovnen. The ore and limestone and 11 kg of steel scrap were preheated over a period of l*s hour in a rotary smelting furnace to a temperature of 1500°C to 1550°C (optical pyrometer reading). The melting furnace was rotated at 3/4 revolution per my. during the preheating period. After the furnace and its contents had been preheated, 114.4 kg of molten manganese silicide was added at a temperature of 1400°C and the furnace was then rotated for 7 minutes at 18 rpm. minute. Rotation of the melting furnace was then stopped and product and slag were drained from the melting furnace.
EKSEMPEL 2 EXAMPLE 2

I dette eksempel ble 119 kg kalksten, 127 kg manganmalm og 9 kg skrapstål forvarmet i den roterende smelteovn i 75 minutter opp til 1550°C, mens smelteovnen rotertes med 3/4 omdr. pr. min. under forvarmningen. Malmen og kalkstenen var av samme sam-mensetning og størrelse som den benyttet i eksemplene 1 og 2. In this example, 119 kg of limestone, 127 kg of manganese ore and 9 kg of scrap steel were preheated in the rotary melting furnace for 75 minutes up to 1550°C, while the melting furnace was rotated at 3/4 revolution per minute. my. during preheating. The ore and limestone were of the same composition and size as used in examples 1 and 2.
114 kg mangansilicid ved 1390°C ble så tilsatt den forvarmede smelteovn og så rotertes smelteovnen i 5 minutter ved 18 omdr. pr. min. Rotasjonen av smelteovnen ble så stoppet og produk-tet pg slagget ble tappet av smelteovnen. 114 kg of manganese silicide at 1390°C was then added to the preheated melting furnace and then the melting furnace was rotated for 5 minutes at 18 revolutions per revolution. my. The rotation of the melting furnace was then stopped and the product from the slag was drained from the melting furnace.
