摘要： With the process for the production of iron from an iron-oxygen combination, preferably ore, the iron-oxygen combination is essentially reduced in an ore reduction vessel with a reaction gas from a melting crucible, then supplied to this melting crucible and melted by adding carbon-containing fuels and oxygen-containing gases.According to the invention, the reaction gases escaping from the melted iron are partially subjected to after-burning in the melting crucible. The thus developing heat is largely transmitted to the melted material and the reaction gases are cooled and reduced with reducing agents on their way to the ore reduction vessel.

摘要： A procedure is provided for producing steel from solid, iron containing pieces such as scrap iron, solid pig iron, iron pellets, iron sponge and the like. The iron containing pieces are smelted in a blown oxygen converter equipped with submerged injection devices for oxygen and pulverized fuel. The pieces are first introduced into the converter and preheated and then they are contacted with a sufficient quantity of molten steel to substantially reduce the length of the smelting period and thereby conserve fuel. The molten steel used in the contacting step is recycled from the previous batch after having been retained for the meanwhile in a separate auxiliary ladle.

摘要： To gain electric energy in addition to producing molten pig iron, from lumpy iron ore and solid fuels, by using a direct reduction zone for the reduction of the iron ore to sponge iron and a meltdown-gasifying zone for the production of molten pig iron, carbon carriers are used in, and oxygen-containing gases are supplied to, the meltdown-gasifying zone. The reduction gas forming is fed into the direct reduction zone. The reduction gas reacted there is supplied as top gas to a power generation plant including a turbine. In order to adapt the power generation to the power consumption by simultaneously avoiding any influence on the metallurgical conditions at the production of pig iron and its further processing, the charge of carbon carriers into the meltdown-gasifying zone is varied as a function of the gas consumption of the power generation plant in a manner that, with a higher gas consumption, the volatile constituents of the charge are increased and the C.sub.fix charge is reduced and, with a lower gas consumption, it is proceeded the other way round, while keeping the amount and composition of the pig iron produced substantially constant.

摘要： In a process for continuously melting scrap (6) and/or pig iron within a converter (1), the converter (1) is heated in proximity of the bottom (3) with sub-stoichiometric burners (4), having their flames (5) essentially radially directed into the interior of the converter (1). In this case, secondary air or O.sub.2 is supplied at a distance above the burner plane for the purpose of completing the combustion. The melt is, optionally together with slag, discharged via a tapping means (9) laterally connected to the converter (1) into a mobile ladle (19). For the purpose of interchanging ladles (19), the converter (1) is swivelled into a position in which the level of the melt is located below the taphole (11).

摘要： For the purpose of melting scrap iron, pelletized sponge iron in reduced condition, solid pig iron or the like, there is introduced into the melting heat from below a charge-accepting receptacle by means of burners the carbon content within the molten bath is adjusted by a sub-stoichiometric combustion of hydrocarbon. Addition of any coal to the charged material is avoided. By reducing the oxygen flow, in particular by performing the combustion with approximately 0.9-times of the stoichiometric amount of oxygen, and by optionally adding slag formers, the aggressivity of the slag in relation to the furance lining is simultaneously reduced.

摘要： A compound steel material of high corrosion resistance is manufactured by alloying a carbon steel carrier material having a carbon content of at most 0.20C and of at least 0.04C with a carbide and nitride forming substance, compounding the alloyed carrier material with a ferritic chromium steel material of normal carbon content, followed by hot-rolling the compound steel material to a hot rolled strip or sheet which is then annealed at a temperature and for a time period sufficient for the carbon content of the ferritic chromium steel coating layer to be reduced to between 0.001 and 0.003% so as to increase the corrosion resistance of the chromium steel material to that of a superferritic material. After annealing, the sheet may be etched and surface-finished or cold-rolled, recrystallization annealed and thereafter surface-finished, such as temper-rolled. The ferritic chromium steel material has at most 0.1% of carbon prior to annealing. The carbide and nitride forming substance may be titanium whose content in the alloyed carrier material is preferably between 0.50% and 2.00%. The thickness of the ferritic chromium steel coating layer is between 50 and 500 .mu.m, the annealing temperature between 650.degree. and 900.degree. C., and the annealing time period between 8 and 72 hours.

摘要： A compound steel material of high corrosion resistance is manufactured by alloying a carrier material of deep-drawing grade with a carbide and nitride forming substance, compounding the alloyed carrier material with a chromium steel material of normal carbon content, followed by annealing the compound steel material at a temperature and for a time period sufficient for the carbon content of the ferritic chromium steel coating layer to be reduced to between 0.001 and 0.003% so as to increase the corrosion resistace of the chromium steel material to that of a superferritic material. Prior to annealing, the compound steel material may be rolled to a fine sheet. The carrier material used in the method of the invention is a deep-drawing steel of at most 0.12% of carbon, while the ferritic chromium steel material has at most 0.1% of carbon prior to the annealing. The carbide and nitride forming substance may be titanium whose content in the alloyed carrier material is preferably between 0.5 and 2%. The thickness of the ferritic chromium steel coating layer is between 50 and 500 .mu.m, the annealing temperature between 650 and 900.degree. C., and the annealing time period between 8 and 72 hours.
