Patent Number Title Of Patent Date Issued
5304230 Method of disposing of organic and inorganic substances and a plant for carrying out the method April 19, 1994
In a method of disposing of organic and inorganic substances, the substances are gasified and decomposed in and/or above a liquid bath of a metal alloy under negative pressure, off-gases forming are seized, collected and purified and separated.To prevent the formation of health-endangeri
4993689 Convertor for continuously melting scrap with tapping means February 19, 1991
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 ca
4957547 Process for continuously melting of steel September 18, 1990
A process for continuously melting steel from largely already reduced iron containing material such as pig iron and/or scrap iron, in which process the melt is poured into a ladle for performing subsequent metallurgical steps. The metallurgical slag is, by adding flux, adjusted to20-77.2
4950325 Process for heating steel melts and an apparatus for carrying out the process August 21, 1990
An apparatus for heating steel melts covered with a slag rich in iron oxide, and employed in particular for continuous steel making processes such as the KVA process, incorporates a height-adjustable injection lance for supplying metals which react exothermally with the melt and with the
4925489 Process for melting scrap iron, sponge iron and/or solid pig iron May 15, 1990
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-stoich
4895594 Process for continuously melting scrap January 23, 1990
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 ca
4525211 Process for producing a microkilled steel suitable for freerun continuous casting for subsequent June 25, 1985
In order to produce a microkilled steel suitable for free-run continuous casting for subsequent cold forming standardizing of the C - content to .ltoreq.0.05%, preferably .ltoreq.0.03%, Si - content to .ltoreq.0.05%, preferably 0.02-0.04%, and Al - content to .ltoreq.0.006% is proposed.
