A method for the treatment of metal melts, in particular iron - and steel melts

摘要

during the different stages of the behandlungsverfahrens for stahlbereitung there is conflicting prozeu00dferfordernisse. the method and the system of the invention generates the appropriate treatment conditions for the various phases of the behandlungsverfahrens. $a iron or molten steel (2) through the blistering of a gas flushed.a refractory ring (10) is at the beginning of the treatment part of the molten steel in a much schlackenfreien spu00fclfleck immersed to the limited schlackenfreie surface to form.the molten steel is then with the addition of exothermisch reacting heating, such as aluminum and oxygen, on the sauerstofflinie (7) and on the aluminium fu00f6rderungsrohr (9) heated.as soon as the steel to the predetermined temperature, the refractory ring (10) from the melt and the air volume of the lifting of the liquid steel in the ladle with a hood is excluded. desulphurization of steel.
