Embodiment Construction

[0026] In a known manner, the pear-shaped converter vessel 1 is supported laterally (held by the carrier ring 2 ), wherein the tipping drive 3 can be integrated into the lateral support. Usually, through the upper opening 4 (not shown here) of the converter, an oxygen lance is introduced, through which the oxygen necessary for refining the pig iron melt is brought in.

[0027] According to the invention, this entrainment of oxygen is now replaced by injectors 5 installed in the side wall of the converter vessel, distributed on the periphery, through which the necessary oxygen can be entrained above the bath level inside the converter.

Abstract

The invention relates to a converter for the gas-blown production of steel from an essentially liquid raw material, in particular pig iron.

Description

technical field [0001] The invention relates to a converter for the manufacture of steel. Background technique [0002] In the case of steel production in electric arc furnaces (abbreviated as EAF), in which mainly solids are used, it is known to use additional natural gas burners during the fusion stage for metal scrap. This helps to significantly reduce the demand for electrical energy. [0003] Here, so-called SIS units (SMS=Siemag Injektionssysteme) have been used for some time. [0004] This is a so-called injector-burner combination for combustion, introducing oxygen and possibly blowing carbon through the side walls of the EAF. [0005] The injector is operated in two modes, more precisely, burner mode and injector mode. [0006] In burner mode, the powerful flame supports the fusion of scrap metal in the relatively cool zone of the furnace, ie substantially outside the middle of the furnace. During melting, more precisely in the so-called flat bath phase, the bur...
