  • Patent number: 4913734
    Abstract: The hereinproposed method and furnace provide for preliminary building up of melt in a melting pot (10) of a rectangular shape in the horizontal section, delivery of an oxygen-containing gas (3) into the melt below its surface level through tuyeres (13) with nozzles (14) installed in the longer walls of the melting pot (10) creating two melt zones: an upper zone (9) loaded with solid carbon fuel (2) in an amount sufficient for providing a volumetric concentration of said fuel within 0.5 to 50% of the melt volume in said zone (9), wherein said concentration is maintained by subsequent concurrent loading of iron-bearing material (1) and solid carbon fuel (2), and a lower zone (8) consisting of a layer of slag (4) and a layer of ferrocarbon intermediate product (5) said layers being discharged separately through channels (17 and 18) made in the counterproposed short walls of the melting pot (10).

  • Patent number: 4214856
    Abstract: An apparatus for delivering a refractory mass with a sand-blast head along a ladle-lining surface and parallel thereto in a ladle. The sand-blast head is provided with a movement inside the ladle so as to continuously fill the lining along a helical trajectory and over the entire height of the ladle from the bottom to the top. For this purpose, the apparatus is mounted on a platform installed inside the ladle on a hollow supporting rod through which the mass is fed to the sand-blast head. Provision is made for a contact sensor which senses the current level of the lining plane, and controlled drives of the platform rotation, rod lifting and change in the radial jet of the mass thrown out of the sand-blast head.
