Title: Improvements in electric-arc steelmaking
Inventor: SIBAKIN JAROSLAW GEORGE
IPC: F27D11/08
Filed: 1966-09-02
Abstract: Steel containing 0.02-1.8% of carbon is produced in an arc furnace by first forming a pool of molten iron and then continuously introducing iron-bearing material, especially sponge, in small particulate form into the bath at a rate controlled by reference to the power input so that when the required amount of material has been charged the bath is at the desired temperature and carbon content for tapping.  The initial charge may, apart from fluxes, carbon and any necessary alloying additions such as ferromanganese or ferrosilicon, consist of scrap metal, or the latter may be partially or wholly replaced by sponge. By recarburizing the final bath the process may produce grey cast iron.  The process may be operated continuously.

In the manufacture of an electrode for electro-erosion according to the parent Specification, the carrier metal alloy 1 is cast on to a preheated pattern 2 in a sealed container 12. The alloy 1 is heated electrically in a melting container 10 under thermostatic control and upon withdrawal of a slide bar 30 will discharge directly into a pre-heated mould 13, 14 containing the pattern 2 embedded in a mass 26. The container 12 may be connected through valve 28 to a vacuum pump, such as a water jet pump, and through pipe 20 to a source of protective gas which may be carbon dioxide or nitrogen. Mass 26 may be a water-soluble salt or salt mixture with a synthetic resin binder; after casting and cooling, preferably by water, the salt is dissolved out in cold or warm water and the friable residue is then crumbled away. Alternatively the binder may be rubber, polystyrene, polyacrylate, polyvinyl chloride or an acid-soluble cement; subsequently the binder is dissolved. The pattern 2 is later separated from the alloy 1 and a metal layer is deposited on the contoured surface thereof as described in the parent Specification. In another embodiment, Fig. 2 (not shown), the melting container (10) with a closed lid is disposed above the container (12). The melting may take place in air, in a protective atmosphere or under vacuum. A valved pipe (21) connects the two containers.
