Title: Improvements in or relating to a method of reduction refining of cast iron alloyed cast iron and hypereutectoid carbon and alloyed steels
Inventor: IWASE KEIZO
IPC: C21C1/00
Filed: 1954-09-29
Abstract: A process for the production of cast iron, alloyed cast iron, and hypersentectoid and alloyed steels having short-flake or nodular graphite comprises refining a charge under a reducing slag of which the major proportion consists of one or more oxides, carbonates, or fluorides of the alkali or alkaline earth metals and one or more of carbon, silicon, or aluminium in an amount 1/2 to 1/50 of the weight of the oxides, carbonates or fluorides, the constituents being intimately mixed and pulverized to a size of at most 0.5 mm.  The charge may comprise scrap cast iron, pig iron, scrap steel, and lathe turnings or chips and the slag may contain a minor proportion of alumina, silicon or magnesia.  When lathe turnings or chips are included in the charge they should be mixed with slag before charging to prevent oxidation.  Any type of furnace may be used and the melt is retained therein under the slag until a test sample shows the required graphite structure.  The slag produced during melting may be removed and replaced by a fresh slag.  The metal may be innoculated before casting by a graphitizing reagent which results in a modification of the structure shown in the test sample.  The process is stated to produce a metal having a more or less constant hardness throughout its cross-section.
Patent GB-281338-A (GB)
Abstract: 281,338. Duffield, F. L. Nov. 29, 1926, [Convention date]. Rotary furnaces.-The roasting and reduction of metallic ores are effected in two rotary furnaces, which are used alternately for the roasting and reducing operations. The apparatus shown for the treatment of iron ores and the refining of the metal comprises two rotary furnaces a of truncated conical form arranged in axial alignment with their narrower ends registering with a fixed structure b containing a conduit f, through which gas from a producer g can be supplied under control of a valve m to one or other furnace, a conduit h for the transfer of gas from the reducing to the roasting furnace, and air inlets l. In operation, assuming that roasting and reduction are being effected in the right- and left-hand furnaces respectively, gas from the producer wall be supplied to the left-hand furnace, and, after acting on the ore, will be exhausted through the conduit h. Some or all of the gas will then be burnt within the right-hand furnace with air supplied through the corresponding connection l, and the products will be exhausted through the uptake k. When the reduction of the ore is completed the left-hand furnace is tilted to discharge its contents into the refining furnace o, and a fresh charge of ore is supplied. Gas is then admitted to the right-hand furnace, which becomes the reducing furnace, and the waste gases therefrom are burnt in the left-hand furnace for roasting the freshly-charged ore. Any gas from the reducing- furnace, which is not needed for the roasting operation, may be utilized for the production of electricity, or for the generation of fresh reducing gases. Such surplus gas is drawn off through the pipe p, which communicates with the conduits h through a dust trap. The refining-furnace may be electrically heated, and may be supplied with gas from the pipe p. The furnaces are provided with internal projections to shower the ore during rotation. Powdered or liquid fuel, supplied with air, steam, or a mixture, may be used instead of gas. In the Specification as open to inspection under Sect. 91 (3) (a) it is stated that the process and apparatus can be used for the two-stage treatment of materials other than metallic ores, such as the calcination and sintering of dolomite, lime, magnesite, bauxite, sillimanite, clay, &c. This subject-matter does not appear in the Specification as accepted.
