is quite a familiar material, and people have been able to make great big lumps of it during steelmaking processes.
Formation of bcc-iron and iron carbides
is sufficient to explain all features of the presented diffraction patterns, although complexity of the diffraction patterns and limited reciprocal space may preclude their unambiguous interpretation.
For instance, incredibly thin nanowires could be extruded; the diameter of one iron carbide
nanowire was narrowed from 9 nanometers to just 2 nanometers.
The iron carbide
plant would be sited near steel maker Iscor's Sishen iron ore mine and would involve the laying of a gas pipeline from Sasol's plants in the Orange Free State or from the Kudu gas fields off the Namibian coast.
Given these advantages, the successful commercialization of iron carbide
will ultimately produce a net saving for mini-sheet plants of at least $16 per ton of hot band (perhaps much more if the technology works as advertised) compared with the cost of using more conventional DRI products.
Chromium, however, causes chill iron carbide
and intercellular iron carbide
--two enemies of machinability.
The first phase of the project is a bankable feasibility study that will include studies of DRI, HBI, Iron Carbide
, Pig Iron, and Granulated Iron.
Background: Carbides occur when undissolved carbon combines with iron to form iron carbide
Should the iron ore export business get off the ground it could provide the impetus for mineral-based industrial business elsewhere in the region as a proposal to build an iron carbide
plant on the Gabonese coast would provide a market for the ore.
18, 1996--Lockwood Greene announced today that it has been selected by Qualitech, a steel production company based in Indianapolis, Indiana, to start working on a new iron carbide
plant projected to start in August of 1998.
The Industrial Development Corporation of South Africa (IDC) has undertaken a pre-feasibility study for a plant at Phalaborwa, Northern Transvaal, using Pande gas to convert magnetite to iron carbide
in a development costed at $800m.
Under the terms of the agreement, ECT invested $34 million -- $14 million in equity and $20 million in subordinated debt -- toward the development and construction of a technologically-advanced steel minimill in Indianapolis, Indiana, and an iron carbide
production facility in Corpus Christi, Texas.
This may be explained as a result of excessive residual magnesium serving as an iron carbide
stabilizer in ductile iron.
Minimizing iron carbide
formation in iron (to create an easier-to-machine condition) demands that graphite form during eutectic solidification.
A fine pearlite, which is a lamellar matrix structure composed of alternating plates of ferrite and iron carbide
, enhances the cast iron hardness and strength properties.
