Patent GB-956270-A (GB)
Title: Process for the production of refractory materials
IPC: C21C5/44
Filed: 1960-05-03
Abstract: In the production of refractories by the agglomeration of sintered magnesias at least two size ranges of magnesia are employed having been separately sintered to different densities. The "coarser" grains of magnesia have been sintered to an apparent density greater than 2.8 g./cm.2 whilst the "finer" grains have been sintered to an apparent density of less than 2.8 g./cm.2  "Coarser" and "finer" in the above sense are defined respectively as greater than and less than 1/10 of the "gross diameter" of the grains.  The "gross diameter" is the arithmetic mean of the smallest and largest grains present in a classified sample containing the largest grains and representing 20% by weight of the mix to be formulated.  It is also possible to employ two magnesias of which the coarser is that having a diameter greater than 1/8 of the "gross diameter" and the finer a diameter less than 1/12 of the "gross diameter."  The intermediate size range in such a case can be absent, or partially or wholly made up of magnesia of any density. The finer grains are preferably pure magnesia whilst the coarser are preferably less pure, for example dolomitic magnesia.  The fine grains may be coated with carbon or graphite to provide a 2-15% carbon content by mixing the partially sintered fines with an organic material and heating in a neutral or reducing atmosphere to 400-2000 DEG  C. after which they are reground. Organic binders or reducing materials such as tar, pitch, carbon or graphite may be added to the mixture of magnesias. Chromite grains may also be added.  An example relates to the production of a converter bed. Of the total magnesia required, 20% by weight will contain grains between 12 and 20 mm.  The "gross diameter" is hence 16 mm. The coarser portion of the mix has a minimum diameter of 16/8 , i.e. 2 mm., and this is made up of a magnesia sintered to a density of 3 g./cm.3.  The finer portion has a maximum diameter of 16/12 , i.e. 1.3 mm., made up of sea water magnesia sintered to a density of 2.6 g./cm.3.  An intermediate magnesia of 1.3 to 2 mm. size may also be added, this having been sintered to a density of 2.9 g./cm.3.
