Conclusions A relationship was established between certain technological parameters, properties, and structural features of fused periclase.It was shown that the main factors in obtaining high quality periclase are the purity of the raw materials, determining the high MgO concentration in periclase; rational fusing cycle, ensuring migration of the impurities into the skin of the block and governing the features of the structure of the crystals; magnetic separation, permitting the ferromagnetic particles and part of the silicates to be removed; and crushing and milling, ensuring the optimum grain-size composition in the powder.A properly selected combination of these factors will improve the quality of the fused periclase and increase the resistance of periclase thermoelectric heating elements and refractories in service.Translated from Ogneupory, No. 2, pp. 5–10, February, 1979. 相似文献

A technique for nondestructive testing of forgeability of ferromagnetic sheet materials is described. Its underlying idea
is a determination of directions of scallop formation on the base of a formula including the amplitudes of the second and
fourth harmonics in a plot of a magnetization component normal to the external field versus the angle between the directions
of rolling and easy magnetic axis. 相似文献

Computer tomography of refractories that are used in foundry systems for casting and rolling units in order to prepare thin
foil aluminum billets is performed. The question is considered of recycling refractory materials with the aim of their further
use in foundry equipment.
