“…The stress–strain equation as follows: where E is the Young’s modulus, is the Poisson’s ratio, is the thermal expansion coefficient. The refractory linings Poisson’s ratio is 0.15, the Young’s modulus E is 4 GPa, and the thermal expansion coefficient is 5e−6 1/°C [15,16].…”

Hot blast stoves are important equipment used in the iron-making process. Its cyclic operating process consists of an on-gas period and an on-blast period. In this study, a 3D thermal and thermomechanical model of a hot blast stove were used to calculate the temperature and stress distribution during the operating process. The thermal analysis simulation results are compared with the in situ data, and the maximum error was found to be lower than 7%. The results indicated that the maximum principal stress mainly occurred outside of the refractory linings, and the minimum principal stress mainly occurred inside of the refractory linings. The maximum deformation occurred inside of the refractory linings in the combustion chamber. The shell is mainly subjected to the maximum principal stress, where the minimum principal stress only occurred at the junction. The maximum deformation of the shell occurred at the top of the combustion dome.

“…The sheer volume of production demand of these products is related to the increase of the equipment sizes (such as blast furnaces, converters, steel ladles, tundishes, etc.) able to provide the required scale of the output, which also leads the refractories to sustain large mechanical loads and multiaxial stress conditions [2].…”

“…Its advantages are the high homogeneity and the high density of compacts, resulting in aggregates with consistent properties. [13] Even shapes with a high length/diameter ratio can be produced via CIP. [13][14][15][16] In most applications, the raw materials for CIP are granulated or spray-dried to achieve a compactable mixture.…”

[15,17] Furthermore, it was shown elsewhere that a cyclic pressure buildup or a cyclic maximum pressure can lead to higher relative densities and lower apparent porosities.…”

Low Shrinkage, Coarse‐Grained Tantalum–Alumina Refractory Composites via Cold Isostatic Pressing

Alumina–tantalum composites are produced in a two‐step synthesis via cold isostatic pressing (CIP) from commercially available raw materials without any addition of organic additives. The highest densification for fine‐grained composites is found with a maximum pressure of 150 MPa, whereby a cyclic pressure increase or at maximum pressure showed no measurable influence. The increase of the sintering temperature from 1600 to 1700 °C led to a higher densification up to a relative density of 75.8%. Aggregates received by jawbreaking show a blocky morphology, rounded corners, and edges with porosities of 6.2−7.3%. The formation of tantalum carbide and the incorporation of oxygen into the tantalum lattice are verified during sintering. The coarse‐grained composites produced from these aggregates show open porosities of 25.3−25.7% and shrinkage <0.5%. Determined splitting tensile strenghts are in the range between 8.4 and 9.1 MPa.
