High temperature mechanical characterisation of an alumina refractory concrete for Blast Furnace main trough

High-temperature mechanical characterisation of an alumina refractory concrete for Blast Furnace main trough

“…1 This facility is composed of a 400 kN electromechanical testing machine equipped with a 1600 • C furnace capacity. The specificity of this apparatus resides in the fact that a special device located outside the furnace enables the differential displacement measurement of the high and low faces of the specimen for a temperature ranging from room to 1500 • C. The LVDT sensors then measure the specimen height variation leading to a direct strain measurement.…”

“…In order to fit close to the real material service conditions, the material will been tested in oxidising or reducing atmosphere for which a specific technique has been developed. 1 Other parameters such as scale factor or influence of lubrication will be also investigated.…”

Cyclic Temperature Loading Residual Flexural Strenght of Refractory Slabs

“…In general, refractory cement composites are characterized by excellent toughness, mechanical properties (compressive and flexural strength), thermal shock resistance, low permeability and higher porosity, etc. [2,3]. Fibre reinforced cement composites suitable for high temperature applications have to satisfy several conditions.…”

In situ observation of the dissolution phenomena of SiC particle in CaO–SiO2–MnO slag

“…[1][2][3][4][5][6] There are some traditional ideas for the dissolution, i.e. local corrosion of clay-bonded carbide refractory into the slag due to an accelerated mass transfer caused by the Marangoni flow in an interfacial reaction film.…”
