Modeling the thermal and mechanical properties of multilayer refractory linings

Literature review
Background:
A refractory material is the type of materials that maintain its strength at high temperatures. ASTM C71 definition for refractories is "...non-metallic materials which own chemical and physical properties that causes them to be applicable for structures, or as a part of the systems that are exposed to heat above 1,000 °F (811 K; 538 °C). (ASTM Volume 15.01)
This kind of materials can be used in for incinerators, furnaces, reactors, and kilns. They are also are very applicable to be used in making molds and crucibles for metals and casting glass and for lining the systems of flame deflector for rocket launch structures. Today, the …show more content…

The oxides of silicon (silica), aluminum (alumina) and magnesium (magnesia) are the most important materials that usually used in the manufacturing of refractories. Another oxide usually found in refractories is the calcium oxide (lime). Fire clays are also widely used in the manufacture of refractories. (Groover, Mikell P., …show more content…

M. Zubashchenko1 and I. N. Kuzin1 in (2005), studying engineering thermal properties of multilayer linings through curtailing the consumption part of the heat balance of a particular furnace or a heat-powered unit in order to minimize the consumption to extend its lifespan The modular high-temperature heat-insulating lightweight materials ( MHTLWM) is a set of space-oriented multilayer refractory heat-insulating materials which is assembled into a module and aimed to solve a multifunctional engineering task in the heat-powered unit. The development of a lining for a MHTLWM-based furnace and heat-powered units is a challenging task which involves a compromise between the requirements not infrequently contradictory, placed on the refractories’
