{2. Quid factores afficiunt servitium vitae refractórium materiae?
The service life of refractory materials is affected by many factors, including temperature, chemical erosion, mechanical stress and thermal shock performance. First of all, temperature is a key factor. High temperature will cause the melting and decomposition of refractory materials, thereby reducing their service life. Secondly, chemical attack, such as acidic or alkaline gas and liquid penetration in the furnace, will cause corrosion and deterioration of refractory materials. In addition, mechanical stress and impact, such as slag impact, load changes, etc., will cause mechanical damage and cracking of refractory materials. Finally, thermal shock resistance, that is, the ability of refractory materials to resist cracking when the temperature changes sharply, is also an important factor affecting its Vita {{VI}}
{3. quam eligere ius refractórium materia?
Sunt plures factores ad considerans cum eligens ius refractórium materia, comprehendo ad operationem temperatus, in eget proprietatibus elit, mechanica et in primis} {I}, ut electus, {{I}} considered, such as choosing silica refractory materials in acidic environment and magnesium refractory materials in alkaline environment. In addition, mechanical stress and impact should be considered, and materials with good mechanical strength and toughness should be selected. Finally, for environments that require frequent heating and cooling, refractory materials with good thermal shock resistance should be selected to prevent cracking and Spalling {{{IV}}
