In industrial applications, common problems of refractory materials include thermal damage, chemical corrosion, mechanical wear and spalling. Thermal damage refers to the melting, decomposition and cracking of refractory materials in a high temperature environment. Chemical corrosion is the chemical reaction between refractory materials and gases and liquids in the furnace, resulting in material degradation. Mechanical wear is damage caused by the impact and friction of slag, material flow, etc. Fɛn minnu tɛ se ka wuli, olu sanfɛ. spalling bɛ kɛ a ka c’a la fɛnw sanfɛ minnu tɛ se ka wuli, k’a sababu kɛ funteni caman yeli ye, kemikɛli kɛcogo walima masinw ka degun, o bɛ nɔ bila fɛnw ka baarakɛcogo bɛɛ lajɛlen na ani u baara waati la. ka ɲɛsin nin gɛlɛyaw ma, sɛgɛsɛgɛli ni ladonni bɛ kɛ tuma bɛɛ, ani fɛnw ni jɔli taabolo bɛnnenw ka kan ka sugandi ka ɲɛsin fɛnw ma minnu bɛ se ka kɛ sababu ye ka fɛnw falen u la.}}}
