What function does nichrome wire serve in the refractory?

Nichrome wire is primarily used for heating applications due to its high electrical resistance and ability to withstand high temperatures. When electric current passes through nichrome wire, it generates heat, which is utilized in various heating elements. In the context of refractory materials, where high temperatures are encountered during processes like melting, shaping, or bonding, nichrome wire serves to safely and efficiently supply this necessary heat.

While both anchoring and structural integrity could be a consideration in the use of materials within a refractory setup, they aren’t the primary function of nichrome wire. Instead, its most recognized role is in the direct heating of the refractory itself, contributing significantly to achieving and maintaining the high temperatures required for various industrial processes.
