Tidbit Refractory, a mixture of stone and sand, protects a blast furnace from melting even at 1,500℃. Tidbit Normally, iron ore and oxygen are tightly bound. However, oxygen must be separated from the ore
A refractory refers to materials that can withstand high heat. through the ‘reduction process’ that is absolutely necessary to make steel.
