Furnace lining refractory is a refractory layer used to protect the interior of the furnace and heat treatment equipment. Furnace lining refractory materials need to be able to withstand extremely high temperatures, usually above 1500°C. They have good thermal stability and thermal shock resistance, maintaining structural integrity and stability.
Furnace lining refractory materials need to have appropriate thermal conductivity properties in order to conduct heat effectively and ensure uniform temperature distribution. Low thermal conductivity reduces energy loss.
Furnace lining refractories need to have sufficient mechanical strength to withstand loading and thermal stress. They should have certain compressive and tensile strengths to avoid cracking and deformation.
Furnace linings in the metallurgical industry are often exposed to acidic, alkaline and various corrosive gases and liquids. Furnace lining refractories need to have good erosion resistance to protect the interior of the furnace from corrosion and erosion.
Some refractory materials required in the furnace lining have good plasticity and processability, and can be shaped or poured according to the needs of different shapes and sizes, so that they can adapt to various equipment structures.
