Future issues of Refractory technology
- Durability of refractory for pairing nozzles and side dams determines the success of strip casting.
- Technology of mass melting of scrap in converter by using post combustion requires super- high temperature refractories.
- Super fine powder processing technology to produce refractory.
- Use of monolithic refractory in steel making and refining furnaces require to automate brick laying and intelligent repair.
- Nano tech refractory is thermal shock and corrosion resistant The nano-particles act in two ways
- They consist of mono spheres and improve properties like elasticity and strength
- Control of molecular structure as the particles have many small pores of several hundred nano meters.
