Since the advent of continuous steel casting technology in the 1950s, continuous casting functional refractories have also been born. With the advancement of metallurgical technology, the expansion of steel grades, the improvement of billet quality and the extension of service life, continuous casting functional refractories have also been developed by leaps and bounds to improve flow control, rectification and protection of casting functions, prevent oxidation, increase nitrogen and inclusions. Continuous casting requires its functional refractories (submerged entry nozzle, monoblock stopper, Aluminum Carbon long nozzle) to have good thermal shock resistance, resistance to synthetic slag corrosion, corrosion resistance to molten steel, and suitable high temperature strength.

The requirements for submerged entry nozzle have the following parts:
1.Excellent thermal shock resistance
2.Good corrosion resistance to crystallizer
3.Good corrosion resistance to molten steel, especially the inner hole, which must be resistant to molten steel erosion and chemical corrosion
4.Good anti-blocking performance
5.Good high temperature resistance strength
