Product Description

Continuous casting refractory submerged entry nozzle 

Product Description

It is made of choice material, formed by high pressure in static-pressure vessel and baked in high temperature and oxide-free condition. 

Semi-Automatic PET Bottle Blowing Machine Bottle Making Machine Bottle Moulding Machine PET Bottle Making Machine is suitable for producing PET plastic containers and bottles in all shapes.

Series of Al2O3-ZrO2-C material in the body can be applied to different steel grades. The latest new type of low silica material has more higher thermal stability, erosion resistance compared with traditional materials.
Multi-types for Al2O3 anti-clogging.
1.Inner lining with argon insert
2.Traditional Al2O3 anti-clogging inner lining
3.Low silica&low carbon inner lining
Series of compound materials for slag line.

Features
1.Standard Al-C body materials having corrosion and thermal shock resistances.
2.Standard Al-C materials for the bowl structure having high corrosion resistance.
3.Spinel materials for the bowl structure to assure good resistance to slag corrosion.
4.Standard Mg-based materials for the bowl structure having good corrosion resistance to slag containing Ca.
5.Standard material to prevent Al2O3 adhesion inside the nozzle.
6.Standard argon injection structure to prevent air suction.
7.High quality Zr-based materials to assure good corrosion resistance to the slags with or without F.
8.Ceramic fiber blanket to prevent heat loss during casting.
9.Non-carbon liner to meet the requirements of low carbon steel, silicon steel and high purity steel productions.
10.composite surface materials to assure sealing and fast change
