| 　　Ceramic coated pipe is a carbon steel pipe with multiple, thin layers of ceramic coating outside and in. The ceramic coating is resistant to slag attack and extends the life of the pipe when it is immersed into molten metal or in high temperature atmosres. The applications include powder injections, tap-hole cleaning and opening nozzles in ladles, tundishes and launders. | ||
| 　　Ceramic coated pipe was developed to increase the lance life beyond conventional calorized or black pipes. Due to innovative methods of refractory deposition for interior and exterior coatings, it provides unequaled lance life at lower cost. A special ceramic coating has been developed for copper smelter applications. | ||
| 　　Ceramic coated pipe is used to inject oxygen or other gases into the submerged electric furnaces. The pipe provides a much longer life in the high-temperature furnace environment than previously used stainless-steel pipes. Using Ceramic coated pipe to inject gas in submerged electric furnaces reduces costs and downtime for smelter production. | ||
Some of the various uses of Ceramic coated pipes include the following:•-Cutting scrap, raising bath temperatures and decarburizing•-Opening nozzles in tundishes and ladles•-Injecting carbon and other powders into the electric furnace and ladle•-Opening the iron notch of a blast furnace•-Injecting argon into ladles•-Injecting argon and oxygen into the aod•-Injecting flux for degassing in aluminum melting furnaces To enumerate the advantages of these pipes in oxygen steel making process are: -The exothermic reaction and agitation promote decarbonisation and heat rise in the furnace, while foaming slag can be eliminated. -Fusion of sub material can be accelerated -As the process raises the temperature -Quality of steel will be improved -Selection of raw materials to be charged becomes easy -The process raises the production capacity of an electric furnace -Hydrogen, Nitrogen and non-metallic inclusions can be eliminated through oxidation -It makes it possible to recover chrome with the use of high chrome steel scrap | ||
