Calorised Ceramic Coated Lance
Description:
Calorised Ceramic Coated used a low carbon special thin walled pipe, which is calorized and coated with ceramic materials on both the inner and outer surfaces. In steelmaking, pipes are used for oxygen injection and under this high temperature and severe environment, normal steel pipes that are used as lance will be consumed fast. When using Calorised Ceramic Coated Lance, the consumption rate will improve 6-7 times.
