Hearth roll coating
Hello members, Have a good day.
I am looking for the right ingredients for the hearth roll coating.
Hearth roll in galvanizing line(CGL) has different tempetature and usage characteristics for each section.
I would like to know the coating materials and coating equipment(HVOF,APS,etc) suitable for temperature and use characteristics of each section( wear, oxidation resistance, Manganese build up resistance,etc) for furnace.
In addition, What kind of atmosphere is used in the hearth roll of LCO-17 of PRAXAIR?

Hi, Kim Jong Hun

Do you mean hearth roll for continuous annealing?
or rolls for CGL?

LCO-17 is used for build-up protection of annealing rolls. Spraying on the air.

Best Regards,

Hi Vig
Thank you for answer.
Hearth rolls are used in annealing lines.
Cr3C2, MCrAlY(M=Co,Ni) base compositions are alse used as coating materials.
Do you know what kind of atmosphere is used?
I want to know if there are any materials to use as a substitute for LCO-17
