Silicon Nitride Ceramic Welding Rolls for ERW welding

Product Description

Ceramic silicon nitride welding rolls for use in electric resistance welding (EWS). EWS is used to fabricate steel pipes & tube

sintered silicon nitride (SSN)

gas pressure sintered silicon nitride (GPSSN) or

hot-pressed silicon nitride (HPSN)

In comparison reaction bonded nitride (RBSN) - starting substance Si-powder - is nitrided shrink free in a specifically set N2-atmosphere.
