Carbon black reactor

Tread  reactor  for  hard  carbon  black  in  a  tread  reactor, extreme temperatures above 1900°C prevail. Reducing atmospheres, water quenching processes and gas velocities  in  the  supersonic  range  require maximum performance and quality in terms  of  mullite  and  corundum  bricks ,  as   well  as  precision  concretes.  Tread reactors  require  precisely  shaped  bricks  to  withstand  high  gas  velocities   and pressure  differences. RATH  choke systems are based on polished bricks, which fit perfectly  together, thereby  ensuring a long service life. RATH carbon black chokes are  made  of  corundum  bricks and chrome corundum bricks. Carcass reactor for soft  carbon  black.  The  carcass  reactor is used to create soft carbon black. These horizontal  or  vertical  reactors  are  operated  at  slightly lower temperatures than tread reactors. The challenge lies in the size and mode of operation of the systems , or  the  high  amounts  of  alkali  additives  that  are often used. The temperatures often do not exceed the 1600°C limit and therefore allow lining with mullitic bound corundum bricks.

Claus reactor

The Claus reactor as part of the sulfur recovery system is just one example of where high performance materials are used.

Typically, mullitic bonded precious corundum bricks are used to guarantee long, maintenance-free operation.
