Shaft

TIME IS MONEY! OPTIMISE YOUR FURNACE AVAILABILITY!

Full and partial repairs of blast furnace shafts are usually precisely planned.

Why? Every ton of pig iron counts! We can offer you “cold” repairs, manually shotcast from a platform installed inside the furnace, usually arranged parallel with other works and a more extensive revision.

But what if the shaft requires an urgent protective repair, for which there is actually no time? Our solution: A shotcreting repair with the shotcrete robot of Beck u. Kaltheuner.

ADVANTAGES OVER SHOTCAST PLATFORM METHOD:

  • Significantly lower installation time
  • Less risk for personnel as the robot is operated by remote control outside the furnace
  • Ideal for partial repairs

What other advantages does our “Shooter” or shotcrete robot offer? The crane can be adjusted horizontally up to 30°. The spray nozzle angle itself can be adjusted between 40 and 50°, allowing for a backspraying of staves, scabs or other cavities. The robot “arms” are hydraulically operated and horizontally adjustable: That saves time during the installation and allows continuous shotcreting until the job is done!

Our shotcrete robot is custom designed and undergoes continuous advancement. Very soon we will be able to offer shotcreting with video surveillance. What does this mean for you? Full transparency with regard to furnace conditions and our installation performance.
