A Sampling of Our Work

Quality From Start To Finish

 

This is a ceramic internal burner in a silica stove. The refractory had failed and required replacement. TRE devised a way to keep the stove hot and repair the burner.

The burner was repaired and placed back in service in under four weeks. The stove kept hot and returned to service days after the repair was complete. There were no injuries on the job.

TRE performed a stove assessment which determined that the combustion well of the stove was collapsing. TRE designed a repair for the stove which retained most of the stove internals and gave the stove an additional 10 years on a 13 year campaign.

The repairs to the combustion well were performed without replacing the checker column. The checker column was braced and secured. There were no accidents on this job

The dome of the stove was replaced as it was not in good enough condition to warrant a ten year campaign extension. The dome and combustion well repairs cost one forth of what a complete stove internals replacement would cost.

TRE performed an assessment on the stack refractories of a furnace and found the wear to be severe. The customer needed to bring the furnace down and considered performing a shotcrete job. After analysis it was determined that a brick veneer job would last three times as long as a shotcrete job but would only take the duration of two shotcrete jobs. The customer decided to have TRE engineer a brick veneer job for the furnace. The job was completed in less than four weeks.

External Taphole repairs

While TRE performs many repairs we also have the capacity to redesign the refractory system for your blast furnace hearth, bosh or stack.

Tapping the salamander is done to reduce the level of iron to below the repair increasing the safety during an external brick repair, or to speed up the cool down and tearout for a hearth reline. Tapping the salamander assures that upon reheating the salamander does not expand and crush the hearth wall refractory and/or crack the shell. Tapping the salamander should be considered whenever the furnace is going to be down for an extended period of time over which the salamander is likely to freeze.

A key consideration for salamander tapping is the size and angle of the hole and associated trough. The iron must be able to run through the hole and drain to the level of the tap.
