Inspection & Repair
Lancescope inspections unitize a digital image recorder and LCD monitor that records images taken by micro cameras at the end of a water-cooled lance enabling the ability to subject the inspection equipment to be 1,650°C.
Endoscope inspection can also be carried out with a probe length of 47" (1200mm) to set high quality still images in certain zones.
The ceramic welding process utilizes a dry mixture of refractory powder and metallic fuels. This mixture is projected onto the area to be repaired using custom-made air and water cooled lances. Conveyed by a stream of oxygen, the mixture ignites on the hot repair surface in an exothermic reaction in excess of 2,000°C.
Upon impact, the material coalesces with the brickwork, forming a ceramic bond and restoring the refractory to its original state. The flow rate of welding powder during repairs can be increased up to 770 lbs/hr (350kgs/hr) to ensure faster repairs in short shut-down periods to minimize downtime.
