  RELATED SERVICES  

  FURNACE   HOTWORK SERVICES  

REFRACTORY DRY OUT

Controlled heating and ventilation of a furnace to remove all moisture in refractory mortars and monolithic materials. Our technology uses portable gas or diesel-fuelled high-velocity burners that provide uniform temperature distribution, enhancing the furnace's refractory lifetime.

 

FURNACE HEAT-UP

Achieving uniform temperature distribution throughout the furnace using high-velocity burners, which ensures efficient operation and optimal thermal performance. Our systems ensure precise temperature control, eliminating hot-spots and stagnant areas within the furnace.

 

FURNACE EXPANSION/CONTRACTION CONTROL

Timely adjustment of furnace steelwork during refractory expansion or contraction is crucial for furnace stability and lifespan.

 

GLASS FURNACE CULLET FILL IN

Gradually feeding raw material into the system while controlling temperatures until a constant flow of glass throughout the furnace is achieved, allowing production to commence efficiently.

 

FURNACE ONLINE REPAIRS

Essential for continuous operation in metals smelting and mineral processing, these services ensure equipment remains efficient and operational without unexpected shutdowns. Techniques include flux line and throat-over coating, repairs to furnace crowns and roofs, and sealing of rat holes and expansion joints.

 

ON-SITE HEAT TREATMENT

Advanced pre and post-weld heat treatment techniques to minimize thermal stress and enhance material integrity, applicable to pipework, pressure vessel repairs, and high-strain area treatments.
