Refractories are a very significant cost element on the construction of furnaces and do require occasional maintenance and even downtime for repair, which is never a welcome prospect for any operation manager or business owner. We at Therser fully understand how critical a component your refractory linings are to the operation of your business and how urgently it must be brought back into service with as short an outage duration as possible.
Brickwork in kilns and furnaces are extraordinarily resilient and long lasting, despite the stresses it undergoes at every firing/cooling cycle. Even when it seems to be almost flaking away, it can still withstand temperatures of 1700C / 3092F. Despte that, there comes a point at which old and damaged refractory bricks degrade to the extent that they do begin to exact a cost on productivity through inefficient heat retention and even damage to the kiln ware from dust or particles falling off the bricks.
