Tratare termică continuă: Cuptoare cu furtun liniar 

Carbolite can supply units to process a single strand. However, for cost efficient production furnaces with up to eight lanes are offered as standard and additional lanes can be added (up to a maximum of 22).

The furnace length is determined by the throughput requirement. The strand passes through Inconel or ceramic tubes and, where required, under the appropriate atmosphere and water cooling (for controlled hardening). A burn-off flame on each tube ensures complete combustion of exhaust gases. Long life wire heating elements are wound around ceramic tubes and are located in both furnace halves. Individually controlled zones provide excellent temperature uniformity which is especially important when heating long lengths.

Depending on tube length and customer requirement, Carbolite can supply a variety of tube supports and tube tensioning systems which ensure the work tubes remain straight. A hinged furnace top allows ease of servicing and cleaning. Low thermal mass insulation ensures fast heat up rates and excellent thermal efficiency. Carbolite offers controls for inert and reactive gases such as cracked ammonia and hydrogen.
