Furnace heating up crowns the building up of new or repaired melting aggregate. Together with cullet filling there are activities that bring the furnace to the operational stage. The quality of work is very important and has a great influence on the further furnace operation quality and sometimes on the lifetime too. Bohemia Hotwork (BHW) uses for heating up efficient high velocity hot-air gas burners and by the choice of the right funs is ensured the necessary overpressure in the furnace. The temperature control is practiced by special control damper. It makes possible to follow the prescribed heating up curve with very high accuracy 2-3 °C.

For the furnace heating up we use the most modern measurement equipment with values registration on PC. All the measuring data – temperature (°C), overpressure in the furnace (Pa) and main crowns and regenerator crowns lifting up are the property of customer.

Our skilled workers are ready to check the refractory expansion and execute the furnace anchoring during the heating up process.

We execute this process by the help of the burners set using for the heating up. We follow the prescribed curve. This is a process of the furnace control cooling down on the requested temperature. This is used for the furnaces that will be after particular repair heated up again and put to the operation. For the cooling down as well as for heating up we execute the control anchoring.
