DRY OUT Process Stages

The surface of the material is heated without flame licking, reaching 150°C with hourly increases of 25°C.

A. FIRST WAITING PERIOD (100°C-200°C) EVAPORATION OF MOISTURE IN THE SUBSTRATE (DRYING)

Between 100°C and 200°C, it will be waited for a minimum of 48 hours, without exceeding the conditions and not before the steam is exhausted. It may take approximately 72 hours. When the steam starts to escape, the chimney covers should be half-opened to prevent steam buildup inside.

The refractory surface is heated only by heating without flame touching, reaching 200°C with hourly increases of 10°C.

B. SECOND WAITING PERIOD (350°C-550°C) EVAPORATION OF CRYSTALLINE WATER IN THE SUBSTRATE

Between 200°C and 400°C, it should be waited for a minimum of 48 hours until the steam emission stops. It may take approximately 72 hours. If necessary to allow steam to escape, all chimney covers should be fully opened, and other covers should also be opened until steam emission stops. In this temperature range, if areas are felt excessively hot from outside, holes are drilled from the outside to be subsequently closed with welding to ensure easy steam escape.

With hourly increases of 15°C - 20°C, it reaches 400°C.

C. THIRD WAITING PERIOD (400°C- 600°C) BEGINNING OF SINTERING

If there is steam emission at this temperature, it should be waited at the temperature where steam emission begins. After steam emission stops, it can be waited for up to 36 hours.

With hourly increases of 25°C - 35°C, it reaches 600°C.

D. FOURTH WAITING PERIOD (600°C-1450°C) END OF SINTERING TRANSITION TO CERAMIC PHASE

A minimum of 8 hours of waiting is required. At the end of the waiting period, the operating temperature should be reached, and the furnace can be put into operation. Alternatively, the furnace can be cooled using the attached cooling program.

With hourly increases of 35°C - 50°C, it reaches 1450°C.
