3. FIRST HEATING

Following conditions should be considered, directions must be applied step by step, and the importance of the first heating process should be kept in mind, when BFMF-1200-20 Furnace is operated and heated up for the first time.
3.1-Enough free field, surrounding the furnace should be kept. Recommended distance is minimum 30 cm. This free space will increase the furnace performance because of air circulation. At the same time, any fire or explosion danger which may occur due to any material left around the furnace. Please don’t forget, when the furnace reaches to high temperatures, the surface of the furnace reaches to high temperatures too. Any flammable and explosive material which is close to furnace can be a reason for the fire or explosion danger.
3.2-Electricity plug should have proper ground connection and plug should have proper capacity (Cable thickness) according to maximum ampere of the furnace.
3.3-Some gas and fumes due to some chemicals which is used on the electronic parts, in the isolation materials and due to outer furnace surface paint can be harmful if it is breathed directly, during the first heating process. Protective glasses and breathing masks should be definitely used, during first heating and very good air circulation in the working room should be kept.
3.4-During the first heating up process, furnace should be heated up according to following temperature-time table
Heating up to 1100°C
Waiting for 1 hour

30 PROGRAMS
HEATING PROGRAM–1
Chamber temperature, temperature heating rate, temperature waiting steps, waiting times can be set by this menu option. Programs which are called 40, 50, and 60 are similar options for other program settings.

Values can be set, as it was explained in title; ‘OPERATING BY MENU ‘. ‘MOD’ is character of heating process that means ‘DIRECT’ or ‘STEPPED’ heating. ‘RAMP’ is to determine the heating rate which specifies the time to let your furnace reach to set maximum temperature of the steps of the heating programs.

Heating rate can be selected between 10°C/min-25°C/min. If you tend to choose higher value than 25°C/min, ‘Maximum’ appears on the display. On this mode, furnace heating rate is set maximum value automatically.

“Temp-1” indicates the first step where temperature is kept stable/constant for the stepped program. If ‘’Direct heating’’ is set, ‘Temp-1’’ is target temperature for a continuous heating without any waiting step. ‘’Waiting Time’’ is time to keep the temperature of furnace stable at the set value. Depending on the set values, furnace heating continues to reach the next target temperature, after the step temperatures time is ended.
If ‘’ Direct Heating’’ program is chosen, “Temp-1” is the value to keep the furnace stable at the set temperature, as soon as target temperature is reached for the program. If waiting temperature is tended to be decreased after value 1 is reached, waiting temperature is set as ‘Infinite’. In this mode, heating program can be stopped manually.


Menu 33, 34 ve 35 options can be processed, if stepped program is chosen. If you would like to skip any step, step temperature should be set as ‘0’. For example, if you need to use 3 step program ending at 965°C, you should set your third step temperature as 965°C and fourth step temperature as 0. When the third step is over, fourth step is not considered and all heating program is ended after the third step.
