The definition of each box and the value range of input
parameter are shown in the following table:
t1 The rst stage heating rate , valid value range: 5-20℃ /min
T1 The target temperature of the first stage, the effective value
range: 300 ℃ -500 ℃
t2 The second stage heating rate , valid value range: 5-15℃ /min
T2 The target temperature of the second stage, the effective
value range: 900℃ -1200℃
H2 Second stage holding time, valid value range: 0-30min

T3 The third stage target temperature, effective value range:
1250℃ -1400℃
H3 The third stage of holding time, eective value range: 0-30min
t4 The fourth stage heating rate, valid value range: 2-10℃ /min
T4 The fourth stage target temperature, effective value range:
1450℃ -1600℃
H4
Fourth stage holding time, eective value range: 0-300min
t5
Cooling rate, eective value range: 5-10℃ /min
T5
Control the temperature for stopping cooling, eective value
range: 400℃— 1000℃
(Note: The input temperature is between 800° C and 1000° C,
and the temperature is lowered according to the cooling rate;
