For example, about 50 to 60 minutes is needed to increase the temperature
from room temperature to 600
℃
for DR200. When the current temperature
is supposed to be 25
℃
, it takes about 1 minute to increase the temperature
by 10
℃
, accordingly takes about 60 minute until it reaches to 600
℃
. Add an
