Maintaining consistent temperatures in a forge requires control over the fuel and airflow. Here are some tips to achieve this:
Ensure proper insulation to minimize heat loss.
Maintain consistent fuel supply (whether using propane, charcoal, or coal) to avoid fluctuations in heat generation.
Adjust the airflow to control the intensity of the flame; more airflow increases the intensity, while less airflow decreases it.
Use a temperature monitoring tool, like a thermocouple or pyrometer, to regularly gauge the forge's temperature and adjust the fuel or airflow accordingly.
